A long-burning boiler is installed in large rooms and private houses where there is no connection to the gas main. It is used if it is impossible to install an electrical unit. In this case, there is no need for coordination with regulatory services or drawing up a plan for laying heating pipes outside the building.
Long-burning boilers are installed in private homes.
Features of long-burning solid fuel boilers
TT installations are made with a large capacity for firewood.
So that the combustion chamber can be loaded to the maximum, the door is located at the highest point of the housing.
Purpose of boilers
Prolonged combustion units are used for heating large areas and domestic buildings. 1 system is capable of providing heat to 2-3 buildings on the site.
What are the advantages
The device has the following advantages:
- long burning time, which ranges from 2 to 5 days (some devices support it up to 7 days);

Disadvantages of long-burning boilers
The devices have such disadvantages as:
- the need for strict adherence to safety rules during the installation phase and during operation of the device;
- fuel compliance with humidity and quality requirements;
- the need to connect automated equipment to the power grid;
- heavy weight of some models;
- labor costs when loading the tank;
- cost from 50,000 rubles;
- need for regular cleaning.
To store fuel, you need a separate area, protected from moisture. For some models, a boiler room is equipped.
Tips from the experts
The future owner of a solid fuel boiler should know the following before purchasing:
- What type of fuel will be easiest and most economical to purchase in your area of residence. This can be coal, peat, firewood, organic briquettes or pellets.
- Determine the required power of the equipment used to heat the building. In general, to heat every 10 square meters of area of a well-insulated house, 1 kW of boiler energy is required. The calculation should be performed with a small margin, since the efficiency of heat transfer gradually decreases over the years of operation.
- If you need not only to heat the building, but also to produce hot water for household needs, the boiler you purchase must be a double-circuit one.
- The quality requirements for a boiler used in a cottage with continuous residence must be higher than for a country house visited periodically.
Principle of operation
Long-burning solid fuel devices burn wood from top to bottom. The reservoir is filled completely. For ignition, small wood chips are used, for which a small space is left at the door. At this stage, air enters the chamber.
Construction of a solid fuel boiler.
When fuel is occupied, oxygen access is minimized. The firewood begins to smolder. The top layer burns first, and then the bottom. During thermal decomposition, the fuel releases large amounts of gases. They have a high energy potential and go into an afterburning chamber, where they burn out completely. If you analyze the operating principle of a long-burning solid fuel boiler, you can correct the shortcomings that arise.
As a result, heat is released. The fuel itself is processed into fine ash.
Types of long-burning TT boilers
Its efficiency and financial costs depend on the type of heating equipment.
By download method
Devices are:
- Traditional. Loading firewood, as well as monitoring the combustion process, is carried out manually. This design does not depend on the electrical network, is cheap and reliable. The disadvantage of the product is the need for constant supervision and care.
- Semi-automatic. Firewood is loaded into the chamber by hand, and the combustion process is controlled automatically. In such models it is possible to control the air supply and coolant temperature. The boiler automation operates from the mains. If there is no power, the equipment will not be able to perform its functions.
- Automatic. All operations are carried out without human intervention. The unit is equipped with a hopper that is filled with fuel. Then, using a screw mechanism, it is sent to the combustion chamber as needed. The equipment is characterized by high efficiency and the ability to fine-tune functions. But the device costs more, is dependent on power supply and is difficult to operate.
In traditional boilers, wood is loaded manually.
Traditional loading is suitable for systems with natural coolant circulation.
By fuel type
Based on the type of combustible material used, the following types of devices are distinguished:
- wood;
- coal;
- peat;
- pellet
There are different types of fuel for boilers.
The latter are the most expensive, but environmentally friendly and economical.
According to the principle of combustion
Based on the characteristics of fuel combustion, the following types of units are distinguished:
- Pyrolysis. These are modern boilers with 2 combustion chambers. In one of them, the firewood smolders and releases gas, which enters the second compartment, mixes with oxygen and burns. As a result, little soot is released.
- With upper localization of the combustion compartment. The presented devices are easy to maintain. Some models are equipped with automatic control.
The second equipment option requires careful selection of fuel.
Types of boilers by type of fuel bunker
There are two types of loading devices: built-in fuel hopper and mechanized storage. The battery life and the area occupied by the boiler installation depend on which of them the unit is equipped with.
Built-in fuel hopper
Models with a built-in loading device are equipped with a container for solid fuel, which is located on top or on the side of the main chamber of the boiler. The advantage of this design is the relative compactness of the heating installation. However, in terms of battery life, models with a built-in bunker are inferior to units with mechanized fuel storage.
