As for turning down your thermostat, WHY!
Grumpy, didn't you know? It's because highly 'respected' national testing laboratories say that there is a savings to be had! ... but I don't believe them either.

It IS of course true that if you turn down and LEAVE DOWN, or turn down for an extended period of time, of course there will be a savings... but like you, I just can't buy into the fact that turning down for a few hours while we sleep, or are at work, will save anything worth anything. Several years ago I did some experiments that proved this sufficiently for my own use.

As Xiphias pointed out, a HOT AIR system that 'recovers' quickly will be more likely to have a bit more savings from setback strategy.

All that said, I DO set back my t'stat at night... but only 2F for sleeping comfort. If my system were zoned, I would just leave the bedroom set back.
