What should I look for when buying a stove?

The last German winter was again particularly long and cold. The prices for gas and fuel oil are not cheaper. No wonder that more and more homeowners are looking for ways to reduce the heating bill. The conversion to heating with renewable energies is a sensible investment, which unfortunately can not easily be solved by every family. For them, a wood-burning stove in the living room is a better, more leisurely choice for getting warm during the cold months of the year. Whoever imagines a stove will primarily think of the romantic atmosphere he conjures up in the living room. While still open fires are still shown in films, the modern model is no longer open: this would not only burden the air and health, but also the environment. A firebox door is therefore mandatory for every stove. Thanks to good glazing, the cozy atmosphere is by no means lost.

In addition to these practical conditions, there are also some communal and country-specific regulations that must be observed in order to operate a stove.

The inner diameter of the chimney must be the same as that of the flue pipes.

The minimum chimney cross section must be the inner cross section of the flue pipe socket

  • Keep a safe distance between the stove and surrounding objects (20 cm to metal parts of the stove, 80 cm to the firebox).
  • If the stove is not on tiles, a stone oven or other refractory surface,
  • Observe the theoretical heating capacity of the stove
  • According to DIN 18893, the room height is given in three different heights:

favorable heating conditions (GH)

less favorable heating conditions (WGH)

In this case, the installation space is deprived of air and it can create a dangerous negative pressure. Affected persons should additionally install an external combustion air supply. This will add air from the open air to the stove. However, a stove must support this function, pay attention to this marking when buying in online shops. Get advice from the chimney sweep

Buying a stove is not just a matter of taste. The stove must fit in with your own home, and nobody can advise better in this area than the local chimney sweep. Who wants to install the stove retrospectively, but does not have a chimney, do not despair. In this case, a double-walled stainless steel pipe is mounted on the outside wall of the house. The exhaust pipe is then connected to the external chimney. Before such procedures are carried out, homeowners should seek advice from their chimney sweep. He will eventually dismantle the installation and help avoid problems from the start. It informs interested parties about fire protection aspects and safety distances to combustible materials.

Observe new immission regulations

If homeowners decide in favor of an oven, they must make sure that it complies with the currently valid immission regulations. Around five to six million households nationwide have the problem that they have to go out of service in the coming years because they do not meet the Federal Immission Control Ordinance of 22.3.2010. Although this regulation has been in force for three years, it remains largely unknown or simply ignored. It applies to all newly purchased or installed stoves, including old, used stoves. Oven owners must report to their chimney sweep by the end of the year which standard complies with their stove. If you refuse, you must shut down your stove.
