How the Department of Energy’s New Efficiency Rules Could Change the Tankless Water Heater Market

Understanding the DOE’s Proposed Efficiency Standards for Tankless Water Heaters

The U.S. Department of Energy (DOE) has proposed new efficiency standards for gas-fired tankless water heaters. While this might seem like a step forward, the proposed regulations have sparked concerns across the industry.

What’s Changing?

The DOE suggests raising the efficiency standard for tankless water heaters to over 91%, a level that non-condensing tankless models cannot meet due to technological limitations. In contrast, traditional tank-style water heaters are required to achieve only 70% efficiency, creating an uneven playing field. The result? A likely restriction on the availability of tankless water heaters, an already environmentally friendly option.

Impacts on Consumers

If implemented, these changes could limit consumer access to affordable, efficient tankless water heaters. This would disproportionately affect middle-income households and small businesses. With fewer options, homeowners may face higher energy costs and reduced appliance lifespans, negating the environmental benefits these standards aim to achieve.

Rinnai’s Response

Rinnai America Corporation, a leader in tankless water heater manufacturing, has voiced its concerns about these proposed standards. Frank Windsor, president of Rinnai America, highlights that these rules could jeopardize American jobs and consumer choice. Rinnai is advocating for a balanced approach that supports energy goals without compromising affordability and accessibility.

Why It Matters

Tankless water heaters are not only more compact but also provide continuous hot water and have longer lifespans than traditional models. By restricting access to these products, the DOE’s proposal might inadvertently hinder advancements in energy efficiency and environmental sustainability.

Get Involved

Public comments on the DOE’s proposal are encouraged, allowing individuals to voice their opinions and advocate for fair standards that benefit both consumers and the environment.
