Hot Air Furnace

In areas known for their harsh winters, a hot air furnace is a necessity! It has four basic components: the burner through which gas or oil is delivered and burned, the heat exchanger which transfers the heat from the burning gas to the air distribution system, the ductwork which functions to transfer the heated air throughout the house, and the vent pipe that carries the exhaust byproducts (such as water vapor and carbon dioxide) to the outside unit.

How a hot air furnace works is pretty simple. The air is heated in the hot air section of the furnace until it reaches a certain temperature, at which point the blower turns on. This hot air is then circulated throughout the house until the set temperature on the wall thermostat is reached.

If you are in the market to buy a hot air furnace, you are bound to run into a huge variety in terms of size and efficiency. Let’s look at a few different types of hot air furnaces.

1. Variable-Speed Hot Air Furnaces circulate more air throughout the home for a longer period of time. This helps to reduce air stratification and improve air quality by increasing air filtration. Variable-speed hot air furnaces are preferred by customers for their low operating costs and whisper quiet operation.
2. Two-Stage Hot Air Furnaces have an electric hot surface ignition and an induced combustion system which allows these hot air furnaces to operate quietly and efficiently. While they operate at low capacity during most of winter, on really bitter cold days, the second stage kicks in to maintain a comfortable indoor climate.
3. Single Stage Hot Air Furnaces offer new features that cannot be matched by the older furnaces. The inducer draws the correct quantity of combustion air into the furnace. An electronic ignition system replaces the function of the old pilot light, and the direct-drive blower sends the warm air to each room of your house.  All of these features serve to make your home comfortable and reduce your heating fuel bills.
