Boiler Hearth device:
Structurally, the Hearth boiler is made in such a way that it can be fitted into any heating system. The front door can be re-hung as required and opens from either the left or right side. Two return lines, from the side and from the back, make it possible to supply the heating medium from the convenient installation side.
The Hearth boiler consists of:
- Boiler body
- Control automation
- Heat exchanger
- Second circuit (if the boiler is double-circuit)
- Safety system
In the lower part of the body, there is a combustion chamber; it is closed from the side and back with sections of the water jacket. A heat exchanger is located above the combustion chamber. High efficiency of heat transfer and heat exchange between the exhaust gases and the coolant is carried out due to the developed convective part of the heat exchanger, consisting of “flame” tubes.
In the upper part of the heat exchanger there is a smoke collector with a built-in draft stabilizer. In the front part of the smoke collector there is a draft sensor, in the upper part of the smoke collector there is an outlet pipe of the boiler. When installing the boiler into the chimney, it is necessary to coordinate the diameter of the outlet pipe with the cross-section of the chimney. The technical parameters of the chimney must correspond to the technical parameters specified in the operating manual.
In the middle part of the smoke collector, there is a partition plate to ensure stable operation of the device regardless of weather conditions. The heat exchanger, complete with the smoke collector, ensures the efficient operation of the boiler without consumer intervention, and does not require manual adjustments. Stabilizer draft contributes to the stable operation of the boiler in case of unstable draft.
A gas burner device of Russian production by Service Gas company is installed in the combustion chamber of the apparatus. It consists of a front panel, burner pipes, safety sensors (flame sensor and draft sensor), and a SABK AT control unit.
Below, under the burner tubes, an easily removable distribution grid is mounted. Designed to supply secondary combustion air. It is very important to ensure free air access through the lower part of the boiler along the distribution grid to the burner pipes when installing the boiler in the room.
The boiler must be installed with a clearance to the height of the foot relative to the floor. Boiler The hearth is connected to the gas mains on both the left and right sides. This allows the design of the SABK AT unit. A temperature sensor is installed on the front panel, which indicates the temperature in the room.
Boiler Hearth how to light it up?
In order to ignite the Hearth boiler, it is necessary to turn the control knob clockwise until the point is opposite the pointer. Then press and hold the start button. Press until a characteristic click, the piezo ignition button. At this time, the pilot ignites. Keep the start button pressed while the thermocouple heats up. The gas block operates automatically on the igniter. Next, turn the knob counterclockwise to the required temperature.
The hearth gains high efficiency due to efficient combustion of fuel and high heat transfer from flue gases by means of “flame” pipes to the coolant and a developed firebox. The service life of the manufacturer is guaranteed for at least 15 years. The factory warranty for the product is 24 months.

Why does the gas boiler go out?
The fading of the flame of a gas boiler can be caused by external or internal reasons.
External reasons include:
- Reverse thrust... The most difficult case, almost impossible to eliminate by conventional means.Sometimes it helps to eliminate drafts, to open or close some doors or windows.
- Strong gust of wind outside... Cases of flame blowout by the wind are frequent, they are the result of an unsuccessfully located chimney or a low height above the roof surface.
- Drafts indoors... This situation is quite solvable, the main thing is to determine the source of the draft and close it.
Internal problems can be:
- Cut off the gas supply to the mains.
- Gas valve failure, problems with gas equipment.
- Burner nozzles clogged with soot and combustion products.
In case of such problems, you should call the gas service and clarify the reasons for the lack of gas. The fuel supply valve must be closed before this.
Call a specialist from the service center and entrust him with the repair of gas equipment.
It is forbidden to try to repair the gas block on your own; this can cause very dangerous and even fatal consequences.

The house is large, with an area of 300 sq. M., Water-heated floors are installed on the entire ground floor. Batteries are naturally on both floors. They are heated by the manufacturer's boiler Hearth 31.5. In addition to batteries and underfloor heating, the boiler also works to heat the water in the house. Problems with the boiler began immediately, I really could not light it up. Even with a full load of briquettes and with two heating elements, the maximum temperature that could be reached when heating the water is 40.
And he never put everything at the same time, he only turned on, for example, water and floor or batteries and water. I am not a builder and far from all these matters, so I could not immediately figure out what the problem was. But in the end I realized that the whole problem turned out to be in the chimney, the builders set the pipe diameter to 110 for me. But as it turned out, this was not enough for such a boiler, the boiler burned quite a bit and the smell was bitter-sour during combustion. I expanded the chimney by 200 and the problem disappeared. True, the boiler still had to be cleaned of the tar that had previously flowed out of the furnace.
Maintaining an acceptable temperature in the room during the cold season is not only a guarantee of a comfortable stay in it, but also a guarantee of the longevity of the house. It is expensive to be heated with electricity, wood is not very convenient, it remains to choose the best gas heating boiler, which has been proven over the years, and with its help create optimal living conditions. There are so many of this equipment on the market and it is not cheap, so it is important to decide in advance on the choice that will help make our rating.
Major malfunctions
The main malfunctions of gas boilers The hearth is problems with the burner - a weak flame, attenuation after a few seconds of burning, frequent flame outages for unknown reasons.
