A heat pump system includes a heat pump and an auxiliary heat source. A heating coefficient of performance is determined for the heat pump based on ambient outdoor air temperatures, and the heat pump is operated to heat a process fluid an output temperature based on the heating coefficient of performance and a reference heating coefficient of performance. The auxiliary heat source can be operated to bring the process fluid to a target temperature for heating a load, with the target temperature being a function of the ambient outdoor air temperatures.
