Rinnai Gas Hot Water

For over 35 years Australians have trusted the Rinnai name while enjoying the comfort, convenience and reliability of Rinnai gas appliances. Rinnai gas hot water is available through their gas storage system, gas continuous flow system and gas boosted solar systems.


  • Up front purchase costs are usually less than other types of units.
  • Installation costs are also usually lower.
  • No upgrade of gas line is required.
  • Not as energy efficient as other Rinnai gas hot water systems.
  • Heat loss from the tank results in the heating mechanism being used more often, increasing your energy usage.
  • Tank size takes up space.


  • Unit is small and mounts onto wall, saving you space.
  • Only heats water as you need it, so you will never run out of hot water.
  • Controllers can be installed to accurately deliver required water temperature.
  • An upgrade to your gas line may be required, adding to you upfront costs.
  • Small amount of water (approx. 1 to 2 litres) is wasted in initial delivery. This is dependent upon how far the unit is located in relation to the tap output point.
  • Most units need to be plugged into a power point. If there is a power outage, unit will not work. (Units which do not require an electrical power supply are available).


  • Free energy from the sun.
  • Reduced costs on gas bills.
  • Uses a continuous flow unit for a backup booster, so the hot water never runs out.
  • Higher installation cost.
  • Tank is larger and takes up more space than continuous flow units.
  • Less efficient in winter. (Panels have to be installed on a north facing roof to maximize the efficiency of the sun.)
