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 warmth from the burning gas to the air distribution system, the ductwork which functions to transfer the hot air throughout the house, and the vent pipe that carries the exhaust byproducts (such as water vapor and carbon dioxide) to the outside unit.

The way it works is pretty simple. The air is warmed 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:

1. Variable-Speed Hot Air models 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. These are preferred by customers for their low operating costs and whisper quiet operation.
2. Two-Stage Hot Air models have an electric hot surface ignition and an induced combustion system which allows these 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 models offer new features that cannot be matched by the older products. The inducer draws the correct quantity of combustion air in. 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  fuel bills.
