nah, I'm waiting for the a/c to go out for that. this is a dedicated water heater that sits on top of the existing water heater tank. looks almost like a pancake compressor.

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.
