Which is cheaper, a stove or a boiler? Boiler or stove - how to heat the house? Firewood made from softwood

For small country house always, it seems to me, will remain topical issue What to choose for heating - a boiler or a stove.

When the house is big, from 100-120 square meters, . Especially if the house is built on 2 floors and divided by partitions into separate rooms.

In this case, to heat the house, it is reasonable to install a boiler with a liquid heating system or heat the house with any types of convectors - gas or electric.

If there is a gas main running along the border of the property, to which you can connect for little money, then the issue of installing the boiler generally becomes resolved and is not subject to serious discussion.

The kind of convenience it offers gas heating, will not give you any other type of heating except electric.

However, with current tariffs for electricity or convectors, only people with a constant good income can afford them.

But in the case when the house has a small total area, from 40 to 100 square meters, the question of what to supply for heating it remains open.

Heating a house with a stove - pros and cons

In the case where the house is an open space, not divided by partitions into separate rooms, you can and should consider heating the house with a stove - brick or metal.

• A lot of good and bad has been written about brick ovens, which have served our ancestors for hundreds of years. The main advantage of brick stoves is relatively uniform heat transfer and “soft” heat.
• The main advantage of metal stoves, steel and cast iron, is their cost compared to real masonry brick oven and installation speed.

Suffice it to say that a cast iron or metal stove can be started in just one day - from purchase in the morning and evening of the same day.

You buy a ready-made heating unit made of steel or cast iron, deliver it, install the base, provide fire protection walls and ceilings, install steel chimney. You can light the stove.

In the case where you use a ceramic chimney, it will last a little longer.

The main disadvantage of a metal stove is its large fire danger, the walls of such a furnace become very hot, surrounding objects or walls made of combustible materials can ignite if the required distances and materials for protecting the walls and penetration of the floors are violated.

The main disadvantage of a brick stove is that it is extremely difficult in our time to find a competent stove maker who will build you a really good brick stove.

However, the brick oven, and metal stoves and fireplaces have one big common advantage - they heat the air in the house and do not require the installation of a heating system. That is, when installing a brick or metal stove, you will not need pipes, radiators, shut-off valves, a safety group and an expansion tank.

For a small country house, this will be a defining moment for many fellow citizens.

You also won’t have to worry about any problems in the cold when you’re not at home.

Heating a house with a boiler - pros and cons

If you have the opportunity to install a gas, electric, pellet or diesel boiler, then you can set up a home heating system with automatic temperature control. Not a single furnace is able to operate in a fully automatic mode, unlike the above types of boilers.

If you permanently live in your country house, then the boiler will allow you to start the heating system in the fall and turn it off in the spring. And in the interval between starting and stopping the CO, it is minimal to control it. Electric, gas and diesel boilers will provide you with this mode of operation.

In the case of a pellet boiler, you will have to load the bunker with fuel at a frequency from once a day to once a month, depending on the volume of the bunker and the degree of automation of the boiler. Pellet boilers, equipped with automatic ash removal, will allow you to make “trips” to the boiler room no more than once a month.

What to choose for heating your home – a boiler or a stove?

If you visit your country house on short visits, on weekends or during vacations, then you don’t have much of an alternative - you’ll have to install . Because in the case of a boiler, you will have to constantly monitor the performance of the heating system and ensure that the CO does not freeze.

You can supplement the air heating system at home, which is any stove, with other heat generators air heating– electric or gas convectors.

For installation electric convectors you will need dedicated electricity capacity in a decent amount. And gas convectors can be powered both from main gas and from bottled liquefied gas.

If you permanently live outside the city in your home, then installing a liquid heating system is the most reasonable alternative to stove heating.

Vladimir Tolbukhin, 2015.

Choice heating equipment- Very difficult task. The main difficulty is that people do not even understand the terminology well. For example, many do not understand the difference between a boiler and a stove, while others understand, but do not know how to choose a boiler or oven For his private house or dachas.

What is a stove?

The very first thing that comes to mind when you hear the word “stove” is a Russian brick stove with warm walls, a cooking chamber and a stove bench. It warms you up, cooks dinner, and you can sleep on it. In the old days there were only such stoves. Additionally, they had different shelves and niches where you could dry anything: from crackers to felt boots.

Due to its massiveness and brick walls A Russian stove accumulates and slowly releases heat. If the house is well insulated, then one kindling is enough to keep the interior warm all day long. comfortable temperature. But that's where the benefits end.

