Our room thermostat is placed in the hall of our bungalow - about 6 inches from the opening door to the airing/hot cylinder cupboard. The wall it is on backs onto the broom cupboard in the kitchen(which is next to the airing cupboard side wall. With me so far !! I have noticed that most people have the thermostat set to 16/17 but we have to have ours on 24 before the boiler will kick in. Is the stat thinking the hall/house is already warm cos of its position on a warm wall? does this self calibration cause any probs/issues. Thank you !
