Hot Water, Cool Planet: Heat Pump Water Heater Developments that Minimize Carbon Emissions

This video is provided by the Building Efficiency for a Sustainable Tomorrow (BEST) Center and features a presentation from Peter Grant, a technology researcher in the Energy Technologies Area at Berkeley Lab. During the video, Grant discusses heat pump water heaters, decarbonization, and new advances. The role and importance of heat pump water heaters in decarbonization is explained and emission reduction from the switch from gas is highlighted. Grant also covers grid challenges including the duck curve and the evening peak problem. The presentation concludes with key takeaways like heat pump water heaters perform well, will reduce CO2 emissions, and offer lower operating costs with retrofit-ready models, load shifting controls, and low-GWP refrigerants.
