FERROLI MODENA 80 Boiler

[S394BC]

Because the boiler is fitter on timber supports in a airing cupd. the pump makes a humming noise, which can be heard in adjoining rooms, I should add there is nothing wrong with the pump, it is because it is where it is.

Would there be anything wrong if the variable speed pump was put on speed setting 2, rather than the factory setting 3 ?

I assume this could reduce/eliminate the humm ??

An advice please would be appreciated
Thanks

Combis generally need them on 3. You could always give it a try and see what happens, if it starts cutting out on overheat turn it back up.
Are you sure the pump isn't on it's way out btw? They can get noisy on these before they pack in, though they can go on like that for ages.

Thanks, but no it is not the pump, its been like it from day one.
Its because the boiler is mounted on timber and not brick, hence the humm noise.
Was wondering if anti vibration mountings could be fitted either side of the pump ?
