Why we stock the Rheem.
The Xwell Slim Classic Plus is the low-profile option in Rheem's Xwell range. Choose the 20-litre XS-20 or 30-litre XS-30; both use an enamel-lined inner tank, sacrificial anode and insulated casing. Rheem describes its RheemHot+ diffuser as providing more hot water for longer showers. The slim body is intended for tighter ceiling spaces.
The displayed starting price is a GST-inclusive supplier reference checked on 20 August 2026 and rounded to the nearest dollar. We confirm stock and the exact final quote before you order. Installation is separate: send us a photo of the current heater or intended location so we can check access, mounting, pipework and wiring. Any new or altered fixed wiring is assigned to an EMA Licensed Electrical Worker.
