NEW! – This is a 3kw, 16″ immersed length BESZB 340 Titanium Heavy Duty Immersion Heater complete with combined (operating & safety cut-out) plug-in thermostat and is typically used within standard unvented domestic water cylinders. Our new design of Titanium Domestic Immersion Heater is engineered with a longer Low Watts Density element which along with it’s titanium sheath is designed to give a higher resistance to limescale attack particularly in Hardwater areas. This design of titanium domestic immersion will provide a prolonged operational life than standard Incoloy sheathed immersions in more aggressive applications with abnormal water chemistry such as Borehole supplies.

Installed products will often carry the ThermTec brand which is owned and manufactured exclusively by Heatrod Elements in Manchester. The BESZB 340 can be used in all standard domestic water areas and is particularly designed for installation in hard water areas susceptible to limescale.

Both Cotherm TSE00187 and Thermowatt RTS-3 dual function thermostats can be used with this immersion heater – see our “Thermostats & Controls” section for more details and to purchase these products.
