This is a 3kw, 11inch Incoloy Immersion Heater complete with separate operating & safety cut-out rod / stem thermostats. Typically used within smaller thermal store cylinders. This product will often carry the ThermTec brand which is owned and manufactured exclusively by Heatrod Elements.

The ADATB327 / ADHTB327 LWD is specifically designed with low watts density aimed at use in heavier duty applications such as thermal stores and in hard water areas susceptible to limescale. The element is bonded to the brass flange with an environmentally friendly, WRAS approved, epoxy bond, making for more robust hydraulic and corrosion proof performance.

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.

A high temperature range Diamond H WTS thermostat is used with this immersion heater – see our “Thermostats & Controls” section for more details and to purchase these products.
