Stainless steel heat exchangers are exceptionally robust and operate well in a wide range of pH values, providing resistance to corrosion.

142% wider waterways
Wider pipes allow water to pass through the heat exchanger more effectively, with less risk of blockages from debris. This extra width also allows hot water to pass through the heat exchanger quicker.

Better transfer of heat
The enhanced single coil heat exchanger is robust and highly efficient, thanks to an improved condensing surface and increased hydraulic performance. This also allows for constant water speeds and a reduced chance of blockages, ensuring a long lifespan.

Continuous coil heat exchanger
Being manufactured from one continuous coil improves energy efficiency while ensuring smoother running of boiler.

TÜV Rheinland certified
Tested and certified for safety, quality and usability by a renowned, independent European body, the TÜV mark offers reassurance to installers and end users alike.

All ONE Series boilers include a built-in ‘AUTO’ function, which enhances boiler performance and aids energy efficiency. It monitors the ideal temperature for the heating system – reducing peaks in flow temperature and optimising efficiency. Activating the function enables the boiler to automatically choose the ideal output for the central heating circuit, by gradually increasing in power until a room reaches the set temperature, while guaranteeing no excessive peaks. With the ‘AUTO’ function activated, the boiler consumes less gas and electricity, avoiding on/off cycles and fluctuations in flow temperature. When used alongside the latest heating controls, further savings can be achieved. For example, when used in conjunction with an outdoor sensor with a modulating control, savings in excess of 6% can be achieved compared to a standard condensing boiler without similar controls.

Another function available is ‘COMFORT’ mode, which ensures the water contained inside the secondary (plate to plate) heat exchanger is kept in a pre-heated condition. Turning the ‘COMFORT’ function on ensures the boiler can deliver domestic hot water almost instantaneously when required. This innovative feature keeps the secondary heat exchanger warmed up, even during periods of inactivity. Benefits of this function include reduced heat up waiting times and less cold water wastage.

An LPG conversion kit is included in the box of every ONE Series boiler. This allows the boiler to be fitted in properties and applications located in off-mains gas areas, while retaining all the benefits associated with Ariston’s high efficiency products.
