TESY EV 800L 12/9 S2 95 2SP Indirect Water Heater

The TESY EV 800L 12/9 S2 95 2SP indirect heating boiler is a high-efficiency large-capacity water storage heater designed to provide hot water supply systems for residential, commercial, and industrial buildings. The model is equipped with two heat exchangers, allowing it to connect simultaneously to multiple heat sources — for example, a heating boiler and a solar collector — thereby increasing energy efficiency and ease of use.

Advantages of the design and materials

▪️ Dual heat-exchange system – ensures fast and even water heating, even for large volumes, making it ideal for intensive residential or commercial use.

▪️ Thick new-generation thermal insulation – minimizes heat loss and keeps the water hot for a long time, reducing energy costs.

▪️ CrystalTech PRO internal coating – a premium enamel that resists corrosion and high temperatures.

▪️ Two MG+ magnesium anodes – reliably protect the inner surface of the tank against scale and corrosion, significantly extending the service life of the water heater.

Easy maintenance and flexible installation

▪️ Service opening – allows easy access to the inside of the tank for maintenance and servicing.

▪️ Optional installation of electric heating elements (TEN) of various power levels – provides flexibility and adaptability to specific user needs.

▪️ Dedicated sockets for thermostat and temperature sensors – allow precise water temperature control and optimization of the system’s performance.

The TESY EV 800L boiler is a reliable solution for ensuring a stable hot water supply in private homes, hotels, gyms, office buildings, and industrial facilities. It combines European quality, energy efficiency, and long-lasting durability while meeting the strictest thermal insulation and sanitary safety standards.
