High Performance Decarbonization Technologies

High Performance Heat Pump Water Heaters

What’s Included: 

The products included in this list are all high-efficiency heat pump water heater systems that utilize a natural or ultra-low GWP refrigerant, for both commercial and multifamily building applications. Multifamily systems include both 120V and 240V, and distributed and centralized systems. 

How to Navigate: 

Use the tabs at the top of the table to toggle between commercial and multifamily products. Use the filters on the right side of the table to search by system configurations, performance characteristics, refrigerant type, and more. To view all the system specs, scroll all the way to the right in the table to access the spec sheet from the manufacturer or click the blue square to see all the product information in one place. If you’re on the mobile version of this site, please switch to desktop version for a more accessible dashboard.
