Frequently Asked Questions About the Bryant 810S
How does the Bryant 810S compare to the 800S furnace?
The 810S and 800S are nearly identical models - both offer 80% AFUE efficiency with 18-speed multi-speed PSC blowers and single-stage gas valves. The primary difference is model designation and potentially minor cabinet design variations. Both use standard B-vent metal flue venting and provide the same flexible airflow customization. Your installer can help you choose based on current availability, pricing, and any region-specific model preferences. Performance and reliability are equivalent between the 810S and 800S.
What are the benefits of the 810S's 18-speed blower for Portland homes?
Portland homes range from 1920s Craftsman bungalows to modern construction, each with unique ductwork layouts. The 810S's 18-speed blower gives your installer 18 discrete airflow settings to choose from during installation. This flexibility allows precise matching to your home's specific needs - whether you have long duct runs, multiple stories, or challenging room layouts. Once set, the blower maintains that optimized speed for consistent comfort. This is particularly valuable in older Portland homes with duct modifications from additions or remodels.
Is the 810S a good furnace for replacing an old unit in a Portland home?
Yes, the 810S is an excellent replacement option for Portland homeowners upgrading from 60-70% AFUE furnaces. The 80% efficiency provides significant gas savings (15-30% improvement) without the higher cost of 95%+ condensing models. As a non-condensing furnace, the 810S uses standard B-vent metal flue - the same type of venting your old furnace likely uses. This means simpler, less expensive installation compared to high-efficiency models requiring PVC venting. The 18-speed blower adds flexibility for optimizing airflow in your specific home layout.
