Boiler room temperature controller. Thermostat for a heating boiler: temperature controller or something more? Thermostat for heating boiler

Some models of heating boilers are endowed with electronic circuits necessary to expand the functionality and more convenient control of the microclimate in the house. The equipment turns out to be a complex, but pleasing abundance of service capabilities - from automatic temperature control in the circuits to control of external auxiliary units. An undeniable advantage is the ability to connect additional control modules. For example, a thermostat for a heating boiler will maintain the set temperature and provide convenient heating control.

Owners of simple heating boilers do not have to think about the convenience of climate control in the house. Most often, all adjustments on such boilers come down to one simple knob for selecting the degree of heating of the coolant - a simple scale with numbers from 0 to 9 is used here. In the autumn cold, the equipment works on one or two, and in severe frosts, users set the knob to higher numbers.

Thus, the simplest thermostat is used here, focusing on the temperature of the coolant in the system. The required heating level is set manually, and then a simple thermoelement based on a bimetallic plate starts working in the boiler - it turns on the ignition, provides gas supply to the burner. This scheme is used in many simple models.

More advanced boilers regulate the temperature of the degree of heating of the premises as follows:

Models with a remote sensor will regulate the temperature of the exact place where the sensor itself is installed.

• By electronic sensor for controlling the temperature of the coolant in the heating system;
• By remote air temperature sensor;
• By air temperature outside the premises;
• According to the sensor located in the remote room thermostat.

Weather-dependent sensors are used by consumers extremely rarely - people are used to relying on their own feelings. Therefore, they choose to control the temperature of the heating medium or control the temperature of the indoor air.

A remote thermostat for a boiler is an external control module installed at an arbitrary point in a household or apartment. It includes a room temperature sensor and controls. The main function of this miniature device is to monitor the set temperature based on the readings of the thermocouple. With a decrease in temperature, the controller sends a command to turn on the heating to the boiler, and after reaching the set value, turns off the burner.

Thermostats for heating boilers also have additional functionality:

• Adjusting the temperature in the hot water circuit is not the most necessary regulator, but some models have it;
• Setting the day and night temperature conditions - the equipment will automatically lower the night temperature to the set mark;
• Heating control according to a given program - the thermostat will turn the boiler burner on and off, focusing on pre-entered data. For example, we can program equipment for a week ahead;
• Management of external equipment - these are indirect heating boilers, solar collectors and much more.

Due to the remote design, thermostats provide the convenience of controlling the operation of a heating boiler, which can be located in any remote room - this is a kitchen, bathroom or basement.

The functionality of thermostats varies widely. The simplest modifications are a single adjustment knob with a mechanical scale. More complex devices are equipped with several regulators and electronic displays, which display various data. Accordingly, the prices for such devices are higher - they are more advanced, giving users many service functions.

The thermostat for a gas boiler is a full-fledged remote control panel. Judge for yourself - if the boiler is hanging in the kitchen, then in order to reduce the temperature in the heating, you will have to get up from the sofa and visit the kitchen room. If a thermostat were installed in the room, it would be enough to turn the knob or press the button to lower the temperature. Worst of all, if the heating equipment is mounted in a hard-to-reach place - in this case, you simply cannot do without a remote control panel.

In programmable thermostats, you can set different temperature conditions for day and night.

The basis of any thermostat for a heating boiler is a temperature sensor. It analyzes the air temperature in heated rooms, controlling the operation of the burner and other components. By setting the knob or buttons to +22 degrees, you can leave the equipment alone - it will ensure that the set temperature is reached. Whatever the outside temperature is, the room temperature will stay the same.

A programmable room thermostat is more complicated - here we can set a specific heating program. For example, in the daytime we set +23 degrees, and at night we set +20 degrees (at a lower temperature, sleep will be stronger and healthier). We can also set the temperature in the hot water circuit or adjust the degree of heating of underfloor heating.

A more complex and advanced room thermostat for a gas boiler can work with several heating circuits at once, providing separate temperature control.

The thermostat for a heating boiler is just a convenient addition that provides temperature control and management of various service functions. This device is not a mandatory unit of the heating system, in some cases you can do without it. The room temperature controller is useful in large households and in multi-room apartments, when the boiler may be too far away - in this case, the temperature can be adjusted, for example, from the living room.

Let's look at all the advantages of a thermostat for a heating boiler:

Once you set up such a device, you can enjoy a comfortable temperature in your home for a long time.

• Ensures compliance with the specified temperature regime - you can create a comfortable environment in an apartment or house without additional effort;
• Automation of the heating system - the programming function is responsible for this;
• The use of a thermostat will reduce gas consumption by the heating boiler - thereby saving on utility bills.

Unfortunately, it is not without its drawbacks:

• A wired room regulator for a gas boiler requires a cable to be laid - this is easier to do at the stage of building a house than to lay it on top of a repair;
• The cost of equipment - advanced thermostats are quite expensive. Otherwise, you will have to do without additional functions.

The disadvantages are not the worst, so you can put up with them. After all, you have to pay for convenience.

A room thermostat for a heating boiler is a necessary and convenient thing. But there are so many of these thermostats on sale that your eyes run wide. Let's see how these devices differ from each other and what are the features of their work in heating systems. To begin with, let's discuss the division into electronic and mechanical models - by the way, the latter are much cheaper, but inferior in functionality.

Mechanical models are simple and reliable.

A mechanical thermostat for a heating boiler is a temperature controller with the simplest internal device. Inside we will find a simple thermocouple based on a bimetallic plate (sometimes other types of sensors are used) that control dry electrical contacts. The appropriate regulator is responsible for setting the temperature. Due to the simple device, the equipment is distinguished by its low cost. But there is no automation here.

Please note that the thermostat for the heating boiler and the room mechanical thermostat for the heating boiler are two different devices - the first is the internal assembly of the heating equipment.

