I am installing an oil fired central heating and hot water system. I plan to use 22mm copper pipe as the main primary feed and return, with 15mm pipe as the radiator supply and return. Should I run the 22mm pipe as close as possible to all radiators? Am I best avoiding long runs in 15mm pipe? Can anyone direct me to good in depth guides on central heating installation and plumbing? Anything I have found so far is either very basic or generalised.So any info on the installation for a semi detached house with 11 radiators and 1 hot water tank would be greatly appreciated.
