Combimate Limescale Prevention Device

RRP: £183.60 From £174.42


Combimate is a user-friendly domestic limescale prevention device that uses Combiphos to deliver guaranteed prevention of limescale and soft water corrosion water control, with no moving parts.  This 100% safe food-grade, tasteless and odourless natural material stops scale build-up on taps, boilers and appliances, helping to keep energy costs down and extending the life of your household water system.

Combimate is filled with the appropriate amount of Combiphos which, when in contact with water, is released in very small quantities, sufficient to keep the mineral ions in suspension.

This action prevents the formation of scale while retaining the health benefits of the natural minerals contained in hard water.  Combiphos coats the inside of the pipework, boiler heat exchanger and appliances with a non-residual, microscopic, protective coating to prevent scale-causing materials from accumulating and aggressive soft water from corroding the system and appliances.

There are two options when fitting Combimate, whole-house supply or single appliance protection.  For whole-house supply, Combimate should be plumbed in after the stop-valve on the cold water supply to the premises.  For single appliance protection, place it on the cold water supply to the specific appliance (e.g. a boiler).

Combimate is easy for any plumber or competent DIY homeowner to install and doesn’t require any electrical work or special tools.
