Long-burning wood-burning boilers are in demand among summer residents and owners of cottages intended for year-round use. Before installation, you should understand the features, pros and cons of this type heating a private house.
Long-term combustion boilers using wood do not require frequent maintenance, and the cost of each 1 kW/h. thermal energy is several times lower than when using liquid fuel or gas units.
A solid fuel wood boiler is well suited for homeowners who have the opportunity to purchase good quality firewood
In general, the operating mechanism is based on long-term smoldering of fuel due to limited air supply - as a result, the fuel lasts approximately 80% longer than during operation solid fuel boiler the so-called classical type.
Pros and cons of wood-burning boilers for long-burning fuel
Advantages:
- no need for frequent refueling - depending on the chosen model, you need to add firewood into the combustion chamber from once every 3-4 hours and up to 12 hours;
- possibility of application various types fuels and their combinations;
- In most cases, the boiler operates autonomously and does not require connection to other communications;
- relative cheapness of fuel.
Solid fuel boiler in a private house
Flaws:
- the cost is higher than classic boilers;
- due to the low calorific value of firewood, the efficiency is from 70 to 89%;
- There is no mechanism for regulating the temperature regime.
Also important disadvantage is the impossibility of work heating equipment without human intervention
Advice. Mainly purchased for dachas and private cottages wood boilers not with combustion chambers large sizes. Promote Heating efficiency possible by increasing combustion chamber, but at the same time the dimensions of the boiler itself will increase.
Varieties by mechanism of action
- Heating unit with extended firebox
The simplest and most common type wood heating. The main difference from standard solid fuel units is their elongated shape with an elongated firebox. Directly into the combustion chamber after ignition, air is supplied in a dosed manner, due to which the operating time on each load of firewood is significantly increased (up to 6–8 hours).
Solid fuel boiler with extended firebox
- Top burning model
Unlike standard wood-fired boilers, which are ignited from below, in the chambers of top-combustion boilers, fuel is burned under the influence of a burner moving from above and slowly descending down. - Pyrolysis boiler
The gas generator or pyrolysis unit has a more complex operating principle and design compared to the two previous models, due to which it can operate continuously for up to 12 hours on each fuel fill. In the combustion chamber, the wood does not burn in it, but smolders very slowly, in turn releasing gas. It is discharged into the lower chamber compartment, where it is burned under the forced supply of oxygen, releasing additional heat.
Top combustion solid fuel boiler
The most popular units for private properties
Different models of wood boilers differ from each other:
- dimensions of combustion chambers;
- type of construction;
- material of manufacture.
The heat exchanger is often made of steel or cast iron. At the same time, cast iron will last longer than steel, it takes a long time to cool down, but can collapse under sudden temperature changes. Steel is heat-resistant, but can be subject to corrosion and will last on average about 10–15 years.
For country heating Most often, simple single-circuit models are installed; for houses with year-round occupancy, it is rational to install a double-circuit boiler. In the latter case, one circuit will provide heating, while the second will provide hot water supply.
Diagram: device of a pyrolysis boiler
Each individual unit has its own special technical specifications, averaged data:
- power about 100 kW;
- coolant temperature at the outlet is 80 degrees, at the return - at least 50 degrees;
- working pressure on average 1 atm.;
- boiler weight up to 400 kg;
- Duration of operation on one load of fuel is 10-12 hours.
Operation of a pyrolysis boiler
Attention! When buying a heating boiler that runs on wood, you need to take into account that most units were originally designed to burn brown or hard coal. In their technical passports The power and burning time of one bookmark are indicated based on work on coal. Therefore, it is necessary to separately calculate the power and combustion time of the fuel if the heat generator runs on wood.
How to properly organize heating
In private cottages intended for year-round use, long-burning boilers equipped with heat exchangers are embedded in the heating system. The coolant carries thermal energy, obtained by burning wood, to radiators.
Attention! If in autonomous system used circulation pump, it is necessary to make sure that the boiler heat exchanger can withstand the operating pressure of the entire system.
IN small dachas for 1-2 rooms there is no need for a heating system autonomous type, it is more rational to use a convector oven of the “Buleryan” type. For models operating on the convection principle, the walls of the fireboxes consist of open metal tubes that are welded to each other in a vertical position.
House heating system using a solid fuel boiler
During the combustion of wood, heated air rises through the tubes due to the action of convection, and cold air comes in its place.
Fuel selection
You can place a long-burning wood-burning boiler both in the house and in an equipped boiler room or in a small separate extension to a private cottage. In this case, it will be necessary to allocate a separate place for fuel: wood, coal, peat, etc.
The most popular type of fuel is often waste from the wood processing industry. But this type fuel is low-calorie, so it is required high consumption.
Wood is the most popular type of fuel for a home boiler room
The choice and degree of moisture content of the raw material will directly determine its calorific value. The fuel with the highest productivity is dry firewood, the quality of which should ideally be the same high from purchase to purchase. Maximum length fuel - 40 cm.
Important installation features
The weight of wood-burning boilers reaches several hundred kilograms, so before installation you need to make sure that the floors can withstand the load. For durable floors cast iron will do product, in other cases it is worth considering the option of purchasing a steel boiler, which will weigh several times less.
At the place where the unit is planned to be installed, a concrete pad is usually installed (its thickness varies from 100 to 150 mm).
For the smooth operation of the boiler, its correct installation is very important.
IN non-volatile boilers so-called mechanical thermostats are used. If the model has a fan designed for forced air supply, as well as an electronic control system, then a power supply will be required.
It is important to take into account that during power outages, operation will be very difficult.
Conclusion
Long burning boilers deserve special attention when choosing heating equipment for private houses and cottages. The most effective are pyrolysis units that have the most high efficiency 97% and long term work without refueling.
Placing a solid fuel boiler
Before purchasing, you should also decide on the material of manufacture, the required volume of the firebox, prepare the boiler room or equip a place for the boiler in the house. Separately, you should take care of choosing high-quality fuel - dry firewood must be prepared in advance, and a separate place is allocated for its storage.

In conclusion, the video: how to choose a solid fuel boiler for a private home?
Do you think that when building a house, the owner thinks about what is the best solid fuel boiler, which one is better to choose for heating his home? It seems to me that after he has decided on the fuel, choosing a solid fuel boiler for him is the second most important issue.
It turns out that it is possible. After all, choosing a solid fuel boiler is a subjective thing. When a person chooses boiler equipment for himself, he does not need to convince anyone that he is right or provide compelling arguments in favor of this or that heat generator. He buys and that's it.
Takes the parameters he needs, for example:
- Availability of the specified type of fuel in its region.
- Budget for the purchase of a heat generator.
- Possibility of DIY installation.
- Warranty period from the manufacturer.
- Possibility to install a TT boiler without preliminary preparation into the boiler room.
A person compares ALL boilers and all types of fuel using these indicators. And it doesn’t matter to him that supposedly the pelletizer cannot be compared with each other. Oh, he's just comparing.
So why then ratings and correct comparisons of heat generator heat generators only within one type of fuel? And so that it would be. So that a person can receive not only subjective information from forums and reviews in the form of “good - bad”, but also be able to compare specific numbers for different heating equipment.
