The proposed standards would require commercial water heaters to incorporate condensing technology.

The US Department of Energy (DOE) has proposed new energy efficiency standards for commercial water heating equipment, including gas storage, tankless water heaters and gas boilers. The proposed standards would require commercial water heaters to incorporate condensing technology, which significantly reduces energy consumption by extracting additional heat from the combustion process. Energy efficiency is a key part of President Biden’s plan to cut climate pollution while saving money.

“Water heating accounts for a significant portion of household energy costs and carbon emissions,” said Kelly Speakes-Backman, principal assistant assistant secretary for energy efficiency and renewable energy. “Upgrading commercial water heater technology will reduce energy costs for schools, hospitals and small businesses while removing carbon and methane from our atmosphere.”

If finalized, the proposed standards would save businesses and operators $140 million a year in operating costs. Over the next 30 years, the new standards are expected to generate savings of $2.4 billion, with an average life cycle savings of $301 for the operator of a commercial building from a water heater to gas accumulation. According to the Energy Information Administration, gas water heating accounts for 18% of natural gas consumption in commercial buildings, primarily due to inefficient, non-condensing water heating equipment that allows excess heat to escape.

In addition to projected cost savings over 30 years, the new standards will reduce carbon emissions by an amount equivalent to the annual emissions of 4.8 million homes. The new standards will also reduce methane emissions by an amount equivalent to the annual emissions of 2.3 million gasoline-powered cars.

If implemented within the timelines proposed by the DOE, the new standards will become effective in 2026. Next month, the DOE will host a public meeting via webinar to seek public comment on the proposed regulations.

The DOE’s Building Technologies Office implements minimum energy conservation standards for more than 60 categories of appliances and equipment.
