61 80 gal and up Electric Water Heaters, Ranked by Running Cost

Electric water heaters (including heat pump models), 80 gal and up or more, sold in the US. Ranked cheapest to run first, estimated at 18.31¢/kWh (July 2026).

← All electric water heater sizes

All models here are heat pump water heaters — ENERGY STAR does not appear to certify standard electric-resistance tanks, only the far more efficient heat pump type. "Split system," "120V integrated" and "240V integrated" below are different installation types, not efficiency tiers.

61 ENERGY STAR certified models, from about $202 to $319 a year in electricity to run at the US average rate. See how we calculate running costs.

Estimated running cost = annual kWh × 18.31¢/kWh (July 2026 US average). Your own rate may be higher or lower — check your bill. ENERGY STAR figures are lab-test results; real-world use varies. Gas and propane water heaters are not included — their energy figures cover electronics only, not the fuel that heats the water. This list includes discontinued and not-yet-sold certified models.
