The Ariston Boiler Range
Ariston offer a range of condensing boilers: combi, system and regular units are available.
Combis tend to be the most popular in the Ariston range, due to their ability to save space in small-medium sized properties.
You’ll need a combi boiler if you don’t have a water tank or cylinder.
The current Ariston combi boiler range consists of:
- Clas Net One
- Alteas Net One
- Genus Net One
- Clas HE Evo
- E-Combi Evo
- Clas One
- E-Combi One
For combi boilers, you’ll have a range of 24kw to 38kw boilers available, suiting anything from a small flat, through to a 4 bedroom house.
The regular range is a little thin on the ground, with just the Clas HE Regular on offer, and only a 24kw available.
For system boilers, you’ll get more choice, including:
- E-System One
- Clas System One
- Clas HE System Evo
- E-System Evo
Depending on model, there’s a good range of 18kw-30kw system boilers on offer.
Which Size Ariston Boiler Do You Need?
The kw size boiler you need isn’t just dependent on the size of your property, but also the size of your heating system, number of radiators and/or towel rails, and hot water demand (for instance, one shower or two) – it’s not a one-size-fits-all approach.
The easiest way to work out the size boiler you need, is to use this boiler size calculator. By using that, you’ll be offered the most suitably sized boiler for your property (although, they’re Worcester not Ariston), but also an on-screen price.
Now you know the size boiler you need and an indication on price, you can compare that with up to 3 quotes from local installers on an Ariston boiler here, for free.
There are a range of warranties on offer here; they’ll be model dependent.
If you’ve read some of our other boiler reviews, you’ll know we focus on long warranty as being a major selling point. If a manufacturer is only prepared to offer a 1 or 2 year guarantee, there’s a good chance that there’s a reason…
An installation in a small flat could be in the region of £1,900-2,200. But, the boiler only accounts for around half of that cost. Generally, by paying around £100-200 extra for the boiler itself, you can jump from a 1 or 2 year warranty, up to 5 years or more.
Ariston boilers come with a range of warranties. Depending on model, you’ll get 2 years, 5 years, 8 years, or 12 years.
We’d suggest heading for 5 years as an absolute minimum. There’s no need to settle for anything less. For instance, you can get a Worcester Bosch boiler with a 10-year warranty and at a competitive price here.
How Do Ariston Boiler Prices Stack Up Against Other Brands?
Ariston haven’t been known for offering particularly long warranties in the past, and that’s going to put people off, as it doesn’t show they have the confidence in their products that we need to have to buy them.
However, with a range of boilers on offer with the higher range of 5-12 years warranty, their offering is much better now than it used to be.
The problem Ariston have is that they struggle to compete with other leading brands on price. You’d expect a lesser known brand to be cheaper than market leaders like Baxi, Ideal, Vaillant and Worcester.
As an example, you’ll find the Clas Net One 26kw on Screwfix for around £900, around £90 cheaper than the Worcester equivalent. That was, until boiler installation company HEATABLE came to the market. Due to them getting preferential rates, you can get a Worcester with a 10-year warranty fitted at a similar price or cheaper. You can check the exact price here.
The problem is, most boiler fitters want to get products from a local merchant in case there’s a problem (so they can get it swapped instantly), and then you’re talking around the same, or more expensive than the Worcester, Ideal Baxi and Vaillant equivalent.
How Much Does An Ariston Boiler Cost To Install?
And, it doesn’t stop there. A lot of manufacturers are now venturing into installations, one way or another.
Take Worcester for instance. The folks at HEATABLE — a fixed price boiler installer — get Worcester boilers dirt cheap and installation prices are reduced due to removing the need for quotations and sales reps, so they compete with local installers and blow national firms out of the water.
Expect prices to for installation to be upwards of £1,770.
We’ve also wrote a full guide on boiler installation here that’s worth a read, including the difference in prices between local and national installers.
Ariston Boiler Reviews
I like to dig out some reviews before buying any product, let alone one that might cost £2,000 or more. The problem with smaller companies like Ariston, is the volume of reviews just aren’t out there.
Trust Pilot is a good place to start. Most here are negative, but due to the lower volume, that might not be a true representation of Ariston’s products or the service on offer. Either way, it doesn’t exactly fill the mind with confidence.
There’s a more varied set of Ariston boiler reviews over on the Review Centre.
More interestingly, there’s a review that includes a customer survey over at Good House Keeping.
84% of readers there rated Ariston boilers as “good or excellent which is a slight contrast to what’s being said on Trust Pilot.
Review Verdict: Should You Buy An Ariston Boiler?
I wouldn’t be against an Ariston boiler, nor be upset if one was already installed if I moved into a property. However, with lack of reviews online and prices comparable to leading brands like Baxi, Ideal Boilers, Vaillant and Worcester – I’d be sticking with one of those brands.
However, prices may vary depending on your installer. If they fit a high volume of Ariston boilers, there’s a good chance they get amazing deals, and can fit them much cheaper than your average installer.
