The Real Difference

Rheem 250L – 400L electric water heaters are designed and manufactured by Rheem,
Australia’s No.1. This new and improved range of products replaces the existing 250L – 400L
Rheem ‘191’ series product range, and features The ‘REAL’ difference. These enhancements
combine to deliver maximum performance and reliability, backed by a 12 year cylinder warranty
and 75 years of local manufacturing experience.


– A thicker 27mm diameter (up from 21mm diameter) black cap anode is fitted as standard to Rheem 491/492 series electric water heaters. This provides more physical material to help protect the cylinder for longer.
Specialty blue cap anode models also feature a thicker 21mm diameter anode (up from 17mm diameter).


– A commercial grade, proprietary blend Class Y enamel provides the cylinder with a tough, durable coating.
It is both stronger and more durable than domestic grade Class X enamels, and being less soluble, will prolong the life of the water heater


– Rheem 250L – 400L products are made right here in Australia. Rheem is a committed Australian manufacturer, with a 50 strong team of local R&D engineers dedicated to providing the best products and knowhow gained from 75 years of local manufacturing
