Anybody know about geothermal heat pumps? I looked at a house with
three of these things and I really dont know much about them.

I have one.

You need to find out if they are the "Air Transfer" heat pumps or if
they are actually geothermal heat pumps. That must be a hell of a big
house for three of them. I would want to see the electricity usage for
the last couple of winters before I would buy such a place.

Mine is an Air Transfer heat pump and it does not do a good job
heating the house when the temps get down in 20's. It uses a hell of a
lot of electricity too.

For cooling the house in the summer it uses less electricity than when
I used two window air conditioners.

Before next winter, I will be looking at trying to get a better
primary heat source for my house. I will see if the Oil furnace that
is still in the basement can still be hooked up to the existing heat
pump unit. I might be able to use the oil furnace as a back-up for the
heat pump and have it kick on when the temps get down to 30 degrees or
so.