There can be many reasons for a malfunction of gas equipment; to eliminate possible problems, knowledge of the design and features of the equipment operation is required.
All work must be carried out by service technicians authorized to work with gas equipment.
The only possible independent procedure may be to clean the burner nozzles from soot.
The device and operation of gas-wood boilers
A universal gas-wood boiler for home heating, available in three different modifications, differing in design and functionality:
- Module, with the possibility of converting to gas.
- A boiler that has two combustion chambers at once, separately for firewood and gas.
- Heat generator with built-in electric heating element.
Combined boilers of mixed type, for gas and firewood, have built-in automation that fully automates the combustion process. After the firewood burns out in the firebox, the module automatically switches to gas or electricity. For hot water supply, water is heated by an electric heater.
Bi-fuel wood-gas boilers
Combined gas-firewood boilers are widely used in domestic conditions. The design includes the following units:
- Combustion chamber - made of steel or cast iron. One or two fireboxes are installed in the design. Modification with two combustion chambers, more convenient. A gas burner is installed in the lower furnace. In the upper chamber there are grate bars for burning firewood.
- Heating and DHW circuits - manufacturers produce models designed exclusively for heating (with the possibility of subsequent connection to an indirect heating boiler), as well as for receiving hot water and heating rooms. The latter are completed with two circuits. DHW is heated in a flowing manner.
Heating water for hot water supply, depending on the capacity of the boiler TT, reaches 700 l / h. There are modifications with a built-in storage tank for 40-120 liters of water.
Electric-gas-wood boilers
Combined heating boilers, gas, wood and electricity, have a device that resembles that of dual-fuel units. The main difference is the installed electric heating element. The principle of operation of combined boilers, gas, firewood, electricity, is as follows:
- Firewood is considered the main type of fuel. After the wood has burned, the gas burner is automatically turned on. The heating process continues without interruption.
- The heating element is used to maintain the minimum temperature of the coolant after the gas and firewood have run out. Operation in anti-freezing mode is allowed. The electric heating element maintains a minimum temperature in the heating system, preventing freezing of the water circuit.
Some universal heating boilers - gas, firewood, electricity, use the principle of gas generation in their work, which increases the autonomous operation time to 6-12 hours, from one bookmark of logs.
Price range
Average prices of boilers Ochag are in the conventional range of 12-20 thousand rubles. Before buying, you should clarify what additional devices and devices will be needed for the normal operation of the boiler itself and the entire system as a whole.
In addition, you will need to conclude a warranty agreement in order to be able to urgently restore the system to work.
Boiler device
In general, he arranged in the same way as usual... But there are some peculiarities associated with the use of multiple resources.
Boiler included in the hot water heating system... Solid or liquid fuels are burned by heating the water in the heat exchanger. It moves through the pipes to the radiators, where it gives off heat. Then the cooled liquid returns to the heat exchanger.
Photo 2. Internal structure of a combi boiler: the possibility of heating with wood or gas is shown.
With electricity the heating principle is slightly different. Used heating elementthat heats the water in the tank.
What elements are included in the design and how do they interact?
The main parts of the boiler are as follows:
- firebox;
- burner;
- Heating element;
- heat exchanger;
- automation;
- body;
- outlet branch pipe.
Sometimes there is one combustion chamber capable of providing combustion two types of raw materials... In other cases, two are installed at once, for solid and liquid species.
Heat exchangeris usually done from pipes... Then, with the same volume, the surface area is larger, and the liquid heats up faster. It is located next to the fireboxusually top or bottom. And if there are two, the coil is between them. The pipes for connecting the piping system are connected to the heat exchanger.
Automatic control much makes it easy to use boiler. Maintaining the set temperature occurs without human intervention. It is measured by sensors. If necessary, the damper opens more or less. In this way, the flow of oxygen and the intensity of combustion are regulated. The heating power is also regulated by the heating element. If one of the raw materials is not available, the device will switch to another. The parameters are configured on the control panel. Some models have and Remote Control.
Housing boiler is manufactured made of steel or cast iron. For thermal insulation, it is made double. In more expensive models, noise insulation is also present.
Design features
The specificity of the boiler device is associated with the use of various heat sources and depends on the types of fuel. The following options are possible:
- Two combustion chambers instead of one.
- Combination furnaces and heating elements.
- Removable pellet hopper and an automatic feeding mechanism.
These features and lead to an increase in size boiler.
general information
Modern boilers operating on solid fuels have gone far from their "progenitors". Today, a boiler is a device that ensures long-term combustion of fuel by using the pyrolysis effect. Thanks to this, it was possible to significantly increase the efficiency of fuel technology.
In addition, modern boilers are equipped with a device for adjusting the heating power and combustion intensity. Thanks to this, the owners have the opportunity to choose the optimal temperature regime in the house, saving fuel.
Principle of operation
The boiler is divided into two parts:
- the upper compartment is used for stowing fuel (coal or firewood);
- the lower compartment is a combustion chamber into which air and gaseous products of the pyrolysis reaction are fed, passing in the upper chamber.
Fuel combustion takes place at extremely high temperatures, this process ensures the release of gas from the fossil fuel, as well as a large amount of heat.
