Not sure if it is the same thing, but our ground source heat pump
(geo-thermal) home heating and cooling system also produces hot water.
Ours is a Hydro-Delta brand, and is one of the best at producing hot
water (does not use a de-superheater. However, it was a very
expensive system. It will save us money in the long run but only
partly because of efficiency improvement. We also get a special rate
on the electricity ofr it (on a separate meter). Even with that, and
the reduced heating and cooling costs, it will take seven years for
the system to "pay for" itself.
