“I would like to extend a thank you for your great work and professionalism during the JD2 heat pump start up. Your teams are a great example of what planning and hard work can accomplish. This is by far one of the easiest start-up processes that I have been through. Your teams have been with me from the design phase, installation phase and to completion. Knowing help was always just a phone call or text away takes a lot of pressure off me as an installer.”

The Department of Energy’s New Conservation Standards

Rheem Commercial water is here to help you navigate through the upcoming changes to enable you to make choices that fit your long-term needs. We’ve gathered the facts and removed the complexities behind the new standards to prepare you for the new changes scheduled to take effect on October 6, 2026. The new standards are a significant step towards energy efficiency impacting commercial gas water heaters.

Equipment	current	amended standards
Gas Fired Storage	TE = 80% SL = Q/800 + 110(Vr)1/2	TE = 80% SL = Q/800 + 110(Vr)1/2
Gas-Fired Instantaneous	TE = 80% SL (≥10gal) = Q/800 + 110(Vr)1/2	TE = 95% SL = 0.86*(Q/800 + 110(Vr)1/2)
Residential-Duty Commercial Gas-Fired Storage	Medium Draw Pattern UEF=0.6002-(0.0011xVr)	Medium Draw Pattern UEF=0.8702-(0.0011xVr)
Residential-Duty Commercial Gas-Fired Storage	High Draw Pattern UEF=0.6597-(0.0009xVr)	High Draw Pattern UEF=0.9297-(0.0009xVr)

What to Expect

Lower Carbon Emissions

According to the DOE, the adoption of these standards will reduce carbon emissions by 38 million metric tons between 2026 and 2055.
