Meet the Rinnai Efinity

For over 50 years, Rinnai Australia has delivered reliable, innovative comfort solutions nationwide. Combining local engineering and manufacturing with a strong focus on sustainability and performance, Rinnai is a trusted name among plumbers, builders and specifiers.

With the building industry continuing to evolve, there is an increasing shift towards fully electric systems, driven by improved efficiency, reduced emissions and the growing push toward decarbonisation.

As part of this progression, Rinnai developed its first ever fully electric continuous flow hot water system, the Rinnai Efinity.
