This is a 3kw, 15inch immersed length AESTB340 Incoloy Immersion Heater complete with combined (operating & safety cut-out) plug-in thermostat and is typically used within standard unvented domestic water cylinders. 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.
Installed products will often carry the ThermTec brand which is owned and manufactured exclusively by Heatrod Elements in Manchester. The AESTB 340 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 an equivalent product with titanium element which is the AESZB340.
This immersion heater is most commonly fitted with Diamond-H WTS, Cotherm TSE00187,
TSR00014 and Thermowatt RTS-3 dual function thermostats
