“Worst boiler on the market”

Written on: 03/04/2022 by Kirsten108 (1 review written)

Do not waste your money on these boilers. Absolutely rubbish. Our boiler is only three years old and we are replacing it already. Buy cheap buy twice. Would give minus stars if I could… Read Full Review

“Ariston Boiler in a static lodge”

Written on: 22/11/2021 by DougJones (1 review written)

We purchased a new static lodge 3 years ago that came with a Ariston combi boiler. We get a fume smell when ever we use the boiler. We have had all service done by Ariston each year. We now have a fault with the fan when the boiler is turned off with the hot water or heating the fan would continue to run for ever or until I turned off the mains electric. We rang Ariston who have now SACKED ALL THEIR OWN ENGINEERS! now taken on a company called Status. The chap came and to be honest don,t think… Read Full Review

“Smell in house makes me feel sick ”

Written on: 16/03/2019 by AnyUserButNotMe (1 review written)

Had an Ariston combi boiler installed three months ago and from day one it smells. I can smell it in every room of the house, told installer who didn’t seem to find a problem but after paying nearly £3000 I am seriously considering getting another installer fitting a Bosch Worcester like the one we used to have. My nose feels stuffy and blocked all the time. My husband says it smells like cats wee but I think it’s like an old oily engine with a sulphur smell. It’s just not right and it… Read Full Review

“BEST BOILERS EVER!!”

Written on: 23/10/2018 by dazshone (1 review written)

We fit these and they are very cost effective and very reliable boilers, most people who bring this products name to shame are customers who have had a poor install. Most of the breakdowns on these boilers is caused by poor installation and poor water quality in the system that will cause any boiler to fail. I recommend these boilers but please make sure your systems are flushed and filters are fitted and correct inhibitor concrete are used. 10/10… Read Full Review

Written on: 01/03/2017 by Christiant33 (1 review written)

Loved my CLAS HE Evo boiler. had one issue with the boiler, however Ariston came out the next day to repair the boiler, the engineer even had the parts on his van. This boiler was great value for money and even came with a 12 year warranty… Read Full Review

“Great Boiler 12 yr warranty ”

Written on: 23/06/2016 by LukasGilbert310 (1 review written)

I finally replaced my old Vokera boiler and was persuaded to install the Ariston CLAS HE 30kw. We have not had one issue with the boiler and it also came with a free 12 year manufacturers warranty. The value for money compared to the Worcester Bosch alternative was also a huge reason for opting to install the Ariston. The installer told me that the Ariston range has much improved and is the equivalent to a Valliant EcoTec. Our property seems to heat a lot quicker and we never run out of hot… Read Full Review

Graeme1952's Comment

Written on: 24/06/2016

Totally agree with this review, my plumber has fitted 3 boilers over the last 25 years for me and the Ariston 38 is the latest one fitted 3 months ago. I am a retired commercial heating engineer and can't fault the boiler, I also have the remote control SENSYRS fitted which tells Ariston if there's a problem with the boiler and because my plumber has done their training he is the one who would come out to fix it. I had a Worcester 38Cdi previously and after my first quarterly gas bill I've saved £122 compared to last year with no change to how good my heating or hot water is. I am a happy bunny.

“A honey trap”

Written on: 07/10/2015 by luScott226 (1 review written)

I was lured into buying a CLAS HE 30 boiler five years ago by the fact that it came with a five year warranty. However five years goes surprisingly quickly and although during that time only one repair was necessary, there was a continual issue with the time clock which had to be replaced four times. Now that the boiler is out of guarantee and needs repairing again, the only option Ariston will give you is a fixed cost repair at £255.This will give potential buyers of Ariston boilers an… Read Full Review

“STAY AWAY!!!!”

Written on: 26/08/2015 by TWHeating (1 review written)

Attended a breakdown yesterday where the customer had no paperwork and boiler was only 9 months old. Called technical department! Tried for an hour to get through, but no one answered...... Rang the sales department and they answered straight away and said there was only 2 people I the tech department and they're at lunch! Finally got through to a guy who in my opinion as a gas engineer of 16 years have never spoke to someone on a tech desk who was so unhelpful. Did not offer any advice… Read Full Review

“Keeps cutting out”

Written on: 06/03/2014 by JaylynnGrady1959 (1 review written)

The boiler was only on a two year warranty when it was installed. Now it keeps cutting out. The fault is intermittent. Yesterday the engineer came out and it was working - so I paid him and today it's broken again. Many engineers seem to have no experience of this boiler. The Ariston service centre offered me a locally trained engineer. There is an answering machine and no one has returned my message of four days ago. I would not reommend this brand to anyone… Read Full Review

“Can't give them no stars otherwise I would”

Written on: 26/02/2014

Awful boilers what I find strange is the only favourable reviews seem to come from installers and not end users the exception being newly installed appliances. In my experience these boilers are awful in terms of longitivity and reliability - this can be highlighted in pre 2010 boilers only having a two years warranty and Ariston will not offer any warrant on its repair on these boilers greater than 28 days! this says it all really. The cost of parts does not compare favourably either with… Read Full Review

“DO NOT BUY - 7 YEARS OF HELL!!!!!”

Written on: 23/02/2014

We had a chaffateau boiler fitted, which failed to work properly, got stuck in a fitter vs manufacturer argument and had invalid warranty. Had to go on 'Don't Get Done Get Dom' tv programme to get it sorted!!! Ariston boiler fitted as replacement as they had taken over Chaffateau - worked until just out of warranty and been nothing but trouble since then. Had new pressure relief valve, internal tank exploded so external fitted, air valve sometimes drips and now getting the ignition and flame… Read Full Review

“JUNK AVOID LIKE THE PLAGUE”

Written on: 09/12/2013 by stellastar (1 review written)

Had nothing but trouble with this leaky piece of junk. Customer service is terrible and the product kills itself after the initial warranty. Get yourself some serious insurance if you are going to buy this heap. Avoid B Gas as they have a 99 pound excess. There are companies which have zero excess. I curse the day I had this rubbish installed. Please don't buy! (Ill get my satisfaction some how! :)… Read Full Review

“RUBBISH !!!”

Written on: 24/10/2013 by Anunhappyman (1 review written)

We have an Ariston Clas HE boiler. What a huge mistake !! This is a complete heap of junk that has broken down every year since two years old! I have insurance every year at extra cost to cover everything that can go wrong, but still took three visits from a qualified gas service engineer to rectify problems. He replaced numerous parts, including the 'mother board' and it worked for one year. Guess what, broken again. Same problem as before, will not heat the water etc. I have since spoken to… Read Full Review

Good when it works but bust half the time... complete JUNK avoid like the plague. Constantly leaks, plumbers always complain that they are too complicated something always going wrong and Ariston are very unhelpful. Parts are hard to get... Depressing bit of kit to have.

“Avoid at all costs!!!”

Written on: 07/09/2013 by simon V (1 review written)

We had the Ariston Clas HE 30 combi boiler installed in 2007, since then every year, several times a year, we have had problems with it. From minor water leaks to a complete master board replacement. If you must opt for this boiler, ensure you have a good breakdown cover policy, a separate source of heating and another way of creating hot water. Ensure you keep a copy of the manual and all receipts of work carried out. Other than that the boiler is fine... … Read Full Review
