Gas boilers are independent of electricity. Pros and cons of energy-independent gas heating boilers

Let's figure out how a gas boiler works and consider its main components. Outside there is a casing, at the bottom of which there is a control panel. It contains power buttons, operating mode selection buttons, a pressure gauge and a thermometer. In modern models there is also a screen on which information about the status of the equipment and error codes in case of breakdowns is displayed.

One or two chimney pipes emerge from the top. One is installed in models with an open combustion chamber; it is immediately discharged into the chimney, as in the Immergaz Nike Star E series. Two in devices with a closed combustion chamber, such as Bosch Gaz. Using a corrugated pipe, they are connected to a coaxial chimney, and then it goes outside.

Below there is a fan to remove combustion products. A primary heat exchanger is installed underneath it. To the left or on back side The housing contains an expansion tank. At the bottom of the heat exchanger there is a combustion chamber, inside which there is a burner, a transformer and ignition electrodes.

The lower left side houses the circulation pump, three-way valve and secondary plate heat exchanger (in dual-circuit configurations). To the right is the electronic control board and gas valve.

A pipe with coolant is inserted from below, which is connected to the circulation pump and the inlet to the heat exchanger. A pipe goes down from the heat exchanger to connect to the heating system. Gas and running water are also supplied from below for the hot water supply system.

Operating principle

Cold coolant enters the boiler and is directed to the heat exchanger using a circulation pump. If its temperature drops below the one set in the settings, the device should work for heating. Gas is supplied to the burner through the gas valve, and it ignites using ignition electrodes.

A three-way valve switches the operating mode to DHW or heating priority. The fan removes combustion products and provides oxygen into the combustion chamber. The expansion tank is necessary so that coolant enters it when its volume changes due to temperature changes.

When the coolant temperature reaches the level set in the settings, gas stops flowing into the burner and the fire goes out. Sometimes the system has a room thermostat, and then the device will turn on when the room temperature drops.

DHW operation

Smoke removal

In a turbocharged column with a closed combustion chamber, two pipes come out from above. The first of them is an air intake, through which oxygen enters the chamber. The second chimney, through which combustion products escape into the atmosphere. Air circulation is ensured by a fan installed either at the very top or under the burner.

In atmospheric models, only one chimney is installed. The air in the combustion chamber in such devices comes from the room in which it is located.

Protection system

All signals from the safety automation are transmitted to the electronic control board. It is prohibited to independently repair or make changes to the safety system of your home boiler.

Types of boilers and distinctive features

Although both new and old boilers are designed almost identically, there are several fundamental differences depending on the purpose and type of model.

Usually gas boilers volatile ones, for example, Protherm “Cheetah”, they require electricity to operate the circulation pump, ignition and fan. But there are also non-volatile models. Let's look at how a device like the Aton Compact works without electricity. It is mounted with open circuit heating with natural circulation, and ignition is done manually. In order for such a device to work correctly, it is important to comply with all installation requirements.

The devices differ in the material from which the primary heat exchanger is made. It can be steel, copper, cast iron, aluminum and stainless steel. Each of these materials has its own advantages and disadvantages and is selected according to the specific requirements of the consumer. Thus, Conord KCHG series devices are equipped with cast iron heat exchangers with a long service life.

Depending on the installation method, boilers can be wall-mounted, floor-mounted or parapet-mounted. A parapet apparatus, such as the Vulcan “P” series, is always equipped with a closed combustion chamber. It must be installed on the external wall of the room in order to remove the coaxial chimney through it. Wall-mounted units are more compact, making them suitable for small apartment, and floor-mounted ones with increased power.

Parapet boiler

A number of models can only operate on natural gas, like Keber boilers, and some boilers are also adapted to liquefied gas in cylinders. This is relevant if you plan to heat a room in an area without a centralized gas pipeline.

Single-circuit boilers are intended for heating only. Double-circuit devices are equipped with bithermic or secondary plate heat exchanger. The second circuit is used to provide DHW.

Furnaces made of metal and brick - work without electricity or gas

The most convenient type of fuel is natural gas. With its help you can heat houses of any size, public buildings and even huge industrial facilities. It is not surprising that the vast majority of private home owners choose gas as a fuel. What to do in cases where there is no way to connect it? Freezing in a country house? Use electric heaters, paying enormous monthly sums for the kilowatts consumed? Of course not! There are many options that make it possible to organize high-quality heating private home without the use of gas and electricity.

Heating a country home can be done by:

heating stoves (made of stone, brick, metal) and fireplaces;
solid fuel units;
heat pumps;
natural renewable heat sources (wind turbines, solar panels).

The easiest way is to build a classic brick stove in your house and use it for heating. It is important to correctly place such a structure in the home. Ideally, it should stand in the center of the house so that its walls open into different rooms. The stove can be heated with coal or wood. The first option is more rational. Coal burns for a long time and produces a large amount of heat. There will be more hassle with firewood. You will have to harvest them yourself or buy them in large quantities, since the wood burns very quickly.

Let us immediately note that a common person He is unlikely to be able to build a brick oven with his own hands. Its installation requires the creation of a foundation - a dirty, time-consuming and labor-intensive procedure. And it will not be easy for a home craftsman to make the correct brickwork. A reasonable alternative to classic heaters are ready-made stoves made of metal.

Specialized stores offer a chic assortment of cast iron and steel potbelly stoves. They have a high rate useful action and a great view. Thanks to this, factory-made metal stoves make it possible not only to heat the house economically, but also to make the residential interior original. It is easy to equip both a conventional stove and a ready-made potbelly stove with a coil. It will heat water, which can be supplied to radiators installed in different rooms Houses. With this approach, we will get economical heating powered by wood or coal.

Fireplaces can also be used to heat homes. But only if the home has a small area. Big house with many rooms and utility rooms. The fireplace will not be able to heat the rooms. In most cases, such heating structures play a decorative role.

Features of non-volatile boilers

Heating boilers are divided into two large categories - volatile and non-volatile. The first has many advantages:

More accurate temperature maintenance.
More service functions.
Possibility of working according to the program.
High level of security.

There are also disadvantages - they create additional electricity costs, have too fragile electronic filling, and do not work in the absence of electricity.

