The water-to-air heat pump might not need auxiliary heat because the water can be at relatively constant temperature all winter.

Question

Quizplus · Accepted Answer

As long as the water source for the heat pump remains at a relatively constant temperature, the heat pump should be able to provide heating without needing auxiliary heat. This is because the heat pump can extract heat from the water source regardless of the outside temperature. However, if the water temperature drops too low or fluctuates too much, auxiliary heat may be necessary to supplement the heat pump's output.
