I had a potton 100 Central Heating boiler feeding 4 large (double) radiators downstairs and 6 large (double) radiators (plus 2 small bathroom rads) upstairs. The flow and return were 28mm splitting into 2x22mm one for upstairs and one for downstairs. My builder is building an extra downstairs room necessitating changes to pipe runs. His plumber has changed the pipework to:
1. Short length of 28mm from boiler reducing to 22mm connecting to upstairs 22mm rad feed circuit.
2. Then a 15mm tee off this 22mm circuit to connect across to the downstairs 22mm circuit.
Any pros out there have any opinions on how performance will be affected by this?
Thanks
