A mixture of fuel and air burns in the furnace burner to generate heat. The heat is then conveyed to your home’s interior via ductwork or pipes. A furnace burner in your Salt Lake City home can function in one of three main ways. Here are the different furnace burners based on their operation:

Single-Stage Burners

Single-stage furnace burners only have off and on switches. These furnaces will operate at their pre-set capacity, not considering the interior conditions of your home. Though they have low installation costs, single-stage furnaces don’t have an efficient comfort level, especially in mild weather conditions.

Two-Stage Burners

These furnaces have three operating modes — high-fire, low-fire and off. High-fire is similar to a single-stage furnace working at full capacity and is suitable for cold weather. Low-fire is an in-between stage, which allows your furnace to work at a factory set level below its highest capacity. This allows it to match your home’s heating requirements and lowers your fuel costs.

Modulating Variable Speed Burners

These furnaces control the heat output and speed according to the exterior temperatures and desired level of comfort. A modulating variable speed furnace is the most energy-efficient furnace burner and will save you a substantial amount in energy bills. Though these furnaces are the most costly, they provide the most ambient interior temperatures.

There are various fuel sources you can choose for your furnace burner. Natural gas, propane, electricity, and oil are the most common options. When selecting your ideal fuel source, evaluate the typical operating costs of your burner with various fuel sources. You should also take into account any retrofitting which may be needed to prepare your home for the fuel source.
