How Do High-Efficiency Furnaces Attain Their Efficiency Levels?
The more efficient your gas furnace is, the lower your energy bills will be. Heating your home makes up a large part of your winter energy bills. There are a few ways high-efficiency furnaces attain higher efficiency levels than conventional ones.
A conventional gas furnace is either working at full power or is turned off. High-efficiency furnaces feature two-stage heating. They work at a lower stage of heating whenever it’s not that cold outside. This stage consumes less energy, so you save money on your energy bills.
When needed, a high-efficiency furnace will turn on its higher stage of heating. This stage can quickly heat your home to your desired temperature, even when it’s bitterly cold outside.
Second Heat Exchanger
Most gas furnaces have a single heat exchanger. A high-efficiency furnace has two heat exchangers. These furnaces are called “condensing furnaces,” as the second heat exchanger extracts heat from gasses produced by the first heat exchanger. This allows them to do more with the same amount of fuel. Leftover gas is then vented from your house.

Variable Speed Motor
A high-efficiency furnace has a motor that can operate at different capacities depending on need. A fast speed is used when called for, while slower speeds conserve energy.
Conventional furnaces draw air from inside your home and heat it. A high-efficiency furnace draws air in from the outdoors. This not only conserves energy, but it also makes the furnace safer since it’s entirely closed off from the rest of your house. There’s far less likelihood dangerous gasses will enter your home’s air.
