Learn Why Heat Pump Water Heaters Are So Energy Efficient
July 15, 2021 – 12:00 Noon, 1 hour webinar


A gas water heater can never be more than 100% efficient.  Most are only 70-90% efficient. In contrast, because a heat pump collects heat from the ambient air, a heat pump water heater delivers 3-4 times more heat energy than the electrical energy it uses!  In addition to saving you money, heat pumps offer multiple environmental benefits. A gas water heater contributes to global warming via the CO2 it produces directly and via the methane that leaks from the delivery system. Because California’s electricity is already 50% renewable and getting greener, converting to a heat pump water heater will help you reduce your environmental impact.
