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 T11AN 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.
The T11AN employs a Thermowatt TES type dual function thermostat – see our “Thermostats & Controls” section for more details and to purchase these products.
This product has been replaced by our AESTB327 immersion heater which is a direct equivalent with a more modern thermostat and Nemko approval.
Q: We need to replace our immersion heater on our Ecodan boiler, which states its an T11/AN 3kw immersion heater, can you confirm that if I purchase the AESTB327 that this will be the correct part and will fit in the same hole?