Disadvantages of a brick stove:

But it is too early to conclude that only decision Problems suburban heating V modern conditions- This boiler installation in a private house . There are other stoves - metal ones; according to some criteria they are better than a brick one, but according to others they are worse.

Metal stove compared to brick:

• more compact;
• easier to install - no stove maker or foundation required;
• can operate in long-burning mode.

However, metal stoves are not able to accumulate heat; they cool down and stop heating as soon as the wood in them burns out. And they are not so colorful and comfortable that they should be placed in the middle of the house, like a Russian stove.

What is a boiler?

If the stove heats the air around itself, the boiler heats the coolant. This is the fundamental difference. Typically the coolant is water. A water jacket is built into the firebox, and there is an inlet and outlet for connecting the pipe system that is laid throughout the house. Water is heated in the firebox, begins to circulate through pipes, radiators and heats the house.

Thus, the boiler, especially if there is a pump, can be installed in any room and place, even in a neighboring barn or garage. Boilers are often installed in basements. They do not need a foundation; it is enough to assemble the chimney correctly.

Are common installation requirements solid fuel boiler in a private house the most feasible: room area - at least 7 m², distance to walls - 0.5 m, good ventilation, base made of non-flammable material, sheet of iron in front of the firebox. But with “registration” in your house gas boiler may have problems.

Installing a gas boiler in a private house is not always possible even if there is a gas pipeline

A gas boiler is the most trouble-free and economical heating equipment, but only if gas has already been supplied to the house and the boiler is already installed. If you want to connect to a gas pipeline running nearby, you will encounter many problems: how to obtain permission, draw up technical specifications and a project, and most importantly, the price of connection causes mute surprise and a decision to abandon such pleasure.

Therefore, even if a gas pipeline runs right through your site, do not rush to buy a gas boiler, first find out how realistic it is to connect to this “golden” pipe.

An electric boiler is also not available to everyone due to its high cost.

Installation electrical boiler in a private house Unlike gas, it does not depend on anyone but you. No permits or other documents are needed; initially, the money will be spent only on the purchase of the boiler itself. But only wealthy people can afford to heat a house with electricity, and prosperity is not always a constant phenomenon. Electricity is expensive, and in the private sector, tariffs are twice as high. It is not wise to spend your entire salary or pension on heating.

For the above reasons, today solid fuel boilers and stoves are widely used throughout Russia.

What's better: installation of a boiler in a private house or ovens?

From the definitions of these two different units we can draw the following conclusions:

The last option (stove plus boiler) is the most reliable for any private home, especially if it is large. After all, a supply of heat never hurts. Some people install two boilers in their house, running on different fuels: when one runs out, the heating system is switched to another.

How to choose a boiler for a private home?

Despite the differences between a boiler and a furnace, furnaces are selected according to approximately the same criteria. Boiler installation requirements and ovens in a private house also identical, aimed at ensuring fire safety. And one more nuance, no matter how progressive the design of your boiler or furnace is, good warmth will not happen if you use bad fuel.

In this article we will talk about what is best to use for heating your home. : boiler or Which of these devices can provide its complete autonomy. It's the latter is of great importance because:

the operation of external heating sources is very often unstable and unreliable;

The power of external heating sources is sometimes not enough for the tasks modern house;

the cost of connecting to electricity and gas networks is growing every day.

In addition, these are capital investments, the effectiveness of which requires thoughtful calculation and comparison. Considering all of the above, one can understand why heating equipment running on solid fuel is becoming increasingly widespread. That is why both boilers and furnaces are being improved and their capabilities are expanding. But to receive maximum benefit when using them, it is important to understand them accurately intended use, principles of selection and maintenance. Let's consider each type of heating equipment separately.

Bake – This is a heating device in which the heat released during the combustion of fuel (wood or coal) is transferred through the walls of the chimney to the walls of the building and then warms the air in the surrounding rooms. Theoretically, this heating device can heat a room of any size (remember, for example, huge halls Louvre or Winter Palace, which long years heated by stoves), but it required great amount fuel and the constant work of trained personnel, as well as the allocation of large basement or semi-basement rooms for technical purposes and the installation of branched chimneys.

That's why in practice, stoves are intended for high-quality and sustainable heating of the house area 40-70 sq.m.. However, among these devices there are pleasant exceptions. – ovens Buleryan and Kuznetsova.

Stove Buleryan – it is an all-metal structure with numerous outlet pipes . At its core, it is a “potbelly stove”, only when burning fuel it does not become red-hot and does not burn the surrounding air, but provides direct heating. Therefore, this stove can be used for full heating small house. However, it is not able to accumulate heat and has low efficiency.

