Looks like I'm going against the flow here (no pun intended), but when I moved in I had a Ferroli Modena 80 E installed and apart from needing a new digital display thingy, it's worked fine, no problems, for several years now. They have excellent online documentation downloadable for their boilers too. My advice is to print out the docs for your boiler, then get a good plumber to fix/service it. Works for me!
