Recently went to a trade evening,had a look at the new modena, fairly impressed. Ferroli seemingly have got a new Research & developement team on the modena & have used feed back from their engineers to hopefully improve the brand.
From my point of view being an independant service & repair engineer, they have simplyfied it, by using a double pass main heat exh, 28mm heating & 12mm dhw instead of using a plate w/w heat exch, operated by a flow switch. The cond trap seeems easy enough to clean & access generally easy, ntc's are dry clip on [honeywell?]. It has a main pcb & also 1 on the fan [which can be replaced independently]. My only reservation is that the fan is fitted directly onto the burner manifold, rather than below & connected wiith an air/gas tube [heat?].
Time will tell whether they have improved [ & they needed too], this could be a fairly decent budget boiler with a 5 year warranty.
Hopefully they'll back it up with good engineer support.
