High Efficiency Steam Boiler? Heating Help: The Wall . In order to do this, they obviously need to get the gasses below the boiling point. If you think about it, a steam boiler operates above the boiling point, so it's not possible to run it as a condensing unit. This limits the combustion efficiency to about 86%.

Boiler systems: Economics and efficiencies

The first cost of condensing boilers is higher than that of the traditional noncondensing boilers. Therefore, the challenge the designer faces is to ensure that return water temperature to the boiler stays below 130 F; otherwise, boiler efficiency drops and the condensing boiler operates in noncondensing mode.
