Advanced commercial water heating

More efficient and resilient water heating
Commercial building owners and operators can increase performance, enhance resiliency, and reduce operating costs by serving their gas water heaters with either electric or gas heat pumps. Using outdoor heat pumps to heat water before it enters the indoor tanked gas water heater(s) reduces the demand on the less-efficient equipment. Whether incorporating a gas or electric heat pump, this holistic system is far more efficient than traditional water heater and storage tank designs.
Two approaches
Gas heat pump with gas water heaters
Provides efficient, resilient hot water by incorporating an outdoor gas heat pump with gas water heater(s) in a
unified system.

Dual-fuel water-heating system
Provides efficient, resilient hot water by incorporating an outdoor electric heat pump with gas water heater(s) in a unified system.

Benefits
-
Increases efficiency

Featured Project
The River Haven project serves as the latest case study in the program’s ongoing efforts to optimize the region’s water heating efficiency by integrating more efficient technologies into gas and electric commercial and multifamily buildings. The system will be metered and monitored for one year to track the performance and savings of this dual-fuel configuration.
