The CEE Directory lists high efficiency water heaters which meet the specifications in the CEE High Efficiency Residential  Gas Water Heating Initiative. The initiative was launched in January 2008.

In October 2014, CEE replaced its spreadsheet-based Qualified Product List with a web-based search using the CEE Directory. This automated search uses data from AHRI to identify high efficiency equipment that meet CEE specifications. For older lists, please contact George Chapman.
