How do you measure the efficiency of a boiler?

The main reason why condensing boilers are better than non-condensing models is that they are at least 25% more efficient. Their level of efficiency is achieved by using waste heat in flue gas to preheat the cold water entering the boiler, capturing more heat from the outside rather than the inside of a room.
