Is a whistling boiler dangerous?
Regarding this, why is my boiler making a whistling noise?
Boiler whistling noises can also be caused by kettling, or could be due to trapped air within the system. Engineers will also identify what caused air to become trapped in the boiler and perform appropriate repairs. Whistling noises may also be caused by a loss of water pressure or a blockage.
Thereof, is a whistling radiator dangerous?
A whistling noise usually indicates that water is flowing through the radiator too high. Tapping This is usually caused by an incorrectly fitted thermostatic radiator valve. The problem may be that the valves have been mistakenly switched (especially if you have just had a new radiator fitted).
While historically, boilers would over-pressurise and explode with alarming regularity, modern boilers are manufactured to be able to withstand excessive pressure, and can typically handle an operating pressure of 20 PSI. When pressures increase beyond this level, the boiler can fail, which can lead to an explosion.
