Criteria Development History

DOE last reviewed water heaters in 2003. After analyzing the market, the potential energy savings and economics of the various technologies, and considering feedback from stakeholders, DOE decided not to establish an ENERGY STAR criteria for domestic water heaters at that time. A letter PDF (143KB) from Richard Karney, the Department’s ENERGY STAR Program Manager explains the rationale for this decision.

Tax Credits on Water Heaters

Tax credits are available on new water heaters in 2006 and 2007 under the Energy Bill. For more information, see Federal Tax Credits for Residential Energy Efficiency.
