Question about Heating & Cooling
That clicking and knocking noise you hear is called cavitation. It's when the bubbles of steam are cooled down rapidly and implode upon themselves. Cavitation is not a good thing to have in a boiler as it can cause dramas. This cavitation is more than likely because the boiler is firing too hot. A service technician should be called to turn the regulator down a little bit.
