High Efficiency Condensing Boilers: The Benefits. Modern boilers are more efficient because they are condensing boilers. A condensing boiler has a much larger heat exchanger. The heat exchanger is designed to extract over 90% of the wasted heat from the fuel it burns which would normally be lost to the atmosphere through the flue, and recycles
