I am a fairly competant d.i.yer looking to install gas central heating in a two bedroom house. To keep costs low I plan to install all the radiators myself and have a plumber install a Baxi 105e instant boiler.
I am unsure about the radiator circuit. Do I run 22mm copper pipe from the boiler then reduce to 15mm to all the radiators then stop the supply / or rig a 22mm circuit offtaking 15mm to the rads then returning to a 22 mm pipe back to the boiler . My problem is do I Make a circuit or feed only to the rads then return from the rads back to the boiler
