What is auxiliary heat in an Ecobee system?
Auxiliary heat refers to a secondary heating source used by heat pumps to maintain a comfortable indoor temperature when outdoor conditions are extremely cold. In Ecobee systems, it typically kicks in when the heat pump is unable to efficiently warm the home on its own. This may happen in very cold weather or during peak heating demands.
The auxiliary heat element is usually electric, and it provides additional warmth to bridge the gap until the main system stabilizes. Understanding when and how auxiliary heat operates is essential for effective climate control and for troubleshooting any issues that may arise.
Why isn’t my auxiliary heat turning on?
Several factors can prevent auxiliary heat from activating, including incorrect thermostat settings, wiring issues, or even a malfunctioning heat pump. Ensure that the thermostat is set to a temperature that requires the auxiliary heat to kick in. An overly low setting will cause it to remain inactive.
