I think you're onto something here. This does sound like a plausible
explanation. Keeping your house at a constant 18 degrees could well be
cheaper than oscillating between off and 24 degrees, and this is what a lot
of people end up doing. Of course if you get the timing right and have it
warm up to 18 in plenty of time so that you don't get the "I'm
freezing, turn it up" effect, then that would be cheapest of all.
Sounds like a good argument for a sophisticated radiator control setup! Can
anyone recommend some good budget centrally controlled TRVs?
