  • Boiler Efficiency | CleanBoiler.org

    The stack temperature of a 4-pass boiler will be lower than the stack temperature of a similar size 2- or 3-pass boiler operating under similar conditions. The 4-pass will have higher efficiencies and lower fuel costs. This is not an opinion. It is basic heat exchanger physics. The 4-pass design yields higher heat-transfer coefficients.Learn More

    Flame temperature and flame exposure (size and distance)from heat exchanger. You lose up to 50% of radiant transfer with a small flame. A three pass boiler should always be more efficient than a single pass but anything can be misfired to create a high AFUE. AFUE does not address delivered efficiency just tampered with burner operation.Learn More