An electronic thermostat for a heating boiler is a more advanced device. Temperature control in it provides an accurate electronic sensor that records temperature changes with an accuracy of tenths of a degree. The simplest modifications have a minimum set of functions - this is the control of the operation of the heating circuit. More advanced models will please with powerful functionality:

• Hot water circuit control;
• Program work;
• Work with warm floors;
• Date and time display;
• Day and night heating modes;
• Night illumination and much more.

Most of the thermostats for heating boilers on sale are represented by electronic models - “mechanics” are much less common in stores.

Wireless thermostats are very easy to install, as they do not require cabling.

Temperature controllers for heating boilers are divided into wired and wireless. Wired models are more affordable. The connection of the thermostat to the boiler is carried out using a two-wire cable - it is laid under the plaster or laid in skirting boards or cable channels. The optimal cross section of each conductor is 0.75 square meters. mm.

A wireless thermostat is a more interesting thing, since it does not require wiring. The range of this device is up to 100 meters in direct line of sight. In real conditions, it falls 1.5-2 times due to the walls. Worst of all, the signal passes in apartments where the walls are made of reinforced concrete. But there is no need to lay a connecting cable, which is important for buildings where repairs have already been made.

A typical representative of the mechanical category is the Zilon ZA-1 thermostat. This is the simplest model with a relay output, designed to work with equipment that supports the connection of "mechanics". The operating range of the temperature sensor is from +10 to +30 degrees.

This model uses a gas-filled sensor that controls dry electrical contacts. The thermostat is not recommended for installation in rooms with high humidity.

A room thermostat for a gas boiler called Protherm Exacontrol is designed to work with heating equipment from the brand of the same name. But it can work with any other boilers. It regulates the temperature in the range from +5 to +35 degrees, and only in the heating circuit. For convenience of work the device is equipped with the liquid crystal display. The thermostat is designed for those who do not need extra functionality.

The more advanced Protherm Exacontrol 7 model is endowed with a programming function - you can program the operating modes for a week in advance. There are also some differences in the indication, here it is more extended.

From wireless room thermostats for heating boilers, we can highlight the SALUS Controls VS20WRF model. This is a multifunctional device that can control servos. It provides temperature control in the range from +5 to +35 degrees, can work according to one of the programs stored in the memory, and supports the connection of remote sensors. To control the current operating mode, the device is equipped with a large liquid crystal display.

You can buy a suitable thermostat at any store that sells heating equipment. They are represented by hundreds of modifications, both simple and more advanced. After choosing and purchasing a suitable model, you can proceed with the installation. Next, we will tell you how to connect the thermostat to the boiler - there is nothing complicated about it.

Proper installation of the thermostat in the living room.

In order to install the thermostat on the boiler, you should decide on the place of its installation. The device should not be exposed to direct sunlight, it should not be located in a draft zone. It is also necessary to ensure that there are no heaters nearby - otherwise it will be difficult to achieve the required temperature. A two-wire cable is laid from the thermostat to the heating boiler.

In the case of wireless equipment, it is enough to screw it to the wall in any suitable place.

Next, you need to set up the thermostat - for this you need to remove or install a jumper located on the boiler board or in some specific place. So, the unit will be able to understand that it will work with a remote thermostat. After that, we proceed to tests, checks and programming. When using a wireless model, it is paired with the boiler according to the attached instructions.

The temperature sensor for a heating boiler, which is an internal unit of heating equipment, is installed by replacing a failed sensor.

Thermostat for a gas heating boiler: selection rules and self-assembly

The end result of installing an autonomous heating system is to obtain maximum thermal comfort for people living in the house. In addition to choosing a boiler, the future owner must take care of purchasing a minimum set of automation, which includes a room thermostat for a heating boiler. What kind of device it is, what is its role in creating a comfortable microclimate in the room, will be described in this publication.

Why an air thermostat for a heating boiler?

All happy owners of autonomous heating know that a boiler is a device that, by burning fuel, heats the water circulating in the heating system. The heating boiler does not work constantly, but cyclically: it heated the coolant to a certain temperature - it turned off. The coolant cooled down by a few degrees - the boiler turned on. The temperature of the coolant is set manually by the owner, with a thermostat, which is an integral part of any modern heating boiler, regardless of its manufacturer and equipment functionality.

This system of thermoregulation has several rather serious drawbacks:

1. The first inconvenience is that when the weather changes, the owner of the autonomous heating system is forced to visit the furnace room every time and set new temperature values ​​\u200b\u200bon the boiler. This is not always convenient, especially if the boiler is installed in a separate furnace room.
2. In order to maintain the temperature set by the user, the boiler often turns on and off the burner. This leads to an increase in fuel consumption and the development of equipment life.

To solve these problems, most manufacturers of climate technology recommend using room thermostats for a gas boiler. Sometimes on the network you can find the names of this device as: air thermostat, programmer or room temperature sensors.

The principle of operation of the thermostat

The simplest room thermostat is an electromechanical device, the "heart" of which is a temperature-sensitive element filled with gas that expands with increasing air temperature. Upon reaching the user-defined air temperature in the room where the device is installed, the temperature-sensitive element opens the contacts that connect the device with the heating boiler. This action is a signal for the boiler automation or for the gas valve, which turn off the burner or put it into support mode. It all depends on the model and configuration of the heating equipment.

When the boiler stops, the coolant in the circuit cools down. Naturally, this leads to a decrease in the air temperature in the room, while the thermocouple closes the contacts, and the heating system controller restarts the burner.

The advantages of using a room thermostat are as follows: comfort in a heated room depends on the temperature and humidity characteristics of the air, and not on the temperature of the coolant in the batteries. Air cools much more slowly than water. That is why when using a room thermostat, the most comfortable temperature for the inhabitants of the room is maintained with a significant reduction in the number of start-ups of the heating boiler.

In other words: using an air thermostat, you increase the life of the equipment and get a comfortable microclimate in your home, getting rid of the frequent adjustment of the parameters of the boiler unit, saving money on the return of used fuel. Numerous observations show that when using a room temperature sensor, the cost savings for the maintenance of an autonomous heating system is up to 35% per year.

