Auxiliary (AUX) heat is a second source of heat that comes with some heat pump systems. If the auxiliary coolant pump is inoperative, the customer might notice reduced heater performance at low speeds and at idle. The auxiliary heat (electric resistance heat, or back-up heat) is minimized since it is more expensive. Heat pumps are the main source of heat most of the time, but they aren't efficient when it's very cold outside. Emergency Heat, also known as “auxiliary heat”, is the second stage of heat that your thermostat runs on when the temperature is too cold for your heat pump to extract heat from the outside.
