rinnai gas hot water unit

Rinnai Gas Continuous Flow Hot Water Units

Rinnai gas continuous flow hot water units (also called instantaneous or instant hot water) provide hot water only when you need it, rather than storing and reheating water throughout the day. This means you can run multiple taps or showers without worrying about the hot water running out. The compact, tankless design also frees up valuable space and suits modern homes.

Advanced electronic temperature control keeps water consistent and safe, while efficient gas operation helps reduce running costs compared with older storage heaters. Built for Australian conditions and trusted for decades, Rinnai continuous flow units are ideal for families, busy households, and homes with higher hot water demand.

Rinnai Heat Pump Hot Water Units

Rinnai heat pump systems use heat from the surrounding air to warm water, rather than generating heat directly. This makes them significantly more efficient than traditional electric storage units and far cheaper to run over time.

Because they rely largely on renewable energy, heat pumps help reduce electricity usage and household emissions while still delivering dependable hot water year-round. Available in a range of sizes, they can suit small households through to large families.

Heat pump hot water benefits

  • Very low running costs
  • Reduced environmental impact
  • Consistent hot water supply
  • Suitable for solar friendly households
  • Potential eligibility for government rebates – call us for advice

smart rinnai hot water unit

Rinnai Smart Hot Water Units

Rinnai’s smart hot water solutions give you greater control over how and when your water is heated. Using compatible controllers and mobile app connectivity, you can schedule heating times, adjust temperatures, and monitor usage directly from your phone. This allows the system to operate around your routine instead of heating continuously, helping reduce energy consumption and running costs. Smart functionality is especially beneficial for homes with rooftop solar, as heating can be timed for daylight hours to maximise solar self-consumption while still ensuring hot water is ready when you need it.
