I am having problems deciding on which type of under floor heating to install in my new house, Can any body tell me roughly how much does it cost to run an electric under floor heating system? There are two main types, Electric boiler & electric mat, Every body I have spoken to has a different opinion, some says it’s the best thing since sliced bread and the next says don’t go near it. Any help would be much appreciated (***Mod Edit - Moved to Consumer Advice & Resources***)
