Variable-Speed, Ultra-Low Emission Gas Furnace
60 AFUE VS 80 AFUE
A step up from single-stage furnaces because its gas valve offers an additional lower setting. Most of the time the unit will meet heating needs at its lower stage, resulting in balanced and consistent temperatures with lower energy use. Should the low heat setting not heat the space quickly enough, the furnace will switch to the high setting. This ability to switch between the two settings offers greater comfort and efficiency.
The standard 80% AFUE means the SL280NV can reduce your heating costs, compared to an older furnace.
Equipped with the most efficient variable-speed blower motor available with the ability to slowly ramp the airflow up or down to provide consistently even temperatures as it only produces the necessary amount of airflow at any given time. Plus, variable-speed motors can run at a continuous low speed which allows for better air filtration and humidity removal.
Built for durability and reliability, the SL280NV is made with a heavy-duty steel cabinet for a long, trouble-free life.
