2 Strange Noises
If your boiler is making strange noises such as banging, gurgling, or whistling, it could be a sign of trapped air in the system, low water pressure, or a faulty pump To release trapped air in the system, you can bleed the radiators by using a radiator key to open the bleed valve slightly until you hear a hissing sound Once the air is released, close the valve and check if the noise has stopped.
