The Rheem Prestige SeriesTM Super Quiet 80TM Gas Furnace has two stages of
heating to save energy and keep your home at its comfortable best. Most furnaces
are either “off” or “on at 100%” capacity, no matter what your heating comfort needs
may be. The Rheem Prestige SeriesTM Super Quiet 80TM, however, operates at 70% and
100% capacity.
Most of the time, this furnace operates in its energy-saving “low-heat” stage to
deliver a gentle and steady flow of heating comfort. On the coldest days, when you
need more heat, the furnace automatically switches to the “high-heat” stage to deliver
the maximum heating comfort.
The temperature of your home stays at the comfort level you select – wherever you
set the thermostat.
