The Rinnai external version HDC1200e gives end users 105.5% net efficiency* because the condensing process delivers up to 95% thermal efficiency, translating to significant energy savings when compared to standard tankless water heaters. The only time the unit is using energy is when there is a demand, in other words it is only burning gas when a tap or shower is being run and, design improvements by Rinnai have increased the lowered NOx levels and increased efficiencies to market ready levels. All of which makes the HDC continuous flow hot water range by far the best option for all types of applications. The Rinnai 17e is designed for use directly off the mains, with no need for large, ungainly storage vessels. Weighing just 17kg and measuring 503mmH x 355.6mmW x 181mmD the Rinnai 17e has been developed to allow maximum flexibility as it can be easily mounted on an external wall thereby eliminating the need for flueing and freeing up valuable interior space. With a continuous flow water heater you can never run out of hot water no matter how many individual baths or showers or delivery points are being used simultaneously. 73 This feature gives greater flexibility at the design stage and can offer an alternative solution where flue runs are problematic or internal space is not available. A range of external ancillary items including a pipe cover box and security cage are available where necessary. Capable of flow rates of up to 510 litres per hour at a 50°C rise, the 17e is suitable for multiple applications, such as cafés, small restaurants and kitchen facilities.
