About Rinnai hot water
Rinnai Systems We Work On
Rinnai built much of its Australian reputation on continuous flow technology specifically, and it remains one of the most commonly installed continuous flow brands in the country. Most of the Rinnai call-outs we attend involve continuous flow units — ignition faults, error codes, or flow sensor issues — though we also service their storage and heat pump ranges.
As with every brand we work on, we're an independent service provider rather than a manufacturer-authorised agent, focused on getting your system diagnosed correctly and repaired properly the first time.

Yes — this is a common upgrade we handle, including assessing your existing gas supply and flueing for compatibility.
Yes — while Rinnai is best known for continuous flow, we also service their storage and heat pump product lines.
