How Much Can a Rheem Heat Pump Water Heater Save You?
May 19, 2025
Through a combination of energy efficiency, proper mode selection, and available rebates and incentives, homeowners can save thousands of dollars over the life of their heat pump water heater.


When it comes to energy savings at home, few upgrades deliver like a Rheem® ProTerra® Hybrid Electric Heat Pump Water Heater (HPWH). These innovative systems can dramatically reduce your utility bills while delivering reliable hot water for years to come. But just how much can you save—and how do these systems work to cut costs? Let’s dive in.
Energy Savings That Add Up
Traditional electric water heaters generate heat using electric elements – basically they burn electricity to heat your water. Rheem heat pump models, on the other hand, capture heat from the air and transfer it to the water tank. This process uses far less electricity—up to 75% less, in fact. For a typical household, that translates to up to $372 in annual savings compared to a standard 50-gallon electric model. Over 10 years, you could save as much as $3,720 —and possibly more if energy costs rise. For larger models, savings can be as high as $576 per year!
Smart Operating Modes = Even Smarter Savings
Rheem HPWHs come with multiple operating modes, giving homeowners the ability to customize performance and efficiency based on their needs. Using Energy Saver or Heat Pump Mode during typical usage periods can reduce energy use drastically, especially when paired with time-of-use utility rates or off-peak schedules. That means more savings without sacrificing comfort.
- Energy Saver: A smart blend of heat pump and electric heating. It uses the heat pump for daily efficiency and kicks in electric elements during higher-demand times for faster recovery.
- Heat Pump Mode: The most efficient mode. It relies solely on the heat pump technology for heating water, resulting in maximum energy savings.
- High Demand Mode: Great for busy households, this mode prioritizes speed—using more electric heating to ensure you never run out of hot water.
- Electric Mode: Works like a traditional water heater. This can be used temporarily, for example during very cold weather or unusually high demand for hot water.
- Away/Vacation Mode: For extended periods of no hot water demand (2-28 days). Maintains 65°F water temperature for Highest Energy Savings.
Bonus: Rebates & Tax Incentives
Your local utility provider or state energy program may offer rebates ranging from $300–$3,000 for installing a qualifying Rheem heat pump water heater. Plus, thanks to the Inflation Reduction Act, you may be eligible for up to $2,000 in federal tax credits. That’s money back before you even start saving on your monthly bill.

The Bottom Line
Yes, a Rheem HPWH costs more upfront than a basic electric model—but the return on investment is clear. With energy savings, flexible operating modes, and available incentives, homeowners can start saving almost immediately and enjoy long-term value.