It would seem that having a modern double-circuit boiler in your home is cool and convenient. But behind the convenience lies the need to have an auxiliary source of electricity. Such sources are generators and uninterruptible power supplies on batteries. In any case, the consumer will face additional costs for fuel and batteries.

Non-volatile heating boilers can operate without electricity. They use mechanical control systems that control the temperature of the coolant and the operation of all components. Their efficiency indicator may be lower than that of electronic models, but there are also quite energy-efficient models (such distortions are observed in all lines of heating equipment).

Advantages of gas boilers non-volatile type:

No dependence on power sources - if the lights go out in the house, the heating will continue to work.
A simpler internal structure - without flimsy electronics that are not resistant to power surges.
They can work for both heating and hot water supply - double-circuit gas boilers are available for sale.
Possibility of working in houses without electrification - for example, in rural areas or in the outback.

Many well-known brands are engaged in the production of non-volatile models - Protherm, Lemax, Baxi, MORA-TOP, Atem, Electrolux and many others. Both floor-standing and wall models, including gas boilers with cast iron heat exchangers.

Popular models

A gas boiler without electricity is a smart choice for those who don’t want to deal with electronics. The formula “no light - no heating” is unacceptable for many consumers, so non-volatile heating equipment was developed for them. Let's look at the most popular and rated models.

Heating options without the use of electricity and gas

To list all the ways you can heat a country house or cottage, we will assume that electricity is still supplied there. The supplier company has set a small limit on power consumption (3-5 kW), which does not allow electricity to be used as a heat source, but makes it possible to connect heating equipment. When studying each option in detail, we will highlight those that do not require the use of an electrical network.

Houses located on the outskirts are often not gasified

So, if there is no gas and electricity (sufficient power), then heating for the house can be organized in the following ways:

Install a stove or solid fuel boiler connected to a water heating system. Use firewood, coal, fuel briquettes or pellets.
Arrange autonomous heating with liquefied propane from a ramp with cylinders or a gas holder. The heat source will be a conventional gas boiler or convectors that heat the rooms with warm air.
Use diesel fuel and waste oil to generate heat by installing the appropriate equipment.
Draw energy from renewable natural sources, using alternative heating country house solar collectors and a heat pump.

Note. Unfortunately, almost all of these methods become useless when you need to decide how to heat your apartment. We will have to do without liquefied gas and firewood, and liquid fuel is out of the question. There is only one way out - economical heating electricity using infrared heaters or an air-to-air heat pump (in the southern regions an inverter air conditioner will do).

Heating equipment options for an apartment

Let's highlight heat sources that do not require a connection to the house electrical network to operate:

metal and brick wood stoves, fireplaces;
solid fuel boilers, equipped with a mechanical draft regulator and working in conjunction with a gravity (gravity) heating system;
non-volatile floor standing boilers, capable of operating on liquefied gas and connected to a water gravity system with radiators.

To implement other methods, electricity is required, albeit in small quantities. If we do not take into account the various homemade devices, then to burn diesel fuel you need a burner with a pump and a fan powered from the mains. The same is the case with all heat pumps and TT boilers with forced air supply, including pellet ones. Now let’s take a closer look at ways to heat a country house or cottage if there is no gas and the electricity supply is limited.

Solid fuel combustion

One of the most common methods for heating a house without gas is the use of coal, firewood and briquettes compressed from various biomass waste (sawdust, straw, sunflower husks, pine needles, and so on). To burn them and obtain the required amount of heat, a variety of furnaces and boilers are used. The former are designed for direct heating of indoor air, the latter work with water systems - radiators or heated floors.

The easiest option is to install a nice metal stove

Amendment. In a room where a wood or coal stove is located, heat spreads not only by convection from heating the air, but also by infrared radiation emitted by its heated walls.

Heating stoves come in three types: steel, cast iron and brick. The positive aspects of their operation are as follows:

Heating your home with a steel or cast iron stove is the cheapest and easiest way. To install and launch it, it is not necessary to invite specialists; everything can be done with your own hands.
A stationary brick stove is capable of heating several rooms, accumulating a large amount of heat in the thickness of the walls.
Any of these heat sources can be adapted for cooking, drying clothes and shoes.
The design of many stoves includes a water circuit built into the firebox in the form of a tank or coil connected to several radiators located in adjacent rooms. There is a point here: to move the coolant, you need to lay pipes of increased diameter in compliance with the slope (gravity system) or install a circulation pump.
Firewood and coal are the most cheap fuel among all energy carriers, so heating costs are acceptable for most homeowners.
Ovens do not require electricity at all.

A brick stove provides pleasant, healthy warmth, but it’s not easy to build.

Note. A heat source such as a wood fireplace cannot be ruled out. True, it is enough to heat only one room in which it is located.

There were also some negative aspects:

stove heating of a private house without gas means chopping and carrying firewood, loading it and daily cleaning of ash;
for the heater to operate, a chimney with good natural draft is required;
metal stoves are unable to warm up large country cottages; their power is only enough for a country house or 1-2 rooms;
construction brick oven– the pleasure is not cheap, and a place for it must be provided at the stage of design and construction of the building.

It must be taken into account that the brick oven is built on a foundation

Heating stone or wooden house using a water system with a solid fuel boiler is more economical, since the efficiency of these units is higher (75% versus a maximum of 60% for stoves). Due to this, the combustion duration from one fuel load increases, plus the issue of complete heating of the building by heating devices distributed throughout the rooms has been resolved. This creates the possibility of heating large areas of the house in the absence of gas and regulating the intensity of heating of the premises.

TT boiler with mechanical draft regulator in operation

Otherwise, TT boilers inherit the operating features of furnaces. They also need a chimney, periodic cleaning and loading of new portions of firewood and coal. If we compare the cost, then installing a solid fuel boiler together with the system occupies a middle position between buying a metal stove and building a brick one.

Important point. Water heating unit, running on wood or briquettes, can be installed in any habitable home. If there is not enough space, an extension is made to the building where heating equipment is installed.

Separately, it is worth mentioning automatic pellet boilers, which greatly simplify the life of the homeowner, since they need to be cleaned and fuel added once a week. Another thing is the price of equipment and fuel, and also the increased consumption of electricity. In addition to automation, such heat generators use the following electrical installations:

feed auger motor;
electric motor of a fan - blower or smoke exhauster;
heating element used for automatic ignition of pellets.

