ADHTB340 LWD 3kw 16" Immersion Heater

Product Code: ADHTB 340 LWD

This is a 3kw, 16inch Incoloy Immersion Heater complete with separate operating & safety cut-out rod / stem thermostats. Typically used within standard domestic water cylinders. This product will often carry the ThermTec brand which is owned and manufactured exclusively by Heatrod Elements in Manchester.

The ADHTB340 LWD is specifically designed with low watts density aimed at use in hard water areas susceptible to limescale although can of course be used in all standard domestic water areas. If particularly aggressive water conditions are present or the duty/usage is higher than normal then we would recommend a titanium element version which can be priced and manufactured on request.

Both Sunvic Operating VKL2301, Safety VKL2352 thermostats are used with this immersion heater – see our “Thermostats & Controls” section for more details and to purchase these products.
