The DOE’s 2026 high efficiency water heater rule—sometimes called the “gas water heater ban”—is coming fast. Learn how Intellihot’s tankless, commercial-grade water heating solutions already meet the new standards.
In 2024, the U.S. Department of Energy (DOE) finalized new regulations aimed at increasing the energy efficiency of water heaters. These standards, which go into effect in 2026, are a major step in reducing greenhouse gas emissions and lowering utility bills for millions of Americans.
Often referred to in media headlines as a “gas water heater ban,” this mandate doesn’t outright prohibit all gas water heaters—but it does require them to meet much stricter efficiency standards. As a result, most traditional tank-style gas water heaters will no longer comply unless manufacturers make significant updates.
While the DOE isn’t banning gas water heaters entirely, the new energy efficiency standards effectively phase out many conventional models. Gas-powered units will effectively need to use condensing technology to meet the 2026 requirements—a feature that adds cost and complexity for manufacturers and installers.
This shift is part of a larger national trend toward electrification and decarbonization of residential and commercial buildings. For homeowners and facility managers alike, the regulation has prompted an urgent question:
What now?
At Intellihot, we didn’t wait for a government mandate to develop water heating systems that are cleaner, smarter, and more efficient. Our tankless, on-demand water heaters are already designed to meet or exceed the DOE’s 2026 efficiency standards.
Here’s how we stand out:
Intellihot units heat water only when it’s needed, eliminating the energy losses associated with traditional tank systems.
Our gas-fired tankless systems are built with advanced condensing technology, delivering exceptional thermal efficiency—often 96% or more.
Looking to go fully electric? Intellihot’s electric tankless water heaters offer scalable, high-performance solutions without the carbon footprint of fossil fuels.
From small commercial buildings to large-scale hospitality operations, our modular systems provide hot water on demand—with zero storage tanks and minimal installation footprint.
The upcoming water heater regulations are not just about compliance—they’re about building a smarter, more sustainable infrastructure. Intellihot’s technology is already helping thousands of businesses reduce energy costs, cut carbon emissions, and future-proof their properties.
Whether you’re a facility manager, mechanical contractor, or sustainability officer, now is the time to act. Don’t wait for the 2026 deadline to start replacing outdated equipment.
You don’t need to wait for a complete water heating system failure at a commercial property. Replacing ancient or unreliable water heating technology can be beneficial to you and your customer right away. Here are 5 signs before a complete failure that might indicate that a facility is ready to upgrade its water heating system to Intellihot’s cutting-edge technology:
