ATER HEAT Water heater inno ation meetsi
Water heater innovat on meets ErP compliance standard W
hen new ErP efficiency requirements for water heaters ca
came into effect in September 2018,many existing appliances
no longer oc mplied. However some water heater manufacturers have been innovating to bring their solutions up to standard.
Among these is the AquaNov a LE by Vokera by Riello which is described as an energy-efficient solution for providing instantaneous domestic hot water tomultiple outlets at a high flow rate.With low nitrogen oxide emissions, this new addition is classified under the Ecodesign of ErP Class A, making it fully oc mpliant with the latest ErP Tier 3 requirements.
This unit is said to suit domestic and small, light commercial applications that require an instant and reliable hot water supply.
“Easy to install and to service and featuring a powerful heat output, our new AquaNova LE offers a continuous supply of hot water, and can be used simultaneously at various outlets while delivering a high flow-rate,” says Alister Maclachlan, product
“In addition, this o director, Vokèra.
c mpact water heater takes up
Vokèra by Riello’s new AquaNova LE instantaneous multipoint water heater
less space than a oc nventional storage tank and virtually eliminates standby losses as energy isn’t wasted when hot water cools down in long pipe runs or while it ’s sitting in the tank.” Delivering a flow rate of 13.2 litres per minute at temperature rise of 35˚C, AquaNova LE can fit appli ac tions where space is at a premium. Continuous gas modulation and electronic temperature sensing ensure accurate temperature oc ntrol for user safety and comfort. A temperature lock function can be used to limit the outlet temperature, while a keypad lock function prevents tampering. The appliance features a digital display and user interface for ease of operation and there is also a fault code display function for diagnostic purposes. For increased efficiency, the appliance’s electronic ignition eliminates the need for a constantly running fan or energy-wasteful pilot light. AquaNova LE is available in natural gas and liquefied
petroleumgas (LPG) versions and is also designed to accept pre- heated water for solar integration. Installation and
commissioning are simple,with all connections easily accessible and a buil -t in fly lead. The appliance is designed for flexible flueing and ac n be flued horizontally or vertically using concentric uni-flue or twin-flue systems. Units also include stand-off brackets required for rear outlet flue exit. Servicing has also been simplified as there is no diaphragm or water section, which redu ec smaintenance requirements.
