I've got a Horstmann wireless room thermostat - is it possible that the sensor for room temperature or whatever it is, can go on the blink?
If I have it set at say 20 or 21 degrees, it's showing as heating on, but the radiators are only a bit warm so the house is freezing. If I turn it up to 22 or above, I'm nearly dying of heat exhaustion and the radiators are absolutely roasting.
