I'm after some advice on moving a radiator some distance from its current position and replacing it with one of those tall/narrow designer rads - probably something like this:
Rad I want to move is the last rad in the system in my dining room furthest from the boiler and fed down on 10mm microbore reduced from the 15mm pipes running across the back of the house in the ground floor ceiling (concrete floored house).
I'm having an extension built and the rad is under the dining room window which is being knocked through.
Just before this rad is the one in the bedroom directly above -teed off on shoft sections of 8mm microbore.
What I'm thinking of doing is chopping and end stopping the pipes after the bedroom radiator (making that the last in the system). I'm then going to tee a couple of pipes off just before the bedroom rad and run them across to the other side of the dining room ceiling and down the wall - a distance of approx 8ft horizontal and 7ft downwards. This will need to be done on either
10 or 8mm microbore as its a awkward pipe run.My question is whether there is a risk of poor water circulation AND whether the pipe size is critical - i.e. use 10 rather than 8.
TIA, Midge
