Are you controlling the heating in each room separately? From your description saying "relay", I'm presuming this is electric heating? Do you find that this keeps all the rooms around the right temperature? The usual problem with a normal heating system is that you have parts of the house that regularly are hotter or colder than the rest, so I was wondering if you had managed to solve this. I'm looking to control radiator valves electronically, which of course relies on someone actually making electronically controlled radiator valves that don't cost a stupid amount of money.
