    water heating

The solar collector system Mod. ALL BLACK allows the transfer of solar energy into a thermo-vector fluid (a water-glycol mixture) and to reduce thermal losses it is equipped with back and lateral polyurethane thermal insulation which is a high temperature resistant material and it is protected by a reflective aluminium film. The extra white glass-cover allows light rays to go over it and furthermore the glass-cover prevents from front heat loss: the glass-cover is hail resistant, this ability of a glass itself to withstand shock is improved by the process of tempering.
The galvanized steel housing frame gives rigidity to the structure and protects against atmospheric agents so it can be installed both on the roof and on the ground. The frame is painted with zinc-coated steel to prevent corrosion.
The structural double-sided tape guarantees the glass sealing on the frame, it is also used for glass window by the construction industry because it is waterproof and UV resistant. There are 4 ventilation holes in the frame which prevent from inner water condensation.
The heat transfer from the absorbing fins to the pipes takes place in a sole extrusion profile which is characterized by  a high heat removal factor. The fin surface exposed to the sun is coated with dull black paint which has a high solar  absorption coefficient and it is resistant to high temperatures and colour maintaining.

There is a complete kit to realize a solar water heating system. This kit allows to produce hot water both for the low/medium temperature heating system and the sanitary system by using solar collectors. If necessary it is possible to connect the system with a gas, pellet, biomasses or wood boiler and a thermo fireplace.
This system is very flexible and efficient, It guarantees hot water for every use in every season of the year..
