It’s also important to note that combustion within your heater requires 3 elements: source of ignition, fuel source, and oxygen. Oxygen is the most important part of proper and efficient combustion. When your heater is running, it requires oxygen to properly operate. If your furnace is 80% or less, it most likely has louvers on the front panels. These louvers in the door allow the furnace to pull air/oxygen into the combustion process. On a higher rated efficient furnace, there are no louvers located in the front panels, but rather a direct vent that comes into a sealed-combustion chamber. Lower furnace efficiencies have a negative impact not just on the environment but more importantly on your home. When your furnace is running it actually produces a negative pressure inside your home causing the cold winter temperatures to enter your home through every nook and cranny. Higher efficient furnaces have a direct vent that brings this needed oxygen directly into the chambers instead of through the home.
In the end, higher efficiency furnaces will certainly save you money, but it’s also a wise idea to look at the larger picture and application of your home to determine the best approach—it doesn’t always pay to purchase the better efficiency.
