What are the Differences in Furnaces?

There are many different types of furnaces and understanding the differences can help you to determine the ideal type to purchase for your home. Furnaces will have different efficiencies, which ultimately relates to the way that the furnace is vented. One of the major differences between furnaces is whether the furnace is single stage or two stage. This will impact the way that the furnace operates and how it will ultimately heat your home.

Single Stage Furnace

The different stages depend primarily on the gas valve of the furnace. With a single stage furnace, the furnace is either on or off. This means that it will either be working at full capacity or not at all. This is often comparable to a stop and go type of system. With these types of furnaces, the system will not adjust accordingly depending on the amount of heating that is needed. It will be on until the building reaches the desired temperature and then the furnace will turn off.

Two Stage Furnace

A two stage furnace ultimately has multiple speeds, unlike a single stage furnace. These furnaces will have a different speed for mild day temperatures and a different speed for extremely cold days that require more power. These furnaces also come with the option to implement variable speed. These speeds adjust according to the power needed to efficiently heat the building, which often results in substantial energy savings. It is important to keep in mind that variable speed furnaces may come with rebates that can translate into even more savings.
