Knowing the difference between your heat pump’s auxiliary heat and emergency heat will help address the question from above. Our 20th year anniversary is May 21, 2020. Auxiliary heat is less energy-efficient than your heat pump, and it is meant to only run for short periods of time when temperatures drop. 3. For example, if you live in an area with long, cold winters, a heat pump will run more than in temperate climates.

COP: COP or Co-efficient Of Performance is a way of describing a heat pump's efficiency. This is allowable because the indoor coil (condenser in the heating mode) is upstream of the AUX heating elements. Compared to heat from the heat pump (COP 2.0 or 2.5) the auxiliary heat (COP 1.0) is quite expensive. Electricity is inherently less energy efficient than running the HP. AUX heat mode is normal when: The temperature outside is below freezing. This wire is usually found in the W2/AUX connector on your thermostat. If your heat pump is constantly running, there are likely three main causes: Unusually cold weather: Heat pumps are designed to work much more gradually than a furnace.
