A wired Thermostat, how quaint! Only joking, we only switched over to wireless earlier this year when we had a new boiler fitted.

My recently installed gas central heating has a portable thermostat with a radio link to the boiler. It does however read 2 degrees higher than any of the thermometers I have in the house. I wonder if it has been "adjusted " by the eco-police.

Well yes to some extent. Modern stats are intelligent (not ). They use a type of fuzzy logic. Old stats had a neccessarily wide hysteresis loop which meant if the stat was across the room from the heat source it took a while to react to the rise in temperature and even when the stat turned off thevtemperature would still climb as the heat source still outputting at that point. New stats predict this effect so will turn the heat of and on a few times before desired temp is reached. this wil vary with the amount of temperature difference demanded by the user. the end goal being not to overshoot required temperature.
