Ariston helps take care of millions of families

Ariston’s Boiler Range

Ariston are known for their versatility, and have products covering combi, system and regular (open vent) boiler types.

As with many manufacturers, their most popular boiler types are their combi boilers. Their combi boilers in particular save a lot of space, making them ideal for smaller properties with 1-3 bedrooms and 1-2 bathrooms.

Among their many products, the 3 that B T Morgan like to recommend are the Ariston Clas One, the Ariston Genus and the Ariston Alteas.

The Clas One Boiler

This product is the latest addition to the Ariston boiler family.

The first one to come under the spotlight in our Ariston boiler review. With a standard warranty of 8 years, this boiler is designed and built to provide heat to your home for a long time. Fitted with its new Stainless Steel Xtratech heat exchanger, it operates silently in the background thanks to a powerful, high efficiency pump.

Key Features of the Clas One:

  • Easy installation process due to lightweight, compact design of boiler
  • Boiler dimensions 745mm (Height) x 400mm (Width) x 385mm(Depth)
  • Space available for maintenance and manual operation controls
  • A robust design and durable chassis
  • Ariston-branded components provide confidence in the quality of the manufacturer’s products
  • ERP Rated ‘A’
  • Includes LPG conversion kit, wall bracket and tap kit
  • Modulation ratio of 1:7
  • Boilers available as either a 24kw, 34kw or 38kw
  • Compatible with Ariston Cube S Net or Sensys Net, also compatible with other programmable and smart controls like EPH and Nest
  • Built in mechanical clock and pressure gauge
  • A new improved silencer and latest soundproofing technology, provide noise levels between 49-52 decibels throughout the range
  • Each boiler is fitted with an ultra-safe glass panel for easy access

Further Benefits

The Xtratech heat exchanger inside the One series is made out of stainless steel. These heat exchangers are exceptionally robust and provide resistance to corrosion. It has 142% wider waterways – these are wider pipes that allow water to pass through the heat exchanger more effectively. This extra width lowers the risk of blockages from debris.

Robust and corrosion-resistant

Another benefit is the better transfer of heat, due to the internal single coil design. The single coil design has an improved condensing surface and increases hydraulic performance. This allows a reduced chance of blockages, constant water speeds and ensures a longer lifespan.

Other benefits include the ignition control system to automatically detect changes in your gas supply for improved efficiency. There’s also a large LCD display and touch button control system with Wi-fi and timer capabilities, giving you all the control you’ll ever need.

The Genus Boiler

This top-of-the-range boiler from Ariston is another showcase of the stainless steel Xtratech heat exchanger. Inside the unit itself it features the Cube RF modulating room sensor for heat management and smart connectivity.

This newer inclusion to the Ariston boiler family exceeds in efficiency, boasting an impressive ‘A+’ ErP rating* (*If used with the Cube RF modulating room sensor). It also comes with a 12 year warranty as standard.

Key Features of the Genus Boiler:

  • Easy to install thanks to the lightweight design and compact dimensions
  • Space available for maintenance and manual operation controls
  • A robust design featuring durable chassis

Further Benefits

As mentioned in the Clas One range, the Ariston Genus boiler also boasts a 142% increase in waterway width. This allows for a more effective passage of water through the heat exchanger for better efficiency.

It has a new combustion control system, installers simply select the relevant gas setting and the boiler automatically switches to natural gas or LPG without any hassle.

The Alteas Boiler

As perhaps noticed in the rest of our Ariston boiler review, the Alteas One range shares many benefits offered by other boilers from Ariston. Another key benefit for the Alteas is the heat management and smart connectivity that comes right out of the box.

This brand new flagship product pushes the boundaries of efficiency even further with its ‘A+’ ErP rating* (*If used with the Cube RF modulating room sensor). With Boiler Plus compatibility and a standard 12 year warranty included, it’s another reason why Ariston are an excellent manufacturer.

Will I need a Combi Boiler from Ariston?

It’ll depend entirely on the type of property and other factors whether an Ariston combi boiler will be right for you. If you’re considering a combi boiler, you can enjoy any one of the following benefits:

  • Save on space without the need for a storage tank or hot water cylinder
  • Huge energy saving benefits – waste is minimal by operating on an ‘as-and-when’ basis
  • Lower installation cost than other boiler types, with fewer parts to install
  • Your water supply will be safer – By coming directly from your mains supply, it’s now much safer to consume.
  • A stainless steel Xtratech heat exchanger
  • Good range of warranties available – 8 or 12 years (excluding the E-Combi one)

What output range would my Ariston boiler need to be?

Once again, this depends on your property, but their combi boilers have output availability from 24KW to 38KW. This could suit anything from a small 1 bedroom flat, all the way to a much larger, 4+ bedroom house.

You’ll also need to consider the size of your current heating system, how many radiators in the property, as well as the sort of demand you require for DHW (Domestic Hot Water). If you live with a large family for instance, you’re probably looking at needing hot water out of multiple outlets simultaneously.

How does Ariston compare with other brands?

With an excellent range of products seen in our Ariston boiler review available in several different categories, they’ve proven themselves to be one of the market’s leading manufacturers. More importantly however, is how they compare to other brands.

A brand such as Worcester Bosch, Baxi, Ideal or Vaillant may be able to impress you with strong marketing campaigns, but they’re occasionally known to show little interest in looking after customers once their boiler is installed.

You only need to take a quick look on Google to find that some of the more common complaints centre around aftercare – or a lack of.

As we’ve mentioned in our section on warranties, the level of your customer service also lies in the working relationship with your installer. For example, a local company such as B T Morgan can ensure you get the aftercare you deserve.

How much does it cost to install one of these?

Naturally, the cost of a boiler installation depends firstly on the specific boiler that’s most suited for your property. One of Ariston’s best selling points, is they have a very good price point on all their boilers. This means that everything they manufacturer and potentially have installed at your property will be done so at extremely good value.