1. Devices that use a cable to communicate with the heating system.
2. Wireless temperature controllers, in which a radio channel is used to communicate with the boiler.

Wired devices are conditionally divided into mechanical and electronic. In mechanical systems, a temperature-sensitive element is responsible for controlling the operation of the boiler plant, an example of which was discussed above. In the electronic thermostat for the boiler, the temperature sensor is responsible for controlling the latter.

Wireless devices consist of two modules: the first is installed directly next to the boiler unit and is connected by cable to its terminals. The second module is mounted in a heated room. It has an informative LCD display and a numeric keypad for setting parameters. Between themselves, the controller and the executive module communicate via a radio channel, the frequency of which does not affect the operation of other electronic equipment in the house.

The wireless group of thermostats can be divided into simple devices, the work of which is only to turn off and turn on the heating equipment when peak temperatures are reached, and weekly programmers, which we will dwell on in more detail.

The weekly programmer is a modern multifunctional device that can not only monitor the maintenance of a fixed temperature, but also has the possibility of hourly and weekly programming of the thermal regime. Most models of programmers are non-volatile and can work with built-in rechargeable batteries.

Today, gsm thermostats for heating boilers have appeared on the domestic market of climate technology. One or two SIM cards are installed in these devices, thanks to which the owner of the autonomous heating system has the opportunity to control the operation of the boiler remotely using a smartphone or tablet PC.

Departing from the topic, we want to inform you that we have prepared comparative reviews on gas boilers. You can get acquainted with them in the following materials:

Do-it-yourself thermostat installation

Although by law all work with gas equipment must be carried out by certified specialists, any home craftsman who has the skills to work with a screwdriver can install a room thermostat on his own. Consider the stages of work on the example of a wall-mounted gas boiler.

1. Power off the device.
2. Remove the outer cover from the heating system. As a rule, it is dismantled by unscrewing 4 screws fixed from the bottom of the device.
3. Loosen the screws securing the control box.
4. Remove the cover from the control box. The task is to get to the control board.
5. On the board you will see a jumper between the "TA" contacts, which must be dismantled.
6. Instead of a jumper, connect a two-core insulated cable (preferably copper) with a conductor cross section of 0.5 - 0.75 mm2.

The voltage that comes out of the control board to the thermostat connection cable is non-hazardous, 24 V. But, when working with electricity, follow all safety rules!

1. Assemble the control box and install the boiler cover in reverse order.
2. Connect the thermostat to the cable according to the instructions for the device.

Advice! If you are connecting a room thermostat that has more than 2 pins on the terminal block, use the ones that indicate a normally open contact. (H, NO). In devices from the Celestial Empire, contacts can be indicated by the numbers 1; 2; 3. You can determine the normally open contact using a tester.

Video on connecting the thermostat to the heating boiler:

1. If you are on a budget, then get a simple, wired, electronic thermostat. Such devices are more technologically advanced, with a better response, and the quality of their work does not depend on contacts oxidized in air, as in mechanical counterparts.
2. If you are concerned about saving energy resources, and at the same time your own funds, purchase a weekly programmer. This device will significantly reduce the temperature in the room, and, accordingly, the frequency of switching on the boiler plant during the hours when all household members are at work.
3. If you have already made repairs, and there is no desire to ditch the walls for cable laying, then purchase wireless air thermostats.

In principle, any room thermostat is like any wall-mounted gas boiler. However, boiler manufacturers strongly recommend connecting only one brand of air thermostats. For example, according to the manufacturer, a room thermostat for a baxi gas boiler should only be of this brand. This is a marketing ploy to attract more customers!

What is a good room thermostat for a gas boiler: choose the best

What is a good room thermostat for a gas boiler

An autonomous way of heating a room is becoming increasingly popular not only in private houses, but also in ordinary apartments. Single- and double-circuit boilers of Baxi or Protherm, Ferroli, Vaillant and other gas-powered companies allow not only to heat the home, but also not to spoil the interior of your house with their appearance.

All items attached to these wonderful heaters are considered by many to be unnecessary nonsense and are called "accessories", without which it is quite possible to do. The boiler heats the water to the required values, then, when the coolant cools down, it turns on again and brings the water temperature to the level you need.

You determine this level yourself, and the task of the device is to turn on every time in order to maintain the program you set. The boiler is configured by you manually and is “responsible” for heating the water, and the air temperature in the room is not its task.

What to do if the air suddenly warms up from the sun's rays above a given norm, or in cold weather it cools down to uncomfortable temperatures?

There are two options for the development of events:

Option one - do nothing and let the boiler itself, turning on and off countless times, heat up the coolant.

Option two - to purchase a device called a room thermostat for a gas boiler, thereby guaranteeing warmth and comfort to your home and protecting a rather expensive heating device, in this case a boiler, from rapid wear.

Mechanical room thermostat

A room thermostat or temperature controller can by no means be attributed to unnecessary accessories, because. this device regulates the operation of the boiler and provides heating not of water, but of air, and, as you remember, the boiler is not responsible for this.

Water cools much faster than air, and the boiler needs to be turned on approximately once every ten minutes to maintain the required temperature. The pump of the device in this mode works without ceasing and wears out soon enough.

And what happens to the boiler to which the room thermostat is connected? Let's figure it out to draw a conclusion about the need for this device or about its complete uselessness.

The principle of operation of a room thermostat

The room thermostat is a modern compact device that allows you to control and regulate the air temperature in the room, the value of which you determine yourself. In some European countries, for example, this device is considered mandatory for installation in any home, and I don’t need to explain how Europeans can literally save on everything.

So, when the air temperature drops by at least 0.5 degrees, the thermostat gives a signal to the boiler to turn on, and that, accordingly, heats the water, raising the air temperature to the desired numbers.

If the temperature is kept at the level of the indicators you have determined, the boiler does not turn on, saving gas and electricity so much that the payback of the device itself comes very quickly.

