The Emergency Heat Switch On Heat Pumps — What Is It and How Does It Work?
Heat pumps are an essential component in most modern heating and cooling systems. They are designed to move heat from one location to another, providing a comfortable indoor temperature in any weather condition. Heat pumps are efficient and cost-effective, making them a popular choice for homeowners in North Carolina.
First, How Does a Heat Pump Work?
A heat pump provides comfort by extracting heat from the cold air outside. A gas furnace generates heat, but a heat pump transfers heat from one place to another. But what happens when temperatures are too low that there isn’t enough heat energy to draw from?
On average, a heat pump can maintain a 30-degree temperature difference between the inside and outside of a home. For example, if it is 40 degrees outside, the interior of the home can be heated to a comfortable 70 degrees. However, as temperatures drop below 35 degrees, a heat pump's efficiency decreases, and it will automatically switch to auxiliary heating to supplement its heating capabilities.
Auxiliary Heat Supports Your Heat Pump
Auxiliary heat is a feature that supports a heat pump’s operation by generating warmth through electric resistance heating coils, similar to baseboard heating. (Some heat pumps can utilize natural gas or propane for the auxiliary heat.) If there isn't enough heat energy outside to reach the desired temperature, a heat pump with this feature will automatically turn on the supplemental heating. When outside temperatures rise, the auxiliary heat source will turn off automatically. It is important to note that auxiliary heat is different from manually utilizing the Emergency Heat switch.
What Is An Emergency Heat Switch?
The emergency heat switch is a feature found on most heat pumps that provides an alternative source of heat when the primary heat pump system is not operating efficiently. The switch is also known as the “emergency heat” or sometimes “auxiliary heat” setting, and it is typically located on the thermostat.
How Does The Emergency Heat Switch Work?
The emergency heat switch works by turning off the heat pump’s primary heating system and activating the backup heating system. The backup system uses electric resistance heating to provide warm air to the home. This type of heating is more expensive and less efficient than the heat pump.
When to Use the Emergency Heat Switch
The emergency heat switch should only be used in emergency situations. It is an essential safety feature. If the heat pump’s primary heating system malfunctions, the emergency heat switch can provide a backup source of heat until the primary system is repaired or replaced. However, it is important to remember that using the emergency heat source for an extended period can significantly increase your energy bills. In this case, it is essential to have the heat pump inspected and repaired by a qualified HVAC technician as soon as possible.
