Accordingly, this type of equipment saves money well and allows you not to depend on a particular type of fuel and its presence or absence. If the main type of fuel runs out, the combined gas-solid fuel boiler will switch to the use of an auxiliary type of fuel.
Before purchasing a combi boiler "gas-solid fuel", you must consider the following:
- Combined units with a capacity of less than 40 kW are mounted in any room. Those larger than 40 kW require a separate space (boiler room).
- The boiler room will require an area of at least 12 m² with a height of at least 2.2 m.
- The floor and walls of the room must be lined ceramic tiles or plaster, that is, a material that does not burn.
- The room should be equipped with ventilation, as well as windows facing the street. The size of the windows must be calculated according to the capacity of the boiler.
- Where chimney floor slabs and roofing cake , fire-prevention cuts are installed, and the pipe is separated with a mineral sealant that does not burn.
- To increase the traction force, a deflector and a spark extinguisher are attached to the chimney head.
If you decide to connect a gas-solid fuel boiler to gas on the main, you must remember that the first “start-up” is carried out in the presence of an inspector gas service. He must also put a mark in the boiler document on putting it into operation.
gas firewood
The advantage of universal gas-firewood heating boilers lies in autonomy: smooth transition systems for burning wood in the absence of gas. Also, if desired, you can connect the structure, because the boilers are attached necessary connections and pipes.
Such universal boilers"Gas-firewood" can be single-circuit and double-circuit, so it will not be difficult to connect or heat water in a flowing way.
The disadvantages include large dimensions similar units. Most often they require a separate room for installation, and imply complicated service. Typically, such boilers are produced only on the floor type.
Combined boilers"gas-firewood" for the house implies increased requirements. The rules and regulations for operation are described in PPB, SNiP and SP.
The combined gas-firewood boiler for a private house includes the following elements:
- Furnace chamber. It is made from cast iron or steel. The boiler can be with one firebox or two (more convenient). In the double version, firewood is burned in the upper section, and firewood is installed in the lower section.
- Contours of hot water supply and heating. They are produced by companies specifically for heating, or for heating receiving hot water(two-circuit). DHW heating flow way.
The universal gas-firewood heating boiler assumes savings. This can be verified by looking at the following table.
High-quality wood and gas equipment is produced in Russia: Zota MIX, Kupper PRO (Teplodar), Karakan (STEN), PARTNER (KOSTER), STS (Steel Solid Fuel Systems). As well as foreign companies: Austria and Germany ("Wirbel"), Finnish concern "Jaspi" and others.
It should be noted that in foreign analogues, defects in the assembly and are less likely to be noticed. They boast reliability and quality. However, the domestic manufacturer is constantly improving in accordance with the wishes of customers.
Prices for combined heating boilers "wood-gas" depend on the country of manufacture, on the brand's popularity. For example, the company model "PARTNER" ("BONfire") will cost an average of 23 thousand rubles. Much will depend on the configuration, power and other indicators. But "Jaspi" will pull on all 130 thousand rubles. The takeoff is large, however, unlike the Finnish one, where everything is regulated by automation, in Russian counterpart all boiler settings will have to be carried out independently.
coal-gas
The universal gas-coal boiler is environmentally friendly and easy to maintain. However, when choosing this type of construction, you will have to constantly monitor the presence of solid fuel, because coal runs out quickly. If suddenly you come to the conclusion that "two in one" does not suit you, then you can always replace the burner - and the boiler will already work on natural gas.
Most often, a combined coal-gas boiler is allowed to be fired with firewood. For example, in technical specifications In the double-circuit model "Birch B" of the manufacturer "Atem" in the paragraph "fuel" is indicated "natural gas / coal" (see table). However, buyers use such a boiler for heating and firewood.

Do not forget to clean the boiler from time to time. During maintenance, it is necessary to remove accumulated wood dust, soot from the electric drive and moving elements.
What do you need to work on pellets?
To switch the boiler to fuel pellets, you need to install a pellet burner, which is connected to the fuel bunker. After all operations, the operation of the boiler is as follows:
- along the conveyor from the fuel bunker, the granules enter the burner;
- electric ignition occurs immediately by means of a piezoelectric element;
- a built-in fan is activated in the burner, which increases the pressure, and the combustion of the pellets occurs at a high temperature raised artificially.
Typically, gas-pellet boilers are made from cast iron, and due to their large dimensions and weight, the structure is placed on a concrete base.
What do you need to run on gas?
Pellet boilers with a gas burner are connected, first of all, to cylinders and. Such units are gaining popularity in the construction of houses and plots where natural gas is planned to be carried out soon.
To connect gas burner it is required, for starters, to close the unused firebox with an airtight hatch. Then in a specially designated gas equipment place you need to install a burner. After all, set the switch to gas consumption. Everything. Alteration took no more than 15 minutes of time.

