Hi,
I need to run flow and return pipes roughly 10 metres horizontally, to feed three radiators.
I am going to run 22mm from the boiler, up to the ceiling, across a corridor, into the target room and then down to skirting level. I then need to run 10 metres along the wall, teeing off to the rads as I go.
Should I go the whole 10 metres with 22mm and then tee off with 15mm, or can I get away with 15mm for some of the run?
Any advice would be much appreciated.
EDIT: Each of the rads is approx 3kW
