Robur Heat Pump Field Trial

The Robur air-source gas absorption heat pump (GAHP) has been identified as an efficient product for water and space heating in buildings in the Northwest. Utilization of a heat pump to heat water allows for a coefficient of performance that exceeds one, however actual heat pump performance varies throughout the year and is dependent on ambient air conditions and outlet water temperatures.

To evaluate field performance in the Northwest, user acceptance, reliability and avoided cost of fuel, the Northwest Energy Efficiency Alliance (NEEA) contracted with Energy 350, Inc. to install and monitor two Robur GAHP A units in a large senior living facility. This report summarizes the field study results and findings over the 2018/2019 heating season.