Thus, combined boilers for heating a house - great option to get not only heat, but also cost savings. Since there is always a choice of fuel and its autonomous switching, in the absence of one specific type of fuel, your home will be heated at any time of the year. Combined solid fuel and gas boilers are reliability, high performance and versatility.
Let's start, of course, with maximum power. There is no need to think that if “10 kW / 100 m2” is written in the characteristics of the boiler, then it is small house enough to spare. First, the power of any solid fuel boiler it depends very much on the quality of the fuel, besides, the characteristics indicate for coal (heat transfer is highest on it). Try to add firewood - and it will immediately get colder at home, well, if the firewood also gets damp ... In addition, a boiler of greater power will also have a firebox bigger size- which means that it will have to be heated less often.
Generally, the need for frequent addition of fuel is a common problem with solid fuel boilers. There are several ways to solve:
- Bunker boilers- they automatically “feed” the firebox from a separate container (bunker). Such systems were developed primarily for pellets (fuel pellets), which are very convenient to feed with an auger, but now there are models that can work on coal.
- Boilers long burning have an increased loading volume, and the combustion process itself is not quite common there - the fuel burns from top to bottom. But they don't always have their own convenient features- we wrote about it higher in the rating.
But in any case, a "long-playing" boiler will become more complicated and more expensive, especially with a bunker. Then how about combined boiler? In them, heating is provided not only by the combustion of fuel, but also by the heating element installed inside - if the boiler goes out, the electricity will continue to maintain at least some temperature. It is convenient to leave such boilers for the night - you won’t wake up in the morning, feeling that the tooth does not fall on the tooth. Often, such boilers are also offered retrofit kits for gas or diesel fuel. Some models even initially provide for automatic switching to liquid or gaseous fuels if there is no fire in the furnace. In general, this option is interesting, if only because when it becomes possible to connect the house to gas, you will not have to change the boiler, buy a new one, redo the connection: you can simply put the gas burner on the old one.
Important point - heat exchanger design. Perfect option- cast iron: a thick-walled monolithic heat exchanger, if the manufacturer does not "miss" the shells and microcracks in the casting, it will be truly eternal, moreover, it will withstand high blood pressure no problem. But such a boiler will be both more expensive (you may not fit into the budget), and heavier (the question of the strength of the floor, you may have to strengthen it). At steel heat exchangers there is an inevitable risk of weld leakage, and the walls are usually thinner. Therefore, it is worth at least taking a heavier boiler, and look at the reviews on a specific model before buying - however, the reviews themselves have been buying for a long time ... So it’s better to choose a solid fuel one on the forums, and not on popular sites for reviews that occupied paid praise.
The heating system is one of the integral communications of the building. And here progress also does not stand still: every year manufacturers delight with new units. To make a good choice, it must be taken into account that each solid fuel boiler is designed for a certain power and, accordingly, may have a limit on the size of the heating area. The efficiency of the device and the type of control also matter, for example, the presence of an automatic ignition function will greatly simplify operation.

Solid fuel boilers are designed for space heating. It should be noted right away that the most convenient and cheapest type of heating in private homes is precisely gas heating. But since there are many regions in which natural gas is not available, a solid fuel boiler is the most economical and convenient alternative.
Also, it is important to note: do not confuse a long-burning solid fuel boiler with solid fuel stove prolonged burning. Although they are similar in principle and appearance, they are completely different things. The boiler is intended for installation of a water heating system, while the furnace is intended for air heating.
There are several main types of solid fuel boilers:
- Drovyanoy;
- Carbonic;
- pellet;
- Combined.
In each of these points, there are many types of aggregates. In order to commit right choice boiler, you need to decide on the specific goals assigned to the unit.
First, we will analyze the rating of types of solid fuel boilers. The most popular is combined, since both wood and coal can serve as fuel. The use of construction waste (wood cuttings) is allowed, while the efficiency is significantly reduced. It is also possible to install a gas burner or pellet fittings.
Coal-fired boilers can also be called combined, with their help it is also possible to heat the room not only with coal. But the shape of the fuel compartment, the dimensions of the furnace door are designed specifically for coal or anthracite, and the use of another type of fuel is difficult.
Wood unit. Only firewood can serve as fuel for this type of boilers, since the efficiency when using construction waste is significantly reduced, and coal combustion is unacceptable due to the inevitable deformation of the boiler walls.
The pellet boiler is the most complex view due to the complex design, many interconnected nodes, a specialized type of fuel. The fuel is biological pellets made from peat, wood waste or agricultural waste. The use of firewood or coal is unacceptable.
Another important point is the combination of the main characteristics of all types of boilers:
- power;
- dimensions;
- price;
- profitability;
- pressure;
- combustion time of one load;
- environmental friendliness;
- complexity of service and connection.
