2026 Indiana Heat Pump Water Heater Incentives: Indiana Energy saver Program & Utility Stacking Guide

Indiana

Benefits of an ENERGY STAR® certified heat pump water heater

Heat Pump water heaters are ~70% more efficient that standard electric water heaters and save the average households in Indiana $436* every year on their electric bills. A Heat Pump water heater is the only water heater that quickly pays for itself (payback) with the energy savings. 

Heat Pump water heaters pull heat from the surrounding ambient air and pass it on to the water. They operate like your refrigerator, just in inverse. They help dehumidify the basement. It is much more efficient to transfer heat than to create heat.

Heat pump water heaters get installed exactly like a standard electric water heater. The only difference is the need for a condensate drain nearby (or use a condensate pump to a sink) and a minimum of ~700 cubic feet (i.e 10′ x 10′ x 7′) around the water heater (consult the specific manufacturers’ Use & Care manual, louvered doors and air ducting options exist for smaller enclosures).
To operate properly Heat Pump water heaters cannot reside on a recirculation system that runs continuously. Install a timer or a motion sensor.

Annual energy savings of 2,743 kWh/year and average IN residential electricity cost of 15.91 cts/kWh. Savings may vary.
