Gas-fired absorption heat pump applied for high-temperature water heating: Parametric study and economic analysis

•Gas-fired absorption heat pump for high-temperature water heating is proposed.•The system produces hot water above 90 °C with primary energy efficiency of 1.38.•Temperature lift is 75 °C that is much higher than the single-effect system.•Energy saving potential is 36.7–43.5% compared to the gas-fir...
