Hot Water Systems
Instantaneous Hot Water
Continuous-flow systems heat water on demand — never run out, smaller footprint, lower running costs than storage equivalents.
Continuous-flow systems heat water on demand — never run out, smaller footprint, lower running costs than storage equivalents.
Instantaneous (or 'continuous-flow') gas systems heat water as it flows through a finned heat exchanger — only when you need it. They're the dominant choice for new Australian homes for good reason.
We install Rinnai Infinity and Rheem Continuous-Flow ranges, sized to your peak flow requirement (number of bathrooms, fixtures running simultaneously).
Almost never. Continuous-flow systems heat water on demand — every Rinnai Infinity model is rated for 6+ outlets running simultaneously with stable temperature. Practical answer: even a large family running multiple showers + dishwasher + laundry at once has zero issue.
20+ years with annual servicing. The Rinnai Infinity range carries a 12-year heat exchanger warranty — industry-leading. Modern continuous-flow systems easily outlast traditional storage tanks.
Yes — most Rinnai and Rheem continuous-flow units have a pre-heat option that keeps the heat exchanger warm, delivering hot water within 2–3 seconds of opening the tap. Optional add-on, slightly higher running cost.
