Understanding Emergency Heat on Your Thermostat: A Guide for Homeowners


As the temperatures drop and winter sets in, it's crucial for homeowners to understand the various settings on their thermostats to ensure optimal comfort and efficiency.


One such setting that often raises questions is the "Emergency Heat" option.


In this blog post, we'll explore what emergency heat is on your thermostat, how it differs from regular heating, and when it's appropriate to use.


What is Emergency Heat?

Emergency Heat is a feature found on many HVAC systems. It is designed to provide a supplemental heat source when the primary heating system is not functioning correctly or efficiently. Unlike the regular heating mode, which may use a heat pump or electric resistance heating, emergency heat typically relies on a backup heating element, such as electric resistance coils.


When to Use Emergency Heat:

  1. Primary Heating System Malfunctions: The most common scenario for using Emergency Heat is when your primary heating system malfunctions. If your heat pump or furnace is not operating correctly, switching to Emergency Heat can provide a temporary solution until the primary issue is resolved.

  2. Extremely Cold Weather: In regions where winters can be extremely cold, the efficiency of heat pumps may decrease. When the outside temperature drops significantly, and your heat pump struggles to extract heat from the air, activating Emergency Heat can ensure a more reliable and efficient heating source.

  3. Quick Warm-Up: Emergency Heat can be used when you need a quick warm-up in your home. Since it relies on electric resistance heating, it can generate heat more rapidly than some heat pumps, providing a faster response in chilly conditions.

While Emergency Heat is a valuable feature, it's essential to use it judiciously. Here are a few considerations:

  1. Energy Consumption: Emergency Heat tends to consume more energy than the primary heating system. Therefore, it's advisable to use it sparingly and address any issues with the main heating system promptly.

  2. System Inspection: If you find yourself frequently relying on Emergency Heat, it's a sign that your primary heating system may need inspection and maintenance. Regular HVAC maintenance can help prevent emergency situations.

  3. Thermostat Settings: Be familiar with your thermostat settings. Some thermostats have a specific "Emergency Heat" mode, while others may automatically switch to it when needed. Consult your thermostat manual for guidance.


Understanding the purpose and appropriate use of Emergency Heat on your thermostat can help you maintain a comfortable home environment, especially during cold winter months.


If you have concerns about your heating system or thermostat settings, don't hesitate to consult with a professional HVAC technician for expert advice and assistance.


Stay warm and cozy all winter long!
