Easy Install

Manageable and innovator. Discoterm S was created by Mario Mariani as a winning idea of conceiving a compact product, easy to install and use, capable of supplying DHW from solar energy. Invented in 1975, DISCORTEM S has been progressively improved up to the current version: a solar panel with direct storage and natural circulation, a 135 litres glass porcelain tank and magnesium anode. DISCOTERM S is equipped with a T&P safety valve, active in the presence of excess temperatures. A versatile product that can be used directly, providing for the installation of a mixer upstream of the utilities or by delivering pre-mixed water to the utilities. DISCOTERM S can be used also in addition to an existing system and used in winter as a pre-heater: cold weather is not a problem and is certified to withstand temperatures down to -20 °C. An affordable investment with great results both ecological and economic terms.
