Ariston UKAnmeldelser 

Please find below a summary of my concerns:

Lack of Communication
Repeated attempts to contact your company by telephone were unsuccessful, as calls were not answered. This lack of communication caused unnecessary difficulty and delay in resolving an urgent matter.

Customer Interests vs. Company Policies
At every stage, it appeared that company policies and warranty conditions were prioritised over reasonable customer care, leaving the customer unsupported.

Incorrect Installation
Despite a clear request—confirmed and assured—to install a metal and copper boiler, a plastic boiler was installed instead. This represents a failure to deliver what was agreed.

Unprofessional Conduct
The attending engineer was not approachable and demonstrated a tone and manner that was inappropriate and unprofessional. This is unacceptable, particularly when dealing with customers experiencing difficulties.

Warranty Concerns
Attempts to identify grounds to void the warranty, rather than resolve the underlying issues, are deeply concerning. Such conduct is unprofessional, unethical, and significantly undermines trust in your business.

Lack of Compassion and Customer Care
Responses from Ariston focused solely on justification and policy explanation, with no acknowledgement of the stress, inconvenience, or impact this situation has caused.

Failure to Meet Industry Standards
Compared with accepted standards across other businesses in the sector, the handling of this matter falls well short of reasonable customer support expectations.

Poor Contractor Coordination
There appears to be a clear lack of communication between Ariston and Meraboiler, the installation company, resulting in confusion, accountability issues, and further inconvenience to the customer.

Customer Distress
The cumulative effect of these issues has caused significant stress and anxiety, which could and should have been avoided with appropriate customer handling.

Lack of Confidence in Product Longevity
Due to the issues outlined above, I have no assurance or confidence that the boiler will perform reliably or have a reasonable service life.

Requested Resolution
I ask that Ariston formally:

Acknowledge these failings in writing
Clarify the status of the warranty in full
Address the incorrect installation
Review the conduct and customer service training of relevant staff and engineers
Provide a clear and fair resolution to this matter

Should this complaint not be resolved satisfactorily, I reserve the right to escalate the matter further, including referral to relevant regulatory bodies or pursuing formal remedies available to me.
I expect a written response within a reasonable timeframe.
Yours faithfully,

PCB failed only 2 years old very poor that this isn’t covered.

I bought an Ariston Andris Lux Undersink Water Heater as part off a major house renovation project. The unit was fitted by a local specialist kitchen and bathroom refurbishment company in October 2025. After installation and well within the first year of purchase we noticed that there was black debris in the hot water every time we ran the tap. We hoped it would eventually flush out, but it didn’t. Communication with Ariston technical support team seemed to suggest is was an anode problem and not unknown to the company.
I applied for a replacement unit and also suggested that Ariston could send an engineer to review the problem. It seems that warranty claims are handled by their Italian company and they have been singularly unhelpful. They have left me with the opinion that they are incentivised to make warranty claims is difficult as possible. They have finally found a “reason” to reject my claim yet again, with an argument that the unit was not installed to their instruction; something which in my opinion as a retired Chartered Engineer has nothing to do with the black debris problem. All correspondence emails from their team were aggressively headed “Proposal Rejected”.
Fortunately my UK retailer agreed to let me return the unit but I still have to find an alternative and pay a plumber to fit it. Dealing with this company was incredibly stressful for an 80+ old pensioner and I shall NEVER buy anything from this company again.

Very disappointing experience with Ariston.

The Ariston water heating system was bought and installed by my plumber, not directly by me. After only four months, it stopped working.

When I tried to use the warranty, I was told it was not covered because the plumber’s installation method was not the official Ariston-approved method, even if the problem had nothing to do with the installation. The product failed after a very short time, and I was left with no practical solution.

I also tried to find Ariston technicians in Florence out of the warranty, but there were only 3 options, and the few I found had terrible reviews. The technicians I contacted would not take the job because it was too far.

In the end, I had to buy a new water heating system, pay again for installation, and dispose of the original Ariston product without ever being told what the actual fault was. I suspect it was a very simple thing to repain, because it wasnt loosing water and the lights worked perfectly, maybe a simple electric problem easy to solve.

