About the Rinnai Sunmaster

Technically efficient, low maintenance and economical to install and run, the Rinnai Sunmaster range of solar hot water systems has become a market leader thanks to its intelligent design and ease of use.

Created with efficiency and affordability in mind, the Sunmaster range includes gas and electric booster options, making supplementary heat available so your Rinnai can shine even when the sun doesn’t – and keep the hot water flowing throughout the cold winter months.

Rinnai’s reputation as an industry leader is well-deserved, and the Sunmaster range is the result of over four decades of experience in the design and production of hot water systems.

Rinnai Sunmaster Close Coupled System

Utilising a close coupled design where the storage tank and solar collectors are located in close proximity to each other on the roof, the Rinnai Sunmaster circulates water through solar collectors and into the storage cylinder. This is known as the thermo-syphoning principle and means there is no requirement for a pump.

This system features:

  • 200 or 330 litre storage capacity
  • Continuous flow gas/electric boost are available
  • Efficiency is maximised by enduro collectors’ aluminium fin solar absorber
  • The tank’s temperature is controlled with a sophisticated thermal arrestor
  • A sacrificial anode is included in the tank to prevent corrosion
  • Suitable for high wind areas to classification region D in accordance with AS/NZS1170.2:2011 using our additional cyclone frame
  • Storage tank has 5 years warranty
  • Collectors have 7 years warranty

Rinnai Sunmaster Evacuated Tube Systems

Evacuated Tube Solar Systems consist of a ground mounted storage tank that is installed separately to the tubes mounted on the roof. A solar control unit ensures water circulates between the tank and the header across the top of the tubes.

This system features:

  • A range of storage capacities from 175 litres to 315 litres
  • Available with electric boost or continuous flow gas boost
  • Minimal impact on the aesthetics of your roofline
  • No need to reinforce the roof structure
  • Frost tolerant for temperatures as low as -12° C
  • Solar collectors available in 20, 25 or 30 tube configurations
  • A sacrificial anode is provided in the tank for added protection
  • 15 years warranty on the solar collectors
  • 10 years warranty on the storage tanks
