Hello,
Just a question regarding converting from a back boiler to a combi boiler.
The back boiler has gravity circs and a pumped central heating circuit. The gravities are in 28mm, and remain in the airing cupboard now the cylinder has been taken out. Is the any reason why I couldn't join the 22mm heating circuit to the 28mm gravity circuit in the cavity of the fireplace where the back boiler was? Would this then make the old 28mm gravities in the airing cupboard the new flow and return for the combi. I'd just need to reduce them to 22mm, and pipe straight into the combi.
I've given this some thought, and can't see a reason why it wouldn't work. Apart from the old pump, but this would no longer be wired in anyway.
Thanks for any advice.........or abuse
