I've been involved with numerous installations... We're even installing the
outdoor units indoors to cover the loss of heating in our cold climes.
The Hyper Heat & water cooled units are fantastic...
When they finally put a Cupronickel heat exchanger in the PUMY series,
Mitsubishi will own the residential Geothermal market.
