Why Choose the DSFI00200R?

Two independent coils: the lower coil is dedicated to the solar collector, the upper one to the backup boiler, maximising energy efficiency and solar yield. The vertical design optimises space utilisation and promotes thermal stratification, improving overall system efficiency. Pre-fitted for DHW recirculation, thermostat, temperature sensor, and electric backup heater.

Applications and Compatibility

Ideal for solar thermal systems combined with a gas boiler or heat pump backup. The wide capacity range available across the SFI/DSFI line (150 to 5,000 litres) makes this tank the ideal solution for apartments, villas, hotels, sports facilities, and industrial plants requiring a reliable and continuous supply of domestic hot water.

Standards and Certifications

The DSFI00200R complies with: PED Directive 2014/68/EU (Art. 4 Par. 3 – pressure equipment), Italian D.M. 6 April 2004 N.174 (material suitability for contact with drinking water), ErP Directive 2009/125/EC (energy-related products).
