  6. Forced-air gas - Wikipedia

    en.wikipedia.org/wiki/Forced-air_gas

    High-efficiency condensing furnaces condense the water vapor (one of the by-products of gas combustion) and extract the latent heat to pre-heat the incoming furnace airflow, using a second heat exchanger. [2] This increases the efficiency (energy delivered into the building vs. heating value of gas purchased) to over 90%.
