Storage stove
A storage stove (also known as a “ basic stove ”) is a closed fireplace made of ceramic or natural stone . The heat released when the wood burns is absorbed by a (mostly ceramic) heavy storage core. After the wood burns, this core releases the stored energy evenly over the surface of the storage stove in the form of thermal radiation for a long time .
A storage stove consists of a combustion chamber , a burnout zone and a ceramic heat exchanger , the storage core. The exhaust gases and soot particles of the fuel , for example from finely chopped firewood , are burned during a burning process at high temperatures (800–1000 ° C) and thus release a high level of energy.
In Germany, a stove that meets the DIN EN 15250 storage heater standard can call itself a "storage heater". Most stoves are wood-burning stoves with integrated storage and only tested in accordance with EN 13240 (wood-burning stove standard). This is a standard for long-burning stoves that have to be heated and continuously refilled. A long-life stove is by definition not a storage stove.
Some manufacturers produce ovens with closable air slots (e.g. Austroflamm, Drooff, Cera). If you want a quick heat release, open these slots ; if you want to store a lot of heat in the oven at first , lock it.
Storage stoves are inherently heavy.
