Definitions
- the invention relates to a heating furnace according to the preamble of claim 1.
- Wood-burning stoves are very popular because the type of heat given off is perceived as very pleasant.
- the air is not heated, but the walls and all solid bodies in the room are warmed in particular by radiant heat. Circulation of the air is also largely avoided, so that there is no further contamination of the air with dust.
- the air humidity and the balance between positive and negative ions are maintained, so that a healthy, natural indoor climate is created.
- a disadvantage of wood-burning stoves is that the quantities of wood required for their operation require a considerable amount of space for storage. This space is often not available, especially for row houses on small plots and for multi-family houses.
- Combustion chamber with heat-storing material is to ensure that the heat generated during the combustion process is stored and radiated continuously.
- the combustion of heating gas such as natural gas, town gas, liquid gas (propane, butane gas, etc.) or heating oil, generates considerable amounts of water vapor. Since the heat-storing material in this known furnace is in direct contact with the combustion chamber, the heat given off during the combustion is immediately dissipated to the heat-storing material. The combustion chamber therefore only reaches its final temperature very slowly, and this remains well below 100 ° C. A temperature of 100 ° C or possibly even higher would also have to be avoided due to the risk of the operator being burned by the heat-storing material.
