We have just had a new EVO Combi boiler fitted with new rads. When we turn on the hot water there is a loud clonk from the boiler, this also happens when the central heating is switched on and we turn on the hot tap. As this is the first time we have had a combi boiler is this normal as it it rather loud and our old Main system was really quiet?
