I have geothermal heat for my house. I have two individual units so that
depending on demand the smaller one would come on when primary doesn't have
the out to keep up with the heat load. The backup strips are generally for
when the heat pumps do not have the capacity to match the BTU lose and the
strips come on general commanded by a three stag thermostat. Heat pumps are
with water heat exchangers would be preferred over the the outdoor units
that pull the heat from the air. These generally stop working and rely on
heater strips when temperature difference becomes to great. My loop line is
at the bottom of a small pond in front of our house. Incoming water temp to
our unit gets down to just below 40 deg F toward the end of the winter. So
far this winter my heater strips have never come on.

I was under the impression that geothermal was intended for places where it
was cold in winter where an air source heat pump was fine in places where it
didn't get too cold. I'm also disappointed to find out that the supplemental
heat has to come on at 10F with geothermal. I was under the impression that
300' down the temp was pretty steady. Is it because OK is so dry that there
is trouble shedding cold down there?

You have the perfect climate for a geothermal heat pump. Not too cold in
winter.

As I said in the original thread:
Ours is a closed loop system from Climate Masters (located in OK). There
are two bore holes, each is 300'. The install took two days for the loop,
and three days for the unit, but you have to factor in that we moved the
location of the unit to another room, installed the new hot water heater
where the old furnace was, and had to install all new ductwork in the
attic. I'm hoping that we'll get 20-30 years out of this system. We are
expecting at this time anyway, to spend the rest of our lives here, so the
up front investment made sense to us. I think that the only time we've had
the auxiliary heat strips (electric) come on was when we were below 10F.
Yes, we'd do it again - my wife loves it!
