This geothermal heat pump delivers the comfort with hot water for your radiant or hydronic system putting you in hot water in a good way.

Carrier's® GT-PW water-to-water model produces hot water only and can be as much as 5 times more efficient than a traditional boiler system. Because of its high-heat capacity, it could also be used as a dedicated hot water source for your home.
