FOCUS ON BOILERS
MANUFACTURER - NAVIEN
NAVIEN UK TECHNICAL DIRECTOR SEAN KELEHER DISCUSSES HOW THE FIRM’S AWARD-WINNING RANGE OF NEXT-GENERATION BOILERS HAS LED TO A NEW COMBI CROSSOVER CATEGORY… Reinventing what is possible for hot water comfort
A global operator with a 45-year heritage in the heating business, Navien is supplying the Irish market with its NCB ON range of boilers delivering consistently hot water in larger homes without a cylinder. Traditionally, combi boilers have been unsuitable for installation into larger multi- occupancy properties, particularly those with several bathrooms or en-suites. Navien has broken the mould with its ON technology, delivering a combi boiler without the cylinder, slow heat-up times or low flow rates. Backed by the efficiency and intelligence of pioneering technology and expert technical support, the range is available with up to 12-years warranty to give customers peace of mind. The NCB ON range has reinvented what is possible in larger homes, with the frustration of showers and taps fluctuating between hot and cold a problem of the past. The boilers within the range are an added bonus for customers who would like to add value to their home by creating space for additional storage or a small WC. Water-adjusting and water-mixing valves within the boilers maximise hot water comfort by using sensors to keep the hot water outlet at a consistent temperature. If water is not hot enough, the water- adjusting valve will slow down the water, so it can be heated up to the required level.

temperature down to the right level. To boost water and energy savings, the NCB700 ON has a built-in secondary circulation pump and comes with a NaviCirc, designed to halt the secondary circulation if it senses the water temperature has gone above 35°C. This gives a fast hot water draw-off time and guarantees consistently hot water in customers’ homes, with the whole process taking an industry-leading nine seconds. All components, including the PRV, are easily accessible and identifiable to fix faults quickly and the boilers feature a keyless filling loop, the NaviFill, providing an easy method for customers to top up boiler pressure themselves. The NCB700 ON comes with an ErP A+
rating when used with Navien’s Smart Plus controller and boasts flow rates up to an industry-leading 22 litres per minute, an outstanding turn-down ratio of 15:1 and maximised recirculation of domestic hot water. These are just a few of the reasons why the NCB700 ON was voted Domestic Heating Product of the Year at the 2022 Energy Saving Awards. This summer Navien continues their commitment to bringing new innovative boilers to Ireland’s market, with the launch of its NCB500 System Boiler. Ideal for retrofit, the boiler can be installed into existing systems easily and is suitable for both small and large family homes. To find out more, visit https://navien.co.uk/professional
