It is important to learn about the different types of forced air furnaces whether your home furnace is getting older, or if you’re just interested in lowering your energy bills throughout the cold season. Today, we at Steve’s Heating & Air would like to discuss the different types of furnaces.
Types of Forced Air Furnace Heating
Between furnaces and how they operate, there are a few important differences. To create as much heat as possible, some do it in a single stage where others it in two different stages and have more control over how much heat they generate. How their blowers operate is another primary difference in the furnace. Throughout your home, the blower is what moves the generated heat. This major operational difference affects comfort and efficiency during use, others run their blowers at variable speeds.
Single Phase VS 2 Stage Furnace
Single phase products are older furnaces, and this indicates they generate heat at their maximum level all the time. Because it makes the furnaces more affordable, this isn’t necessarily a bad thing. Frequently operating with an AFUE (annual fuel utilization efficiency) above 95% efficiency levels, the two stage furnaces are known for being more efficient. With levels in the 80’s for AFUE, the single-phase units on the other hand usually operate. Because of how they operate, there is a major efficiency difference between these two types of furnaces. After going through the warm-up phase and operating for longer periods of time furnaces are at their most efficient. With a single-phase furnace, it will warm your home when it comes on and shut back off again. During the coolest period of the day, a dual phase furnace comes on at maximum power to warm your home. Instead it lowers to the low heat output level and continues to run and work to keep heat levels within a single degree or two of the thermostat’s settings after your home is warm it doesn’t shut off. To keep your home at comfortable temperatures, a two-phase furnace continues to operate efficiently, and it simply cycles between the high and low heat output levels by continually running,
Standard Furnaces VS Variable Speed Furnaces
With blowers that run at the same power level all the time is how a few furnaces function, and they are standard furnaces. Depending on how much the temperature of your home needs to be increased, others operate with a blower that speeds up and slows down. Using less electricity and creating a more comfortable environment, the blower runs at a slower rate, should the house only need a small bump in warmth. As it should keep your home at comfortable levels for years longer than your basic single-speed blower ever could, this style blower is shown to have a longer operating life as well. The right amount of heat with precision and is often paired up with a two-stage furnace for peak efficiency is delivered with a variable speed blower. Being more efficient than single stage models, two stage furnace and with variable speed blowers, it takes things a step further. Though they should make up for their added cost with efficiency improvements and a more comfortable environment all throughout their operating lifespan, these more modern and efficient furnaces are slightly more expensive, making them a worthwhile investment to consider.
