Rinnai’s trio of low NOx, one-person lift products is designed to offer high-performance continuous flow hot water heating for all applications.
Rinnai’s Infinity range of 11i,17i &17e ErP A-rated continuous flow gas fired water heaters is specifically designed for low NOx domestic/light commercial use and guarantees the highest efficiencies and lowest running costs at consistently accurate temperatures 24/7.
The range of continuous flow – sometimes referred to as ‘multi-point’ – water heating units is being specified and installed for domestic/residential sites including: cafes, pubs, restaurants, offices, shops, hairdressers, commercial units, caravan parks and leisure facilities as installers and end users become increasingly aware of their energy saving benefits.
The increase in uptake is said to be because Rinnai’s low NOx continuous flow heater systems are proven to be more energy efficient than storage systems and are becoming the experts’ preferred method of hot water provision. The word is out that the Rinnai units easily cater for projects that need high volumes of water at intermittent times of day delivered at accurate temperatures to ensure user comfort and safety. They are also easy to operate and simple to install and maintain. Plus, they are all low NOx, satisfying the Eco-design regulation.
The Infinity 17i unit, for example, eliminates fluctuations in water temperature – meaning no more cold showers or scalding hot baths. The water temperature you set is the water temperature you get. So, if somebody is happily showering at 42°C and a tap is turned on to draw a bath elsewhere in the property, the temperature does not vary, and there is no chance of either user running out of hot water.
The Rinnai Infinity 17i interior model measures 675 by 370 by 139mm and weighs in at just 18kg. The room sealed unit has a temperature range of 35 to 60°C with direct electronic ignition. Gas consumption ranges between 4.7 and 34.9kW for Natural Gas and 4.9 to 36.8kW when using LPG. Hot water delivery flow is 16l max flow and 2.4l/min minimum flow. Nominal operation pressure is 1 to 7 bar and it uses a 230V AC 50Hz 1ph power supply with an electrical consumption of 68W.
Where an external installation is required, the Rinnai Infinity 17e external continuous flow water heater offers greater flexibility at the design stage and delivers a viable solution where flue runs are problematic or internal space is not available. Capable of flow rates reaching 510 litres per hour at a 50°C rise, the 17e is suitable for multiple applications and can be specified for use with Natural Gas or propane.
The 17e has full frost protection and is available with a range of external ancillary items, including pipe cover box – and security cage where necessary.
The Infinity 11i interior unit differs from the 17i as it weighs 2kg less (at 16kg) and consumes 6.1 to 21.6kW of Natural Gas.
Under ACOP L8 (Legionella guidelines), continuous flow water heaters are favoured as the units are normally positioned close to the outlets – in restaurants for example, where the system turnover is frequent and store volumes are small – meaning legionella risk is minimal.
