Accumulation is a long-standing and well-known way to keep the heat in the fireplace for a long time, enjoying the mild equally heat for a long time. Now the furnace accumulation is experiencing its second birth. Deaf inconvenient doors are a thing of the past, as is the technology of their building. The modern continuation of the kiln tradition is the accumulative furnaces and fireplaces, which combine the aesthetics of the fire and the furnace accumulation system.

What for do we need accumulation?

Requirements for wood heating dictate high efficiency and comfort due to the rising cost of energy. Sometimes there is no need for heat from active combustion, but the slow-burning mode does not give the desired effect. Accumulation is very helpful in such situation, because it is capable of delivering heat over a long period.

What is accumulation for?

The tradition of soft heat

With the rising cost of energy, the demands for wood heating dictate high efficiency and comfort. The fire in the fireplace does not burn evenly: at first a small amount of heat is released, then it rapidly increases and the heat becomes excess, and after active combustion the furnace and fireplace are rapidly cooled and the heat does not run out again. Sometimes there is no need for heat from active combustion, but the slow burning mode does not give the desired effect. An accumulation system capable of providing heat over a long period comes to the help.

Calculation of the furnace power

The power of the firebox should be calculated in accordance with the installed system (with or without heat removal ducts) and the heat losses of the premises planned to be heated by the fireplace. Thus, a room with a fireplace will receive the most heat from the fireplace lining and glass.

The power fraction of the furnace emitted through the glass is about 30%.

That is, the room heat loss, where the fireplace is located, should be such that heating the fireplace does not create discomfort. For example, if the area of a room is about 35-40 square meters, you can think of the heat loss of about 1-3 kW (this value is statistical and requires separate study in case of installation). From the fraction of furnace power we can see the following: 3kW / 30% = 10kW rated power. The power of the furnace should not be selected so that its nominal power exceeds that value substantially; at the same time, very low power will not provide enough heat.

The nature of wood-burning implies nonlinearity of heat output, so characterizing its power, we enter the range of operating capacities. It is possible to calculate the amount of heat that will be released during combustion from the number of laid firewood: 1kg of firewood will leave 3.5kW * h of heat. Burning 4kg in 2 hours you can get: 4kg * 3.5kW * h = 14kW * h, 14kW * h / 2h = 7kW.
