How does one calculate boiler efficiency? - Quora

The boiler efficiency is a rain of the chemical energy in the natural gas versus the amount of energy put out by the boiler. You will need to know the amount of gas fed into the boiler as well as the thermal energy imparted onto the water flowing through the boiler. Keep your units of measure to be consistent.
