This is because your outdoor heat pump will have a more difficult time creating enough warm air to heat your home. The ecobee asked this cause it assumes you have aux heat, is it electric? As long as the HP is producing some heat, it's more efficient to use the HP for whatever Btu's you can garner and allow the aux heat to be just that, auxiliary rather than primary. No-frills heat pump systems without the auxiliary heat capability sometimes make that feature an add-later option. Question. Components – Coils, Heaters, Motors, etc. 0. Press J to jump to the feed. The system is designed so that both can operate simultaneously. Question. In a package system the heat pump may run simultaneously with the AUX heat.

This is the heat you get when the compressor runs. 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. AUX heat mode is normal when: The temperature outside is below freezing. That will consume more energy and put out less heat, potentially leading to a much higher utility bill. Participate in over 40 different forums and search/browse from nearly 3 million posts. So in cold temperatures, the heat pump runs non stop to maximize your cheap heat but your home may remain a degree or two below your thermostat … It’s possible that, if the weather is especially cold, your heat pump could run near-constantly without there being an issue. Was that right? However, when the outside temperature is 32° F or below, your auxiliary heat will usually turn on automatically. The auxiliary heat pump should run more often when the temperatures outside dip below freezing. You might notice your heat pump runs constantly in cold weather. Compared to heat from the heat pump (COP 2.0 or 2.5) the auxiliary heat (COP 1.0) is quite expensive. As we mentioned above, heat pumps absorb heat from the outdoor air and then move that heat indoors. Posted by 2 years ago. Allow heat pump and auxiliary to run simultaneously? Aux heat comes from the same heat source as emergency heat, but aux heat works together with your heat pump, so it’s less expensive than emergency heat. Scenario 1 – Cool Air Blowing from Registers. Having both heat sources running is not a bad thing - it’s for those really cold days where it knows your primary heating source won’t cut it so it needs supplemental heat. This is set at a default 35F (1.7C), so the heatpump will not be used when the weather outside is below 35 degrees Fahrenheit and only aux heat will be used in this case. Electricity is inherently less energy efficient than running the HP.

Knowing the difference between your heat pump’s auxiliary heat and emergency heat will help address the question from above. The same goes for warmer climates. Once it gets close to the actual setpoint, the aux heat de-energizes and the heat pump mode of the system remains operating to generate heat and will shut off if the temperature is satisfied. In this setting, the heat pump will lock out before the fossil fuel auxiliary heat comes on; eliminating the need for a dual fuel kit. Close. 1In heat pump mode, this system setting is also the auxiliary heat setting. The #1 question asked by NEW MEMBERS. Post photos, respond to polls and access other special features. Meanwhile the heat pump has been running non-stop throughout this time to maximize the cheap heat. Heat pump running constantly in winter. That's why it is called auxiliary heat it supplements the primary heat. Auxiliary heat can handle more extreme temperatures since it uses electric heat strips. If YOU want change, YOU have to first change. Some heat pumps also have auxiliary heat, an additional stage of heating that is typically used when the heat pump compressor can’t keep up with cold weather conditions. Most heat pump thermostats bring on the back up heat when the temperature difference between the room and that thermostat setting is 3 degrees or more.
