The Department of Energy has decided to delay the effective date of new energy conservation standards for gas-fired instantaneous water heaters. Originally, the rule was set to be enforced on March 21, 2025, but it is now postponed to May 20, 2025. This delay aligns with a Presidential Memorandum that called for reviewing such rules. The compliance date for these standards, however, remains unchanged at December 26, 2029.
Simple Explanation
The government decided to wait a bit longer before starting new rules to save energy with certain water heaters, moving the start from March to May, but you still have to follow the new rules by the end of 2029. Some details about why they are waiting aren't really clear.
