Project Term: October 1, 2013 - September 30, 2016

Project Objective

The objective of this project is to develop a gas-fired absorption heat pump water heater for the commercial market, capable of an energy factor greater than 1.0 as determined by the standard rating procedure for storage water heaters. The cost premium over conventional gas-fired storage water heaters should be kept to a minimum.

Project Impact

According to ORNL, the technology has the potential for 40% energy savings over other gas-fired water heaters. Fully deployed, this would provide up to 0.18 Quads of primary energy savings per year. Additionally, this would be using nontoxic working fluids with zero GWP and zero ODP.
