    Ariston E-System One System Boilers

    Ariston E-System One System boiler prices start at £739.95 and go up to £793.95 including VAT and excluding installation.

    Ariston E-System One System

    The Ariston E-System One is a stylish condensing system boiler with high-end features and high-performance components.

    It has fairly compact dimensions that measure 745mm (H) x 400mm (W) x 331mm (D) and can be purchased with an output of 24kW or 30kW to suit your needs. As it’s a wall hung system boiler, you can save some much-needed space in your home but you will need a separate cylinder for storing your hot water.

    This model will set you back anything between £739.95 and £793.95, which includes a standard 2-year manufacturer warranty.

    Boiler Energy Efficiency Credentials

    Ariston’s E-System One is ErP compliant and boasts an efficiency rating of 93%, making it an A rated boiler for energy efficiency. It is equipped with an Xtratech stainless steel heat exchanger that provides a better transfer of heat and helps the boiler to perform more efficiently. In addition to this, a special energy-saving ‘auto’ function is included to enable the boiler to use less gas and electricity, as well as automatically choose the right heating output to match demand. The boiler is also Energy Saving Trust endorsed and compatible with a range of optional controls that are designed to aid energy efficiency.

    E-System One Technology and Main Advantages

    With 142% wider waterways, the E-System One allows hot water to pass through its heat exchanger quicker and more effectively to help reduce the risk of blockages. The boiler has an Xtratech heat exchanger (manufactured by Ariston) that is made from stainless steel to provide resistance to corrosion and ensure the boiler has a long lifespan.

    It’s a user-friendly appliance with a smart display panel that benefits from intuitive buttons to enable you to select modes and adjust temperatures with ease. The control panel is where you will find buttons to activate the ‘auto’ function we mentioned earlier and a ‘comfort’ mode which makes sure the boiler delivers hot water when needed. Also, this model has an improved silencer and the latest soundproofing technology to significantly reduce noise levels.

    As the E-System One comes with colour coded wiring, low voltage connections and a decent circuit board, installation is quicker and less disruptive. Plus, not only is there more room inside the boiler for your engineer to do their work but all components can be accessed from the front of the unit, helping to make installation, servicing and repair a whole lot easier.

    Is the Ariston E-System One the Right Boiler Type and Size for Your Home?

    The Ariston E-System One is available in two outputs of 24kW and 30kW to suit the requirements of different property types and sizes. It’s an ideal choice for homes without much loft space because it doesn’t require any bulky cold water tanks, however, you must have a hot water cylinder (usually found in the airing cupboard) with this unit. This model is also a sensible solution for those looking for a boiler that can provide a constant supply of hot water to multiple taps at the same time. As this is only a rough guide, you must ask a Gas Safe engineer to advise you on whether this appliance will satisfy your household’s heating and hot water demands.

    Our Honest Opinion of the Ariston E-System One

    Without question, the Ariston E-System One is an advanced system boiler that offers a lot of benefits and decent components for your money, with one of the best features being the heat exchanger that has been developed by the brand itself. The Xtratech heat exchanger is robust and highly efficient, which is down to the wider waterway, improved condensing surface and increased hydraulic performance – all of which also help to make the boiler more reliable.

    The boiler comes with an LPG (liquefied petroleum gas) conversion kit, meaning it can run on natural gas or LPG is you aren’t connected to the mains. What’s more, it has been tested and certified by TUV Rheinland, a leading independent body that certifies the safety and quality of boilers and other products.

    Taking into account that the E-System One boasts the same build quality and fantastic technology as many boilers that cost a heck of a lot more, we think this model is perfect if you’re on a budget and looking for an efficient system boiler that maximises both comfort and energy savings.