Gas and electricity bills constantly surprise us in terms of growth, and I think it would not be superfluous for anyone to save up to 25-30 percent of the family budget only on the operation of the thermostat. This is such an "accessory"!

What about boiler operation? Can you imagine how many times its circulation pump will need to turn on less often if the thermostat controls the operation of your heating equipment? The service life of the boiler is doubled.

Let's define the advantages of a room thermostat:

The device maintains the desired temperature in the house, creating an atmosphere of coziness and comfort;

When the thermostat is connected, there is no need for constant monitoring of the boiler and its regulation;

Saving money and quick payback of the device.

Main types of thermostats

Room thermostats can be divided according to the way they act on heating equipment (in this case, a gas boiler) and according to the quantity and quality of the functions they perform.

According to the method of regulation, thermostats are divided into 2 types:

Wired;

Wireless.

For the first type, it is necessary to connect the device directly to the boiler, and the thermostats of the second type control its operation using a radio signal.

In the wireless thermostat, two devices are located at once, one next to the device, the other in the room from which thermal control will be carried out. The devices are connected to each other by radio signal.

Room thermostat for the Baxi boiler

The unit located in the room is equipped with a display on which you indicate the temperature of the air in the room that is gentle to you, i.e. program it to work. That is why these types of thermostats are called programmers.

Features of room thermostats for boilers

According to the set of functions performed, thermostats are also divided into two types:

Simple or mechanical;

Programmable.

Simple room thermostats have one function - they keep the required air temperature, that is, they play their main role. Programmable thermostats are able to interfere with the operation of the boiler even at a distance.

You can set a program for such a device for a week and a month in advance, you can change the temperature from day to night, you can program the device in such a way that the house will welcome you with warmth exactly at the moment you arrive after work or after a long business trip.

If you have already decided to purchase a room thermostat for the boiler, but do not chase the high cost, start with the simplest model, and only when you realize that you really need the device, get a more complex design.

And also analyze the conditions of your room: it happens that wired devices simply cannot be connected in this room, then your choice will be limited only to wireless thermostats.

Mechanical room thermostat for gas boiler

When buying a device, get a qualified explanation from a specialist and use some tips:

1. It is better if you purchase a thermostat from the same manufacturer as your gas boiler. In this case, installation and installation will be easier and control over gas equipment will be more reliable. Although many people buy various devices that successfully function for a long time and well.

2. Be sure to consider the size of the room in which the appliance will be installed and the amount of temperature it will control.

3. It will not be superfluous at all if a layer of heat insulator is additionally laid in a room equipped with a thermostat, in this case the savings of your material resources will increase significantly.

4. Since the room thermostat is “responsible” for the air temperature in the room, there are a number of restrictions in its use, which we list below:

Do not install the device near objects that prevent free air circulation;

Do not cover it with decorative elements - shelves, curtains, etc.

Programmable thermostat for gas boiler

Do-it-yourself thermostat connection to a gas boiler

According to the principle of operation, a room thermostat is very similar to a car one, but, unfortunately, the latter cannot turn off the internal combustion engine, and the room thermostat will turn off the gas boiler at the right time, preventing it from overheating the air in the room.

Many are stopped by the fact that it is necessary to call a competent specialist to install the thermostat, but this is completely optional. You can safely install the device with your own hands, if you take into account some recommendations:

Getting started, it is necessary to drain all the water from the system by opening the inlet valve; .

Purge and unplug adapter;

Tighten the nuts located between the adapter and the valve, taking care to keep the threads intact.

The basic rule for the operation of a room thermostat is to protect it from any mechanical damage, because. in this case, very sensitive elements of instrument sensors can be damaged.

Each room needs a separate thermostat, take this fact into account when calculating the financial resources that you intend to allocate for the purchase from your budget.

Each room has its own temperature - higher for the nursery, slightly lower for the bedroom, etc. Make sure that the doors between rooms are tightly closed, otherwise the operation of the device will be difficult. Let's watch the video.

Manufacturers and prices

As for the price of thermostats, for example, the simplest device for a Baxi or Protherm boiler will cost you $ 35-45. At the current rate, it is a little expensive, but do not forget that the device will pay for itself soon enough, and the savings on electricity and gas will also be tangible. The choice is yours!

How to choose a room thermostat

A constant, comfortable temperature in the living quarters ensures the warmth and comfort of the hearth. Taking into account the prices for gas and electricity, careful attitude to energy resources is not an idle issue. The market offers a variety of heating appliances with economical fuel consumption. To maintain a stable temperature and save energy in the house, it is not enough to install a heating boiler, it is wiser to immediately purchase a room thermostat. The thermostat will automatically maintain and control a stable air temperature, relieving a person from constant worries about manually adjusting the thermal regime.

Types of room thermostats

When thinking about buying a room thermostat, you should determine for yourself which operating functions of the device are most important. The offers of the modern market are distinguished by a wide choice of thermoregulation devices, they have different functional features, differ in the technique of execution and measurement accuracy.

Regulators have differences in the installation technique, the number of functionalities, in internal technical devices.

According to the technique of fixing on the walls, thermostats are divided into:

• wired - mounted using a wiring system connecting the device directly to the boiler. The radius of action is more than 50 meters, regardless of the material component of the walls;
• wireless - the process of temperature control is carried out by a radio signal from the first unit of the device (mounted next to the boiler) to the control unit. The disadvantage is a decrease in signal strength and a limited range with reinforced concrete walls.

According to the quantity and quality of the technical functions of the device, there are:

• simple - maintain the set temperature;
• programmable - set the required heating mode automatically, lowering the temperature without the presence of a person. Reducing the temperature by 1 degree saves 5-6%.

The operation of the device depends on the type of temperature sensor installed in the technical device, they differ:

• mechanical - based on membrane or capillary sensors;
• electromechanical - based on an electrical relay;
• electronic - based on thermistors.