An automatic pellet or coal boiler is an excellent choice, but it also needs electricity

The listed elements are installed in a pellet burner and in total consume about 500 W from the mains, which is significant for a private home without gas and with a limited limit on the use of electricity. On the other hand, pellet boilers are more efficient and economical than conventional ones (efficiency - 80% versus 75%), and their operation is more comfortable and safe (automation will prevent the unit from boiling). The question is the financial capabilities of the homeowner and the amount of the allocated electrical power limit.

Heating with liquefied gas

Let us immediately make a reservation that in the absence of main gas and electricity, using this fuel is not profitable in all countries former USSR. If Russian prices Although liquefied propane is still used to heat houses, in Ukraine this method is practically not used anywhere, because the fuel is too expensive. You can see the exact breakdown of the cost of heating with different energy carriers in this article.

Any gas heat generator is suitable for working on propane, only a wall-mounted one will have to be connected to the mains

To burn a propane-butane mixture, you will need a regular gas boiler, preferably a non-volatile floor-mounted one, so as not to connect electricity to it. Accordingly, the heating system is water gravity with an open type expansion tank. Gas is supplied to the boiler in two ways - from a ramp with cylinders or from a large underground tank - a gas tank.

When installing and operating the equipment, you will encounter the following points:

Installing a gas train with cylinders (at least 4 pieces are required) will be inexpensive, but the cash costs will have to be offset by labor costs. If you live permanently, you will have to worry about transporting and refilling cylinders much more than if you heat your house with wood.
Installing a gas tank is a costly undertaking. But as a result, you will get autonomous heating without connecting to the gas main.
Liquefied propane is no less efficient and comfortable energy carrier than natural gas, and provides the same advantages during equipment operation.

Methods for supplying liquefied fuel to the heat generator

Advice. It is better to organize heating with cylinders in a small country house, where you visit and live for 2-3 days. Our team will tell you more about all the nuances of using liquefied gas. experienced expert Vladimir Sukhorukov in his video:

Diesel fuel – more disadvantages than advantages

As a rule, burning diesel fuel and used engine oil is carried out in situations where there is nothing else to heat a private house. Sometimes this option is used as a temporary option while the built house is not yet connected to the natural gas main. In this case, you buy a universal gas boiler, temporarily equipped with a diesel burner.

The unpopularity of liquid fuel as an energy carrier for heating private homes is explained by the following reasons:

economical heating of a house with diesel fuel is an unrealistic concept, since the price of fuel is quite high;
diesel burners cost a lot of money and do not function without electricity (we do not take into account any homemade products made by home craftsmen);
liquid fuel means dirt and smell in the boiler room, no matter how hard you try to keep it clean;
Due to the low quality of fuel, the equipment must be serviced frequently, and with the help of qualified personnel.

Heating a country cottage with a Buderus diesel boiler

For reference. If you have a reliable supplier of used oil at a reasonable price, you can try to make your own Babbington burner, saving on the purchase of equipment. Manufacturing instructions are in a separate topic.

So, diesel fuel is far from an economical option, but in some situations it can help out. It is better to organize such heating than to leave the house without heating.

Alternative sources of thermal energy

The first thing that comes to mind when there is neither gas nor electricity in a country cottage is to organize electricity generation in some way. For example, install solar panels and wind farm, capable of meeting all the needs of a private household and serving as a power source for any boiler. But similar project you are unlikely to cope alone due to the decent cost of the equipment and the work required to install it. Unless you manage to involve a dozen more neighbors in the implementation of the project.

Generating free electricity using wind turbines and solar panels will require significant investment

More real option alternative heating - use a heat pump. This product of advanced technologies is widely used in Western Europe and the USA, but in the post-Soviet space it is not available to everyone. The reason is again the high price. The principle of operation of the pump is similar to an air conditioner: thermal energy is extracted in one place (from natural sources) and moved to another (inside a private home).

There are 4 types of heat pumps, which we will indicate along with the cost of the equipment:

"Air - air." Acts exactly like household split system, working for heating. The issue price is from 1800 USD. e., plus installation at least 150 USD. e.
"Air - water." It differs from the previous version in that the thermal energy taken from the outside air is transferred to water into the heating system. The cost of installation of average quality is from 2000 USD. e., installations - about 1700 USD. e.
“Water is water.” These units heat the coolant in the house using energy taken from groundwater or a nearby body of water. More or less reliable equipment will cost you 3000-3300 USD. That is, and the cost of installation depends on the number of wells, the remoteness of the reservoir and other factors.
Geothermal installation "earth - water". Here, an external circuit of pipes delivers heat into the house from deep within the earth, heating the coolant for heating. The most reliable and expensive system, the price starts from 8000 USD. That is, installation - at least 2000 USD. e.

Pipe circuits (on the left) take away the thermal energy of the earth and water, and the installation (on the right) directs it to heat the house

The trick is that these units still need electricity to move thermal energy. To obtain 3-4 kW of heat and use it for heating, you need to spend 1 kW of electricity. When the power limit is limited to 5 kW, then 3 of them can be spent on heating, which will be 12 kW. This is enough for living space 120-160 m², no more.

For reference. When purchasing and operating heat pumps at current prices, we are not talking about any payback for the equipment; subsequent energy savings are taken into account. Our expert will give you more information in his video:

Finally, let’s say a few words about how to heat a private house with solar collectors. These are groups of glass tubes with coolant flowing inside, which are heated by infrared radiation from the sun. Unfortunately, such installations cannot operate independently and here’s why:

at night there is no sun, and there is no heating of the coolant;
in winter, especially in northern regions, too little solar energy is supplied;
To move the coolant you will need a circulation pump powered by electricity.

Connection diagram of solar collectors to the heating system

Due to the above reasons, solar collectors are usually connected by pipes to special fittings buffer capacity, where they give off the resulting heat. But the reservoir is also heated from other sources (boilers, furnaces), so the outlet temperature is enough to heat the house.

conclusions

In current conditions, the best way to fully heat a country house without gas or electricity is to burn solid fuel in boilers or stoves. The main role here is played by the combination of cost heating installations and prices of firewood, coal and other briquettes with pellets. Other options will cost more.

An economically advantageous energy source in our conditions is firewood.

