If they do not have this water pressure, the water can boil before it leaves the heat exchanger (PV=NRT) ...
Wrong law.
If water in the heater boils it is saturated vapor, it does not follow the ideal gas law. For calculations of the phenomenon you described you must use the steam tables.
The noise you mentioned is from vapor bubbles collapsing as they come into contact with cooler liquid.
