Ariston has launched its brand new ONE Series range of high performance condensing gas boilers and controls. Comprising three A-rated boiler models – the E-Combi ONE, Clas ONE and Clas Net ONE – the new range combines modern, Italian design with the latest materials and a user-friendly interface. Intelligent, robust and efficient, these are also the quietest units Ariston has ever produced.

The technologically advanced ONE Series boilers boast a patented stainless steel, continuous coil XtraTechTM heat exchanger. With 142% wider waterways than previous models, it allows water to pass through quicker and more effectively – ensuring less risk of blockages from debris. The component is exceptionally 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.

Ease of installation

Lightweight and straightforward to install, with easy frontal access to all components and more room inside the casing, the new boilers have been designed to aid with commissioning, servicing and repair. The chassis is strong and durable, with no sharp edges, while installation is further aided by simple-fit connections, wiring and flue. Plus, not only are the new units fully compatible with the current range of accessories, they also have all connections in the same places – enabling an easy retrofit in place of an existing Ariston boiler.

Fitting controls is made even more straightforward, thanks to a unique colour coding system, which matches parts to a corresponding slot. All major components are also Ariston branded to highlight their authenticity and provide complete confidence in quality.

Enhanced controllabity

ONE Series boilers are fully compatible with the Ariston NET smart heating control, while BusBridgeNet® technology allows communication with other Ariston products. This simplifies integration with a range of devices and heat sources, optimising energy consumption. The remote diagnostic capabilities of Ariston NET also ensure any faults are identified immediately, followed by precise remedial advice.

A brand new suite of controls has also been introduced to allow quick and easy access to Ariston NET. Both the Cube S NET Wi-Fi thermostat and Cube room sensor boast many advanced functions, including energy management, internet weather monitoring and a weekly scheduler programme, as well as holiday and override modes. Thanks to wired and wireless zone management kits, it is also possible to manage up to six heating zones with these controls,

In addition to these controls, all ONE Series boilers include a built-in ‘AUTO’ function, which monitors the ideal temperature for the heating system. This reduces peaks and fluctuations in flow temperature, ensuring the boiler consumes less gas and electricity, while avoiding on/off cycles.

Ariston’s ONE Series range of boilers and accompanying suite of controls will be available from UK merchants and stockists nationwide from 1st November 2017. E-Combi One boilers will have a 2-year warranty, Clas ONE models an 8-year warranty and the Clas Net ONE will benefit from a 12-year warranty.

The Rinnai Infinity condensing boiler range is available for natural gas and LPG operation and comes with innovative controls maximizing energy efficiencies through class-leading weather compensation technology.

The Infinity boiler is A rated under the ErP directive, meaning customers can make an informed decision when purchasing.

The Rinnai Infinity condensing boilers come in 50kW, 75kW and 100kW versions and are both maintenance and installer friendly. The appliances are accessed from the front and require minimal space for installation, thus helping to reduce cost and time required on site. Some of the units also feature a fully removable pivoting heat exchanger and burner for easy inspection and cleaning.

New combustion control technology also imbues the units with the capability to self-calibrate so avoiding manual setting and automatically adapts to suit the gas quality.

The boilers also offer a range of ancillary options including pressurisation units, manifold pipework assemblies, mounting frames, heating system separators, boiler and water heater combination packs, ancillary control options, external temperature sensor
and advanced boiler controls.

The 50kW, 75kW and 100kW versions all have an efficiency of 93%. The CGB-50 measures 855mm x 440mm x 393mm, while the CGB-75 and CGB-100 both present at 1020mm x 565mm x 548mm.

Leading British Manufacturer Keston Boilers has supplied three 55kW Heat Only twin flue boilers and a Frame and Header Kit to Lancing College in Lancing, West Sussex, which have been installed as part of a refurbishment project to improve the reliability of the heating system in one of the accommodation blocks and reduce overall running costs.

