Im currently in the middle of trying to decide on a heating system for our new house in New Hampshire (just north of concord). I have been looking at heat pumps and currently have a water to water unit providing 54K Btu heating plus a water to air unit providing 42k Btu of heating and 50.5k Btu of cooling. This gives me 96 Btu of heat to cover 83K Btu/hr of heat loss. This will be running off of 10 ground loops burried about 7 feet underground. The water to water unit will be used to run the radiant heating system throughout the house. The water to air unit will be used as a primary backup and quick recovery time during the winter. We can have 40 degree temperature swings during the winter. Obviously, AC in the summer. The air unit also has a 15KW electric heat backup as a third source.
I guess I need to check my untility rates, as Im not sure of them as I sit here. My utility company does offer rebates on the hardware as well as discounted rates to run the units.
With NH haveing very high utility rates, am I being foolish in looking into these systems?

This is my personal opinion. I like to keep things simple, the more you have the more there is to break. Gas heat, either natural or propane, are good systems and service personnel are familiar with them. It comes down to what kind of system you prefer, kind of like what kind of car you want to drive. Ground source heat pumps do work and are efficient. Sleep on it before chosing.
