Hi Folks,

I have a Ferroli Combi boiler, it is pretty old, but did not cause much of a problem so far. We have realized that there is sth wrong and the boiler is loosing a pressure. I have tired to re-pressurize the system by the vessel- it was about 10 min job, and worked fine, but just for 2 weeks. Now boilers shows low pressure again. There is no leak under the boiler or from radiators, I should add. What is wrong?

Thanks

Tom

Hi Tom

I think you defied a fault correctly, just because Ferroli are low-cost boilers, parts are getting used faster than with other brands. I believe that if first you would replace an expansion vessel and then use hand pump to re-pressurise it, it would be a permanent fix
