hmm.

hate to put a downer on the idea but from a pure saftey point of view i wouldn't. im a plumbing and heating engineer and have heard of and seen some nasty installations. mind you could just be nature of the job

there are other options, have you considerd under floor heating expensive outlay maybe but dependand on type fitted can be a lot cheaper to run than you think.

out of interest have you got central heating?