Please note that when choosing thermal power equipment, a simple rule applies: the smaller the initial cash investment, the more troublesome its operation. Any homeowner who wants to organize super-economical heating at a low price must invest more work and time. Conversely, when purchasing and installing expensive heat pumps, the owner of the house is left with one concern - sometimes monitoring the temperature and monitoring the operation of the units.

How do non-volatile floor-mounted gas boilers work?

The operating principle of a non-volatile boiler has several distinctive features, affecting fuel consumption, accuracy of adjustment settings, etc. All components of boiler equipment operate in a mode completely independent of electricity:

Automation - adjustments are made by thermomechanical devices. A thermocouple is used to start and open the gas valve. When heated, a low-grade voltage is generated that is powerful enough to hold the valve stem in the open position.
The heating temperature is controlled by a thermomechanical valve. Inside the regulator is a thin metal rod. When heated, the core heats up and the “needle” closes the gas nozzle.
Heating of the coolant - heat transfer from gas combustion to liquid circulating in the heating system occurs through a heat exchanger. If the boiler operates for heating and hot water, the device has a DHW coil. The pipe is not large diameter, surrounds the primary heat exchanger. Water is heated using a flow method.
Security system - the design is equipped with all kinds of mechanical protection: gas pressure and exhaust smoke valves, various thermostatic controllers.
Burner device - in non-volatile boilers, an open type burner is traditionally installed. In this regard, boiler equipment is called atmospheric, convection, etc.

Types of floor-standing energy-independent boilers

According to their technical characteristics, non-volatile floor-standing boilers are divided by power and number of heat exchangers or circuits. There is a classification according to the main purpose, depending on performance:

Up to 30 kW – domestic boilers.
Up to 100 kW – semi-industrial units.
Over 100 kW – industrial boiler equipment.

Another difference between heat generators is the type of heat exchanger, or more precisely, the material from which it is made. Cast iron boilers are distinguished by their reliability, long service life, and heavy weight. Steel analogs are 1.5-2 times cheaper, but have worse thermal characteristics.

Double-circuit non-volatile

Floor-standing, double-circuit, energy-independent gas boiler, designed for heating and hot water supply. The primary heat exchanger is made of structural or stainless steel. The coil is traditionally made of copper. The latest generation of energy-independent boilers began to use an aluminum alloy tube as a secondary heat exchanger.

Household non-volatile floor-mounted double-circuit gas heating boilers simultaneously heat water and coolant. When heating hot water, the temperature in the heating system decreases. To avoid this situation, some models have a built-in buffer capacity.

Heated water for domestic purposes is stored in a storage tank, like in a thermos. After opening the tap, hot water is supplied to the consumer almost instantly. At the same time, there is no need for the boiler to work for heating.

Single-circuit non-volatile

A floor-standing, non-volatile single-circuit gas heating boiler, unlike analogues with two heat exchangers, is intended exclusively for heating residential premises. This type heating equipment, different maximum performance. If over time there is a need for hot water, an indirect heating boiler is connected to the heating system.

Floor heating single-circuit boilers gas-powered, independent of electricity, are often used to heat residential and industrial facilities. The advantage of the design is greater reliability (compared to double-circuit models), due to the absence of a DHW coil. As practice shows, due to hard water, they quickly fail and require replacement.

How to choose a non-volatile gas boiler

After determining which boiler is better, single or double-circuit, you will need to choose a heating equipment manufacturer. The reliability rating is topped by German technology, but its popularity is reduced by its prohibitively high cost.

Some consumers pay attention to the Italian Baxi SLIM and others. But the leadership in popularity among domestic consumers is occupied by models of boiler equipment produced in the Russian Federation.

It is difficult to list all boiler models. But the most popular (as sales statistics show) are the following nine types of heating equipment: Rostovgazoapparat AOGV, Mimax KSG, Siberia KCHGO, Protherm Volk, Borinskoye AOGV, Termotechnik AOGV and AKGV, Lemax Premium, ROSS AOGV.

Products manufactured in neighboring countries – Ukraine – deserve special attention. Atem Zhytomyr is in demand.

Advantages and disadvantages of a non-volatile gas boiler

Of course, like any other heating equipment, non-volatile models have their pros and cons. Taking into account the pros and cons, you can reduce mistakes when choosing a suitable boiler to a minimum.

When identifying weak points, it is better to focus not only on the characteristics of the manufacturer, but also on real reviews about energy-independent heating boilers.

Positive sides:

Stable operation regardless of external factors.
Simple installation requirements.
Long service life.
The automation does not fail and costs less than a microprocessor controller (installed in volatile equipment).

Disadvantages of boilers are also present:

Higher gas consumption - heating intensity is controlled by measuring the temperature of the coolant. The thermostatic valve has a large error.
The boiler is not designed to operate in conditions low pressure gas Although there are “Kulibins” that offer to reconfigure the automation, in practice this is associated with significant risk.
Installation of a non-volatile boiler, without re-equipment (installation of a pump), is possible only in open systems with natural coolant circulation.

A non-volatile boiler is the best option for heating large areas, especially in areas where there are problems with power supply. The equipment is easy to use, costs less, repairs and adjustments are practically not required. Often, this type equipment used for heating country houses, country houses.

avtonomnoeteplo.ru

Alas, even in the Moscow region, not all cities and towns have high-quality and reliable electricity supply, let alone settlements remote from the center. Voltage in country houses often differs from the nominal voltage by tens of percent; emergency power outages can last for weeks. In such conditions, creating a heating system based on a volatile boiler is very reckless. It makes more sense to use a non-volatile methane boiler that does not consume electricity from the network. What are the features of this technique and what does the market offer?

Application area

Non-volatile boilers for gas fuel used in heating systems with natural or forced circulation of coolant, as well as in DHW systems. Prepared water or, unless prohibited by the manufacturer, household antifreeze such as Hot Blood, Dixis, Warm House-65, Olga can be used as a coolant. Most often, non-volatile gas boilers are used in the residential sector - for heating apartments and country houses permanent residence. Less commonly, they are used for heating small commercial buildings.
All devices that have successfully passed certification in the Russian Federation operate on natural gas with a nominal pressure of 1274 Pa (130 mm water column) in accordance with GOST 5542–87. When replacing nozzles (main burner and igniter), some models can operate on liquefied (cylinder) gas.

