Upgrade to an efficient heat pump water heater
If you currently heat your home's water with a traditional water heater, consider upgrading to a more energy-efficient heat pump water heater. Today's ENERGY STAR® certified heat pump water heaters are much more efficient than conventional electric water heaters.
How it works:
Because it pulls thermal energy from its surroundings instead of directly creating its own heat, an electric heat pump water heater is two to three times more energy efficient than a standard water heater.What to look for:
- Efficiency ratings. These include the Uniform Energy Factor (UEF) and First Hour Rating (FHR). A higher UEF indicates a more efficient water heater. FHR is the amount of hot water a water heater can supply in an hour if it starts with a full tank of hot water.
- The ENERGY STAR label. Certified heat pump water heaters are required to have a UEF greater than 2.0 and an FHR of over 45 gallons per hour.
- The right size for your home. A water heater with a high FHR may use more energy, so be sure to balance your household's hot water needs with your energy budget. To help you find the right water heater size based on your water use habits, visit the U.S. Department of Energy's Sizing a New Water Heater website.
- A reputable contractor to install your system.
Added benefits: Heat pump water heaters cool and dehumidify the air around them, so they are particularly useful in humid areas and basements.
Good to know: Heat pump water heaters are particularly cost effective in regions that stay within the 40-90°F temperature range year-round.
