The Ariston E-Combi ONE and E-System ONE boilers are mid-range boilers. They are wall-mountable but are larger than some competitor boilers in the market.
This review will go through the details further so you can make the right choice for you.
The Ariston E ONE range (both combi and system boilers) is a great choice for apartments and smaller homes. It should be easy to install in a cupboard, hiding it away and it will integrate with smart technology…if you want it to. The E range comes with a standard 2-year warranty for peach of mind.

The Ariston E-range is a good boiler for smaller homes. The E-Combi ONE is great for smaller properties with 1 or 2 bathrooms. The E-System ONE will require a hot water cylinder to provide hot water.
The E-range comes with a relatively short warranty of two years. This may put a lot of people off these particular models. In our experience, they are a good model, but there is no peace of mind for the long-term like with their Alteas model or a Viessmann 100-W boiler.
A global brand
Ariston has won awards for its boiler design, although not for this particular model. They have steadily built a reputation for reliability and improving performance. However, it is worth noting that their energy efficiency ratings, while high, can be beaten by competitors.
Smart technology
The Ariston E-range ONE boilers feature Ariston’s patented Xtratech™ stainless steel heat exchanger for improved reliability.
This model is also compatible with the Ariston Net system, accessible via a mobile app. You can manage your system from anywhere with the flexibility to control heating remotely.
Reduced household energy consumption
Ariston is making great strides when it comes to creating environmentally friendly products. For example, this boiler comes equipped with a high-efficiency pump. With a 94% energy efficiency rating, your home will benefit from reduced gas bills. And these boilers will help reduce your home’s carbon footprint.
On-demand hot water – combi boiler version
The E-Combi ONE will provide a minimum of 10.4 litres per minute hot water flow rate. This instantaneous heating will reduce energy waste and also helps to reduce inefficiency in your home.
Wide availability of parts
Although not manufactured in the UK – Ariston is still a leading boiler manufacturer. Parts are widely available because of the broad adoption of the Ariston E-Combi ONE. If you need a replacement item, you can find spare parts at Screwfix, Plumbase and other plumbing merchants, both in-store and online.
