Review of domestically produced boilers
The growth in demand for solid fuel boilers was facilitated by the development of pellet production in Russia. Pellet granules, made from pressed wood chips, are a cylinder with a diameter of 6 to 10 mm and a length of up to 30 mm.
Thanks to grinding and pressing (the press develops a pressure of up to 300 atm) of the source material, pellets with the same mass occupy a much smaller volume than conventional fuel and burn with virtually no residue. And the granular format of this fuel makes it possible to automatically supply it through screw and piston feeders. At the same time, the volumetric fuel consumption is so low that one refueling of a standard size bunker is enough for a whole week of operation of the unit.
Solid fuel boiler START
- The most popular Russian-made pellet solid fuel heating boiler is manufactured. A characteristic “trick” of this manufacturer is the bright orange color of the body, for which people began to call the boiler “orange”. The unit is equipped with an electronic control system and is even equipped with a display that displays information about the operating mode and condition of the boiler.
- Start boilers are also designed for the use of pellets, but the design of these units allows the use of any other type of solid fuel. While other solid fuel boilers made in Russia are mostly loaded from above, in “Starts” the feeding conveyor is located horizontally. This design is more tolerant of fuel with an uneven fraction and can work with it stably, without blockages and jamming.
- Boilers of the “Elephant” Trademark, which are also of domestic origin, have many advantages. The main one can be considered a surprisingly high efficiency - in the range of 95% - 97%. This efficiency was achieved thanks to the special design of the firebox and the surrounding water jacket. The service life declared by the manufacturer is 25 years.
- Russian-made pyrolysis boilers, also called gas generator or long-burning boilers, are also well represented on the market. Given the limited scope of the article, we will only talk about a few brands.
Solid fuel boiler for heating a private house, which one is better to choose? Rating 2022
When choosing solid fuel boilers, you should pay attention to the following criteria:
Be sure to look at the power of the devices. It is generally accepted that 1 kW of power is needed to heat 10 kW
m. It is important to consider what fuel the devices operate on. This can be firewood, peat, anthracite and other types of fuel. The battery must be energy efficient; we pay attention to energy consumption and energy independence. It is better if the devices have a high efficiency - from 85 percent. This is a very important indicator when choosing a solid fuel boiler for heating a private home. We check the ventilation system; if the draft is low, we purchase additional equipment.
Siberia
The main difference between solid fuel boilers from the Siberia company and others is the presence of a steel hob in some models. Therefore, these units can be used not only for heating rooms, but also for cooking.
They operate on both wood and coal. The power of solid fuel boilers is up to 30 kW.
The Sibir company produces solid fuel boilers with a water circuit, which means that if you want to supply hot water, you can get such a device.

Device Features
Solid fuel boilers have such functional systems as:
- temperature control;
- smoke removal;
- coolant turnover;
- firebox
The supplied fuel burns in the firebox. This causes its walls to heat up and transfer high temperature to the water circulating through the water jacket. There are pyrolysis and classic boilers. In classic ones, the fuel simply burns, releasing gas. In pyrolysis, fuel and released gas are burned in different systems. This increases power, efficiency and reduces chimney requirements.
However, pyrolysis equipment is demanding on the level of fuel moisture - no more than 20%. The owner of the boiler must have a supply of firewood at all times, which has been drying for at least a year.
The firebox has double walls. The coolant is poured between these walls. As a rule, water is used. Sometimes water is mixed with antifreeze. Such equipment is most common in central Russia.
After the coolant has heated up, it passes into the heat pipe. The water then passes through the pipes, heating the room, and returns to the boiler. To speed up the circulation of the carrier, special pumps are used. Smoke removal equipment looks like pipes with a heat insulator extending from the boiler to the street. In some models they are equipped with forced ventilation systems.
Water machines require careful attention to temperature. To avoid an accident, you need to make sure that the water does not boil. Fuel combustion can be stopped by reducing the intensity. To protect the system, cooling-type heat exchangers are used. Water is supplied to them directly from the water supply. In case of water supply interruption, you need to have a spare container of cold water. To shut off the flow of overheated water, a special shut-off valve is used.

- build quality;
- smokes, overheats, and clogs the chimney with tar if installed and used incorrectly.
If you decide to buy such a boiler, it is better to call professionals to install it, who will provide a guarantee to eliminate installation defects if they are identified. Otherwise, you risk getting a lot of problems due to the design features of the device. For beginners, I recommend a regular solid fuel boiler, for example, ZOTA Topol M 14 or more powerful models (for example, “Topol M”) for heating a large area.
Zota
Zota solid fuel boilers are produced in Krasnoyarsk. The products of the Krasnoyarsk plant are familiar to customers with brands such as Dymok and Zota Mix.
They have proven themselves well and users speak well of the quality of operation of such devices.
Fuel loading in these units can be carried out both vertically and horizontally, and they also have a power control panel.
Solid fuel boilers ZOTA "Dymok-M"
Main advantages:
- high efficiency - up to 80%;
- efficiency;
- you can change the fuel;
- equipped with electrical control of combustion temperature and power;
- high quality;
- affordable price.
All of the above advantages of the functioning of Zota boilers characterize the products of this company only on the positive side.
Parameters for choosing a solid fuel boiler
Efficiency
Power is valuable as a parameter only in relation to efficiency, and in this case it fluctuates widely and depends on the type of unit and combustion material.
1. Traditional devices have an efficiency of about 80%,
2. pyrolysis – approximately 90%,
3. long burning – about 85%.
Type of fuel
The type of fuel is of great importance, and it can be very diverse:
1. Coal;
2. Pellets;
3. Briquettes;
4. Firewood;
5. Coke;
6. Peat.
When burning fuel, ash is formed, which needs to be cleaned: from coal - every day; from wood - weekly; from briquette - monthly.
Heat exchangers of products are:
1. Cast iron;
2. Steel;
3. Copper.
Purpose
The devices are:
1. Single-circuit - designed exclusively for a heating system with the ability to connect an indirect heating boiler;
2. Double-circuit - designed for heating and hot water supply.
Electricity dependence
Devices are also divided according to the criterion of dependence on electricity. Models that operate without electronics, are loaded manually, and circulate water without a pump are considered autonomous.
