What was the recovery time after the setback days?

Hi Doug,

I don't know with certainty, but I do know it to be less
than an hour.

All the best,

Please be careful on high wind load, very cold days - I would suggest
that if you know that the next day is going to be that way you not do
the setback.

I have had Geothermal for more than 20 years, in the early winter and in
the spring, set back saves a lot of money, but from about the middle of
December to the End of February here in Michigan, we do not do a
setback, since the secondary electric elements cost way more than the
savings.

I am looking at adding solar thermal heating the south wall of the house
next summer to further reduce the winter heating bill. I have 60 feet of
southern facing wall that is in direct sunlight almost all of the day.
That should give me a good thermal boost on even partly cloudy days.

Doug

Hi Doug,

Your offer good thoughts for the general geo situation, but
we do not have resistance auxiliary heat in either of our
two buildings. Our systems were designed for 20 year cold
days.

All the best,
