Spring Into Savings with a Heat Pump Water Heater

As Maine settles into the wetter, warmer seasons of spring and summer, it’s a great time to consider upgrading to a heat pump water heater. Heat pump water heaters are not only one of the most efficient ways to heat your water — they also help reduce excess moisture in your home. That makes them especially appealing this time of year, when humidity levels tend to rise and basements can start to feel damp.

Heat pump water heaters work like air conditioners, but rather than moving heat from the room to the outdoors, they move heat from the room into the water tank. This process helps dehumidify the space around the unit, making it particularly well-suited to basements and utility rooms. While a heat pump water heater won’t fully replace a dehumidifier, it can significantly reduce the workload on one.

In addition to keeping your space more comfortable, heat pump water heaters can help you save on energy costs. Compared to traditional electric models, they use over 70% less electricity, potentially saving you more than $500 per year.* Right now, Efficiency Maine incentives make it possible to pay as little as $299** for a heat pump water heater after instant discounts. Plus, they typically come with a 10-year warranty and produce plenty of hot water to meet your household’s needs.

If your current electric water heater is over 10 years old, now is the perfect time to make the switch. With instant discounts available and warm weather making installation more convenient, there’s no need to wait until your old unit fails. Whether you install it yourself or find a participating installer through Efficiency Maine, a heat pump water heater is a smart upgrade that will serve you well for years to come.
