Rinnai Sunmaster Gas Boost


Rinnai Sunmaster Gas Boost

Gas boosted solar hot water systems are unbeatable in their efficiency. So save the environment and in the long term see great return on investment with a gas boosted solar hot water system. See Gas Work’s to find out which boosted solar hot water solutions will work better for you. See the range of gas boosted systems below.

Rinnai Sunmaster Gas Solar Water Heaters

Rinnai draws from over 40 years experience in designing and manufacturing Hot Water Systems. The Rinnai Sunmaster range of Solar Hot Water Systems have been designed specifically to make the most out of harvesting free energy from the sun with an affordable outlay. 

Available in both Close Coupled and Split Systems

Closed Couple

A close coupled solar system is where the storage tank and the Solar Collectors are coupled together and the installation is on the roof. 

Rinnai Sunmaster close coupled solar systems use the thermo-syphoning principle (i.e. hot water rises because it is less dense) to circulate the water through the Collectors and then to the storage cylinder without the need for a pump.  

Split Systems

A split system is where the storage tank and the Solar Collectors are split and installed separately.

A solar control unit ensures the water circulates between the Solar Collectors and the storage tank. This transfers heat from the Collectors to the water in the tank if enough heat is available from the sun. An electric element or a Rinnai gas booster mounted either on a wall or on the side of the tank will boost the temperature of the solar heated water if necessary.


  • Streamlined appearance ? minimal impact on the aesthetics of your roofline with only the collectors visible
  • Cost effective glass lined (Vitreous Enamel) cylinders
  • Tall slimline tank design with a smaller footprint for minimal aesthetic impact
  • Continuous Flow Gas Booster ? same technology as the Rinnai INFINITY
  • Electric boosted packages featuring optimized element position
  • High efficiency flat plate collectors with frost protection down to -6?C
  • Evacuated tube systems available for frost protection downto -12?C. (refer to separate brochure).
  • Easy installation or conversion on rooves
  • Ground mounted tank can be installed internally or externally
  • Gas or electric booster ensures that you will never run out of hot water
  • Collectors and the tank do not need to be installed at the same time
  • Split systems do not require reinforcement of the roof structure,as the weight associated with water storage is at ground level
  • High performance resulting in high Small Scale Certificates awarded
Features & Benefits
  • Low heat loss due to greater insulation
  • Gas or electric booster options