Mechanized fuel storage
Here, a separate room or part of a room with a connected flammable material supply system acts as a loading device. The volume of such storage is enough to accommodate a year's supply of fuel.
The models are distinguished by a complex electronic automatic control system, which fully regulates all work processes, as well as the presence of a remote control unit.
Criteria for choosing a long-burning boiler
A correctly purchased and installed unit will increase the efficiency of the heating system.
Construction type
When viewing suitable models, pay attention to the type of loading of flammable material: front or top. They can also be atmospheric (with natural draft) and supercharged (with a fan forcing air).
When choosing a boiler, pay attention to the type of design.
Boiler cost
The price of the unit depends on its functionality and manufacturer:
- German and Czech equipment is the most expensive. For it you will have to pay from 150 thousand rubles.
- Average price for Latvian and Polish equipment. Its cost is from 100 thousand rubles.
- Russian equipment can be purchased for 50-60 thousand rubles. At the same time, it is adapted to the conditions of climatic zones and is unpretentious to the quality of combustible material.
Type of fuel consumed
For a private home you can use the following boilers:
- Coal. When purchasing fuel, pay attention to its grade and fraction. Requirements for flammable material are specified in the instructions for using the equipment. The coal layer should not exceed 20 cm. There are models that operate on peat.
- Wood-burning. Pine, birch and other types of wood are suitable for them. An important condition for using such fuel is its moisture level. The higher it is, the faster the equipment will fail.
- Pellet. They are characterized by high levels of efficiency and productivity.
Home installations can operate on briquettes made from peat and agricultural waste.
Dimensions
Super long-burning boilers are large in size and require a separate boiler room.
Long-burning boilers have large dimensions.
Power
This parameter depends on the heated area. For 100 m², 10 kW of power is required. After making the calculations, another 10% is added to the result in case of severe frosts. For individual heating systems, devices up to 35 kW are suitable.
For houses with several apartments and industrial buildings, a unit of 100 kW is required. The performance of the boiler is also affected by the calorie content of the fuel.
Chamber volume
There is an indicator depending on the ratio of the device’s power and the size of the loading compartment. A coefficient of 3.5 to 5 l/kW is sufficient. The higher the final figure, the less often you will have to lay firewood.
Efficiency
The efficiency depends on the design features of the equipment, the type of fuel used, and the presence of additional functions. The higher this indicator, the better. The numbers should range between 85-95%.
Efficiency depends on the design of the boiler.
Heat exchanger material
The heat exchanger is made of the following materials:
- Become. Special heat-resistant grades of metal are used for production. These products have low inertia and differ in design solutions. They are easy to maintain and resistant to mechanical damage. The steel heat exchanger has a small mass. The disadvantages of the device are its short service life and susceptibility to rusting.
- Cast iron. A device of this type consists of 2-3 sections. They are connected to each other by threaded elements. The metal is resistant to corrosion and mechanical damage. Cast iron can be repaired. However, it is destroyed under the influence of temperature changes, weighs a lot, and provides lower efficiency.
There are devices with copper heat exchangers. This metal conducts heat well, and therefore increases the efficiency of the heater.

Fuel requirements
Although such long-lasting boilers can be heated with wood or wood pellets, the duration of their combustion will not be 7 days, but depending on the characteristics of the fuel – 12-30 hours. High-quality pellets can provide heat generation for a maximum of 72 hours, i.e. up to 3 days.
To ensure a combustion duration of up to 7 days, it is necessary to use coal. The optimal price-quality ratio is coal. Anthracite has the greatest heat transfer, but the cost of such coal is 8000-8500 rubles. per ton, which is not cheap. Charcoal (especially from hard wood - grade A) also has excellent heat transfer and burning duration.
The worst option is the common and most affordable brown coal, which burns in 3-4 days at best and has a much higher ash content compared to other varieties.
In addition, it is better to burn with low-caking (type 31 or 32) and low-ash (up to 15%) coal to avoid the appearance of excess “garbage” and a decrease in efficiency.

Customer Reviews
Alisher B.
