Immersion Heaters

All Heatrae Sadia immersion heaters are fitted with an RDT combined thermostat and re-settable safety cut-out to provide further protection against boiling in compliance with BS EN 60335-2-73.

With lengths from 11" through to 36", the range covers applications requiring both horizontal and vertical mounting.  Three different sheath materials are available for different water conditions.

  • Copper - To suit normal water conditions.
  • Superloy - Nickel alloy for aggressive water conditions.
  • Titanium - For hard and very aggressive water conditions.

The range of RDT thermostats provide a simple method of upgrading existing immersion heater installations to the new standard without the need for draining down the hot water cylinder.
