Re: [GBlist] re: Heat Sources

Yep our system provides radiant heat for the lower level floor (exposed on
the south side), hot air (via an air handler) for the main level, and 2/3 of
our domestic hot water requirements. In the summer we run the system
backward and get cooling in the upper level. Installed system cost-
including the ground loop- was $12K. Average monthly operating costs during
heating and cooling season is <$30.
I would not recommend radiant cooling in a concrete floor however. Not
comfortable, and conducive to condensation.

Cheers,

Chris