Teplodar Cooper Expert-15
Advantages: Electronic control. Quiet operation. Weekly timer Connection of an external thermostat Burner modulation Built-in expansion tank Possibility of using non-freezing coolant Disadvantages: Operation of an anti-freeze system. The manufacturer cannot provide information on the OpenTherm interface, which is declared in this boiler, and the equipment compatible with it. Comment: I was a little disappointed by the breakdown. Immediately after the initial startup, the system board needed to be replaced - the system did not see that the burner was lit. But the issue was resolved directly with the manufacturer. I received the new fee by mail 4 days after applying. I installed it myself. Everything has been working fine for a year now. The service is fine. Incomprehensible anti-freeze system. The pump turns on at +8, turns off at +12, and the burner turns on at +5. And if the temperature falls into the region of +10, then the circulation pump works for days. And if non-freezing coolant is filled in, then this system is not needed at all.
Pavel Z.
ZOTA Topol32VK 32 kW
Advantages: Well assembled, affordable price, easy to load Disadvantages: Not very convenient to clean Comment: I took it to the dacha, so I was looking for an inexpensive coal/wood burning model. Of this price range, I liked Lemax more than others - you can load it from above, and not push it through the door. I had experience with a side-loading boiler, but I didn’t like it. There is more fuss, you also have to push the coal to the sides through the door, otherwise no matter how you load it, there is really no heat. It’s much easier with top loading, and it’s more convenient to burn the same wood. It heats normally, the metal is thick. Cleaning, however, is inconvenient - through the very bottom. If the coal is of low quality, then it’s still a pleasure. Although I won’t say that there is so much dirt left on the coal. Well, I definitely liked the boiler; it heats up the dacha quickly.
Nikolay V.
ZOTA Topol32VK 32 kW
Advantages: Reliability, functionality Disadvantages: Noisy Comment: Last year we selected a gas boiler for heating. We looked at more than one option and chose the Lemax Premium-30V boiler. We consulted with neighbors and gas workers. We looked on the Internet. Lemax is produced in Russia. This means they are adapted to our Russian realities, unlike imported ones. This is a floor-standing, double-circuit boiler with an open combustion chamber; combustion products are removed naturally through the chimney. It will heat the house and heat the water. Electronic control. The quality is top notch. This is confirmed by those who already use such boilers and those who service them. The boilers are reliable, and if something happens, they are repairable. Spare parts are always available and at low prices compared to imported ones. We ourselves were convinced of the quality of the boiler. Last winter, and it was frosty, he proved himself to be the best.
Kirill M.
Teplodar Cooper Expert-15
Pros: Excellent boiler. There are commissioning features. Reading the manual!!! By default, the turbo water heating mode is set, which is needed if you have a long distance from the boiler to the point of water consumption; the water is heated to 70 degrees immediately. If you have a bathroom behind a wall, it is better to turn off this mode in the settings. In the second mode, the boiler is set to maximum heating output, so if you place the boiler in a small room, it is better to also reduce the heating. This is important, and then you will be happy and there will be no problems with operation. And also, if there are problems with water pressure, then install a mixer with separate valves (do not install joysticks), but this applies to any boilers.
Roman Strukov
ZOTA Topol-16VK 16 kW
Advantages: a closed combustion chamber in itself is already good, especially if the room where the boiler is located is small. Another big plus is ease of use; a more or less modern person will find a common language with technology quickly enough, especially if he can read. Disadvantages: the price for additional upgrades and repairs is unrealistic; if you don’t have a friend who can get parts at cost, then any repair, even the smallest one, will cost you at least 5 thousand. again, provided that you purchased a “purebred” German. According to the same familiar service technician, the CIS countries and Middle East Asia have begun to make replica boilers from cheaper alloys, and companies that have received sales certificates from officials are starting to buy replicas and sell them at the price of the original. so for repairs, one small plastic part cost 3 thousand, add here a call to a specialist, his work and diagnostics, you will get a price higher than the indicated one... Comment: when considering boiler options and prices, be sure to calculate the cost of additional equipment for normal operation of the boiler. this is a chimney, it is purchased separately, and a power stabilizer, it equalizes the supply of electricity; if the boiler heats the house, then a stabilizer is required. Also, if the area is large and the house has several floors, you will need a pump and an expansion barrel; the boiler has these elements, but due to ergonomics they are of small volume and capabilities. For heating systems, automatic air exhaust is required so that the air lock does not reach the boiler, otherwise, at best, you will get away with a program error. pipes for heating of at least 20mm INNER diameter, for supplying hot water to taps with no MORE than 15mm internal diameter, specifically for this boiler, this is according to a specialist with extensive experience and well-deserved respect.
