Biasi Boiler Guide

Hi Guys,

My Biasi Combi boiler is making banging, whistling noises. Central heating works properly, but when it comes to hot water it comes in waves hot/cold, hot/cold. Noise is being observed only when there is a demand for hot water. What is the issue?

Thanks

Oliver

Hi Oliver,

I think detail investigation is needed. You should contact GasSafe Registered technician, as it may be a pump, burner/igniter issue or even PCB. GasSafe technicial will be able to tell after 5 min what’s wrong and you end up replacing only this part which is faulty, not all the parts that may be faulty. At the end it is probably cheaper solution
