Rinnai — common questions
My Rinnai Infinity is showing a fault code — can you fix it?
Yes. Rinnai fault codes point to specific issues our gas fitters diagnose regularly, from ignition faults to water flow and gas supply problems. We'll identify and repair the cause.
Do you service Rinnai gas heaters?
We service, safety-check and repair Rinnai gas heaters. Regular servicing keeps them efficient and, importantly, safe.
Can you install a new Rinnai continuous flow system?
We supply, size and install the Rinnai Infinity continuous flow range, matching the unit to your home's hot water demand and gas supply.
How often should a Rinnai system be serviced?
We generally recommend a service every couple of years, and before winter for gas heaters, to maintain efficiency and safety.
