Ariston confirms its commitment to developing innovative renewable products, with the launch ofNUOS, a new floor standing unvented cylinder with integrated air source heat pump water heater. Using a thermodynamic cycle to heat domestic hot water quickly and proficiently, NUOS has been designed as an energy efficient alternative to traditional (electric storage) water heaters.
Available as a 200 litre direct or 250 litre indirect model and with a CoP of 3.7, NUOS is capable of raising the water temperature to 55°C with just the heat pump (a back-up immersion is present to bring the temperature to 65°C) making it an ideal solution for off gas properties or as a replacement for existing electric only cylinders. Plus, the high quality steel cylinder is 12 bar pressure tested and glass-lined to increase durability.
The NUOS also features an intelligent control system which allows the end-user to set the time hot water is required. The product will then intelligently determine when to start heating the water to achieve the desired temperature, at the required time. In addition, three mode options are available, including; ‘Eco’, ‘Fast’ and ‘Auto’. ‘Fast’ mode requires the heat pump and heating element to work in tandem and can be manually selected by the end- user if hot water is needed quickly, though when ‘Eco’ mode is selected, only the heat pump operates, to deliver maximum energy efficiency and the highest achievable water temperature of 55°C.
In ‘Auto’ mode only the heat pump operates. However, should the set temperature be higher than 55°C, the heating element is activated, in order to save energy and deliver the maximum quantity of hot water. The highest temperature in ‘Auto’ mode is 65°C.
For added peace of mind and to guarantee safety and hygiene, NUOS includes an anti-legionella function, which regularly heats the contents of the cylinder to 65°C in order to sterilise the stored water. Plus, to underpin its quality, the cylinder has a five year guarantee and the electrical components are guaranteed for two years.
The NUOS air source heat pump water heater is a high quality addition to Ariston’s renewables range, which already includes solar thermal packages.
