Gas storage and tankless water heaters that have earned the ENERGY STAR® label are independently certified to help you reduce your energy usage, save you money and help prevent climate change.

If every gas water heater sold in the United States was ENERGY STAR® certified, energy savings would grow to almost $1.2 billion annually. These savings are equivalent to preventing about 10 billion pounds of greenhouse gas or the emissions of 900 thousand cars annually.*

Uniformed Energy Factor (UEF): The UEF rating method improves the industry's ability to define consistent standards for measuring energy efficiency performance. The higher the UEF value is, the more efficient the water heater.

Key Benefits

To improve efficiency, the latest technologies are deployed in ENERGY STAR® certified gas water heaters:*

  • Storage water heaters use better insulation, heat traps, and more efficient combustion systems.
  • Tankless water heaters employ a secondary heat exchanger to extract more heat from the combustion process.
