Ariston has added the Clas ONE R to its ONE Series range of condensing gas boilers. Replacing the Clas HE R, the new regular boiler is quiet and compact, as well as a retrofit product for use in an open vented system. The company says it has an impressive, modern design, complete with a large backlit display, offering a wealth of energy saving features.

Available as the Clas ONE R 24, this new boiler shares many of the advanced features for which Ariston’s ONE Series is known for. These include the patented stainless steel, continuous coil proprietary XtraTechTM heat exchanger, complete with 40% wider waterways, alongside low NOx ratings (53mg/kWh).

The boilers are also ‘A’ ErP rated for optimum energy efficiency and, for added peace of mind, are supplied with an eight year manufacturer’s warranty as standard.

The wider waterways of the XtraTechTM heat exchanger allow water to pass through quicker and more effectively – ensuring less risk of blockages from debris. The component is robust and operates well in a wide range of pH values, providing resistance to corrosion and prolonging the lifespan of the boiler.

Every XtraTechTM heat exchanger also benefits from an improved condensing surface and increased hydraulic performance, which combine to provide a better transfer of heat. Plus, it has been independently certified for safety, quality, and usability by renowned European technical testing organisation TÜV Rheinland, offering reassurance to installers and end-users alike. The heat exchanger, as with all major components, is also Ariston branded for "complete confidence in quality", the company says.

Easy to use and install, the new regular boiler benefits from Ariston’s ‘Auto’ function technology, which gradually increases a system’s water temperature until the central heating has reached its target. When used in conjunction with the company’s extensive range of controls, this function guarantees no excessive peaks in flow temperature, ensuring greater levels of comfort, as well as reducing energy bills.

Each boiler has an auto-diagnostic system and an anti-frost device, providing optimum reliability, while an advanced range of wired and wireless controls are also available.

Commenting on the new model, Victoria Gutierrez, Marketing Manager at Ariston, said: “The Clas ONE R is a fantastic addition to our range of condensing boilers. Its heat exchanger has wider waterways designed to prevent blockages, which is especially beneficial for traditional, open vented systems. Its compact dimensions are also perfect for installation inside a cupboard, while the warranty further makes it great value for money.”

The Clas ONE R 24 is suitable for larger properties, working with a storage cylinder to supply volumes of hot water to many outlets, allowing multiple showers and taps to be used simultaneously without affecting the running of the system.
