hi all
im renovating a 3 bed semi d i got a few months back. im putting in a all new central heating systems. i got all the rads (7) there size for each room and trv for a good deal a long time back. i need to run all the pipe work now so i can close up some 0f the rooms.
im running really low on cash as i never expected to do so much work to this house.
so my questions are
from were the boiler will be i was thinking of runing two runs of 3/4 pex flow and return
and then use 1/2 pex to do the drops to each rad but iv have just opened the vavles that came with the rads and they are 15mm so is it best to use 15mm for the drops to main 3/4
any help on pipe sizes would be great .
thanks
