What would be the reason for the absence of hot water?

It depends on the type of Rinnai water heater technology you possess:

  • Instant: Your system may have experienced a power loss, a surge protector might have tripped, the gas supply may be worn out, or an error code might indicate an issue.
  • Tank: In the case of a tank system, your Rinnai may have run out of water. You may have to wait 1-2 hours (or overnight) for the tank to refill. If it’s a gas-powered unit, the pilot light may have gone out, necessitating a relight, or stop valves could be closed. A blocked inlet water filter is common across the entire range.

Why is my Rinnai Hot Water System producing excessively high temperatures?

When hot water becomes scalding, it can pose a safety risk, especially in older systems lacking built-in temperature control mechanisms. In such instances, inspecting your system’s thermostat is essential, which might be configured to a high setting. Achieving the desired temperature may require some trial-and-error adjustments. If you encounter difficulties, do not hesitate to seek the assistance of a qualified plumber.

In situations of uncertainty or if problems persist, you can rely on Sydney Plumbing Hot Water for all your Rinnai hot water system needs, including supply, installation, repairs, and servicing in Sydney and its vicinities.

How long does Rinnai Hot Water Systems last?

Rinnai water heaters are designed to endure the demanding Australian environment. Continuous flow heaters from Rinnai have the potential to remain operational for as long as two decades, while storage heaters typically have a lifespan of 8 to 12 years.

It’s worth noting that Rinnai provides warranties for all its heater models. However, the longevity of a heater depends on factors like water quality, usage patterns, and maintenance practices. Regular maintenance can detect issues early on and help avoid costly repairs.

What's the Procedure for Resetting a Rinnai Hot Water System?

In many instances, you can clear the error code by performing a reset on your water heater. For resetting the system:

  • Close the hot water taps. If the error code persists, switch off the unit.
  • Wait a few seconds, then switch the unit back on.
  • If the error code continues to appear, feel free to contact our 24/7 assistance.
