This percentage rating indicates how effectively a furnace converts fuel into heat over the course of a year. As the hot gases pass through the second exchanger, they cool below the dew point, causing the water vapor to condense into liquid.
High Efficiency Furnace Air Quality and the Condensation Process
Sealed combustion is a standard feature, where the unit draws oxygen directly from the outdoors rather than from the indoor air you are heating. High efficiency models, however, utilize a secondary heat exchanger to extract additional thermal energy from the exhaust gases.
Furthermore, the implementation of PVC piping for venting replaces traditional metal flues. The Condensation Process The transition to a secondary heat exchanger necessitates a change in the physical state of the exhaust byproduct.
How High Efficiency Furnaces Improve Indoor Air Quality
This PVC system is sealed, preventing backdrafts and ensuring that harmful gases are expelled efficiently without relying on the natural buoyancy of hot air. This results in a consistently comfortable environment without the noisy blasts associated with older systems.
