Description

Experience endless hot water with the Rheem Eclipse 18kW continuous flow hot water heater. Engineered for instant performance, this instantaneous electric system heats water precisely when you need it—no storage tank required.

Hot Water On Demand

Forget waiting for tanks to heat. The Eclipse activates at 2.8L/min flow rate, delivering hot water instantly. Whether multiple showers run simultaneously or you’re filling a bath, this system keeps pace with your household demands. Three-phase power ensures consistent, powerful performance.

Space-Saving Design

At just 470 mm high, 226 mm wide, and 95 mm deep, the Eclipse fits discreetly in kitchens, bathrooms, or laundries. Its compact form factor makes installation straightforward in homes where space is at a premium. Indoor installation keeps the unit protected and out of sight.

Rheem’s engineering excellence shines through every component. The heat exchanger carries a 5-year warranty for residential use, protecting your investment long-term. Parts and labour coverage provides 1-year protection across the system, ensuring peace of mind from day one.

Energy Efficiency Without Compromise

Continuous flow systems heat only what you use. You eliminate standby losses associated with storage tanks, meaning lower energy consumption and reduced utility bills. The Eclipse delivers hot water efficiency without sacrificing performance or comfort.
