ENERGY STAR heat pump water heaters: typical energy use

601 heat pump water heater listings currently carry the ENERGY STAR certification — electric heat pump water heaters certified under ENERGY STAR. Here is the typical range and the most efficient model on record, straight from the U.S. EPA's own product-finder dataset.

How to read this page

Como ler este número

What the number measures

This is the annual energy use reported under the U.S. DOE test procedure for heat pump water heaters — a standardized lab test, not a measurement from a real home.

De onde vem o dado

data.energystar.gov, collected 2026-10-09

Figures come straight from the U.S. EPA's own Socrata dataset (dataset v7jr-74b4), under the EPA Data License. Last model added to this category: 2026-10-01.

Cuidado

ENERGY STAR only covers certified models

This list only includes heat pump water heater models the manufacturer submitted for certification — it is not every heat pump water heater sold in the U.S., and a model being absent does not mean it is inefficient. Figures are per year, under lab conditions; your own bill depends on size, settings and how much you use it.

How big is the certified heat pump water heater market?

As of 2026-10-01, 601 heat pump water heater listings carry the ENERGY STAR certification — electric heat pump water heaters certified under ENERGY STAR. It is a smaller, more specialized list than categories like refrigerators or dishwashers, which makes individual model specs more worth comparing one by one.

What is a typical heat pump water heater annual energy use?

Certified heat pump water heaters sit in a fairly narrow band: from 643 kWh to 1,741 kWh a year, averaging 1,106 kWh a year. A narrow spread like this means the ENERGY STAR mark alone does not tell models apart as much — size and features matter more than the label here.

Which certified heat pump water heater uses the least energy?

The most efficient model in the dataset is the Richmond 10CE40-HP5U15, at 643 kWh a year — close to the catalog minimum of 643 kWh. "Most efficient" here is a single data point, not a buying recommendation: capacity, features and price matter too.

ENERGY STAR

ENERGY STAR is a U.S. Environmental Protection Agency (EPA) program that certifies appliance models meeting a set energy-efficiency threshold. Certification is voluntary for manufacturers and does not cover every model on the market.
