Why heat pumps?

Heat pumps are ideal for California's dry, temperate climate and can be used for space heating, air conditioning, and water heating. Heat pumps also give customers greater control than conventional technologies, which leads to more comfortable homes.

According to the California Air Resources Board, 85 percent of on-site building emissions come from space and water heating and cooling. Heat pumps are key to decarbonizing buildings and achieving California's zero-carbon goals.

"I think the heat pump water heater performs much better than the previous gas water heater. We have had no complaints about hot water supply and the energy usage is way, way down."
