EM Heat vs. Heat: Understanding Thermostat Settings & HVAC Differences

Are you confused by the "EM Heat" or "Emer Heat" setting on your thermostat? It's a common point of confusion for many homeowners. Knowing the difference between EM heat and standard heat is crucial for efficient heating and cost savings, especially during the colder months. This article will break down the distinction, explaining when and why you might use emergency heat. Understanding these settings contributes to your overall HVAC knowledge and helps you manage your home's comfort and energy consumption properly.

EM Heat vs. Heat: The Basics

Your heat pump system has two primary heating modes: standard heat and emergency heat (EM heat). Standard heat uses the heat pump to draw heat from the outside air and transfer it indoors. When the temperature drops significantly, standard heat may struggle. That's when EM heat, usually powered by electric resistance coils, kicks in. EM heat provides immediate, powerful heating to keep your home warm, but it typically uses more energy.

When to Use EM Heat

EM heat should be reserved for specific situations. Use EM heat:

• When the heat pump malfunctions.
• During exceptionally cold weather when the heat pump can't keep up.
• When the system is being serviced.

Leaving EM heat on for extended periods can significantly increase your electricity bill.
