We have been setting the temperature back at night for two winters now. I can't say what the saving is, gets complicated because they keep messing with the rates and I haven't tried working out the cubic metre usage. My house though is well insulated double wall with R12 on the inside walls and R20 on the outside walls with a vapor barrier sealed between. even at minus 40 the house looses only about 3 degrees by morning and we sleep with the bedroom window partially open but the bedroom door closed. I think that using resistive heating to supplement pump heating to raise the temperature in the morning would reduce the economy but not by all that much unless it runs for a very long time.
We set back from 22C in the day to 16C at night, I very much doubt the furnace comes on but even if it did cycle a couple of times in that 8 hours or so it isn't much. It does work a little in the morning to bring the air up and of course the ambient mass must also warm up. With luck though we get a little sunshine around quarter to nine to help with that.

Bring the temp back up, and half your savings are gone. If you figure on only getting 5 per cent savings, it hardly seems worth while. During an extra hot summer month my cooling cost might be 60 bucks for a long month. During a very cold winter month my heating cost can go 250 to 400 bucks. Heating cost is always much more than cooling cost. If the average temp for a month is above 25 degrees my heating bill will be less than 100 bucks. ........................bob [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
