Gas Water Heating Initiative


This Initiative works to increase market penetration of high efficiency commercial water heaters. Efforts center on developing specifications for cost-saving equipment and ultimately, increasing the number of manufacturers, wholesalers, and installers that promote high efficiency equipment to their customers. The goals of the Initiative are met as:

  • high efficiency equipment becomes easily available from manufacturers, wholesalers, and distributors
  • high efficiency equipment is widely promoted to installers and key commercial building decision makers
  • demand for high efficiency from building owners, managers, and energy managers increases
  • high efficiency equipment is included in new construction building design plans by builders, design engineers, architects, or developers
  • promotion, sales, and installation by contractors of high efficiency equipment in commercial buildings increases

Note: For the purposes of this Initiative, high efficiency commercial water heaters are defined as those that achieve condensing levels of efficiency.


Members depend on CEE to funnel information from industry partners and federal agencies on likely opportunities as they continue to look for savings opportunities in applications like racked tankless water heaters for commercial applications.

Increasing the availability of efficient products in the marketplace and encouraging consumer uptake of those products are essential aspects of energy savings. Given the large share of energy used for heating water in food service, commercial kitchens remain a key focus.

How to Participate

As with all CEE initiatives, participation in the High Efficiency Natural Gas Commercial Water Heating Initiative is voluntary. Initiative participation requirements are formulated to focus efforts on market impacts:

  • incorporate the CEE efficiency specifications for storage or tankless water heaters—or both—in an incentive program using at least one of the specification tiers for water heaters
  • undertake at least one of the outreach activities to the supply channel
