We had an air source heat pump fitted back in January and though we're happy with the performance of the system, our Wilo circulation pump keeps making a loud vibrating noise that can be heard through parts of our upstairs.

This happens every few weeks, and is getting frustrating now. It's not 5 minute thing, as the noise can last for a few whole days What could be the cause? Or is it a faulty circulation pump
