Sealed combustion is a standard feature, where the unit draws oxygen directly from the outdoors rather than from the indoor air you are heating. Moreover, the sophisticated controls and cleaner burning process contribute to a longer system lifespan and improved indoor air quality.
Understanding Ventilation Requirements for High Efficiency Furnaces
Consequently, the exhaust that is vented outside is much cooler than that of a conventional furnace, often appearing as a white vapor. By cooling the exhaust significantly, these systems condense water vapor that would normally be wasted, reclaiming the latent heat contained within the moisture.
This PVC system is sealed, preventing backdrafts and ensuring that harmful gases are expelled efficiently without relying on the natural buoyancy of hot air. Rather than operating at full capacity constantly, these motors run at lower speeds during mild weather, consuming less electricity and reducing temperature fluctuations.
Understanding Sealed Combustion and Venting Requirements
This results in a consistently comfortable environment without the noisy blasts associated with older systems. This process of heat recovery is the fundamental principle that allows them to achieve efficiency ratings exceeding 90%.
