Rinnai water heater FAQ

How often should a Rinnai tankless be descaled?

With Southern California's hard water, many homes benefit from descaling about once a year. We recommend a schedule based on your water and usage.

What does my Rinnai error code mean?

Rinnai codes point to ignition, flame, venting or sensor issues. Call us with the code and we can explain the likely cause.

Can you replace my tank with a Rinnai tankless?

Yes. We evaluate gas supply, venting and location, then install the right Rinnai model for your home.