The most widespread in the Russian Federation are single-circuit non-volatile boilers designed for heating. Their heating circuit heat exchangers are made of cast iron or steel. Boiler models with cast iron heat exchangers are designed for 20–25 years of operation; the service life of more affordable boilers with steel heat exchangers usually does not exceed 10–15 years.

Apply and dual-circuit models- the presence of a second circuit allows them to be used simultaneously for both heat supply and domestic hot water supply (at a low intensity of water consumption). The secondary circuit coil, as a rule, is made of a copper pipe; its heating occurs due to contact with the coolant.

Injection atmospheric burners are used as burner devices in non-volatile gas boilers.

Safety, reliability, simplicity and ease of operation of non-volatile boilers are largely ensured by the use of modern non-volatile automation units. In boilers with imported (primarily Italian and German) automation, the most significant savings in gas consumption are achieved due to the automatic burner power modulation mode. Boilers with automation made in Russia usually turn out to be the most attractive at the purchase price.

The user adjusts the temperature by setting the boiler water thermostat, based on personal feelings “hotter - colder”. But some models can also be paired with a room thermostat mounted in a control room, which monitors temperature fluctuations and issues commands to reduce or increase the gas supply to the main burner.

In areas where in winter the gas pressure at the entrance to the house decreases significantly, experts strongly recommend the use of non-volatile boilers that can operate stably when the pressure drops (down to 300 Pa and below), without turning off, but only proportionally reducing the heating output. It is unacceptable to leave the device running for a long time without supervision, since in the event of an emergency shutdown of the gas and the boiler stops, the heating system may defrost or other property may be damaged by the cold.

Placement and installation of a non-volatile boiler, as well as gas supply to it is carried out by a specialized construction and installation organization according to a project agreed upon with the operating enterprise/trust gas industry. In this case, the equipment manufacturer’s requirements for air temperature and room ventilation, as well as the requirements for the characteristics of the enclosing structures next to which the boiler is installed, must be strictly observed. Amateur action here is unacceptable, as it is fraught with serious consequences, including the complete destruction of a heated house as a result of a gas explosion!

During the installation of a non-volatile boiler, the closest attention should be paid to chimney. The chimney structure to which the device is connected must comply with SP 42-101–2003 “General provisions for the design and construction of gas distribution systems” and meet the requirements of the “Fire Safety Rules for residential buildings, hotels, dormitories, administrative buildings and individual garages. PPB-08–85" and the requirements of the "Rules for the performance of work and repair of stoves, chimneys and gas ducts."

The chimney, as a rule, should be located in the internal main wall of the building (although variations are possible). Its minimum open cross-section is determined by the boiler manufacturer and in most cases should not be less than ½ × ½ brick. The height of the chimney above the roof of the building depends on the horizontal distance from its axis to the ridge and should be:

♦ at least 0.5 m above the ridge, if the pipe is located at a distance of up to 1.5 meters from the ridge;
♦ not lower than the ridge level, if the pipe is located at a distance from 1.5 to 3 meters from the ridge;
♦ not lower than a line drawn from the ridge downwards at an angle of 10° to the horizontal, if the pipe is located more than 3 meters from the ridge.

It is important that the smoke channel is strictly vertical, smooth, even, without turns or narrowings. Its height from the lower level of the apparatus must be at least 5 meters. Connecting other heating devices to the chimney of a non-volatile boiler is not allowed.

Some models of non-volatile boilers, including parapet models, have a closed combustion chamber and communicate with environment using a horizontal coaxial chimney. It is mounted in through hole in the outer wall and is equipped with a windproof cap. The coaxial chimney also simultaneously discharges flue gases, and combustion air supply.

Using a coaxial chimney allows you to install non-volatile boilers in rooms without a vertical chimney. This significantly expands the scope of application of energy-independent boilers. However, during operation, non-volatile boilers with a coaxial chimney are more likely than devices connected to vertical smoke ducts, are turned off due to gusts of wind blowing out the burner flame, or freezing of the flue (especially models without modulation, operating in the “ON/OFF” mode and allowing condensation to form in the chimney).

Problems often arise due to the destruction by condensation of the masonry of the wall through which the coaxial chimney passes.

When using a heating system with natural coolant circulation the heated coolant from the boiler supply pipe rises through pipes to the upper floor, where it passes through the heating radiators, then falls to the lower floors, where it also releases part of the thermal energy in the radiators, after which it enters the return pipe of the heat generator. Such heating systems are also called gravity.

Let us note that it is necessary to create a heating system with natural circulation of the coolant “with knowledge of the matter”, correctly selecting the diameters of the pipes, maintaining the required angles of inclination in the horizontal sections of their laying. When building a system with natural circulation, it is necessary to take into account the requirements and recommendations of the boiler manufacturer, since the warranty on the device depends on this.

When installing a non-volatile boiler in a heating system with forced circulation of coolant The system configuration, pipe diameters and their inclinations during installation are usually not so critical. But in this case, the pressure in the heating system in operating condition should not exceed the permissible value. To avoid destruction of the boiler heat exchanger, it is necessary to provide a safety valve in the system.

The automatic operation of a non-volatile boiler does not require any externally supplied electricity. In the simplest case, the boiler gas valve is controlled by the voltage generated when the thermocouple is heated in the pilot burner flame, which, in turn, is ignited manually using a piezoelectric element. The voltage across the solenoid gas valve coil keeps it open, allowing gas to flow to the main and pilot burners. When the pilot burner goes out, the gas valve instantly stops the gas supply to the boiler, thus ensuring complete safety in operation.

What does the market offer?

When choosing equipment, the first thing logical to consider is the possibility of using a non-volatile boiler with cast iron heat exchanger. Unlike boilers with steel heat exchangers, where it is necessary to constantly maintain the temperature of the heating water above the dew point, when operating cast iron boilers, even at a heating water temperature of about 30 °C, fatal damage to the heat exchangers by low-temperature corrosion does not occur.

Most models equipped with a cast iron heat exchanger are supplied to Russia from EU countries. European technology brands- these are Alphatherm Delta (Hungary), Alphatherm Beta (Slovakia), Attack (Slovakia), Beretta (Italy), Electrolux (Sweden), Protherm (Slovakia), Viadrus (Czech Republic), Fondital (Italy).

