DOE Finalizes Energy Conservation Standards for Consumer Gas-Fired Instantaneous Water Heaters
January 2, 2025 | 1 minute read
On December 26, 2024, the Department of Energy (DOE) issued a final rule amending energy conservation standards for consumer gas-fired instantaneous water heaters (GFIWH). Earlier this year, DOE finalized a new energy efficiency standard for other consumer water heaters but did not finalize the proposal for GFIWH.
Key Highlights of the Final GFIWH Rule
Scope of Coverage:
Applies to gas-fired instantaneous water heaters with less than 2 gallons of effective storage volume and input ratings greater than 50,000 Btu/h.
Standards are expressed using the Uniform Energy Factor (UEF), transitioning from the older energy factor (EF) metric.
New Standards:
UEF levels are established based on draw patterns (Very Small, Low, Medium, High). For example:
Very Small draw pattern: UEF = 0.89
High draw pattern: UEF = 0.93
Compliance Date:
Compliance is based on the date of manufacture, and this new requirement will apply to all GFIWH manufactured after December 26, 2029.
