Turn thermostat down or leave steady?

Posted by Stormin Mormon on October 29, 2009, 8:22 am

Please forgive me while I troll for a moment.....

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.

To elaborate, heat loss slows as the house cools (delta T is lower) so
it takes less energy to maintain the house at a lower temperature and
then heat it back up again. Especially so if the house is not well
insulated.

That said, I have not noticed any drop at all in my gas bills since
installing a programmable thermostat :(

No, it takes too long to re-heat the boiler and all the water in the
pipes, radiators, and floor tubing. It is always best to set it once
and leave it there all winter. Too much energy is lost when all that
water is asked to re-heat all the surfaces again. For example when I
feel the return manifold from the coils under my concrete slab after
the slab was allowed to cool, the return water is ice cold, all that
energy to reheat the slab. No, bad asvice, best to keep it warm and
leave it there, saves tons of energy.

I hope that you were just kidding because obviously you are wrong! Just
think for a minute.....if you were going to be gone for three months
don't you think you would save energy if you turned your thermostat
down? Well, the same would be true for a few hours, just not to the same
extent.
