Heat Pump Water Heating
Heat Pump Water Heating

Heat pumps are a very efficient way to heat water - they're available at big box stores today for home use. They're a great way to "cut the pipe" at home. At a larger scale, they can do the same in hospitals.

Newer equipment uses carbon dioxide as the refrigerant. "Conventional" heat pumps use R134a, which has a Global Warming Potential of 1432, compared to CO2 GWP of 1. CO2 heat pumps can provide hot water up to 190F, allowing use in existing buildings designed for higher heating water temperatures and storage-type domestic water heaters.
