How to choose a solid fuel boiler for long burning: ranking of the best, customer reviews

Especially for you, we have performed an analysis and compiled a rating of solid fuel boilers for long-term combustion. Data taken from the Internet sales market among the most popular Russian resources and electronic catalogs of climate technology for heating a private home, and tried to understand that, which are modern solid fuel boilers of long combustion, what is the difference between them and what are the advantages, and shortcomings.

To answer the question "How to choose a solid fuel long-burning boiler for the home?"- Let's start with that, what they are and what are their differences. What is hidden by definition - long-burning boilers, what is their difference from other solid fuel boilers installations?

Features of long-burning boilers

The first and most important fundamental difference is the method of fuel combustion. In these units, the technology of the combustion process differs significantly from the traditional classic scheme "bottom - up", as is customary in conventional furnaces and furnaces, and which ignites the entire portion of the fuel at once. In this case, everything happens exactly the opposite - "top - down", like a candle. A sustainable effect is achieved thanks to the telescopic design of the air flow distributor, which under the action of its own gravity presses on the flame and gradually shifts it down. As a result, the fuel slowly burns out in layers, along the entire height of the vertical combustion chamber starting from the upper level - the type of upper combustion boilers.

This design allows you to burn the material measured, evenly and better, increasing the efficiency and duration of one download. in addition, this feature allows: increase the service life of the unit, because the movement of the heat source in time reduces the "fatigue strength" of the steel heat exchanger compared to traditional furnaces, in which the cell is stationary and stationary; and completely abandon the use of additional heat accumulators.

Mechanical control of coolant temperature is carried out by a thermomechanical draft regulator (based on bimetal), which directly affects the air valve. Therefore, they can be used in systems, as with natural, and with forced circulation of the heat carrier.

And the second distinctive feature is their "unpretentiousness and omnipresence". And what is especially important in the heating system - the most economical fuel consumption. Example, to generate power to 20 kW, their performance is the type of fuel / one-time download, kg):

• firewood (? 50 kg);
• fuel briquettes - wood (? 110 kg) and peat (? 119 kg);
• coal - coal (? 145 kg) and anthracite (? 170 kg).

Due to specific design features - they are single-circuit, and have an efficiency of about 91-93%, one of the highest in its class. To completely burn a single bookmark of firewood, they need about 30 hours, and the amount of heat, released during the combustion of coal, enough for four days (for a private house with daily needs 150 kW / hour) depending on the temperature difference inside and outside the house. Their few drawbacks include only restrictions on the use of pellets, manual fuel loading and ash removal.

Yet, today solid fuel boilers are considered one of the most promising alternative sources of heating. Convincing evidence of this is the indicators of popularity ratings and the constant trend of growing interest in this segment of technology for heating a private home.
