The Role of Auxiliary Heat

Learn More About Auxiliary Heat

To truly understand the importance of auxiliary heat in modern heating systems, we must first grasp the concept of this function. Auxiliary heat, also known as “second-stage heat,” serves as a supplementary source of warmth when your primary heating system, typically a heat pump, struggles to meet the desired temperature settings.

When Does Auxiliary Heat Typically Activate?

  1. Extreme Cold: Auxiliary heat often activates during extremely cold weather conditions, such as frigid winter nights. When the heat pump alone can’t extract enough warmth from the chilly outdoor air, auxiliary heat steps in to bridge the gap.
  2. Temperature Differential: When the temperature differential (the difference between the thermostat setting and the current indoor temperature) is significant, auxiliary heat helps speed up the heating process. This ensures that your home reaches your desired temperature promptly.

How to Fix Ecobee Auxiliary Heat Running Too Long?

Your Ecobee thermostat’s auxiliary heat is running too long, which can lead to higher energy bills and reduced system efficiency.

  • Check the Temperature Setting: Make sure your thermostat is set to a reasonable temperature. Sometimes, if you set the temperature too high, the auxiliary heat may run longer to reach that temperature. Consider lowering the setpoint a few degrees to see if that reduces the runtime.
  • Update Firmware: Ensure that your Ecobee thermostat’s firmware is up to date. Manufacturers release updates to improve system efficiency and address bugs. You can usually update the firmware through the thermostat’s settings or the associated mobile app.
  • Adjust Temperature Differential: Ecobee thermostats allow you to adjust the temperature differential setting. This setting determines how much the temperature can vary from your desired setpoint before the auxiliary heat kicks in. You can try widening the differential to prevent the auxiliary heat from turning on too quickly. However, be careful not to make it too wide, as it may lead to discomfort in your home.
  • Check for Drafts and Insulation: Ensure that your home is well-insulated and free of drafts. Cold air entering your home and warm air escaping can cause your heating system to work longer and harder. Seal any gaps around doors and windows, and consider adding insulation where needed.
  • Inspect and Clean Filters: Dirty air filters can restrict airflow, making your heating system less efficient and causing it to run longer. Check and clean or replace your air filters regularly, following the manufacturer’s recommendations.

Seeking Professional Assistance

When it comes to addressing issues with your Ecobee thermostat, particularly when the auxiliary heat runs excessively, the do-it-yourself approach can work wonders in many cases. However, there are instances where professional assistance becomes essential.
