Domestic hot water (DHW) accounts for roughly 25% of annual energy usage in typical multifamily buildings[1] and is the largest single energy use of energy for new multifamily construction in the Northwest.[2] The Heat2O heat pump water heater (QAHV-N136TAU-HPB(-BS)) reduces the environmental impact of DHW through energy-efficient operation while using CO2, a natural and environmentally friendly refrigerant with a global warming potential (GWP) of one and an ozone depletion potential (ODP) of zero. Able to produce high volume DHW without fossil fuels, Heat2O can help multifamily buildings, offices, hotels, gyms, educational institutions and other large-scale and commercial facilities qualify for sustainability certifications or achieve zero-energy and passive house status.
