Why is there condensation inside the case of a condensing boiler?
.Inside the boiler insulated case not the heat exchanger.

The “condensing” boiler refers to what happens to the exhaust. Air is drawn into a boiler burner for the combustion process. Within that air is water (aka moisture). In a condensing boiler, in making the process more efficient, as much of the energy from the fuel is extracted as possible. Some of that energy is also the energy that the moisture (water) has that keeps it suspended as a gas within the air/atmospere. This is called the “Latent Heat of Vaporization”, also know as the amount of energy needed to convert liquid water to a gas/steam, or the amount of energy given off to convert steam to water. The amount numerically is 970 Btu/lb of water.
This type of boiler is more efficient that a standard boiler in that not as much energy goes up the stack. More is extracted and used in the heating process.
