Description
Never run out of hot water again. The Rinnai Efinity 14kW Continuous Flow Hot Water Heater uses advanced instantaneous technology to deliver endless hot water precisely when you need it.
Unlike storage tanks that consume energy keeping large volumes hot, the Efinity heats water only as it flows through the system. The powerful 14kW three-phase electric element ensures rapid, consistent temperature delivery—perfect for busy households with multiple outlets and simultaneous usage. Enjoy unlimited showers, full baths, and kitchen use without compromise.
The ultra-compact design is just 103mm deep, making it ideal for kitchens, laundries, or tight cupboards. This sleek profile means maximum interior space efficiency. The IP25 splash-proof rating ensures safe indoor installation in any room.
Penrith Hot Water supplies and installs the Rinnai Efinity 14kW across Penrith, Emu Plains, Kingswood, Glenmore Park, Cranebrook, and surrounding suburbs in the Greater Nepean. We handle full assessment of your three-phase power requirements, recommend ideal placement, and provide professional installation that ensures peak performance.
Energy efficiency is built-in. The system activates at just 2.5L/min, making it highly compatible with water-saving fixtures. You only pay to heat the water you use—no standby losses, no wasted energy. Lower bills and environmental responsibility go hand-in-hand.
The Rinnai brand reputation speaks for itself. The Efinity delivers the industry-leading quality and engineering standards you expect. Five-year warranties on the heat exchanger and parts and labour (residential use) reflect Rinnai’s confidence in this premium system.
