NuTone's ultra-efficient, two-stage, variable-speed furnaces are up-to-speed with the expectations of today's comfort-minded and energy-conscious consumer. Providing the latest two-stage, variable-speed technology, it stands to reason that these furnaces will cost more up front. But over the lifetime of your initial investment, they'll provide unparalleled comfort, the quietest operation, and significant improvements in indoor air quality. This NuTone furnace is one of the most efficient gas furnaces available today.
Likewise, they'll pay back dividends providing energy savings worth hundreds of dollars per year along with reduced maintenance costs. This furnace is an iQ Drive® Ready Furnace and is designed to seamlessly integrate our Award-Winning iQ Drive® Air Conditioner, to create the most energy efficient comfort system available for the home.
Awarded by the U.S. Department of Energy and the Environmental Protection Agency for helping to conserve energy, promote cleaner air, and prevent global warming. To qualify, furnaces must have an Annualized Fuel Utilization Efficiency (AFUE) rating of 90% or higher.
On mild days, which statistically average about 80% of the heating season, a furnace that idles down to a reduced-heating capacity improves comfort.
NuTone's innovative two-stage furnaces with blowers powered by variable-speed motors, are built with this purpose in mind. In the first stage, or low-fire mode, these furnaces use approximately 68% of their total heating capacity running more slowly, quietly and efficiently. Then, during colder extremes--when maximum output is finally needed--a second stage boosts fuel flow while the blower ramps up variably to maximum speed. Ramping gradually through heating cycles increases quiet performance.
Since air is circulated at longer cycles more continuously, room temperatures are balanced and more comfortably mixed. Temperature swings are reduced to barely a couple of degrees and hot and cold spots are minimized.
Comfort is nice, but saving money on monthly heating costs is even better. An economical two-stage furnace can also reduce your energy bills by hundreds of dollars each season when compared to older, inefficient furnaces. So when utility bills come due, you can breathe a lot easier.
