What does "hybrid heating" refer to in HVAC systems?

Hybrid heating refers to a system that combines two different types of heating methods to optimize energy efficiency and comfort. In the context of HVAC systems, this typically means the integration of electric heat and gas heating. The system can automatically switch between the two based on various factors such as outside temperature, energy costs, or system efficiency, allowing for a more flexible and cost-effective approach to heating.

Using both electric and gas heating can capitalize on the advantages of each type, such as the efficiency of electric heating when temperatures are milder, and the cost-effectiveness of gas heating during colder conditions. This balance can lead to lower energy bills and improve the system's overall performance.

Understanding the mechanics of hybrid heating systems is crucial for HVAC professionals, as it enables them to design and implement more efficient heating solutions for a range of residential or commercial applications.