I would not buy from Ariston ever again. The after-sales support and warranty process were very poor in my experience.

I purchased an Ariston One boiler which was professionally installed, including a full system flush. Within the first 6 months the boiler began to fail, and over the past 5 years it has broken down around 10 times.

Various parts have been replaced over time, yet the boiler continues to be unreliable and, in my view, not fit for purpose. On average, we experience two breakdowns every winter—typically during the coldest periods—leaving us without heating for up to two weeks at a time. It often takes around 4 days just to get an engineer out, and repairs are frequently delayed further due to parts availability.

Customer service has been extremely disappointing. I raised complaints in 2024, 2025, and again in 2026, where we have already experienced two breakdowns this year alone.

To make matters worse, Ariston has now suspended the warranty due to not providing an invoice or receipt for the original power flush. This is despite the system having been flushed by a qualified installer at the time of installation, and again more recently. At no point was I clearly informed that documentation would be required to maintain the warranty.

While the boiler may be designed in Italy, it appears to rely on lower-cost global manufacturing and components, which raises serious concerns about long-term reliability based on my experience.

For context, my previous Worcester Bosch Greenstar boiler ran reliably for 20 years without these kinds of issues. I deeply regret switching.

My most recent interaction with Ariston customer service was particularly poor—dismissive and unhelpful, with little interest in resolving the situation.

I would strongly advise others to carefully consider their options before choosing this boiler, especially if reliability and aftercare are important to you. If you want no heating in winter for an average of two weeks, this is the boiler for you, I was told they will never replace the faulty boiler they will just keep replacing parts until the warranty runs out.

Prompt service friendly professional staff.

Great engineer very competent

Never again would get ariston boiler or get wm donnelly who they work with to do any work in my house

In France bought a heat pump boiler which costs 1800 euros. The electronic card failed after 9 months. Ariston refused to even replace the part as they say the installer didn't fit the required anti-corrosion dielectric on the hot water outlet. Maybe he didn't but that is nothing to do with the card failure. The company is dishonest and these products are low quality junk. Most of the advertised functionality never worked anyway such as the timer for switching on. So I take a big hit and junk this new kit.

Customer after care is not good. We were missing parts and tried asking a question. They replied asking for serial number. I sent photos of it. I also sent pictures of products. Heard nothing, I had to order these separately. Not really clear when buying the product. Wouldn’t recommend.

Hi, your engineer he doesn’t really good job. He’s very friendly. I am really appreciate for his service hidden accident. Thanks for your service.

Any excuse not to continue our warranty, boiler is only 4 years old, would never purchase again, awful boiler and awful company to deal with!!! Avoid!

Dealt with my enquiry/problem efficiently. It was hard to get over that it was not the thermostat, but the clock within the boiler, probably because despite my boiler not being old, new ones no longer have that system, so the person I dealt with was probably not aware of such a boiler. Despite that the problem was resolved with the help of their approved Heating Engineering firm. The person I spoke to was very helpful and pleasant.

Very nice engineer when he phoned and let me know he was on his way, he was fixing a boiler that is in one of my rental properties so I was not there and the tenant has not contacted me ! So no need is good news.. well done..

5 (all day appointments)visits to fix a problem that took 90 mins to repair, plus 1 day they didn't show up at all. We had to get through to management on the phone as this was getting ridiculous. All the while a 91 year old had a leaking boiler to deal with.
Whats their slogan, Ariston goes on and on and on..... they're not kidding
I'd never use them again

Knowledgeable polite young man. Even was happy to answer a question on his day off.

Excellent monitoring and information service backed up by annual service of heating system of similar quality from Status Heating.

Contacted Ariston regarding an issue with a newly installed boiler. They were very good in coming back to me promptly and arranging for a service partner to contact me for an inspection. Many thanks to Roberto and Gabriela for their prompt response and efficient reporting of this issue.

Brilliant service and warranty period
