Just reading another thread and seen this "we never have the heating on at night" and I've never really understood what it means, but now with energy prices I need to know if its really what people do.
Our thermostat is set at 15 always, in the evenings we up it to 20 for a few hours. I consider 15 off, and 20 on. Is this the same? Or do people just not have the heating on at all, like your house could be 0 degrees? How cold does it get at night? Surely it gets down to single figures most of the time?
