Question 1

How much can I save by upgrading my water heater?

Accepted Answer

ENERGY STAR certified gas storage water heaters use about 10% less energy than standard models and can save a four-person household hundreds of dollars over the unit's lifetime. Actual savings depend on your current water heater efficiency, household size, and local fuel prices.

Question 2

How do I know if a water heater is efficient?

Accepted Answer

Look for the UEF (Uniform Energy Factor) rating on the Energy Guide label—higher numbers mean less energy wasted. ENERGY STAR certified gas storage water heaters (≤55 gallons) must have a UEF of at least 0.81, which is a good baseline for efficiency.

Question 3

Why does my location matter?

Accepted Answer

Your location determines how cold the water is when it enters your home. In colder climates, water mains are cooler, so your water heater works harder to reach the target temperature (typically 120°F). This means both higher baseline energy use and greater potential savings from an efficient upgrade.
