How Auxiliary Heat Works

When the primary heating source, such as a heat pump, is unable to adequately warm your home, auxiliary heat comes to the rescue. But how does it work? Auxiliary heat is designed to provide an additional boost of warmth, working in conjunction with the primary heat source to maintain a consistent temperature.

Typically, auxiliary heat consists of electric heating elements or a gas furnace. When the primary heat source is unable to meet the heating demands, the auxiliary heat system kicks in. Electric heating elements, often located in the air handler, generate heat when electricity passes through them. On the other hand, a gas furnace uses natural gas or propane to produce heat.

Auxiliary heat systems are controlled by a thermostat that monitors the indoor temperature. When the thermostat detects that the primary heat source is not sufficient, it signals the auxiliary heat system to activate. The additional heat generated by the auxiliary system is then distributed throughout your home via the HVAC system’s ductwork.

While auxiliary heat provides that extra warmth you need, it’s important to note that it consumes more energy than the primary heat source. This is why it’s crucial to understand when and how auxiliary heat is used to optimize its efficiency and minimize energy consumption.
