What is Auxiliary Heat

Auxiliary heat, also known as emergency heat or backup heat, refers to an additional heating source that is used in certain heating systems to provide supplemental or primary heating when the primary heat source is unable to meet the heating demand. It's commonly used in heat pump systems, especially in cold weather conditions.

Heat pumps are efficient heating and cooling systems that use electricity to move heat from one place to another. During the heating season, a heat pump extracts heat from the outdoor air (even in cold weather) and transfers it indoors to warm the living space. However, as outdoor temperatures drop, the heat pump's efficiency can decrease because there's less heat available in the outdoor air to extract.

This is where auxiliary heat comes into play. When the heat pump's ability to extract sufficient heat becomes limited due to very cold temperatures or a high heating demand, an auxiliary heat source, often electric resistance heating, is activated to provide additional warmth.

Electric resistance heating works by passing an electric current through a resistant material, generating heat. While it's effective at providing heat, it's less efficient than a heat pump, as it directly converts electricity into heat without the energy transfer mechanism used by the heat pump.

Key Points About Auxiliary Heat

Activation: The thermostat in a heat pump system is usually programmed to switch to auxiliary heat when the indoor temperature falls a certain number of degrees below the set temperature.
Supplementing Heat: Auxiliary heat supplements the heat pump's efforts to maintain the desired indoor temperature when outdoor conditions are too extreme for the heat pump alone.
Energy Costs: While auxiliary heat provides warmth, it can also increase energy costs due to the less efficient use of electricity compared to the heat pump.
Emergency Heat: Some thermostats have an "emergency heat" setting, which forces the system to use only the auxiliary heat source. This is typically used when the heat pump is malfunctioning or during extreme cold spells.
Thermostat Control: Modern thermostats and control systems manage the transition between heat pump and auxiliary heat, optimizing comfort and energy efficiency.

Overall, auxiliary heat is a necessary component in heat pump systems to ensure consistent and comfortable heating even in very cold weather. It's important for homeowners to understand how their heating system operates and to use it effectively to balance comfort and energy efficiency.
