Rheem Classic 90 Plus
Two Stage Gas Furnace
With Dual Comfort Control
The Rheem Classic 90 Plus Two Stage Gas Furnace With Dual Comfort Control
The Rheem Classic 90 Plus with Dual Comfort Control has two stages of heating to save energy and keep your home at its comfortable best. Most of the time, this furnace operates in its energy saving "low-heat" stage to deliver a gentle and steady flow of heating comfort. The burner flame is smaller and the blower fan operates more slowly, using less energy to save you money on your energy bill.
On the coldest days, when you need more heat, the furnace automatically switches to "high-heat" stage to deliver the maximum heating comfort.
Conventional furnaces, operate at just one stage-high-heat-and then abruptly shut off when a selected temperature is reached. So the temperature of the home constantly swings up and down- warming when the furnace runs, and cooling when it's not.
With Dual Comfort Control, the temperature of your home stays at the comfort level you select-wherever you set the thermostat. And with Rheem equipment, displaying the PrOzone label, you can enjoy comfort on the inside while protecting the environment outside.
HERE'S
HOW DUAL COMFORT CONTROL WORKS
- Two heat exchangers - a primary and a secondary - extract more heat from the burner than any less efficient furnace. So you save on energy because you get more heating output from each ounce of natural gas. Both heat exchangers are made of stainless steel and carry a limited lifetime warranty.
- The integrated, two stage control board directs activities of the gas valve and blower to efficiently keep your home at its comfortable best.
- The two stage gas valve adjusts the flow of gas to the burner providing "low heat" and "high heat" as needed for maximum efficiency.
- A permanent washable filter makes it easy to keep a clean filter in place. No more filters to buy or store. A clean filter helps your furnace run more efficiently and can improve the indoor air quality of your home.