Kuznetsov furnace made on the basis of the traditional one, but it uses a special mechanism for circulating hot air (it moves under the influence of its own gravity) . Due to constant turbulence and increased pressure, the perception of heat by the walls of the structure increases, which leads to a decrease in fuel consumption. However, no matter how well thought out this stove is, it requires adaptation to individual objects.

It is precisely due to the peculiarities of their designs Buleryan and Kuznetsova furnaces can heat houses area up to 100-150 sq.m.. But in houses with several floors large area and large flights of stairs, stoves, like fireplaces, will primarily perform an aesthetic function.

Boiler – This is a set of equipment placed in a single housing designed to transfer energy obtained by burning fuel to a coolant (usually water) . As solid fuel are used firewood, hard or brown coal, pellets, etc.. Unlike a stove, a solid fuel boiler can heat houses of any size. You just need to choose the right equipment with the required performance. For an approximate calculation, you can use the ratio 1-1.25 kW for every 10 sq.m building. For example, for heating a house area 150-170 sq.m you will need a boiler power 20 kW. This power will be quite enough to maintain the required level of heat in the house even on the coldest days. Of course, for a more accurate calculation it is necessary to take into account the type of materials, the thickness and weight of walls and ceilings, the presence and location of windows, etc.

From all of the above it is clear that In terms of heat transfer and cost, solid fuel boilers are preferable to stoves for heating large houses.

Now let's compare construction features both heating devices.

It will be difficult to build a stove in an existing building, but at the stage of its construction it can be built on any floor. Therefore, it is best if you think about heating your home at the design stage. Because (as the famous saying goes: “you need to dance from the stove”) the entire layout of the house will have to be formed around it. The stove should be placed so that all or at least most rooms have access to it. common wall or an angle, that is, they formed a thermal contour. The exception to this rule is stairs, so winter period it will be cold on it. It is also necessary to provide for the possibility of outlet through the floors and roof. chimney pipe.

And here there are no requirements for placing a solid fuel boiler in the house . It can be installed in a house of any shape and layout. It is only necessary to provide separate room (boiler room) to place it, ceiling height which should not contain less 2.5 m, A daylight should be calculated based on the ratio 0.03 sq.m/cub.m. Also in this room it is necessary presence of air ventilation, and when placing the boiler room in the basement or ground floor required separate exit to the outside. The house as a whole needs an electrical grounding circuit. Well, of course, in this case you can’t do without a device chimney. Its diameter must be calculated by a specialist. However, it must be remembered that this value must be taken with a small margin. A solid fuel boiler can easily be installed in an already existing house. True, in this case you will have to use external structure chimney, which will need to be insulated.

It is also necessary to take into account when choosing heating device, What It is now very difficult to find a highly qualified specialist to build a furnace . But many specialized companies install solid fuel boilers.

Thus, the boiler won an unconditional victory over the furnace here too.

In the next part of the article we will discuss and compare the operating parameters of furnaces and boilers, as well as their maintenance and durability.

What needs to be built to heat Vacation home? “Oven” – the older generation will answer. "Boiler!" - modern homeowners will object. Why have heating boilers almost everywhere replaced stoves, which are used only as an element of the interior? Let us formulate several points, and we will try to be concise. So, buying a boiler is...

Easier. Installing a stove in a house that has already been designed and practically built is very troublesome, but a boiler can be installed at almost any stage of construction or renovation. There are also not very many requirements for the boiler room: ceilings at least 2.5 meters high, a sufficient level of lighting, the presence of ventilation and a chimney... The installation of all this can be done perfectly by a competent boiler installation specialist, who, by the way, is now much easier to find than a stove maker .

More economical. Solid fuel boilers heating systems consume at least 25 (or even 50) percent less fuel than stoves, and the use of gas stoves is even more profitable. Thanks to a well-designed air supply system and an optimally selected size of the firebox, the boiler needs to be loaded every few hours, while firewood needs to be added to the stove almost every half hour.

More versatile. Double-circuit boilers They work both to maintain heat in the house and to heat water for bathing, washing, and washing dishes. Moreover, one does not interfere with the other at all: even if the boiler is actively working only to heat water (which in fact practically never happens), the temperature in the room will not drop.

More convenient for owners big houses. Practice shows that conventional ovens They are not always able to cope with heating cottages with an area of ​​more than 70 square meters. If you need to provide heat, for example, two-storey house, you are unlikely to be able to do this with one oven. The boiler perfectly distributes heat throughout the house from one room, regardless of the layout. Formally, the efficiency of a furnace can significantly exceed the corresponding indicator of the boiler, but when choosing a heat source you cannot rely only on this indicator.