Mechanical thermostats for heating boilers

Most often, mechanical room thermostats are used when installing a gas boiler. Gas-fired heating appliances are more easily compatible with a mechanical type of thermostat. The membrane sensor works on the principle of closing / opening, depending on the pressure in the gas chamber. As soon as there is a change in the volume of gas (the boiler has overheated or cooled down), a signal is sent to the control device through the electrical circuit and the heating boiler is automatically turned off / on.

The temperature mode is set by turning the round knob with a division scale. By turning the knob, you can move the membrane closer or further away from the control device by selecting the temperature indicator that determines the contact connection / disconnection.

Electromechanical thermostats for heating boilers

Electromechanical thermostats have a wired connection and are used for heating with solid fuel and gas boilers. They have a more complex design compared to mechanical devices. The temperature-sensitive element consists of a bundle of a pair of metal plates of a special alloy. With an increase in temperature and a significant heating of the element, a microdischarge occurs, which activates an electromagnetic relay that regulates a mechanical valve. The electromechanical device maintains the set air temperature.

Important! Electromechanical room thermostats do not form a harmful electromagnetic field, the transmission of low power pulses occurs for a short time.

Electronic thermostats for heating systems

Electronic thermostats - a modern and most functional device, it is installed for heating appliances with any type of energy carrier. The electronic room thermostat allows you to set the operation of the device for any period, from several hours to a week. Contains more than 40 types of programming. Time timers allow you to set different control patterns for weekends and weekdays, it is possible to set different parameters for every day and at any time of the day.

The latest models provide for the transmission of information about the thermostat readings by mobile communications via SMS messages. Wi-Fi technology, supported by leading manufacturers, allows you to configure heating equipment via the Internet, special applications for smartphones have been developed. This type of device can significantly save fuel.

The purchase of an electronic thermostat is better correlated with the company that produces heating boilers, it is easier to carry out installation work and control the functionality of the equipment.

The room thermostat for the Baxi gas boiler has good performance:

• has a reliable, wired connection to the heating device;
• supports multi-level thermal regime from +5 to +40 С;
• sets the “climate” for any period of the day, the minimum frequency is half an hour;
• a large, readable display shows the operation of the thermostat - days of the week, hours, temperature, set program.

The Baxi thermostat is controlled by a remote control or by telephone.

Room thermostats for electric boilers

In areas remote from large cities, where there is no gas supply, boilers powered by electricity are installed. The advantages of electric boilers include environmental safety, simple installation work, almost silent operation and the absence of a chimney. There is only one, but an important minus - a large overrun of electricity, which entails a high cost of operation.

For boilers using electricity, the installation of a thermostatic device will reduce energy costs by 20 - 25%, and will allow you to set the thermal regime in each individual room. A room thermostat for an electric boiler can be wired or wireless, mechanical or electronic. The device is selected according to the quality and quantity of functional options required for the owner.

Room thermostats for radiators

In private households, it is possible to automate the entire heating system without problems, for residents of apartment buildings it is a little more difficult. In the apartment, to ensure a comfortable temperature, thermostats are installed on heating radiators. The easiest option is to install a manual thermostatic head that works like a conventional faucet. The device is reliable and cheap, but not the most convenient; to change the heat transfer, the valve is turned by hand.

For heating batteries, a mechanical device based on a capillary sensor is more often installed. When the liquid overheats and expands in a special chamber, the valve of the device gradually blocks the access of the coolant to the radiator. Install a thermostat in front of the inlet or outlet of the heating pipe from the radiator.

Thermoregulators for batteries with electronic "stuffing" have an additional set of useful functions. The programmed device “turns on / off” the radiator according to the temperature in the living room. These models are the most accurate, some disadvantages are the large size of the device and the rather high price.

Temperature controllers for heating boilers: types, prices, characteristics. Given the rise in energy prices, the issue of energy conservation is extremely acute. That is why a large number of models of heating devices that consume fuel economically have been developed. However, the equipment itself is not enough. The most rational use of energy resources will help the thermostat for the heating boiler (thermostat), which allows you to control and maintain the set air temperature in the heated room.

The thermostat is designed to set the optimum temperature in the room

Purpose of thermostats for heating boilers

To be able to control the energy consumption of heating equipment, it is equipped with special devices - thermostats. These devices allow you to use fuel efficiently by turning off the equipment when the set temperature level is reached. Thermoregulators are used for electric boilers, gas and solid fuel boilers, as well as convectors, heaters and other heating systems.

The thermostat is able to respond to temperature changes and turn on and off the heating equipment in automatic mode

To achieve economical operation of the heating boiler, the thermostat turns on the equipment when the temperature drops below the set temperature and turns it off when the set value is reached. This method avoids unreasonable consumption of gas or electricity, when, for example, some of the rooms are located on the sunny side and less heat is needed to heat them than for other rooms.

Helpful advice! Even a slight decrease in temperature within 1 degree helps to reduce energy consumption by 4-6%.

In addition, with the help of thermostats, you can set the operating mode of the heating system, in which the temperature in the absence of people in the house or at night will be 4-5 ° C lower. Thanks to this, savings in electricity or gas consumption of about 30% can be achieved. Thus, if your heating equipment does not have such a built-in device, it would be advisable to buy a thermostat for a heating boiler. The temperature controller will provide a solution to the problem of energy overruns.

Using the thermostat, you can set different heating modes for different times

Types of thermostats for heating boilers

Equipping heating equipment with thermostats allows you to maintain a given temperature climate in the room with an accuracy of 1 to 0.5 degrees. They control the operation of the heating system using various actuators. There are electromechanical and electronic thermostats. The design of a mechanical thermostat for a heating boiler has an on / off key and a rotary button to control the temperature.

Electronic or programmable thermostats are more advanced, but simple and straightforward to use. With their help, you can set the daily temperature cycle: in this case, the boiler will automatically switch to the specified mode. Such devices can regulate both the entire heating system and individual heating units.

There is a classification of devices into wired and remote-controlled. For the former, the connection of conductors is important, as well as external protection against mechanical damage. The quality of the signal supplied from the boiler to the controller, which informs about the flow of coolant into the circuit, depends on this. During installation, the question may arise of how to mask the signal line so that it is invisible.

