This is a 3kw, 15inch immersed length Incoloy Immersion Heater complete with combined (operating & safety cut-out) plug-in, high temperature range thermostat. The CESTB340 PLUS 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.
