Whats peoples views on what pipe size i should use in the following scenario:
2 x 3 bed houses being converted into a 4 bed.
13Kw heating demand fed via a Worcester 42Cdi Combi, 550Cdi high flow or 35i System boiler - Customer undecided yet although i have recommended due to hot water demand required to go with the system boiler and cylinder.
22mm from boiler and main skeleton or 28 mm and reduce to 22mm after some of the heat load has been took off to some of the rads ?
I was thinking 22m should be fine but upon checking through various sources i keep reading conflicting advice which is making me think possibly some 28 may be needed ?
