Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Department of Energy relating to "Energy Conservation Program: Energy Conservation Standards for Consumer Gas-fired Instantaneous Water Heaters".

This measure cancels a Department of Energy rule that set new energy-efficiency standards for gas-fired “instant” (tankless) water heaters. The rule aimed for the highest efficiency that DOE said was feasible and made economic sense. By disapproving the rule, those updated standards do not take effect for these water heaters .

In everyday terms, this keeps the current requirements in place instead of moving to stricter ones for gas tankless water heaters. It applies to the rule the DOE submitted on December 26, 2024, about energy conservation standards for these products .

• Who is affected: Makers, sellers, and buyers of gas-fired instantaneous (tankless) water heaters .
• What changes: The newer, stricter efficiency standards are blocked; existing standards remain in place .
• When: It targets the DOE rule submitted on December 26, 2024 .
