ᐅ Simply connect the stove to the chimney? Drilling the flue outlet

Hello,
I have just bought a wood stove and now want to connect it to the chimney. I live in a terraced house with a gas heating system, and everything goes through a shared chimney flue. Do I need to consider anything specific, or can I simply drill the flue outlet?

Hello,
you should definitely ask the chimney builder and the chimney sweep first. As far as I know, it is not possible to connect a different stove to a chimney that was originally designed for gas. This has to do with the chimney’s cross-sectional area. In addition, the pipe is only intended for gas exhaust gases!!

Hi,
that’s correct, you can’t simply connect a wood-burning stove to a chimney that was designed for a gas heating system. A chimney for burning wood needs to have a larger cross-section, whereas a gas chimney is smaller. If the chimney is too small, it can cause exhaust gases to be pushed back into the house, which can be deadly!!!!

It is not allowed at all to connect a wood stove to a chimney that is already used for another purpose (regardless of whether it is gas or oil).

If you do not have an additional chimney or do not want to install one, then the stove will not work. In this case, consider returning or selling it. However, the question arises as to why you did not clarify this before purchasing. That would be the obvious step before spending money on it, wouldn’t it?

Furthermore, it depends on the stove’s heating capacity in kilowatts (kW) and the effective draft height up to the roof exit. Only then can the optimal flue cross-section be specified or determined.

Bauline is absolutely right in what he says. You cannot just connect any stove to a chimney. You can only try to return it and hope to get all your money back. In cases like this, you should always consult the chimney sweep beforehand.
