Please reference all rebate requirements prior to installation to ensure eligibility.

Notice: Starting June 12, 2017, the Department of Energy (DOE) implemented new energy efficiency standards for water heaters. The old metric was Energy Factor, or EF. The new metric is UEF or Uniform Energy Factor. They are not the same.

Because the UEF metric is new, customers may purchase a water heater that was certified with an EF rating criteria. Models that were rated with EF will be honored in our rebate program through 12/31/2017. After this date, all rebates will be issued based on the AHRI database certification UEF criteria.

To apply for a rebate, download and fill out the water heating equipment rebate application.

Funding is limited and can change or end at any time. Applications will be processed on a first-come, first-served basis. The program application must be received within 60 days of installation.
