NorthWestern Energy’s Heat Pump Water Heater Program helps customers upgrade to energy-efficient water heaters by offering incentives to make installation more affordable.
What Are the Advantages of a Heat Pump Water Heater?
- A HPWH is a modern, highly efficient electric appliance that delivers reliable hot water while using significantly less energy than conventional models, often making them a strong choice for both performance and efficiency.
- Rather than generating heat with electric elements, a HPWH extracts heat from the surrounding air and transfers it to the water, like a refrigerator in reverse!
How Do Heat Pump Water Heaters Improve Efficiency and Save Money?
- HPWHs can be two to three times more energy-efficient than traditional water heaters, according to the Department of Energy.
- This improved efficiency translates to lower utility bills. According to ENERGY STAR®, HPWHs can save you up to $550 annually, depending on household size.
- HPWHs come with a 10-year warranty and are built for longevity, offering peace of mind with your investment.
- Smart features like Vacation Mode help you save even more while you’re away!
Is a Heat Pump Water Heater Right for Your Home?
- If your current water heater is between 8 to 12 years old, it might be time to consider an upgrade. Switching to a HPWH is a smart choice!
- HPWHs require a little more space to operate efficiently. Your contractor can help you assess the best location, ensure all requirements are met, and if a HPWH is appropriate for your home.
- HPWHs operate at noise levels comparable to those of a refrigerator. Installing outside of bedrooms or “quiet areas” of the home maintains maximum comfort.
- Because HPWHs extract heat from the surrounding air, they can cool the area around them. This makes them perfect for insulated or conditioned garages, basements, utility rooms, laundry rooms or low-use areas.