Anatoly
NMK Magnum KDG 15 TE
Pros: Quite simple, easy to understand. The camera is closed. Powerful for its size, definitely enough for my purposes (heating a one-room apartment) reliable. Disadvantages: normal domestic boiler, simple without bells and whistles, not the most expensive. Comment: I also have an apartment with individual heating, I was looking for a boiler specifically from a growing manufacturer, because I understood that foreign ones were not so tailored to our market, my mother had an Italian one for fifty dollars and at home there was a wild oak as soon as there was more outside the window - 10.. that’s actually why I thought, well, I’ll look for our people. I ended up taking this model from Lemax and didn’t regret it, it’s a good boiler, easy to operate. In terms of safety, they seem to be praised, with overheating protection and gas control as standard. In short, my head doesn't hurt anymore
Alexander Linev
NMK Magnum KDG 15 TE
Advantages: Economical to operate, easy to operate. Low cost. Disadvantages: I didn’t see them here Comment: I chose the boiler based on its characteristics. It is completely enough for my country house. The manufacturer is well-known, the warranty is good. There are no complaints about the build quality, everything is reliable, nothing hangs loose. Its main advantage is that it is economical and gas consumption is not too high. There were no problems with installation and connection. There was no need to make additional fastenings to the wall because it is floor-mounted - it’s convenient. It looks very simple, nothing extra, just a temperature controller and a thermometer. It's easy to monitor the work. the price is low for this type of boiler, considering the area it heats. In general, the purchase is necessary!
Ivan Chirkov
ZOTA Topol-16VK 16 kW
Advantages: Domestic product. There are no problems with the service and sound. Disadvantages: There was condensation. Comment: I installed Lemax Premium at the end of last summer. Just a couple of years ago I wouldn’t have even looked at it. Before it there was an expensive but popular unit. And I understand very well those who say that Europe is doing great. Yes it is. And when everything is fine with your expensive boiler, you live and don’t give a damn. But as soon as problems appear, that’s it. Do you know how much it costs to change a heat exchanger or automatic ignition? Yes, it’s easier to install a new boiler. I had no illusions about Lemax, but at least I knew that if something happened they would help me, our service technicians know our products better and spare parts are always within easy reach. That's why I took the course that it would be cheaper to maintain. There is little to say about the boiler itself yet. It works and doesn't make any noise. At first I was confused by the condensation that appears when it warms up to 50 degrees. But the support service assured that this was normal for such a temperature, and I myself later saw in the passport that this was written. Pah-pah, let it continue to work.

Advantages: safe to operate, high efficiency, consumes gas in moderate quantities, reliable, well-made housing, easy to operate, easy to set operating mode, stable operation, adequate affordable price for the boiler Disadvantages: periodically you need to monitor the condition of consumable parts Comment: The boiler has been in operation for about three years, the boiler has shown itself only on the good side. A separate extension is not needed for it, it is not picky in installation, the main thing is to comply with the requirements for the installation of the boiler itself and the chimney. There is protection against overheating, this is a plus for safety, and there is also protection against soot formation.
Alexey Shch.
Bourgeois-K MODERN-32
Experience of use: several months Advantages: silent, powerful, easy to operate, does not depend on the power supply. Disadvantages: none Comment: Last year I opted for the Lemax Premium-10 boiler, but did not buy it because... the house was under construction. This year the construction was completed and all the finishing work was completed, and it was necessary to start the heating system so that the renovation could be completed and the move in. The boiler is excellent, silent, powerful, easy to operate, and does not depend on the electrical network. It suits me and I made the right choice.
Alexey B.
Bourgeois-K MODERN-32
Advantages: silent, economical, reliable, works without failures. Disadvantages: I didn’t find any during the heating season. Comment: When I renovated the house and completely changed the heating pipes and radiators, the next step was to buy a suitable boiler. A mechanic I know recommended buying Lemax. That's exactly what I did. I took Lemax Premium 10, designed for a heated area of 100 square meters. My house is small, only 70 square meters, so I also managed to spare. The boiler is good, works silently and without failures, is powerful and economical.
Valentin Ya.
Teplodar Cooper Expert-22
Advantages: good price, easy to install, mechanical adjustment, no electronics Disadvantages: It turned out to be rather weak (however, this is my miscalculation) Comment: Assembled with high quality. As installed a year and a half ago, it did not cause any problems. The design is simple but reliable - no fancy electronics, it works without being connected to an outlet. The ignition is well done. Warms up quickly. But last winter it was a little cold, I saved in vain - I should have added Lemax’s “Patriot 20” to the same one, it would have been warmer with it. 12.5 kilowatts is still not for my area, and the walls don’t have proper thermal insulation. It's a shame, the boiler itself is excellent.
