Everything was born in 1986 with an iconic product that will begin the story of te-sa: the first radiator valve. It is the consecration of an ambitious project that will bring the company to become a reference reality in the hydro-thermal-sanitary manufacture worldwide.

Over the years, thanks to continuous investment in the Research&Development department and machinery upgrade, our product range has increased greatly, allowing the company to achieve important goals. Among these, the development and production in 1993 of the first bar manifold, which has been a cause of great pride for us and opened up the way to the design, three years later, of the first manifold for underfloor heating systems.
