This is our standard 3kw, 14inch immersed length 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.

This product supersedes the CESTB340 Domestic Immersion Heater.

Installed products will often carry the ThermTec or SHEL brand which is owned and manufactured exclusively by Heatrod Elements. The 14" immersion can be used in all standard domestic water areas including normal use in hard water areas susceptible to limescale, this is an alternative to the CESTB340. If particularly aggressive water conditions are present or the duty/usage is higher than normal then we would recommend an equivalent titanium immersion such as the CESZB 340.

This immersion heater is fitted with a Diamond-H WTS dual function thermostat
See our "Thermostats" section for more details and to purchase these products.

This 14" immersion 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
