Hi (my first listing!)
I have been getting a loud noise around the house, sounding like it is coming from the boiler only once everything is up to temperature. It is not permanent but does happen every single time the boiler is firing and obviously the pump is running.
The pump is a Mid 2004 constructed Grundfos 15-50
If in the middle of the noise the pump is changed from speed 2 to speed 1 then the tone of noise changes with it, but sounds most noisy at the boiler and other pipework downstairs.
Is the noise still the pump??
Halstead Hero 60 boiler in a traditional heating system. New at start of 2005 and just serviced all ok.
Any thoughts or advice very gladly welcomed.
Thank you.
