Why Our High Efficiency Condensing Boiler is inefficient?

The condensing the part of the water is from the gas fume. There's a lot of moisture in the flue gas. On a regular old-style boiler they just let the heat exhaust through the stack or chimney and the exhaust flue temperature can be as high as 150 ° C to 200 ° C or even more depending on the size of the boiler. In condensing boilers you're keeping the heat in the boiler longer.
