Can a back boiler explode?

These boilers can explode if they are left unused and empty. Usually residual moisture left in the boiler turns to steam and as the back boiler gets heated pressure builds up and it gets extremely hot because it is empty, and then explodes.

Why are condensing boilers more efficient?

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.
