Tech3TM Series Performance. Strictly Top-Of-The-Line.
Tappan's Tech3 Series 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.
Likewise, they'll pay back dividends providing energy savings
worth hundreds of dollars per year along with reduced maintenance
costs.
Two-Stage Technology That Quietly Up-Stages
The Rest.
On mild days, which statistically average about 80% of the
heating season, a furnace that idles down to a reduced-heating
capacity improves comfort.
Tappan'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.
