What defines a dual fuel heating system?

A dual fuel heating system is defined by its ability to combine two different types of heating sources to maximize energy efficiency and comfort in varying weather conditions. Specifically, this system integrates a heat pump with a fossil fuel furnace, allowing it to leverage the strengths of both technologies.

In moderate temperatures, the heat pump is generally the most efficient source of heating, drawing heat from the outside air to warm the indoor environment. However, when outdoor temperatures drop significantly, the heat pump's efficiency decreases. In such cases, the fossil fuel furnace kicks in to provide additional heating power, ensuring that the space maintains a comfortable temperature without compromising efficiency.

This configuration enables homeowners to take advantage of the efficient heating capabilities of a heat pump during milder weather, while also having a reliable backup from the fossil fuel furnace in colder conditions. As a result, a dual fuel system is particularly beneficial in climates with fluctuating temperatures, providing cost-effective and reliable heating solutions year-round.