The simplest type of thermostat is mechanical

In the wireless thermostat for the boiler, control is carried out by transmitting a radio signal. Such a device has two blocks, one of which is mounted in close proximity to the heating boiler, connecting to the equipment terminals. The second node is located indoors. There is a dedicated radio channel between the two blocks. The control unit is equipped with a display and a control keyboard.

Depending on the degree of automation, thermostats can be digital or analog. The operation of digital devices is based on the signal of microcircuits, due to which the device can fix and apply several specified modes. Analog thermostats are controlled manually by means of a mechanical regulator connected to a rheostat.

Thermostat for a heating boiler (thermostat): which one is better to choose

Before you buy a thermostat for the boiler, you need to decide on the type of device. To do this, you need to understand what is the fundamental difference between models of room mechanical thermostats and electronic ones. There is an opinion that the latter are difficult to configure and they are unreliable, but this is not so.

The electronic temperature controller is more accurate and has the flexibility of settings.

The principle of operation of a mechanical thermostat for a heating boiler

In most cases, mechanical thermostats for heating boilers are used in gas installations. This is due to the fact that manufacturers of gas boilers initially produce devices that are compatible specifically with mechanical models of thermostats. The design of a mechanical thermostat has a gas membrane, inside of which there is a special gas.

When the temperature deviates from the norm, the volume of gas inside the membrane changes and the mechanism for closing or opening the heating boiler power system is triggered, respectively. This is a fairly simple way to control the operation of the boiler, when its operation depends on the temperature indicator not of the coolant, but of the air in the heated room.

Using a mechanical thermostat model, you can set an acceptable temperature by turning a round button with divisions, which is connected to the membrane. Thus, there is an approach or removal of the walls of the membrane to the control device: this is how we set the temperature at which the connection or break of contact will occur.

Scheme of connecting the thermostat to the heating boiler

After the model is selected, the question arises of how to connect the thermostat to an electric boiler or gas heating unit. The device is connected according to the recommendations specified by the manufacturer in the technical data sheet for the equipment. It is only necessary to find the necessary section in the documentation, which will describe the method of connecting additional devices to the boiler and provide all the required diagrams.

Scheme of connecting a room thermostat to a heating boiler

On some models of thermostats, the diagram is shown on the back of the decorative cover. All modern boiler models have connection points for a thermostat that will control the operation of heating equipment. Fixing the device is carried out by means of a terminal on the boiler at the appropriate point or using a thermostat cable (included in the kit).

According to professionals, wireless room thermostats should be installed in living rooms away from existing household electrical equipment (TV, refrigerator, lamps, etc.), since proximity to the heat radiated from them can lead to incorrect operation of the device. Some recommendations for installing a wireless thermostat for a gas boiler:

• for the correct measurement of the temperature in the room, it is necessary to ensure free access of air to the thermostat;
• it is not recommended to cover the devices with furniture or heavy curtains;
• the device should be located in the coolest rooms or in residential areas where residents spend the most time;

It is necessary to install the thermostat in an open area away from heating devices.

• avoid direct sunlight on the device;
• do not mount the device near radiators or heaters;
• the devices must not be located in the draft area.

Helpful advice! Room thermostat sensors for heating are triggered when the room temperature changes by 0.25 degrees.

Heating control with a thermostat for a gas boiler

You can control the operation of heating equipment using the manual setting or by means of a thermostat for a gas heating boiler. I would like to note that using manual settings, you can set the temperature of the coolant in the system. Such functioning of the equipment does not react in any way to changes in the air temperature in the room, and if this occurs, you will have to manually reconfigure the boiler again.

You can control the operating modes of a gas heating boiler both manually and through a thermostat

The operation of the boiler in the case of manual control is associated with frequent switching on and off of the equipment, as well as the operation of the circulation pump, regardless of whether the unit is in operating or standby mode. This causes heating equipment to wear out quickly and does not contribute to efficient fuel consumption.

If we are talking about control using a thermostat for a gas boiler, then such a device sets the optimal mode for the unit, taking into account the air temperature in the heated room. If, for example, there was a sudden warming and the room received additional heat from the sun's rays, the thermostat will instantly react and give a signal to the control device to turn off the boiler.

Considering that with the help of a thermostat (temperature controller) for a gas boiler, you can set the required temperature in the room, heating will be carried out only if it is lowered. Thus, if the device is set to 20°C, and during the day the room is also warmed up due to the heat of the sun or the operation of cooking appliances, the boiler will be in the waiting state for a long time.

The thermostat helps to reduce heating costs by 30-40%

In this case, fuel consumption will be significantly lower. Before you buy a thermostat for a gas heating boiler, you should ask how to properly configure the device.

Setting the thermostat (temperature controller) for the heating boiler

After you buy a thermostat for a heating boiler and connect it to heating equipment, it will need to be configured. Each product comes with an instruction manual that explains how to set it up. Having carefully studied it, you can independently set the necessary mode that meets the individual level of microclimate comfort.

On the external panel of the device there are buttons and switches, through which the setting is carried out. The switches allow you to control the heating and air conditioning of the air space, start delay (does not allow the boiler to start when the temperature drops for a short time, for example, a draft) and temperature deviation (if you set the fluctuation value to 1 ° C, then switching on or off will be available when the temperature rises or falls by 0.5 degrees).

For the correct setting of the operation of the thermostat for the heating boiler, it is better to contact the specialists

By means of buttons two modes are set: optimum and economical. Thus, during the day the temperature will be at the optimum value, at night the temperature will drop to a level sufficient for a pleasant sleep. This mode will significantly save on energy resources. Various models of thermostats have several preset modes, one of which can be selected for use.

Helpful advice! In rooms where children and the elderly are most often present, it is recommended not to lower the temperature below 22°C.

The function of heating boilers is to heat the coolant and utility water.

For automatic operation of heating equipment, thermostats for boilers are used.

