Two-Stage
Variable-Speed
Reliable two-stage Low NOx furnace with InteliSense™ remote monitoring delivers cleaner emissions and simpler installation. Perfect for Portland homes prioritizing environmental responsibility with proven technology.
How the Bryant 821T Solves Portland Heating Challenges
Engineered for the Pacific Northwest's unique climate - from long wet winters to environmental concerns
Portland's Long Wet Winters
Portland averages 154 rainy days per year, with temperatures hovering between 35-50°F for months. The 821T's two-stage gas valve runs at 65% capacity most of the time, providing consistent warmth without the temperature swings of single-stage furnaces.
Maintains comfortable 70°F warmth even as outdoor temps fluctuate between freezing nights and 50°F afternoons.
Cleaner Air for Portland Families
The 821T's Low NOx burner reduces nitrogen oxide emissions by up to 40% compared to standard furnaces. This contributes to better air quality in the Portland Metro area, where air inversions can trap pollutants during winter months.
Environmentally responsible heating that reduces your home's contribution to Portland's air quality concerns.
Replacement for 60-70% Furnaces
Many Portland homes still have 60-70% AFUE furnaces from the 1980s-1990s. Upgrading to the 821T's 80% AFUE can save $200-400/year on heating bills while providing better comfort with two-stage operation and cleaner emissions.
Reliable heating at better efficiency than older single-stage furnaces, with proven non-condensing technology.
No Condensate Drain Required
Non-condensing design means the 821T doesn't produce acidic condensate, simplifying installation in homes without existing condensate drains. This can save $500-1,000 in installation costs compared to high-efficiency condensing models.
Simpler installation with standard metal venting - ideal for direct replacements and retrofit applications.

Frequently Asked Questions About the Bryant 821T
What is Low NOx technology on the Bryant 821T?
The 821T features a specially designed burner that reduces nitrogen oxide (NOx) emissions by up to 40% compared to standard furnaces. NOx contributes to smog and air quality issues, particularly important in Portland where winter air inversions can trap pollutants. The 821T meets California's strict SCAQMD Rule 1111 for Low NOx emissions, making it an environmentally responsible choice while maintaining reliable two-stage heating performance.
How does the 821T's two-stage operation benefit Portland homeowners?
The 821T runs at 65% capacity most of the time during Portland's mild 35-50°F winters, providing consistent heat without temperature swings. It only ramps to 100% during extreme cold snaps. This two-stage operation reduces cycling, extends equipment life, and maintains more even temperatures throughout your home - especially important in drafty older Portland homes where single-stage furnaces create hot/cold cycles.
What's the difference between the 821T and 820T models?
Both are 80% AFUE two-stage furnaces with InteliSense™ monitoring and variable-speed ECM blowers. The key difference is emissions: the 821T features a Low NOx burner that reduces nitrogen oxide emissions by up to 40% compared to the standard 820T. If you're environmentally conscious or replacing a furnace in an area with air quality concerns, the 821T offers the same comfort and reliability with significantly cleaner emissions - important for Portland's winter air quality.
