When it comes to selecting a new furnace, the realm of high-efficiency models offers a plethora of upgraded and redesigned components that elevate them to a league of their own. With enhanced safety features, superior fuel efficiency, and a host of comfort-enhancing elements, choosing the standout feature may leave you spoilt for choice.
Safety, efficiency, and comfort are at the forefront of high-efficiency furnaces, defined as those achieving or surpassing 90 percent AFUE (annual fuel utilization efficiency). This marks a notable 12- to 30-percent improvement over mid-efficiency and older furnace models. However, the benefits of new furnaces extend far beyond enhanced fuel efficiency.
Every redesigned component synergistically enhances performance, ensuring safer operation and optimum comfort for homeowners. Let’s explore the key enhancements and features of high-efficiency furnaces:
-
Sealed combustion chamber with direct-vent intake: Enhances fuel-to-heat conversion while preventing wastage of warm household air for combustion. This feature not only safeguards against airborne household contaminants and chemicals but also prevents back-drafting.
-
Modulating gas valve: Automatically adjusts heat output to match varying heating needs, enabling precise control with minimal fuel consumption.
-
Variable-capacity blower: Delivers uniform heating throughout the home by adapting airflow to temperature requirements, significantly reducing electricity usage.
-
Secondary heat exchanger: Condenses hot exhaust gases from the primary heat exchanger, extracting latent heat and converting it into usable warmth for the home. This innovation facilitates sealed sidewall venting, ensuring practicality and safety.
Sidewall venting, sealed combustion, and direct-vent intake collectively eliminate the risk of back-drafting, further enhancing safety.
