  • Commercial grade enamel – provides tougher, longer lasting finish than standard domestic enamels
  • Thicker sacrificial anode – provides additional protection for cylinder against water borne contaminants
  • Twin element model (492315) available. Provides a daytime boost for high demand hot water use
  • Suitable for connection to lower cost tariffs – resulting in lower running costs
  • Manufactured in Australia


Rheem ‘491/492’ series electric water heaters are built to last. The cylinder dome top has been redesigned to make it even stronger, making it better able to withstand the effects of high temperature and pressure.


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.
