SP6 Series


Introducing Rinnai’s highest efficiency ducted gas heaters, the SP6 series. They are cleverly engineered to use less gas than traditional ducted gas heaters. This is achieved through a 4-pass heat exchanger with modulating gas valve—meaning you get superior temperature control and greater efficiency.

In heating mode, Rinnai ZonePlus™ allows you to independently zone different temperatures throughout the home with the option to turn off ones not in use, saving you money on running costs.
