Heating system

Posted by philip jefferson, on
I was looking at plumbing my new heating system myself and was wondering about pipe sizes. I was thinking of running 28mm pipe and then taking T's of to radiators in 15mm for both flow and return and was wondering if it would be suitable size pipe

You can run up to 45700 btu from 22mm pipe and 13600 btu pipe so you can calculate btu output from radiators an run correct pipe sizes from that calculation
