The Chiltrix Air To Water Heat Pumps Have The Highest Efficiency Ratings For Heating & Cooling Among All Officially Certified Air To Water Heat Pumps.

CX65X EVI MAX Air To Water Heat Pump



Above is the CX65X. The same basic machine as CX65, the X model has a stainless steel pump and an aluminum front grill. See side/rear pic CX65X. The CX65 has a cast-iron variable speed pump and non-metal fan grills..

The CX65 & CX65X use the same award-winning USA patented technology as CX34, CX35, and CX50.

It's a Trifecta! The CX65 has been optimized for record-setting cold-climate heating performance while still beating every other brand of air to water heat pump in the industry for cooling efficiency. And Chiltrix holds the #1 highest rating for domestic water heating with UEF 4.95.

Both CX65 and CX65X include DYNAMIC HUMIDITY CONTROL (DHC) factory Installed on all units. *Requires indoor RH sensor.