Thus, floor-standing energy-independent gas boilers Electrolux FSB-P are supplied in a power range from 14 to 60 kW. This is a fairly new range of highly efficient floor standing boilers with a high performance gray lamellar cast iron sectional heat exchanger.

Thanks to the application new technology DROP STOP heat exchanger of the Electrolux FSB-P boiler is resistant to hydraulic shocks and thermal deformations.

The use of NANO FLAME technology, even at a gas pressure of 350 Pa, ensures stable ignition and long-lasting trouble-free operation atmospheric gas burner. This technology allows the boiler to continue to operate even when the pressure in the main line drops to 220 Pa.

The burner of the Electrolux FSB-P boiler is protected from burnout by preventing the surface of its flame pipes from heating to critical temperatures.

Manufacturers of non-volatile gas boilers with cast iron heat exchangers from Russia and the CIS countries often create devices using imported components, which allows them to obtain equipment of fairly high quality, the price of which is approximately 10–15% lower than that of imported products with similar characteristics.

As an example, we can cite the line of cast iron non-volatile boilers “Titan N” from CJSC Gaztekhprom (Ryazan) with a nominal heating output of 25 to 60 kW, which are equipped with gas valves and SIT control units (Italy) with a full safety group that corresponds to all domestic and European requirements.

Titan boilers are equipped with atmospheric burners from POLIDORO (Italy) with stainless steel fire tubes.

Here we will mention the Taganrog boilers "Lemax Leader GGU-ch" with a power from 19 to 55 kW, equipped with a VIADRUS heat exchanger (Czech Republic) made of high-quality gray cast iron 4 mm thick, as well as Siberia KChGO gas boilers with an imported cast iron heat exchanger, burner and automation unit, manufactured in Russia at the enterprise of CJSC Rostovgazoapparat in the city of Rostov-on-Don.

Separately, it is worth mentioning the KCHG cast iron floor-standing gas boilers from Servicegaz LLC, Ulyanovsk. These boilers use a highly efficient cast iron heat exchanger with a needle convective heating surface, main burners made of heat-resistant stainless steel with slotted grooves. Gas pressure stabilizer built into gas block, ensures uniform combustion of the gas-air mixture on the main burners with constant heating output, regardless of the gas pressure in the network, without requiring adjustment.

The KChM-5-k boilers from OJSC Kirov Plant, equipped with non-volatile automation SABC (execution 17; 23; 36). Their undeniable advantage is their versatility - a boiler, originally designed to operate on gaseous fuel, can subsequently be easily converted to operate on solid or diesel fuel and even waste oil.

The main advantages of gas floor-standing energy-independent boilers with steel heat exchangers We can attribute their low mass, which is important when installing equipment in houses with “weak” walls and ceilings, increased resistance to water hammer and thermal loads, low inertia (devices quickly respond to changes in heat demand) and are even more affordable than boilers with cast iron heat exchangers, price.

Among the imported equipment, we note single-circuit energy-independent floor-standing gas boilers of the Dakon P lux series, maximum power which is in the range of 18–50 kW. The devices are designed for heating various rooms and can be integrated into both natural and forced circulation systems. The internal space of the steel heat exchanger of P lux boilers is formed by sections with nested economizers for the fullest use of the thermal energy of combustion products.

DAKON P lux boilers are equipped with HONEYWELL CVI automatic equipment and are manufactured in two modifications - “ON/OFF” (modification Z) and with two-stage power control “HIGH-LOW” (modification HL). One of the functions of the P lux boiler is quick stop of operation when used draft regulator, it significantly increases its safe operation.

Interesting models of non-volatile floor-standing boilers “Wolf KSO”, equipped with a steel heat exchanger, are presented in the Russian Federation by the company Protherm. The boilers are assembled at the plant in Taganrog under the close attention of Protherm employees, which, according to the manufacturer, guarantees high quality and reliability. It is worth paying attention to AOGV - Beretta with a heating capacity of 11 and 17 kW, which were developed in accordance with the requirements of GOST 20219 “Domestic gas heating devices with a water circuit.”

Russia has a traditionally strong position domestic producers non-volatile floor-standing boilers with steel heat exchangers.

For example, the Russian non-volatile heating devices of the Zhukovsky Machine-Building Plant are well known - single- and double-circuit heat generators of the Economy, Universal and Comfort series with a heating capacity of 11 to 63 kW. The devices are reliable and durable. The use of a steel heat exchanger with turbulators, a modern atmospheric slot burner and high-quality automation units in the devices, according to plant representatives, made it possible to improve environmental parameters and increase their real efficiency.

All non-volatile boilers of the Zhukovsky Machine-Building Plant are certified by the State Standard of Russia, have a sanitary-epidemiological conclusion and a decision of the State Technical Supervision Authority of Russia for production and use.

In the city of Borino, Lipetsk region, a household appliances plant gas equipment Since 1997, JSC Borinskoye has been producing non-volatile boilers equipped with a steel heat exchanger with a capacity of 12.5, 25, 31.5, 40, 50, 63, 80 and 100 kW. The plant provides warranty and post-warranty service for its equipment, “wide geography” service centers and a completely reasonable price both for the boiler itself and for its maintenance and repair.

Siberia heating equipment produced by Rostovgazoapparat CJSC is in demand among buyers. In terms of thermal characteristics and design, these non-volatile boilers are not inferior to many foreign analogues. Siberia boilers use a heat exchanger made of carbon structural steel with a developed heat exchange area, Eurosit automation, and a WORGAS burner. The boilers are resistant to large differences in gas pressure and have high efficiency. Basalt fiber is used for thermal insulation of the boiler.

A variety of non-volatile boilers with a steel heat exchanger are considered to be single-circuit and double-circuit parapet boilers. They are equipped with a closed combustion chamber and connected to a horizontal coaxial chimney. The boiler is mounted on the floor, near the outer wall, in which a hole (about 300 mm in diameter) is previously made for the release of a coaxial chimney.

Large quantities of parapet boilers are supplied to the Russian Federation from Ukraine. As an example, we can mention DANI parapet AKGV 7.4-U-S (new) - a double-circuit parapet gas boiler with a sealed combustion chamber with exhaust of combustion products through a horizontal chimney. This model is an updated series of Dani parapet boilers with the ability to connect to the heating system on both the right and left sides. Supplied with coaxial chimney kit.

