Heat Pump Water Heaters
Most HPWHs are fully indoors, with all pump elements housed in the same unit as the storage tank. Many HPWHs are “hybrid,” meaning that they also include electric resistance heating elements to provide backup heating when hot water demand is high.
- As they run, HPWHs dehumidify and cool the air around them. While this means you may need a little more space heating in the winter, it can help manage mold and cooling concerns in the warmer summers.
- HPWHs are a bit noisier than a typical water heater, at around the same volume as a window air conditioner. Many folks keep their HPWHs in the basement and barely notice a difference, but reach out to an EnergySmart advisor to talk options if you are particularly sensitive to noise or vibrations.
- HPWHs cost a bit more up front than their counterparts. However, their energy savings typically offset the cost difference–plus, there are some great EnergySmart rebates that can help manage the up front balance as well.
