Development of a residential air-source ammonia-water absorption heat pump designed to operate in the heating mode only and deliver its output as hot water is described. A prototype unit was developed and three life test and three field test units will be operating in a northern climate during the '81/'82 winter. Prototype specifications are 50,000 Btuh input, 125/sup 0/F supply water, 105/sup 0/F return water, COP 1.25 at 47/sup 0/F ambient and 1.12 at 17/sup 0/F ambient.
