Immersion Heaters & Accessories

Single & Dual Element Immersion Heaters

Thermotec single and dual element domestic immersion heaters are fully approved and tested by NEMKO to comply with the new European Standard EN60335.2.73 and carry the CE mark of approval. They are made in the UK, and can be supplied with elements of either Copper or Incoloy (high nickel alloy), fitted into a 2¼” BSP Brass boss. Copper elements are suitable for non-aggressive and soft water areas whereas Incoloy elements should be used where potentially aggressive water conditions occur. The heaters are available in both single and dual thermostat versions.


Single & Dual Thermostats

Thermotec single thermostat, single and dual elements immersion heaters are fitted with the highest quality IMQ approved Thermowatt Thermostats, which incorporates a resettable secondary thermal device that will operate and trip out if the water temperature exceeds 95°C, thus preventing severe scalding and possible system damage. If the trip switch operates, it can be reset without the need to remove the terminal cover, providing additional consumer safety.

Thermotec dual thermostat, dual element immersion heaters are fitted with Sunvic BEAB approved safety thermostats incorporating thermal fuses providing the same degree of protection against excess water temperatures as the single thermostat heaters. These heaters are recommended for use in indirect systems where the external heat source is from a coal fired boiler, the single thermostat heater is preferred within such a system.
