Unlike older models that allowed heated air to escape up the flue, these modern systems capture and reuse heat that would otherwise be lost. By cooling the exhaust significantly, these systems condense water vapor that would normally be wasted, reclaiming the latent heat contained within the moisture.
Advanced Combustion and Heat Exchange: Maximizing Efficiency and Condensation
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 furnaces represent a significant evolution in home heating technology, designed to minimize energy waste while maximizing comfort.
In contrast, a high efficiency furnace typically boasts an AFUE of 90% or higher, meaning that for every dollar spent on fuel, 90 cents or more is converted into usable warmth for your home. High efficiency models, however, utilize a secondary heat exchanger to extract additional thermal energy from the exhaust gases.
Advanced Combustion and Heat Exchange in High Efficiency Furnaces
High efficiency furnaces frequently incorporate variable-speed blowers that adjust their output based on the current demand. This phase change is the key to their superior efficiency, as it releases substantial heat that is transferred into the living space.
