Faced with the growing number of problems in heating and sanitary installations (mud, limestone, corrosion,...), Mr PIERARD begins to look for a product or appliance that is really effective.
Several products have been tested by the PIERARD energy efficiency, but it was in 1989 that Gérard Pierard decided to make a mixture of several products to create the first version, in pot, of Cristalinn.
In 1996, Mr PIERARD created the Cristalinn System, in its first version: Pots and hood, in order to stand out from the filter products of the time.
