Boiler Making Loud Noises: Banging, Whistling & Other Noises

Loud noises like whistling could be caused by a fault with the pressure in the boiler. It may be the case that there isn't enough water flowing through the system due to low pressure - you could check the pressure gauge to see if it is below one bar. If it is, the pressure is too low, and it will need to be increased by a qualified engineer.

Boiler getting overpressurized -- reaches 30 PSI and PRV

When the boiler fires up again at night, pressure spikes to 30 PSI, the relief valve lets off some water, and then overnight as the boiler is cycling, pressure stabilizes in the range of 22-26 PSI. For what it's worth, the boiler cycles pretty quickly overnight â€" it’s on for 2 minutes or so before shutting off again.
