We've just moved into a new house (well, really old house actually) and we're renevating our living room. We've discovered it still has the original stone flag floor so we're taking this up, digging the floor out to lay a damp proof course and then laying the floor back down. Whilst doing this we're considering installing a underfloor heating system. We would require a single room system, the room itself is roughly 12 ft by 14 ft. Our hot water and central heating system runs off a combi boiler and I have a few questions related to this fact.
I've read somewhere that you should not turn the underfloor heating system off totally like with a conventional radiator system, but rather have it so it drops to a lower temperature. How does this work from a combi boiler? I've been told the water for the UFH will come from the same system as the radiators - does this mean that I will also have to have the radiators on permantly albeit on a low temperature? Could somebody explain to me how the set up works and is a combi boiler suitable to support a UFH system? (This will have to be fairly simplistic explaination - I'm definately not a plumber!)
