Modern day furnaces have a number of features that make them more efficient, safe and powerful than older systems. Many of these features have become standard components of every new furnace, and they now play an integral part in the heating process. One such feature is a draft inducer. Today we’re going to talk about what a furnace draft inducer is, how it works and how it improves the performance of your heating system!
A draft inducer is a fan that’s located in the compartment that houses your furnace’s burners. This is not to be confused with your furnace’s air handler, which is the fan that delivers warm air to your home via the ductwork. The draft inducer is designed specifically to ensure that combustion gases are properly vented out of your furnace and that heat is distributed evenly throughout the walls of your heat exchanger.
How does a draft inducer work?
When your furnace begins a heating cycle, the draft inducer is one of the first components to start up. The draft inducer fan will spin for 30-60 seconds before the burners are actually ignited. This serves two purposes. First, it pushes out any combustion gases that were still inside of the combustion chamber after the previous heating cycle. Those gases are directed into your furnace’s flue pipe and out of your home. Second, it ensures that combustion gases are distributed evenly inside of your heat exchanger, which maximizes the heat exchanger’s effectiveness.
