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.

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.
