  • Best energy ratings. Rinnai hot water systems have high energy efficiency and ratings, which cut costs on energy bills. It is environmentally friendly as well.
  • Status monitor. Each unit has a display screen showing the temperature of the water system, which you can set to any figure you wish. The Status monitor is important as it helps identify faults in the system by showing error messages. But, Rinnai has one of the best hot water equipment in Australia, so you’ll rarely see any error messages.