We also note the Ukrainian parapet boilers “ThermoBar KS-GS-7.0 S” (JSC “Barsky Machinery Plant”), characterized by a long service life and an efficiency of at least 90%. Operating pressure boilers up to 2 kgf/cm² allows them to work with natural and forced coolant circulation. The boilers are equipped with a multi-section atmospheric stacked burner made of stainless steel.

Parapet boilers from the Impulse and BeleTo brands are free from many of the disadvantages of parapet boilers from other manufacturers. Their heat exchangers are made of anti-corrosion steel with a thickness of 3–4 mm, which significantly increases reliability and service life (in some other parapet boilers the heat exchanger is made of steel with a thickness of only 0.8–1.2 mm).

The BeleTo boiler can take combustion air from both outside and indoors. When taken from the room, air is sucked into the boiler body from above, and not from below, which prevents the burner from clogging. Thanks to the two-section burner, the Impulse boiler has a power control range from 20 to 100%, and the BeleTo 40 boiler -100%, which is important for the Russian winter with its wide range of outside air temperatures during the heating period.

Boiler Protherm 40 TLO (35 kW)

Heating systems independent of electricity are installed in areas and settlements where there are serious problems with energy supply. Installation of non-volatile gas boiler is the only way to save comfortable temperature in room. These devices are used in gravity heating systems, where the coolant circulates through pipes under the influence of gravity and thermal expansion of water. Equipment manufacturers offer single- and double-circuit versions of such devices.

Operating principle of the boiler

The equipment does not require connection to a power source. Structurally, it contains a thermogenerator. When gas is supplied to the combustion chamber using piezo ignition (triggered by pressing a button), the pilot burner ignites. It burns constantly, providing ignition of the main heat source if necessary. It, in fact, heats the water in the heating system.

The coolant heated to a certain temperature acts on the thermostat, which turns off the gas supply to the main fireplace. By giving off heat, the water cools and activates the gas supply mechanism. The gas supply is resumed, and it ignites from the “standby” burner.

Functional benefits

The fact that a non-volatile gas boiler can operate without electricity is not the only advantage of the device. The design of its chimney also ensures the safe operation of such equipment. The channels provide installation of sensors that determine the level of traction. If it decreases or if reverse flow occurs, the gas supply to the combustion chamber automatically stops.

Constructive and operational features provide other advantages of such boilers:

automatic flame intensity control;
presence of piezo ignition;
long service life of the heat exchanger;
maintaining functionality even with a significant decrease in gas pressure in the system.

Many models are equipped with a remote control, which makes their use even more convenient.

Installation Requirements

Double-circuit gas boiler

Single- and double-circuit non-volatile heating boilers are installed in accordance with the requirements ensuring natural circulation coolant.

These include:

Mandatory compliance with the slopes of pipelines in which water circulates.
Using a large diameter pipe to reduce resistance along the coolant path.
Additional installation into the system expansion tank, where excess heated water will fall.

In addition, it is necessary to strictly adhere to the standards for the installation of gas equipment. In particular, this applies to the installation of ventilation and exhaust gas removal systems.

Important! In case of violation of requirements and standards state standards There may be an accumulation of carbon monoxide in the room. This is dangerous not only for health, but also for the lives of all family members.

Involving persons who are not authorized for this type of work in the installation of the system is strictly prohibited. All work is carried out by specialists who have passed the appropriate accreditation.

Boiler model options

A non-volatile floor-standing boiler is more popular among consumers than its wall-mounted counterpart. It is distinguished by its simplicity of design and reliable operation. Manufacturers offer equipment of different capacities, which allows you to choose the best option for a small dacha and for apartments with an area of over 200 square meters.

Floor standing gas boiler

Install non-volatile floor-standing boilers in separate room, where you can easily arrange good supply ventilation. The open combustion chamber takes air from the room, and exhaust gases are discharged through the chimney.

If it is not possible to allocate a separate room or build a furnace room, then you should purchase a wall-mounted analogue. Relatively recently, suppliers began to offer energy-independent gas wall-mounted boilers. They do not take up much space, can be equipped with coaxial chimneys and have all the advantages of floor-standing analogues.

Modern models no longer require a gravity heating system. They are great even for hidden heating mains. In this case, a circulation pump should be installed separately.

Important! The pump must be installed on the return line and pump water into the boiler, and not vice versa. This will ensure efficient loading of the heating device and prevent it from operating with a small amount of water in the heat exchanger.

The pump is mounted through a bypass of a suitable diameter. It is advisable to install 2 taps at the inlet and outlet of the bypass, and also put a tap on the main line (it closes when the forced circulation). In this case, it is possible to replace or repair the injection device without draining the water from the entire system. And to extend the life of the pump, you should install a strainer in front of it.

As you can see, different options for gas boilers can be an excellent alternative to electric ones in cases where there are some problems with the power supply. They are simple in design, easy to use and quite affordable.

Non-volatile floor-standing gas boilers are heating equipment that can operate without being connected to a source of electricity. They do not require an electrical network, which makes them possible to operate in buildings without electrification. They are also suitable for heating households in rural areas, where power outages are frequent due to wear and tear. electrical networks.

Advantages and features of energy-independent boilers:

Provide heat in the absence of electricity;
Simple design without unnecessary electronics;
Fully automatic operation;
There are no extra costs for electricity.

Non-volatile boilers are used in many Russian households. They are characterized by stable operation and do not require excessively frequent maintenance. To ignite gas, they use ignition burners, ignited using a piezo ignition system. The boilers automatically maintain a certain coolant temperature, creating a comfortable atmosphere.

Non-volatile boilers are divided into single-circuit and double-circuit. Single-circuit models are simple; they are designed only for heating rooms. Their double-circuit analogues are equipped with additional heat exchangers for preparing hot water. This eliminates the need for consumers to purchase water heaters. There is also a division into models with open and closed combustion chambers - the latter require coaxial chimneys, providing air intake and removal of combustion products at the same time. Models with open chambers are connected to traditional chimneys and require an inflow fresh air into the room.

