Solar thermal panels

Discoterm S

Made in Italy

Discoterm was born from a winning idea of the founder Mario Mariani, for the production of domestic hot water. A simple idea that for over 40 years has revolutionized our way of thinking to produce hot water. The Discoterm was one of the first solar thermal panels to be sold on the market, since then it has remained in production and over time has been constantly improved. In 2019, a new T&P type safety valve was introduced which is able to operate even in the presence of excess temperatures; moreover the tray receives a restyling in the new metallic gray color and in the new spaces for the hydraulic components. Discoterm S is the new solar panel of all time.
