Rinnai Australia Reviews 2

My retired father (on a disability pension) had a Rinnai B16 outdoor hot water system installed professionally as part of a “premium” granny flat from Same Day Granny Flats in mid-2024. Less than a year later, the unit failed completely due to ant infestation. Rinnai refused to cover it under warranty and charged $380 for a technician callout—that’s a full week’s pension gone.

This was an outdoor unit, installed by a licensed plumber, in a completely normal Queensland environment where ants are common. A brand like Rinnai should build appliances that can handle local conditions, especially when marketed as reliable and long-lasting.

Terrible customer service, no compassion, no accountability. We’ll never use Rinnai again—and others should think twice.

I previously had a Brivis ducted contour evap. system for 12-15yrs and it never gave me me problems. Since replacing my old system around 4 years ago, after Rinnai took over the company, I've had nothing but repairs and breakdowns. Extremely dissapointed in this system although have not had any issues with parts being supplied under warranty. Luckily until now it has been covered by warranty but i have grave fears for what is to come. Would not recommend at all.
