Product Description
The Chiltrix CX50 cold climate ATWHP has Europe's Highest Efficiency Rating! Why does this matter here in the USA? Why does SCOP matter in the USA?
CX50 uses the same Energy Star award-winning controls technology as CX34 and CX35. And, it has been optimized for much higher heating performance while still beating every air-to-water heat pump in the industry (except other Chiltrix models) for cooling efficiency.
