How can I find ENERGY STAR® certified solar water heaters?

There are several ways to find ENERGY STAR certified solar water heaters:

  • EPA ENERGY STAR Certified Product List. This list is maintained by the U.S. EPA and contains information on ALL ENERGY STAR certified water heaters (gas, electric and solar).
  • ICC-SRCC Listing Directory. Each manufacturer with solar water heaters certified to ENERGY STAR by ICC-SRCC is listed here. Look for the blue ESTAR mark and click on the listing to view a list of all certified models from that manufacturer.
  • ICC-SRCC OG-300 Directory. Each OG-300 system that also holds ENERGY STAR certification is identified with a yellow star.
