This is a 3kw, 11inch immersed length Incoloy Immersion Heater complete with combined (operating & safety cut-out) plug-in thermostat. This product will often carry the ThermTec brand which is owned and manufactured exclusively by Heatrod Elements in Manchester. The AFSTB327 can be used in all standard domestic water areas including normal use in hard water areas susceptible to limescale. 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 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.
