An airtight wood stove alone only gives off heat while the fire is going. When the fire is out, the heat is gone. A heating wall however stays warm long after the fire is out and gives up radiant heat. This is a heating system independent of electricity and fossil fuel.

All that heat from the smoke that would normally just go out the chimney, travels through the wall and is absorbed and stored by the masonry construction of a heating wall and then comfortably and gradually released back to the surrounding areas. With a heating wall the smoke which goes out the chimney has approximately 80 120 degrees Celsius, with an airtight wood stove up to 300 and with an open fireplace even up to 500 degrees Celsius. There’s a huge amount of energy saving with the wall and little of no pollution to the environment.

The wall could be build against a non-combustible wall or used as a dividing wall between two rooms with a length up to eleven feet. Almost any type of wood stove could be connected to a heating wall.

With an airtight wood stove a lot of people restrict the airflow so that the burning holds on longer. But wood has to burn at its full potential to maximize heat gain, to reduce ash and harmful emissions and to burn off creosote. Quicker burning heats up the wall faster. A big energy push produced by the stove connected to a heating wall will be caught in the big storage wall to be let out slowly to the room as radiant warmth. Therefore you even can use softwood which burns faster. This saves you money, because soft wood is much cheaper then hard wood, often even for free. And as with any wood burning device, you only should burn dry wood. The dryer the wood, the more heating value and the less creosote!