The need to install temperature controllers in the heating system is due to several factors:

1. An increased temperature of the coolant can cause an accident, so it is necessary to install a monitoring sensor to protect against such situations.
2. Due to the different outdoor temperatures, there is a constant change in the indoor air temperature. To maintain the optimal mode, it is necessary to install a regulating sensor.

Thermostats have different types and purposes.

The thermostat is a device that controls the operation of the boiler depending on the temperature. There are room thermostats - they regulate the temperature of the air in the room. There are thermostats that control the temperature of the coolant. Their principle of operation is based on the thermal expansion of the body and the closure of contacts, or on the basis of temperature controllers.

Based on the signal from the coolant temperature thermostat, the boiler is automatically switched off when the temperature in the supply line rises above 95 0 С.

The room thermostat is installed in the place where the true air temperature will be reflected. The thermostat must not be placed close to heaters or windows.

The thermostat is connected to the boiler in accordance with the passport connection diagram of the sensors. Each boiler has its own scheme.

Radiator thermostat

A radiator thermostat is a device that regulates the flow of coolant to each heating radiator individually. It consists of a mechanical part (valve) that reduces or increases the coolant flow and a control part (thermostatic element).

The principle of operation of the thermostat is as follows: the valve stem is connected to a thermostatic element, which is a vessel with a gas or liquid. When heated, the liquid and the vessel expand, as a result of which the effect on the valve stem and the flow rate of the coolant decreases. After the thermostatic element cools down, the liquid and the vessel contract and the valve opens automatically.

The choice of thermostat should be made in accordance with the hydraulic calculation of the heating system and its connection diagram: two-pipe, one-pipe, forced circulation or gravity.

To set the required temperature, the valve is equipped with a control mechanism with a scale.

There are also electromagnetic sensors that must be connected to the mains. Their work can be controlled remotely, as well as complex time programming. For example, set a cool mode in the bedroom at one time, warmer in the living room, and vice versa at night. This will ensure not only the creation of comfortable conditions, but also save fuel.

The vertical installation of the thermostatic element has a more aesthetic appearance, however, its operation in this position may not be correct (due to ascending warm air currents). It is best to place it horizontally.

Programmable room thermostat

A programmable room thermostat is an electronic device that regulates the air temperature in the room and controls it by changing the operating modes of the boiler. A feature of the programmable thermostat is the ability to create a temperature program for the future, taking into account the time of day.

The operation of the room thermostat is carried out on the basis of remote sensors. They are installed in optimal areas where there are no heating devices or sources of cold.

The room thermostat contributes to a more economical operation of the unit, and also takes into account the weather influence on the indoor climate.

Central thermostat

Central thermostat - affecting the entire heating system. As a rule, the thermostat is installed at a distance from the boiler and can be connected to it using wires or a wireless system. The device is attached to the wall and connected to the electrical network, after which it is connected to the boiler.

Thermoregulators provide safe, economical and comfortable operation of the heating system and allow you to set an individual temperature regime for each room.

When the house has a heating system using a gas boiler, you have to manually adjust the optimum room temperature. Moreover, this heating option is very sensitive to weather changes. As soon as it gets colder outside, you have to increase the temperature of the coolant. Even expensive models with a high level of automation require these actions. To save consumers from such work, manufacturers have released a thermostat for a heating boiler (temperature controller).

Smart device options

Thermostat for a heating boiler (temperature controller): how it works

The installed heating system from heats the room to the set temperature, regardless of the level of heat or cold inside. At the same time, a person feels well the daily changes in the weather, if he does not change the mode manually.

To eliminate this problem in a small house without a second floor, it is enough to mount one thermostat in the passage room.

Note! It is necessary to connect and mount the device correctly so that it works correctly and sends a signal to the boiler.

The design of a simple device includes an element with high sensitivity (actuator) and a contact group with a regulator. In appearance, it is a closed bellows, inside of which a gas mixture is usually placed, sometimes a liquid. This filler reacts to temperature changes and moves the rod to close the contacts when the temperature rises, and when the temperature drops, the reverse action occurs.

The thermostat performs the task of turning the heating system on and off when the set temperature is reached autonomously, without human intervention. A simple circuit includes two contacts, the wires of which are led to the boiler and connected to the valve.

When the device is turned on, the last element is in the open state. When a short circuit occurs, the fuel supply to the burner is cut off and the flame stops. In the reverse process, ignition occurs from the igniter.

Varieties of home temperature sensors for a heating boiler

Temperature regulators for a heating boiler (temperature regulators) come in several varieties:

• Wired. The key to correct operation is the correct installation of conductors. This is necessary for uninterrupted communication of the equipment with the boiler.

• Wireless. With the help of a radio signal, information is supplied about changes in the temperature regime in the apartment. The device consists of two blocks, one of whichmounted in the room, the other on the boiler itself. The controller unit has a liquid crystal display and a keyboard.

We will analyze each option in more detail, with an approximate cost and an overview of several models.

Mechanical (wired) thermostat

The thermostat for a mechanical heating boiler has its own characteristics, the price for the models is different as well as the characteristics. Such a device must be pre-configured in order to achieve the optimum room temperature. This is a complex process, so it is better to contact a specialist.

The package of any model includes two parts: a thermal head and a valve. The operation of the device is affected by:

• frequent ventilation;
• bright sunlight that enters through the windows;
• sudden change in weather.

Installation must be carried out only in a horizontal position, while choosing a place where there are no objects blocking the device and direct sunlight. Modern models provide for small dimensions that can be installed in a small niche.

The installation itself won't take long. If you turn off the heating, then you need to turn the thermostat knob. This will protect the device from the formation of sediment.

Here is an example of two popular mechanical thermostat models:

Mikhail's review, Balabanovo:“I got it two years ago, installed it myself, not far from the boiler. Works well, the house is always warm.

Dmitry's review, Tver:“Heard a lot of good reviews, bought a month ago. There were no problems with installation and configuration. As long as everything suits.

