Back to back gas fires

Oct 24, 2004 3 Replies

I have a bungalow with chimney at one end, and a fitted gas fire in that room.



I will shortly have a single room extension build on this end of the bungalow.



Is it OK to open up the same fireplace from the new room and fit another gas fire.



The result would be 2 gas fires back to back and both feeding into a single chimney.



Thanks Chris


I very much doubt whether you can do this. The installation instructions for my gas fire say quite explicitly that it must have a dedicated chimney. I expect yours is the same.

Absolutely not!

With one fire on and the other off and the appropriate airflow around the house you'd get products of combustion from the working fire coming out of the non-working one. This would be classified as Immediately Dangerous in CORGI-speak and get the appliances cut off, and probably a RIDDOR report to the HSE.

Thanks John Helped avoid a tricky situation. I will put an electric fire in the new extension and leave the current chimney untouched. Cheers Chris
