Lennox Ultra Low Emissions and NOx furnaces
SL297NV Variable-Speed, Ultra Low Emissions Gas Furnace
This year, Lennox has introduced the SL297NV Ultra Low Emissions Gas Furnace, the lowest emission furnace on the market, which produces 65 percent lower NOx emissions than standard low NOx furnaces, offering the ultimate in comfort and emissions compliance. With a heating efficiency rating of 97.5 percent AFUE (Annual Fuel Utilization Efficiency), the first-of-its-kind SL297NV can potentially save homeowners hundreds of dollars per year, compared to an older furnace. The variable-speed blower motor allows for constant and efficient adjustments of air flow speed and gently disperses even heat throughout their home. This furnace technology allows for a higher heat temperature that burns more of the NOx emissions before they are released into the air, allowing homeowners to breathe easy about the low impact heating their home is making on the environment while saving energy.
Lennox SL280NV Ultra Low NOx gas furnace
The Lennox SL280NV Ultra Low NOx furnace produces 65 percent lower NOx emissions than standard low NOx furnaces, offering the ultimate in comfort and emissions compliance. With a heating efficiency rating of 80 percent AFUE, and as part of a Lennox iComfort thermostat-enabled system, the SL280NV delivers exceptional comfort all winter long and helps homeowners save energy. Lennox’ innovative technology allows for a higher heat temperature that burns more of the NOx emissions before releasing them into the air. Additionally, a variable-speed blower motor and two-stage gas valve allows the furnace to adjust airflow and heating output to help homeowners to maintain their ideal temperature throughout their home, quietly and efficiently.
The SL280NV furnace offers industry-leading features, such as:
- Ultra smart control: When combined with the Lennox iComfortS30 ultra-smart thermostat, the Lennox SL280NV adjusts the heating for energy savings based on the homeowner’s routine, helping them save money.
- Comfort: The Lennox SL280NV variable speed blower can help condensing units control humidity levels, and also offers continuous filtration for cleaner, healthier air for homeowners.
- Environmentally friendly: The Lennox SL280NV operates at two different levels of heat output, which maintains a consistent temperature in the home using as little fuel as possible. This helps homeowners stay comfortable and reduces their utility costs, while lower emissions help with reducing air pollution.