Mechanical room thermostats for a gas boiler are popular, have a low cost and can be self-installed.

Important! Correctly set up a mechanical device before use, otherwise there will be no result. It's better to call a specialist.

Remote equipment options

The thermostat for the heating boiler (temperature controller) can be operated remotely.

There are several types of such a device:

• simple;
• software rooms.

The first option is designed to maintain the desired temperature in the room. And when installing the second option, the owner of the premises receives the following advantages:

• remote control;
• you can set the mode depending on the time of day;
• speed of mode change;
• you can schedule changes for a week;
• quick response of the boiler to changes;
• low fuel consumption;
• battery is used.

Remote software temperature sensors (room) for gas boilers are designed for people who love the maximum level of comfort and new technology. Here are some popular options for such a device:

Model name	Specifications		Price in rub.

	Mounting type	Overhead
	Temperature regime	+5 to +39 ⁰С
	Block sizes	91*113*33mm
	Timer	Weekly

Feedback from Denis, Moscow:“I also have a Bosch gas boiler, so I bought this thermostat. Works half a year without problems, planning for a week supports properly.

Feedback from Ekaterina, Bryansk:“I suffered for a long time with manual adjustment of the boiler. Then I installed Siemens REV13 (I hired a specialist). I have been managing the temperature simply and quickly for a year now.”

Software temperature sensors for a heating boiler are different in cost and function. At the same time, all models do an excellent job of controlling the temperature in the room, and the convenience of adjustment allows you to add heat to the house without getting out of bed.

The thermostat for the boiler not only saves our money by reducing the volume of gas, but also increases the life of the equipment. Such a device is definitely worth having in service, but what should it be?

How does the operation of a gas boiler with a thermostat change?

The diversity today is simply amazing. They have many modifications, operate on various types of fuel. But it is very important to ensure the correct management of such units. This will reduce energy consumption, and therefore reduce costs, extend the life of the equipment and achieve an optimal microclimate in every room. All these tasks are within the power of special temperature controllers.

Gas boilers have a cyclic scheme and turn on after the temperature of the water or other coolant drops to a certain value. At the same time, the rate of heating and cooling of the water in the system and the air in the room is different. Often the room still has the right temperature, and the coolant in the system has already cooled down, so the gas boiler burner turns on. This leads to an undesirable change in the microclimate, excessive fuel consumption and wear of the heating equipment. It is inconvenient to regulate this process manually. By installing a special device, you will avoid such problems.

These devices are equipped with a sensor that measures the temperature in the room. You yourself set its optimal values, and as soon as it gets cooler in the house, the device immediately turns on the pump and starts the gas boiler. After exceeding the specified threshold, the heating equipment is automatically turned off.

What can be a thermostat for a boiler?

Today, the choice of such devices is quite large, you can find wired and remote models, programmable and simple, mechanical or electronic. Depending on the type and number of functions, the cost will differ. Now let's look at the main differences between existing thermostats.

The simplest and cheapest, of course, are mechanical models, and this is precisely their main advantage. Such equipment is easy to operate and relatively easy to repair. And the probability of failure is reduced to a minimum. The more expensive is electronic equipment, which is also very unpretentious.

But programmable temperature controllers are already complex devices. To install them, configure them correctly and change the parameters, you will have to tinker a bit. However, having done these operations 1-2 times, then you will easily cope with similar tasks. They provide more precise control, have many functions. For example, in some models, you can set the desired temperature in the "day" and "night" modes or program the heating system depending on the days of the week. The remote control is very convenient. True, all this will affect the cost of the device.

If you prefer wired thermostats, pay special attention to installation. It is important to ensure uninterrupted communication between the control device and the heating equipment. Wireless regulators provide start-up and shutdown of the gas boiler using a radio signal from the control point to the executive one. The first is installed in the selected room, and the second directly on the boiler.

Is it difficult to install the sensor?

The maximum efficiency of thermostats for gas boilers is possible only after proper installation. What is so difficult here? Let's run through the instructions.

How to install a thermostat for a gas boiler - step by step diagram

Step 1: Choosing a thermostat

It is desirable that the thermostat is of the same company as the boiler. This will greatly simplify the installation process. If you decide to use wired sensors, then they must be installed before the start of repair work, otherwise you will have to damage the finish in order to lay the cable. It is also necessary to calculate the heated area before buying a device, this will help to avoid equipment downtime.

Step 2: Choosing a Location

When it comes to remote devices that are installed anywhere, it is important to choose the right room. It is advisable to choose the most visited, for example, the living room. Sometimes it is placed in the coldest room, it all depends on the needs. The sensor must be located in an open area. It should be excluded from cluttering it with furniture, curtains and other household items. It is also not allowed to place in the vicinity of electrical and heating appliances. It is also undesirable to expose the device to sunlight or drafts. If valves with thermal heads are installed in the room where the control sensor of the thermostat is installed, then they must be replaced with ordinary ones with manual adjustment. Otherwise, they may distort the readings of the device, and the system will not work correctly.

Step 3: Connection

First you need to carefully read the attached instructions, diagram and act only in accordance with the manufacturer's recommendations. You can connect the device either using the terminal on the gas equipment or by connecting the cable. It all depends on the chosen model. The control element must be placed at a height of 1.5 meters from the floor and on the inner wall. This is due to the fact that warm air is at the top, cold air, on the contrary, is concentrated from below, and the outer walls are colder. Before connecting, be sure to de-energize the object, and then connect zero, phase and ground.

Step 4: Setting up

Now you need to set the required parameters. Usually there are buttons on the front panel of the device, with their help the necessary settings are made. In this case, the technical documentation of the device is again useful, which describes the programming process in detail. The step and heating temperature are set. There is also a thermostat delay function. For example, with short-term drafts, the device detects them and does not turn on. More expensive models may have a number of other options.

.

If you are in doubt whether you need to purchase expensive equipment, then you can always experience the effect on cheaper and simpler mechanical models. Avoid downtime and replace batteries in a timely manner.
