The knocking noise in a Vaillant VRC boiler is often caused by a phenomenon called kettling. Kettling occurs when limescale and other debris build up in the heat exchanger, causing water to boil and create steam bubbles. When these bubbles collapse, they create the knocking or banging noise. This can be caused by hard water, which contains high levels of minerals that can accumulate in the heat exchanger over time. Regular maintenance and descaling can help prevent kettling and reduce the knocking noise in the boiler. **
