C18ATS 3kW 18" Immersion Heater

This is a 3kW, 18 inch Copper Immersion Heater complete with operating rod thermostat (SS11) and separate safety manual reset cut-out. Installed products will carry the Shel-Nibe brand which is part of the Nibe group to which both Shel and Heatrod both belong. The C18ATS can be used in most standard domestic water areas. We would recommend our Incoloy immersion heaters for 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.

Installation Instructions for C18ATS can be found here.
