ᐅ A single- or double-flue chimney

...probably not. If you want to be absolutely sure, ask the chimney sweep based on the documents and the description of the heating system. Unfortunately, chimney sweeps still have the final say here.

Hello,
if you plan to connect a tiled stove or a solid fuel fireplace to a chimney pipe, make sure to also check the ventilation requirements. I made this mistake myself. Some chimneys have a ventilation duct in the middle where you can connect, for example, a fireplace. The advantage is that the stove or fireplace does not draw air from the room, so you don’t have to ventilate constantly in winter and let cold air in from outside.

Only heating appliances with the same operating principle may be connected to one flue. For example, we have a chimney with two flues; two wood stoves can be connected to one flue, but the pellet boiler must be connected to a separate flue because it has a fan. Heating appliances with and without a fan must not be connected to the same flue.
