The Advanced Commercial Water Heating program works to accelerate the development and market availability of high-efficiency commercial water heating systems, with a focus on commercial gas heat pumps and other advanced configurations for commercial and multifamily buildings. These technologies have the potential to significantly reduce energy consumption while providing reliable hot water.

The program is working to overcome barriers such as design complexity, high first costs, and low market awareness through product testing, performance validation, and manufacturer engagements. It is also working with building owners and the supply chain to provide guidance on design and installation practices. Through these efforts, the program aims to position gas heat pumps and dual-fuel solutions as viable, efficient options for commercial water heating that deliver energy savings and cost benefits.
