sorry to hear about the problems Helen has had , some time ago we installed a feroli boiler for a customer that never did work it was in her house for 2 weeks , which required 3 in-warranty visits from the manufacturer ,I made numerous phone calls to them and it still didnt work, in the end we took it out and installed another make of boiler at our own expense!we wont use Ferroli again.Incidentally I recently came across what might be ?? or could be a potentialy a problem ? see my comments on Biasi .

THIS COMPANY IS TOTALLY RUBISH DO NOT BUY FROM THEM GO TO WORCESTER BOSCH We have a holiday cottage and have had to not take booking because there is no heating, then next week no hot water.The service engineers order spare but there is no stock so they cannot repair. Currently on hold to their service centre first time cut off after 15 minutes now 12 minutes waiting and 4th in the cue

if you are reading this and considering a new boiler DO NOT BUY FERROLI! my boiler has had 3 break downs in 15 months and altogether we have spent nearly 1 month with no hot water or heating and this was through winter,even when i explained my wife was 8 months pregnant i was told they do not work on a priority system! this company does not care after they have your money! you can't even get anyone else to fix your boiler or it invalidates your 5 year warranty. as soon as we have enough money i am ripping the ferroli out and will buy a more reliable make!

Boiler only two weeks old. Do not believe the warranty rubbish that comes with the boiler. The calls take an average of 45 mins'. They are not open 24/7 365days. I have no heating or hot water. They are not bothered and then inform me that it will be 10 days for an engineer to come and look at the boiler. I told them that the fault was the control board (melted case and smells). Was informed that the repair could NOT be done by anyone else even if I bought the part (£124.23). They have your money and do not give a s--t. 14 days over christmas and new year without heating or hot water is no joke but they are one BIG joke. Do not buy!!

never ever buy a ferroli boiler, we had ours fitted 2 months ago, and it has broken down three times!! It broke down the first week it was installed. The customer help line keeps you on the line for anything up to an hour and then you get put through to another number where yet again you have to wait in a line of up to 20 callers before you - just to ask for someone to come and repair it!!

My Optimax HE31C broke down 11 months after fitting and I had no heating or hot water.It took an age to get through to their service department (20 calls ahead of me) and I was told that the earliest time to get an engineer to call was in 10 days time. Ferroli literature says they expect to have an engineer with you within 72 hours.On the ninth day they phoned me to say it would be a further 4 days before an engineer could call.When he did call he failed to fix it and did not return for a further 3 days when it was finally fixed. I was without heating or hot water for 2 weeks in the middle of winter.I wrote to the service manager to ask for compensation and received an acknowledgement letter saying the matter would be investigated and he would respond as soon as possible. It is now 3 months later and I have not had a response despite several phone calls, an e-mail and a further letter to them. During my last phone call I demanded to speak to the Service Manager and was told that the only way to contact him was by letter. I said I had sent 2 letters and an e-mail and was told there was nothing else they could do. Ferroli after sales service is abysmal and I would never recommend their products to anyone.

I can only echo what all the other reviewers have said. Don't buy one. Don't be fooled by the 5 year warranty. Ferroli don't honour it. Ours has broken down 4 times in the first year. They came out to repair it the first time. The second time, they said a part was needed, but if they lubricated the divert valve it should be ok for a while. It was ok - for a month. Since then, despite numerous calls/promises etc... They still haven't come back I have to manually pull a plunger on it to get it to switch from water to heating. Farcical. Their call centre in a premium number - and you have to wait 30-40 mins to get through, so the "5 year warranty" costs you an arm and a leg. Still not fixed. Still waiting. And only 9 months old... Next stop is to sue them under trade descriptions act I guess...

I'm horrified to find these people at Feroli are able to stay in business, it can't last. Absolutely appauling customer service, and their boilers are so unreliable I would not know where to start. I have had this boiler for over 2 years now, and guess what? They will not honour their 5 year warranty. I have tried everything and they wriggle out of it. If anyone reads this and is even remotely condsidering a Feroli - DO NOT! Problem after problem after problem.. too many to list. I am now considering doing away with it and getting another brand I begrudge filling their pockets on the parts I keep haveing to buy to keep my hot water or heating on. I am furious I can't do anything about it.

Having purchased a ferroli Optimax HE 31C 2YRS AGO I have had nothing but problems.Heat exchanger,sensors and the printed circuit board all being changed under 5 yr warranty.The service engineer said that there was a vault with a large batch of printed circuit boards.I said well why did you not change that in the first instance,no reply.I am at present waiting for a service engineer to come and fix water leak.Takes forever to get through to service department,the boilers and after sales are utter RUBBISH.They now charge £150 for a annual service,nearly double to what they charged last year.In total I have lost the use of this boiler for over 11wks do to breakdowns and waiting for parts.DO NOT BUY A FERROLLI BOILER,NEVER you will end up paying out a fortune in phone calls a end up with high blood pressure.How the boiler got 4 stars I am totally amazed,ferroli must have posted review.

DON'T BUY THIS BOILER. I only wish I had found this site 18 months ago so I could have posted my experience. To cut a long story short it mirrors the appalling after sales service and appalling reliability detailed above. Who is rating this thing? It is only fit for the bin. I am considering taking them to the small claims court because of inaccurate claims and inaccurate advertising and the cost to me in money and time.

We are considering having our hopeless Ferroli optimax removed after only a few months. This is the second Ferroli in only two years. The first one was a disaster from Day One, firstly making a loud wailing noise every time it was switched on- a "design fault" the engineer said- and then notching up various other problems before springing a leak. Ferroli replaced this first boiler but only after the Engineer told us it wasn't really their policy to replace. This made me feel like we should be grateful for the favour! The second boiler has started leaking again and I confidently expect that Ferroli will try to refuse a replacement and will, as always, claim it is the fault of the plumber who installed it. I will probably end up cutting my losses and going for a more reliable make if only for peace of mind. Ironically our previous Glo-Worm which British gas kept telling us was only fit for scrap never gave us any problems in over 20 years - says a lot for modern manufacturing!

wow I am shocked to read to review above - is this the same boiler!. My boiler is less than 18 months old and has had 2 breakdowns requiring new parts each time. The first issue when less than a year old a new circuit board required -2 weeks wait with no hot water or heating (incovenient but in the summer). The second time 4th February this year and 14 WEEKS LATER STILL NOT FIXED. The insurance company cannot get the part even though there are several ferroli spares sites and on ferrolis website most parts next day delivery or fully stocked UK warehouse - this is clearly not with our part?! Sorry in the 14 weeks 2 attempts to get parts have been made first the parts were rejected by ferroli as they were faulty and yesterday the second time when the part arrived it was the wrong voltage!? I wrote to Ferroli 6 weeks ago and I haven't even received a standard letter. Now it looks like my only option will be to buy a new boiler at my cost. Please do not make the same mistake as I did.
