Heat pump water heater rebates are available on an annual basis to CMLP's residential and commercial customers.
Heat Pump Water Heaters (HPWHs) - also called Hybrid Water Heaters - are powered by electricity, b
ut are much more efficient than previous electric water heaters, which exclusively used electric resistance to raise the temperature of the water. HPWHs can use electric resistance when needed (such as when a homeowner has visitors staying with them, causing an increased load on their water heater), but their default is to use heat pump technology.