Floor-standing, non-volatile gas boilers are available for sale in many models from Russian and foreign manufacturers. When choosing heating equipment, focus on the number of circuits, thermal power and the performance of the DHW circuit (if available), as well as the type of heat exchanger (steel or cast iron). Non-volatile gas boilers are reliable and elegant solution for those who want to decouple heating from electrical networks and ensure its stability. Many models of these boilers can operate on liquefied gas, which makes it possible to heat buildings built far from electrical networks and gas mains.

You can buy a floor-standing gas non-volatile boiler in the Teplodvor online store. We have prepared a large catalog for our customers, which presents heating equipment from well-known brands. Delivery services are provided - throughout Moscow, the Moscow region and throughout Russia.

Heating systems have changed a lot since their inception. The initial concept implied the obligatory provision of communications and the immobility of the structure. However, they can be installed anywhere, separate from power lines. At the moment, such devices are not much more expensive than traditional ones, because demand allows us to produce goods at a reasonable price that will be affordable to consumers of any income.

How does an autonomous gas boiler work?

The device is connected to the gas channel and water supply system. Depending on the device, water flows through the system one or more times.

Boilers of more complex design are equipped sensors and automatic protection mechanisms from overheating and emergency situations.

Such equipment includes at least two. When turned on, the piezoelement ignites the pilot burner, and from it the ignition is transmitted to the main burner.

The main burner warms up the heat exchanger and then the device goes into standby and heat retention mode. When lower temperatures are reached, the process is repeated.

Types of non-volatile boilers

Single-circuit and double-circuit

Passing through the heating element, the temperature of the water rises. This is how it is designed ( circuit– the path along which water moves). works on a similar principle, except that the heated water passes through a system of sensors that measure the temperature and send information to the control panel.

If the temperature exceeds the norm, the gas pressure decreases to balance it. If the temperature readings turn out to be critical, the system will turn off the boiler for a while to avoid overheating, and then turn it on again.

Floor and wall

Certain systems are too heavy or bulky to be placed on walls, so install them

Another reason is portable pump that can vibrate, thereby weakening the point of contact with the wall. As a rule, only large boilers for large-scale enterprises and warehouses.

Reasons for choosing a boiler without electricity

Advantages of the equipment

relatively small dimensions;
a light weight;
ease of use;
no problems with repairs and finding parts;
affordable price.

Flaws

slow heating;
need to replace the power source;
low power(small heating area).

How to choose the right model?

First you need to decide on purpose of purchase. If the boiler is purchased for personal home use , then you should not buy expensive large devices. For heating an apartment or a small private house, a medium-sized product is suitable price category, power 10-15 kW.
Then you need estimate the budget, which will include purchase, delivery, installation. The last point is often not taken into account in calculations, but in vain, because when purchasing an expensive boiler, you need to connect it correctly, otherwise breakdown is inevitable.
pay attention to reviews on the Internet to find out how easy the selected boiler is to operate and how difficult it is to find spare parts.
Consult contact your equipment supplier regarding this issue. Almost all modern companies offer services of a technician visiting the installation site. The specialist will assess the area and furnishings and offer several options for the buyer.

Features of documentation and installation

Before you begin installing gas heating boilers, you need to obtain documents and permission, and prepare the installation site.

Before certification of the gas equipment installation project, it is necessary to resolve all technical issues with the authorities gas service.
Installation work can be carried out only a certified specialist with a license and permission to provide services.
After installing a gas boiler, it is imperative obtain approval from a gas service representative that the boiler complies with norms and standards current legislation of the Russian Federation. This item required, because the boiler belongs to the equipment with an increased level of potential danger and may lead to an accident.
Seal all components of the heating system.
Before installing the gas valve, you need to install And .

The boiler room can be located on any floor multi-storey building, even on ground floor, in the attic or basement. Exception - living rooms. Concerning toilet and bathroom- they have a boiler room better not to do it.

It is imperative to ensure that the room in which the boiler room will be located and the gas boiler itself satisfied all fire safety standards and regulations.

To calculate the volume of the room for installing a gas boiler, it is necessary take into account the total thermal power both the unit itself and the water heating elements - flow-through and capacitive.

It must be recalled that installation without permission is violation of SNiP 2.04.08-87. Fine can range from 1,000 rubles to 15,000 for individuals, from 25,000 rubles to 120,000 rubles for legal entities.

If an illegally installed boiler caused an accident or caused damage, citizen threatens criminal penalty.

REFERENCE! Please note that in the technical passport for a gas boiler, the room for installing the boiler must appear as a boiler room or furnace room. To calculate the volume of the boiler room, you must use the data given in the table below.

Required documents

Calculation of fuel consumption. To the gas service need to be sent calculations of gas consumption per month and per year. If the civil service approves the person’s request, he will be given documents, technical condition, and within 1-2 weeks all work will be completed. If the house already has a gas pipeline, a meter will simply be installed on it. Government organizations also do this.
Technical specifications issued on the basis of a heating appliance installation project. This includes not only installation of equipment, but also pad gas pipes from the utility point to the boiler room.
The project will be approved gas service employees. In addition to the project itself, you must provide technical passport and certificate of this device, operating instructions, expert’s statement that the equipment is standardized.
A project that has received approval can be carried out.

Installation rules

Mandatory installation requirements:

REFERENCE! This point is not regulated by law and installation standards, but the boiler cannot be placed near a stove, boiler or other hot objects, since the total power of the temperature field between them will increase, and automatic control systems will lower the temperature to avoid breakdown. In this case, the sensors will show the norm, and the temperature in the room will be noticeably lower than stated.

Install such equipment on your own - not the best best idea , since in case of any breakdown you will have to pay a fine for violating the rules. Such equipment can only be installed gas workers, which means the responsibility also falls on their shoulders. In addition, do-it-yourself installation involves falsifying documents, because in the project protocol you will need to indicate the installer, and this can only be a gas service employee. If you have all the necessary skills and documents and still want install the boiler yourself,

It’s better to do it yourself diagnostics - visual inspection , checking readings from sensors, measuring water temperature, inspecting ventilation, etc.

An autonomous boiler is an excellent heating solution small house or office space on several floors. Operation, monitoring and diagnostics present absolutely no problems, and the rules and requirements for installation are very flexible.

It is difficult to find a room that would not be suitable for installing a boiler, and if there is one, putting it in order is a matter of a couple of days. In order not to rack your brain with calculations - contact your service provider, who will calculate the cost of installation and equipment for you free of charge.
