AESTB327 2¼" 3kw 11" Immersion Heater (AESTB327)

Product Code: SH311A-AA1CA1

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 AESTB327 can be used in all standard domestic water areas including normal use 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.

Diamond H WTS,  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.

This product can also be used to replace product code T11AN.

This product is designed to meet European Standards EN 60335-2-73:2003 +A1:06 + A2:09 used with EN 60335-1:2012 for the safety of electrical appliances that heat liquids for household and similar purposes. Testing has been carried out and the product approved by NEMKO – certificate available on request.