Stove heating has not yet said its last word: new models are constantly appearing on the market, which are presented as more advanced devices. However, stoves are gradually giving way to heating boilers, and the day is not far off when the presence of a stove in a house will be perceived solely as antique styling.

When contacting a company to repair your home, you should protect yourself from all sides. Who said that calling a qualified craftsman will guarantee a luxurious repair? After all, you don’t even know this person, so believing only words will be the height of stupidity. After the main issues have been resolved verbally, why not create an agreement for this type services?...

Every apartment has water supply, which makes our life much easier. But the consequences may be different, since leaks often occur. In such situations, there is a need to pay compensation to your dear neighbors. To avoid such problems, it is better to prepare in advance and do complete waterproofing flooring in a damp room. In order to provide protection...

Huge volumes of work with petroleum products give the name to a whole class of equipment designed specifically for working with these substances. A significant amount of special equipment for these purposes is designed taking into account the specific density, viscosity and aggressiveness of the environment. Product designs may vary. Centrifugal, screw, gear. IN various options executions for highly specialized purposes. The gear type is designed for pumping viscous fractions....

WHAT IS BETTER OVEN OR BOILER?

What to choose for heating your home– fold bake or install boiler? Laying a furnace will not cost much less than installing a boiler. It is necessary to install a foundation under the stove - which will involve dismantling part of the floor and walls of the House. The stove will heat the air around it well, but it will be cold near the walls and windows because air draft occurs- from the walls of the room into the interior of the stove - to maintain combustion and further into the chimney, along with combustion products. The oven gives most heat with its walls, which can get quite hot - which can be dangerous if children grab onto it. The efficiency of the stove is no more than 30%, while any Boiler has an efficiency of 70%. Your benefit lies in significant savings in wood or coal.

Boiler and boiler indirect heating

Boiler installation And radiators (heated floor) will require laying pipes, installing collectors and a water distribution system to the heating circuits. As a result, you will receive a heating system in which all rooms in your house will be warm, and, at the same time, you can safely touch the radiator with your hand and pleasantly walk on the heated floor.

This is explained by the fact that the boiler heats up not the air around itself like a furnace, but the coolant (water or antifreeze) that flows through pipes to radiators that are installed under windows or in warm water floor. Next, radiators or heated floors give off heat to the air, which circulates and heats the room. Another undeniable advantage of any boiler is its - you set the temperature, for example, 25 degrees Celsius and the system maintains it itself. That is, you don’t need to get up at 2 o’clock at night and at 8 am on a day off to “throw some wood in the stove.” Another boiler advantage– the system may be indirect heating boiler installed, which will have a reserve and give hot water directly into the kitchen faucet or shower at any time, meaning there is no need to heat pots of water on the stove to wash dishes.

heating solid fuel boiler and radiators

Undoubtedly advantages of the oven will be her ability “ work without electricity“, the ability to drown. Stove heating is well suited for those who have a house with an area of ​​up to 70 m2, live in the house on short visits - 1-2 days a week and are ready to throw firewood into the firebox 3-4 times during the day (get up a couple of times at night and come up the same number of times to the stove during the day).

In front of everyone advantages of stove heating requires increased attention to security. First of all, the threat fire and threat carbon monoxide poisoning that lead to terrible tragedies.
Carbon monoxide (CO, carbon monoxide) is a poisonous gas without color, taste or smell, which makes it especially dangerous. Carbon monoxide appears in the furnace due toincomplete combustion of wood due to untimely closing of the stove valve. Limited access of fresh air to the firebox, poor draft and a clogged chimney contribute to the formation of CO. It is very difficult to recognize the initial symptoms of poisoning. Carbon monoxide causes severe drowsiness, confusion, hallucinations, even fainting and coma, and possible cardiac arrest. Help with poisoning is Fresh air and an emergency doctor.
The most dangerous thing is to think that all tragedies happen somewhere and to someone, but nothing like that can happen to us.
At stove heating You must always remember to close the furnace valve in a timely manner. Before this, be sure to stir the coals with a poker - there may still be some leftovers there.
charred firebrands that need to be broken and large ones thrown into a bucket of water and taken outside. It is necessary to understand that help in case of poisoning
carbon monoxide may not arrive in time, because there will be no one to call it. Monitor your stoves or install them in a separate room.
