Hi,
I was hoping someone qualified could please assist me?
I've recently had a large extension added to my house and I'm concerned the pipe work for the central heating is not appropriate.
My existing central heating system has a 22mm trunk for flow and return. Off the trunk, each radiator is branched using 15mm (one rad per branch). My concern is that the central heating guys who have put the pipes in for the extension have not followed the notion of one radiator per branch. They have put in 4 rads (totalling 18500btu) on a single 15mm branch off the trunk. This has effectively reduced the trunk to 15mm for those 4 rads They have respected the flow and return.
I had anticipated they would have followed the layout that had already been establish. I'm concerned that such a large load on the 15mm branch will mean the heating won't be effective.
FYI,I now have 14 rads in the house.
I questioned they guys who put it in, but they effectively told me to go away as there was nothing wrong with it.
Could anyone please advise on if I am right to insist on maintaining the one rad per branch model? Thanks in advance.
