Hi,
My bathroom hot & cold water pipes and central heating pipes run through a loft area of my house. Last year the central heating pipes froze in the cold, so I added radiator anti-freeze and that has been OK since.
This year, the water pipes are frozen.....
The problem is that the pipes have been run along the inside face of a North facing exterior wall inside the loft area, but have not been insulated. The loft area gets cold and the pipes freeze (the previous owner has even retro-fitted radiators in the loft area, so maybe had similar problems to those I now face).
The two water pipes are fitted very close together and tight to the wall; so close that I cannot get polyethylene pipe insulation around the pipes.
What are my options for insulation? I was considering either coating the pipes in expanding foam (do not really want to do this though, as it will make any future maintenance a pain), or spiral wrap (I think with some effort I can wrap around both pipes, although they are fitted very tight to the wall). I read here http://www.essortment.com/home/installingpipe_ttbe.htm that you can get spiral wrap with a very small electrical current passing through it. Has anyone seen this in the UK before, can anyone recommend it, and does anyone know any suppliers?
