The California Public Utilities Commission voted unanimously to support energy efficient heat pump water heaters.
According to the NRDC, the $45 million allocation is part of the $830 million over five years approved under California’s Self Generation Incentive Program. The program is intended to help develop on-site power generation and energy storage systems.
“Heat pump water heaters are up to five times more efficient in heating water than conventional water heaters,” according to the NRDC. “Heat pump water heaters work like a refrigerator, only backward. Instead of pushing heat out, they use electricity to collect, concentrate, and move heat from the air around them into the water in the tank—where it can be stored hot for use hours later.”
The CPUC left itself open to allocating more money to heat pump water heaters later.
“This is a very efficient emerging technology that can greatly assist in reducing greenhouse gases,” CPUC Commissioner Clifford Rechtschaffen said. “It can also help in managing peak load. Water can be heated and the right times and then used later. We are going to need hundreds of millions, if not billions to deal with this issue, it’s important to start transforming the market as soon as possible.”
