Combimate is a user-friendly domestic scale prevention device that uses Siliphos, a 100% food grade material whose use is endorsed by the World Health Organisation, (FAO/WHO ref.7 and EN1208), to prevent scale build-up and corrosion in combination boilers and other domestic hot water appliances.

When in contact with water Siliphos 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. Siliphos coats the inside of the pipe-work, 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.
