Ariston Clas Net One Combi Boilers

Ariston Clas Net One Combi Boilers typically cost between £1,314.95 and £1,409.95 including VAT and excluding installation.

Clas Net One Combi

The Ariston Clas Net One Combi is an extremely quiet condensing combination boiler that is available in three outputs of 24kW, 30kW and 38kW to suit most homes.

It measures 745mm (H) x 400mm (W) x 385mm (D) and does not require a cold water tank or hot water cylinder to perform. Although not small enough to fit inside a standard-sized kitchen cupboard, this lightweight model can easily be hung on a wall and located in various rooms within your home.

Clas Net One Combi prices start at around £1,314.95 and go up to £1,409.95, which does not include the cost of installation. When it comes to cover, you’ll get a lengthy 12-year warranty to keep you protected against any boiler faults.

Boiler Energy Efficiency Credentials

With an efficiency rating of 90%, the Clas Net One Combi is an A-rated boiler that has been endorsed by the Energy Saving Trust. It is equipped with an Ariston Xtratech stainless steel heat exchanger that is specially designed to improve performance and efficiency levels. The boiler also has an ‘auto’ function which, when activated, makes sure the unit consumes less gas and electricity to help optimise energy efficiency. What’s more, this model can be used with a range of optional accessories including an outdoor sensor so that further savings can be achieved.

Clas Net One Combi Technology and Main Advantages

Promising to perform better and more efficiently than ever, the Ariston Clas Net One Combi features a user-friendly display panel with intuitive buttons to make adjusting temperatures a breeze. There is the energy-saving ‘auto’ function that we mentioned above, along with a ‘comfort’ mode that ensures the boiler can always supply hot water when needed.

The range includes three output sizes with different maximum hot water flow rates, which are as follows:

  • Clas Net One 24kW Combi – 10.4 litres per minute
  • Clas Net One 30kW Combi – 12.5 litres per minute
  • Clas Net One 38kW Combi – 15.5 litres per minute

Installation is straightforward because the flue, wiring and connections are simple to fit, and the boiler is easy to set up thanks to the colour coded wiring, low voltage connections and circuit board. As the components can be accessed via the front and there is more room inside the unit for engineers to work on the boiler, installation and servicing are neater and less disruptive.

On top of all of that, the Clas Net One is built with an improved silencer and the latest soundproofing technology to minimise the overall noise levels, which are similar to the noise levels of a fridge freezer.

Is the Ariston Clas Net One Combi the Right Boiler Type and Size for Your Home?

This unit is fairly compact and doesn’t require any bulky tanks or cylinders, making it a great option for properties with limited loft and storage space. Plus, this model comes in three outputs, so there’s a solution to suit small, medium and large-sized homes. As a rough guide, the 24kW unit should satisfy the needs of a flat or small house with 1 bathroom and around 10 radiators, and the 30kW is best suited to medium dwellings with 1 bathroom, 1 ensuite and up to 15 radiators. The 38kW is for larger homes with 2 bathrooms and higher heating and hot water demands. However, this information won’t be accurate for every household, so you must consult a Gas Safe engineer to help you choose the right size boiler to satisfy your requirements.
