I'm running two new rads and my system is 10mm microbore (thought it was 8mm upstairs but they all look the same size to me now.)
I don't know if I have a manifold. There's a rad in the house that I think wasn't there when it was built so I lifted the floorboards on the upstairs landing expecting to see evidence of a board being lifted but there wasn't.
I'm assuming that if I lift a floorboard up near a rad, if I have a manifold I'll see nothing but 10mm but if I don't have a manifold I'll see the 22mm flow/return with the 10mm teed off? If so how far away is the rad likely to be from the 22mm flow/return?
If it's on a manifold where am I likely to find it? There's a spot on the floor in the bathroom that gets warm but it would seem strange not to have it located centrally.
Whichever system it is, I assume I'm best sticking with 10mm for the new rads to avoid starving the existing system of heat?
Also, if it turns out not to have a manifold, as the new rads are a few metres away from the nearest existing rad due to being in what was the garage, would I be best off extending the flow and return before teeing of in 10mm?
Cheers,
Dan
