Heat pumps serve the dual purpose of space heating and cooling, as an alternative to the conventional setup of separate units. Although heat pumps can now be used in places with harsh winters, the emergency heat option on the thermostat isn’t meant for providing additional warmth. It’s a heating backup to turn on if your heat pump fails, which will keep you warm while waiting for the HVAC company to complete repairs. Here’s what you need to know about it.

What Is Emergency Heat?

Emergency heat is a setting that can be used when the outdoor unit breaks down or gets damaged. It serves as a backup heating source for your home if you don’t have a furnace or boiler as a secondary system. Some homes have a backup heat system that is powered by electricity, gas, oil, or hot water that automatically switches on when the heat pump is unable to maintain an acceptable indoor temperature. When this setting is turned on, it locks out the outdoor unit and relies on the fan coils of the indoor heat pump system to provide needed warmth until your HVAC company finishes repairs.    

How to Switch It On

The emergency heat setting has to be manually activated, so it won’t switch on even if the heat pump thermostat registers low temperatures. Once turned on, an indicator will light up to let you know that you’re on emergency mode. It will cut off any signal from the outdoor heat pump and run the system to meet your heating requirements.

Why You Should Avoid Running It for Prolonged Periods

If you notice that your rooms are colder than usual, check your unit for damage and call an HVAC company for emergency repairs. Keep in mind that emergency heat consumes more energy than your usual system, resulting in an unusual spike in your utility expenses. It’s not cost-effective to switch it on to bump up the temperature faster or use it frequently. As the name implies, only use it in case of an emergency.
