What is the Emergency Heat Switch on my Heat Pump Thermostat Used for?
Wednesday, December 14, 2016
Emergency Heat

Heating and air conditioning systems can be a bit of a mystery outside of their normal daily function. For example, if you have a heat pump, you might be wondering what the emergency heat switch on the thermostat does. You’ve come to the right place! Read on for the information you need.

Your Heat Pump in Cold Weather

A heat pump is designed to extract heat from one area and transfer it to another. In the winter your heat pump will warm your home by pulling heat from the outside and moving it inside. One of the benefits of a heat pump is that it moves heat instead of generating heat, so it’s incredibly efficient.

What Is Emergency Heat?

In our mild climate, the primary heating unit of your heat pump is sufficient for keeping your home warm in the winter. What happens when we get a cold snap? That’s when the emergency heat source comes into play. 

When there isn’t enough heat in the air outside for the heat pump to adequately warm your home, you’ll need to use a secondary heat source. This secondary source is your emergency heat, and it is often electric resistance heat.

When Should You Use Emergency Heat?

Setting your thermostat to Emergency Heat will make the system bypass the heat pump and go to the secondary source. The name is telling: only use it when necessary. Why? Because it’s an expensive way to keep your house warm. But if the temperatures outside plummet, you’ll need to use it. 

No matter the temperature outside, you can keep your home warm in the winter. For all the information you need on your heating and air conditioning, no matter what type of system you have, contact our friendly team at All City Heat and Air today.

They serviced our a/c unit as well as purchasing a service agreement. They were fantastic! They were amazing when it came to responsiveness. Everything was done as they said it would be. They were just as good and professional as the larger heating and a/c companies who were going to charge me a lot more. I would refer them without hesitation.
