Thermostatic Shower Cartridge – Combi Boiler

The pink thermostatic cartridge uses our patented bi-metallic coil to precisely control the temperature of your shower. For use with Combi Boilers only. Built in fail safe – should one water supply become blocked, the shower shuts down. A Yellow, Green or Blue regulator should be fitted into the end of the cartridge depending on the Kw/BTU rating of the boiler.
