  • Condensing Boilers – What Are They & Why Are They So

    Nov 30, 2016 · Conventional boilers lose latent heat and flue gas heat up the chimney, making them only about 80% efficient. Condensing boilers capture that heat by cooling the escaping water vapor below its dew point, leading to efficiency of around 95%. They can also modulate, putting out less heat during the warmer temperatures in the spring and fall, and Learn More