Lancing College is an independent boarding and day school, providing education for boys and girls aged 13-18 years. The boilers have been installed in Gibbs House, an accommodation block providing boarding facilities for 650 boys. Like all the buildings at Lancing College, Gibbs House is over 170 years old and the old heating system had previously been served by a central boiler room located in the main building over 50 metres away. The old boilers were not only unreliable and less energy efficient, but the long external pipe run resulted in excessive heat loss, as did the five inch cast iron pipework delivering the hot water to the radiators in the building, all of which contributed to high fuel bills.

The new Heat Only Boilers were installed on Keston’s Frame and Header Kit, which was delivered in prefabricated modules that were then quickly and easily assembled on site by Chris Smith, Heating Engineer. The system was installed in a new plant room within the building, eradicating the need for a long pipe run, and serves 60 radiators. Around 200 yards of new 67mm copper piping runs along four foot high tunnels located throughout the building, ensuring they are out of sight and retain the character of the school.

There are around 30 Keston boilers installed throughout Lancing College and this installation was the first that utilised the new range of Keston boilers, which were launched in 2013. Chris Smith commented, “The Keston Heat Only boilers were very straightforward to install, especially with the Frame and Header kit as supplied by Keston. They have been running perfectly since their installation and the increased energy efficiency has meant a large reduction in running costs for the school.” He added, “The flexible flueing options offered by Keston twin flue boilers were perfect for our needs, as they allow us to hide the flues so they do not affect the character of the buildings by emerging from the original flintwork.”

The Keston Heat Only condensing boiler range includes 45kW and 55kW outputs and it is the only dedicated boiler on the market for domestic or light commercial applications that combines twin flue capabilities with a fully modulating Energy related Products (ErP) approved pump built into the framework of the appliance. Continuing to make boiler efficiency easy for customer and installer alike, the Keston Heat-Only range is also supplied with integrated weather compensation and an outside sensor as standard. Weather compensation is instantly activated when the outside sensor is installed, creating a simple ‘plug and play’ solution with no intricate programming required.

Keston’s boiler range for both domestic and light commercial applications, manufactured in Britain and launched in 2013, includes system, combi and heat-only boilers, all of which incorporate market-leading twin flue capabilities that are highly adaptable, offering the perfect solution for awkward installations. All boilers in the range offer a high SEDBUK efficiency rating, are Energy Saving Trust endorsed and also feature on the Energy Technology List (ETL), qualifying them for inclusion in the Government’s Enhanced Capital Allowance (ECA) scheme.

Rinnai, designer and manufacturer of the Infinity range of continuous flow gas fired water heaters, welcomes the implementation of the Energy Labelling Directive on 26 September as it scores ‘A’ ratings on all its water heaters.

“Energy labelling of product offers transparency to specifiers and end users who will now have a clear guide for choosing the most efficient units available,” said Chris Goggin, Associate Director of Rinnai UK.

“Rinnai brings to market the most extensive range of ‘A’ rated appliances with load profiles ranging from small domestic models to XXL sized industrial units,” said Goggin.

“The ‘A’ rating applies to when a unit is in use – i.e. when fuel is being used, and as an ‘A’ rated Rinnai unit only uses fuel when water is being drawn the energy label crystallises our reputation for efficiency, as continuous flow water heaters suffer no standing losses with storage counterparts”.

When Rinnai water heaters are paired with solar thermal and the latest intelligent controls are used for ultimate heat recovery, even higher efficiencies can be achieved, he added.

Rinnai is also set up to offer installers expert help with system labelling. Installers will be responsible for creating the labels for those installations that combine a water heater with renewables, for example.

On 26 September 2015 The Energy Related Products (ERP) Directive, incorporating Ecodesign and Energy Labelling Directives for water heaters (Lot 2) come into force, meaning that water-heating products sold in the UK will need to meet minimum energy performance criteria in order to be legally placed on the market, and will require an energy label.
