A two-stage heating system offers two levels of heat production: low-level heating and full-level heating. The purpose of a two-stage heating system is to avoid the constant turning on and off of a one-stage system by maintaining a more consistent, lower level of heating. A two-stage heating system can cost more to install than a one-stage heating system, but it requires less fuel to operate.
The low setting on a two-stage heating system is generally sufficient to heat your house 80 percent of the time. When operating on the low setting, you can achieve more consistent temperatures in your home since your heating system isn’t constantly cycling on and off. Additionally, since the system mostly operates on the low setting, it burns less fuel to operate.
A two-stage heating system also creates less noise when it runs. You’re probably familiar with the loud air blast your furnace creates when it cycles on, and the continuous noise it makes while operating at full capacity until it reaches a set temperature. This doesn’t happen with a two-stage heating system because it doesn’t operate at full capacity every time it runs, and it also doesn’t cycle on and off frequently.
Additionally, a two-stage heating system can improve your indoor air quality. This is because the system’s air filters can operate more effectively at a low-speed fan operation.
