Abstract
The unsatisfactory performance of the heat pump water heaters (air-to-water) in colder ambient temperatures is the main obstacle to the expansion of the residential market for this device. On the other hand, the price increase of natural gas in the 1980's encourages retrofitting or replacing the existing gas-fired water heaters. The present study examines the possibility of retrofitting the gas-fired water heater with a heat pump water heater. The result of the investigation on the thermodynamic and economic performance of a water heater system comprised of a heat pump water heater and a gas-fired water heater is presented in this paper.
