Thousands of Tennesseans have new planet-friendly water heaters in their homes after taking advantage of an incentive program that will likely help them save even more money down the road.

Upgrading to heat pump water heaters can save homeowners hundreds of dollars a year on energy bills. Per the Department of Energy, water heating is responsible for nearly 20% of home energy use. However, heat pump water heaters are much more efficient appliances than traditional units. 

In March, the Tennessee Valley Authority restructured its incentive program and began offering consumers a $1,300 retail rebate for heat pump water heater installations, according to Homepros. The change led to "roughly 1,800 heat pump water heater installs within six months." 

Residents can anticipate another adjustment to the incentive program in 2026. Per Homepros, the rebate will drop to $900 dollars per unit in mid-February. However, TVA residential rebate program manager Bethany Klitch said the company still wants to install 4,000 units this year. 

Instead of generating heat directly, heat pump water heaters use electricity to move heat around, which makes them two to three times more energy-efficient than traditional options, according to the DOE. 

If you're thinking about upgrading, Cala has customizable smart heat pump water heaters that can help you lower your energy bills. Cala appliances optimize water heating based on your home's needs. 

There are also rebate programs available for those worried about the cost of a Cala heat pump water heater. Depending on your location, you may be eligible for up to $1,750 in incentives.

Another factor for homeowners to take into account when installing heat pump water heaters is longevity. Per Consumer Reports, a heat pump water heater has a lifespan of 13-15 years. Meanwhile, a conventional water heater usually lasts between 10 and 12 years.
