During the winter when our central heating is on, the temperature of our house seems to vary widely. I have confirmed this by temporarily putting a digital thermometer next to the room thermostat on the wall which controls our heating. The room stat is set to 20C - the digital thermometer shows the temperature going as low as 18.1C before the thermostat activates the heating - it then goes as high as 22 before it switches off again. In other words, its "range" seems to be very wide. 4C is a lot - 18C feels pretty cold, and 22C is uncomfortably warm. As such, we're constantly altering the thermostat to make the heating come on/off, which only makes the problem worse.
I've looked at newer, digital thermostats (e.g. Drayton), but even some of these seem to have "ranges" of over a degree.
My digital thermostat is accurate to 1/10th of a degree C, and I wish it was possible to control the activation of the heating system with such accuracy. Anyone got any ideas?
I realise there would still be some "bounce" effect (for want of a better term!) - i.e. when the house reaches 20.0C, and the heating is switched off, the rads are still going to be hot, and the temperate will continue to rise a bit. I can live with that - but having a thermostat where the difference between "on" and "off" temps is nearly 4C seems crazy.
