Hi, hoping one of you guys could help me with some info about the Heatline Vizo 24. It makes a really loud groaning noise mainly when the hot tap is run, it does also make the noise when the boiler fires up on central heating but not for long. I've changed the fan and pump but no joy. It does sound like it's coming from the top end of the boiler around the fan area / main heater exchanger. Could it be anything to do with the condenser unit? Any help would be much apprieated.
