Hi all
I currently have 6 old radiators (downstairs) off what looks like 15mm pipework. It comes off the zone valve in 22mm and then goes under the suspended floor and is 15mm throughout. It takes forever to heat the rooms and as the radiators need replacing anyway I was looking to upgrade to 22mm pipework and then tee off in 15mm for each radiator.
The question is how many radiators can a 22mm pipe supply, I know as a rule of thumb 15mm shouldn't be anymore than 3. I have the following I need to fit for now on one side of the ground floor and as we refurbish other areas there will be another 5 rads which will come off a tee after the zone valve:
Thanks in advance
