Product Description

Combimate 22mm


Combimate is plumbed directly on the cold water supply to the property or appliance to protect the hot water system.

As mains water flows through the Combimate, the water comes into contact with Combiphos.  The phosphate within Combiphos coats the inside of a home’s pipework, boiler heat exchanger and appliances with a non-residual, microscopic, protective coating to prevent scale-causing minerals from accumulating and aggressive soft water from corroding the system and appliances.

This limescale protection action prevents the formation of scale while retaining the health benefits of the natural minerals contained in hard water.

Unlike other limescale prevention systems (e.g. magnetic, electrolytic or electronic limescale inhibitor) Combimate is designed to ensure that all of the incoming water flowing through the unit comes into contact with the Combiphos – ensuring a consistent level of phosphate dosing is maintained.

Combimate is designed to be user-friendly; shut-off valves automatically stop the water flow when the cover is removed and the Combiphos can be refilled through a simple screw-fit cap.

Combimate provides pipe protection, appliance protection and boiler protection.
