Commercial Heat Pump

Commercial Heat Pump

Efficient, Reliable, and Built for Australia

Backed by over 45 years of expertise in refrigeration, the Rinnai Commercial Hot Water Heat Pump delivers high-efficiency performance while withstanding Australia’s harsh climate.

Constructed from heavy-duty galvanised steel, it features corrosion-resistant epoxy-coated coils, an integrated primary circulation pump, and a wide ambient temperature operating range. Using the environmentally friendly R513A refrigerant with zero Ozone Depletion Potential and 56% lower Global Warming Potential (GWP) than R134A, it achieves a class-leading Coefficient of Performance (COP).

Smart commissioning and diagnostics via a mobile app make setup and maintenance simple, while flexible installation options and an optional back-up electric heating function ensure reliable operation in any setting.