Manufacturers and sales managers often attribute all these characteristics to one boiler, but the combination of all the above points in one boiler is impossible. For example, high efficiency and profitability are incompatible, since in order to increase efficiency consumption fuel rises. The ease of maintenance and cleaning of the boiler cannot be combined with the long burning time of one fuel load, since in the case of smoldering fuel, and not intense combustion, a large number of resins. Resin settles on the walls of the boiler and chimney, which leads to a possible fire in the chimney. The point of environmental friendliness is possible only with a large injection of oxygen in the fuel compartment, which increases the rate of fuel combustion. That is, when choosing a boiler, you should decide on the characteristics that are most important to you.
The most important point is financial opportunities. If you have finances that allow you to purchase expensive equipment, you should stop at purchasing a foreign boiler, which includes all the necessary components of a reliable, durable and safe heating system.
When financial resources are limited, suitable option purchases of more affordable and less user-friendly domestic equipment.
Special mention should be made pyrolysis boilers. Manufacturers of these boilers attribute almost magical properties to them, declaring almost 100% efficiency, since there is no ash left in the ash pan at all, and the temperature of the exhaust gases at the outlet is 120 - 150 degrees. But since manufacturers do not explain the real reasons for these factors, pyrolysis boilers are advertised as the most environmentally friendly and productive.
Delving into this topic, consider what pyrolysis is. Pyrolysis in boilers is the ignition of exhaust gases during high temperatures: the smoke emitted during combustion in a conventional stove ignites in the boiler, and if you increase the draft in the stove when burning dry wood, a pyrolysis process is observed in an ordinary home stove.
The device of pyrolysis boilers. The combustion process in these units occurs from top to bottom by blowing air with a fan, that is, the air is directed towards the ash pan, which explains the absence of ash in the ash pan, it is simply blown away, and it is removed through the chimney. Manufacturers explain the absence of ash by the fact that the fuel burns completely, leaving no waste. Conclusion: pyrolysis boilers are a frank pumping out of money. Boilers naturally work and perform the functions assigned to them, but they are extremely expensive in price and maintenance.
Popularity rating of domestic and foreign boilers
The domestic market is dominated by such brands of foreign companies producing boilers:
- BUDERUS

- Teplodar
- Geyser
- Siberia - Gefest
When choosing a boiler for specific purposes, it can be the main heating system or alternative heating. Connected warm floors or water heating system. You can purchase a boiler from any of the above manufacturers. The range of each company has big variety units for any specific occasion.
How to calculate the power and characteristics of the boiler?
The calculation of the boiler power is calculated on average 1 kW per 10 m 2. With a room quadrature of 100 m 2, the boiler power will be 10 kW. These calculations are inaccurate because climatic conditions differ in different regions countries. You should also take into account the heat loss of the building, the insulation of walls, windows, doors. For the southern regions 0.8 - 1 kW per 10m 2, for middle lane 1 -1.5 kW per 10 m 2. For harsh northern regions 1.5 - 2.0 kW per 10 m 2. In the presence of warm floors, the boiler power increases and is calculated with the help of specialists, based on a specific case. Also, each additional consumable node increases the number of kW of power.
It should be noted that when choosing a solid fuel unit, it is necessary to take into account the energy dependence of the boiler, for example, the presence electric hair dryer or a heating element that heats the air in the boiler. If there is a power outage in your area, you will need to purchase a powerful uninterruptible power supply or a generator of sufficient power.
Another important attribute of the heating system of a solid fuel boiler is a buffer tank or a heat accumulator. These attributes will be needed by owners of houses with a large quadrature or multi-storey cottages. In such cases, without using buffer tank or heat accumulator fuel consumption increases. The dimensions of the boiler and its auxiliary units require a separate room. It is convenient to place them in basements or semi-basements. In addition, fire protection requirements also require the location of the heating unit in separate room. This room is in without fail must be ventilated to ensure sufficient air flow. No ventilation staff fire brigade have the right to impose a fine or prohibit the operation of the boiler.
You should also focus on adjusting the draft, the intensity of the air supply to the combustion chamber during the operation of wood-fired boilers. On the one hand, when the thrust is reduced, the fuel does not burn intensively, but gradually smolders. This naturally increases the burning time of firewood, reducing the cost of funds for the further purchase of fuel. But such pluses entail no less big minuses, since the combustion temperature drops significantly, which leads to very rapid clogging of the chimney and the inside of the boiler, that is, wood soot in the form of resin settles on the walls, which is very difficult to remove. And the time between cleaning the boiler and the chimney is significantly reduced, and this process is very complicated, unpleasant and “dirty”. Such problems are inherent in relatively inexpensive, mechanical units that are not stuffed with electronics, which itself calculates the amount of air supplied to the combustion chamber and the intensity of combustion.
