Thanks, it is an ideal Combi. These pipes are ground floor direct from the boiler. There is a tee taking the flow and return to upstairs and two other tees taking them to existing downstairs radiators.
Hoping someone can help identify whether these pipes can be used to add a radiator to the existing system. The top pipe is a 22mm Flow with a drain valve on the end and the bottom is a return which has been capped after being reduced to 15mm.
Can a tee be inserted on the flow and the return...
