I am in North Carolina and a heat pump here looks like an air conditioner.
I was not thinking about the expensive geothermal heat pump when I made my
comments.

What about heat pumps that use ground water which 5 feet deep and down
runs around 50-55F Up here they either put down, 4 to 6 50' wells (give or
take), or plant a large pipe network depending on the heating degree days.

You need to be in a warmer climate for heat pumps to work efficiently. I
have several units and my main floor one also has a propane furnace that
takes over when it is less than 30 degrees outside.  I have noticed no RFI
with any of my American Standard heat pumps.
