Rinnai Hot Water Systems FAQs
Got questions? We’ve got answers — here’s everything you need to know before booking.
Why does my Rinnai Infinity go cold mid-shower?
Usually a flow sensor or temperature control fault. Our technicians repair Rinnai Infinity continuous-flow systems the same day.
Are Rinnai hot water systems reliable?
Absolutely — they’re one of Adelaide’s most trusted continuous-flow options, offering endless hot water and 6-star efficiency.
Why is my Rinnai showing an error code?
Common codes (11, 12, 14) mean ignition or flame sensor issues. We can reset and service your unit onsite.
Can I replace my old tank with a Rinnai system?
Yes — we remove your old storage tank and install a Rinnai Infinity or Hotflo wall unit with all gas compliance handled.
How long do Rinnai systems last?
10–15 years with annual maintenance. Regular flushing prevents scale buildup.
