Hi all,
Looking for your best advice...
I have recently built a small single storey extension approximately 4m x 5m. I plan to install two new radiators.
The existing system has a header tank and pump. The flow & return are 22mm. On the ground floor all the rads are fed by 10mm pipe, on the first and second floor the rads are fed by 15mm pipe.
My question being should I tee off the flow & return in 22mm and then reduce to 15mm to the two new rads, or can I just use 15mm all the way? I'm not a fan of microbore, so hoping to avoid 10mm unless there is no alternative. New rads will be about 4m from the existing flow and return.
Thanks for your help.
