The reason for the increase in popularity is that continuous flow heating systems are proven to be more energy efficient than conventional ones and are now the preferred method of hot water provision. Rinnai units meet the demands of any size of home and are ideal where high volumes are demanded at intermittent times of the day, delivering safe temperature useable hot water.<\/p>\n
Rinnai’s multipoint 17i water heater, for example, eliminates the problem of sudden changes in water temperature, resulting in cold showers or scalding hot baths \u2013 the water temperature you set is the water temperature you get. So, if somebody is happily showering at 42\u00b0C 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.<\/p>\n
The Rinnai 16i interior model measures just 675 x 370 x 139mm and weighs in at 18kg – a one-man lift. The room-sealed unit has a temperature range of 35\u00b0C to 60\u00b0C with direct electronic ignition. Gas consumption ranges between 4.7kW-6.5kW for Natural Gas and 4.9kW-36.8kW when using propane. Hot water delivery flow is an impressive 16ltr max flow. Nominal operation pressure is 1-7 bar and it uses a 230V AC 50Hz 1ph power supply with an electrical consumption of 68W.<\/p>\n
Meanwhile, where an external installation is required, the Rinnai 17e external multipoint water heater offers greater flexibility at the design stage and offers a viable solution where flue runs are problematic or internal space is not available. Capable of flow rates of up to 510 litres per hour at a 50\u00b0C rise, the 17e is suitable for multiple applications and can be specified for use with Natural Gas or propane.<\/p>\n
The 17e has full frost protection and is available with a range of external ancillary items, including pipe cover box \u2013 and security cage where necessary.<\/p>\n
For smaller properties, the Infinity 11i interior unit differs from the 17i as it weighs 2kg less at 16kg and consumes 6.10kW-21.60kW of Natural Gas and has an 11-litre maximum flow.<\/p>\n
Key features of the 24kW Rinnai 11i are: Compact & lightweight unit for easy installation; Robut, durable heat exchanger; User friendly digital controls; In-built frost protection; Ideal replacement for large obtrusive and bulky cylinder; Compact design to fit a limited space.<\/p>\n
