I'm a landlord. I had 2 Ferroli boilers fitted before I knew of their reputation for being at the budget end. They are the only ones that break down and if I knew on the first breakdown how much I would spend on them I would have scrapped them even though they were only a few years old. Buy cheap, buy twice. Never again.

Dreadful boiler. It was installed seven years ago and has broken down every winter, each time the PCB. Ferroli don't appear to keep any spares stock and I had to wait between 4 and 6 weeks in freezing conditions each time to get the part replaced. This forst six PCB's were free under the 5 year warranty, the next one cost over £200 plus £100 to the plumber who diagnosed (!) the fault and fitted the part. Never again!! I'd give it a score of zero if I could. Buy a Worcester Bosch.

ferroli optimax 31 c

pressure constantly dropping below 1 bar and cutting out. Constantly refilling the system but the radiators dont need bled. Told it could be expension vessel but no help in the makers book to tell me how to repressurise the vessel. really quite unhappy as I think it will cost me a fortune to get a specialist in. I have it serviced but because I was a couple of days out on the annual service I have lost the 5 year warranty facility. What can I do
