This is a 3kw, 16inch 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.
Thermowatt RTS-3 3412173 dual function thermostats with a high temperature range can be used with this immersion heater – see our “Thermostats & Controls” section for more details and to purchase these products.
Q: I have a Range Tribune 300 litre cylinder with two Thermtec 3kw immersion heaters installed 10 years ago. One of the immersions units has failed, and I want to replace both at the same time. Is the CESTB 340 plus the right size and configuration of unit to use? DOes it come with everything I need? Is it possible that it is the thermostat that has failed and not the immersion, or are they all the same thing?
I want to order ASAP. Many thanks. Ian Durbin
