No surveys or studies needed to address this question. The Second Law of
Thermodynamics decrees that the speed and extent of all heat transfers in
the universe depends solely on the temperature differential between two
objects. The moment you turn down the thermostat you start saving money.. The
longer you keep it down, the more money you save.

Is it energy saving to turn the thermostat down, when
leaving the house? I mean, the furnace has to run to catch
up when I get home. I have a way of looking at the matter.
I'll explain my point of view after the argument is
underway.

Yes, you save energy turning it down. *In balance less heat is lost.

What happens when he comes home and turns it back up again? *The
reverse, so where is the savings?

RickH-

Looks like there is very little hope for you understanding the thermo
of setback....

Walter made a very simple / concise statement of the value of setback
but you still choose to disbelieve it.

The energy saved is the amount of energy used to maintain the house
at the setback subtracted from the energy that would had been expended
to maintain the house at the higher temp.

outside temp 50F inside temp 70F (without setback)

outside temp 50F inside temp 60F (with setback)

house at setback temp loses ~1/2 the heat that the house at "normal"
temp
