Why Does My Boiler Make A Banging Noise When Firing Up

Because the water is much slower to heat due to this barrier, the burners stay on longer, causing the heat exchanger to overheat. And when this happens, small pockets of water trapped between the heat exchanger and the limescale heat up to the point of steam bubbles (which burst as they escape). Water pressure/flow is too low.

If so this is where you're losing water (and hence pressure). It indicates that the expansion vessel (probably built-into the boiler) is faulty. It may just have lost pressure (there's a Schraeder(sp?) car-tyre-style valve you can use to top it up) but could have failed entirely (e.g. if water comes out of the air valve!).

The Temperature in Your Boiler and the Dangers of Overheating

If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking. When the water temperature in the boiler becomes too high, it increases the water pressure throughout the system. This will cause breaks to begin occurring at valves and connectors.
