TOP 10 best long-burning solid fuel boilers for home heating: rating 2021-2022 and review of models with a water circuit and wood burning

To provide warmth in your home or country house, your own autonomous heating system is installed all year round. A long-burning solid fuel boiler (TCDG) can be an effective source of thermal energy . It is capable of operating for a long time on one load of fuel, which is facilitated by special technology.

Such equipment from leading domestic and foreign manufacturers is widely represented on the Russian market.

The question of how to choose the optimal model deserves special attention.

Rating of the TOP 10 best long-burning solid fuel boilers for 2021-2022

Long-burning solid fuel boilers are becoming indispensable in regions where there is no need to think about natural gas yet. They have proven to be very effective.

You can choose a model for a specific fuel type or choose a universal model. When choosing, you should take into account the main criteria.

The rating of the best models allows you to choose the best option.

Week "KO-90"

It is considered an ideal option for private homes. “Nedelka” is capable of heating up to four hundred square meters, and works for a whole week on one load.

Interestingly, the disadvantages are a continuation of the advantages of the vice-champion among solid fuel boilers.

Thus, the large weight and dimensions of the installation (minus) make it reliable and safe (plus).

The same can be said about condensate - its presence is a minus, but at the same time an indicator of a high efficiency.

What to look for when choosing?

When choosing a TKDG, the main attention should be paid to the following characteristics:

• Type of fuel . The units can be designed for a specific fuel or be universal. Main options: coal, firewood, peat, pellets.
• Boiler power . It determines the heated area. For domestic needs, usually does not exceed 100 kW.
• Number of circuits : single-circuit or double-circuit.
• Loading chamber volume . The duration of operation without new fuel loading depends on it.
• Cost-effectiveness , i.e. fuel consumption. The main indicator is efficiency.
• Durability or service life.
• Control systems : electronic or mechanical.
• Safety . Critical protection systems must be provided.
• Price.

You should also pay attention to the material of the body and combustion chamber, loading method (manual, automatic, semi-automatic), volatility, weight and dimensions.

• low fuel consumption;
• presence of a fire damper;
• complete safety.

The only drawback of the device is its high cost.

Operating principle of TKDG

Long-term combustion in a TKDG furnace can be ensured in 2 ways:

• Top combustion principle . In the combustion chamber, the fuel does not burn, but smolders with limited access to oxygen. The cylindrical firebox is located at the top of the unit and has a cylindrical shape. The gas released during smoldering enters the afterburning chamber, where a supply of atmospheric oxygen is ensured for its complete combustion. As a result, almost complete combustion of the fuel occurs with the active release of thermal energy.
• Pyrolysis principle . The combustion chamber is located at the bottom. Active smoldering of fuel also occurs here with limited access to oxygen. The combustible gas rises up and reaches the second chamber, where, enriched with oxygen, it burns completely.

Thus, the duration of combustion is ensured by the two-chamber design of the unit, when the fuel slowly smolderes in the firebox, and the released combustible gases burn in the second chamber.

Advantages of the boilers under consideration:

• high efficiency exceeding 90%;
• accessible and fairly cheap fuel;
• ease of installation, management and operation;
• almost complete combustion of combustion products;
• increased durability;
• affordable price.

Some disadvantages of TKDG should also be noted:

• the need for a separate room for installation;
• the need for periodic ash removal;
• arrangement of a storage facility for fuel supplies.

In budget designs, fuel is loaded manually, which can also be attributed to the disadvantages of such equipment.

Water circuit

To ensure autonomous hot water supply, in addition to the heating system, TKDG with a water circuit or double-circuit boilers are installed. Such units have 2 independent circuits for water circulation. An additional heat exchanger acts as a boiler and is intended only for heating water.

If the TKDG is connected to the water supply network, then water circulation through both circuits is ensured without forced supply, i.e. due to pressure in the water supply. When there is no centralized coolant supply, a storage tank is needed. It contains the necessary supply of water to meet demand.

The tank is usually installed above the boiler. A number of unit models have a built-in expansion tank. Forced water supply is provided by a circulation pump.

ZOTA Yenisei 12

The deep firebox allows the use of wood material up to sixty centimeters long. Tightly fitting doors prevent combustion products from entering the room.

How is the boiler power selected?

Accurate calculation of the required boiler power for heating a house is quite complicated. A simple technique is usually used: to heat an area of ​​10 m2, 1 kW of thermal energy is needed.

For unforeseen cases, a reserve of 10-15% of power is created. When using a water circuit or installing an additional boiler, additional energy of about 25-30% is required.

Climatic conditions make their own adjustments. In cold regions, where the air temperature can drop below minus 30 degrees, TKDG is selected at the rate of 1.6-2 kW per 10 m2 of room area. For the southern regions of the country, the requirement can be reduced: 0.8-0.9 kW per 10 m2.

EVAN WARMOS TT-18

The unit heats more than a hundred square meters. It is used for heating both residential and industrial facilities. The only condition for effective operation is the presence of ventilation.
