Solar system for domestic hot water equipped with 180 vacuum tubes (9 x CS20). This package has been designed to meet the needs for domestic hot water in accommodation units of up to 30 guests.
The water tank is equipped with two coils and optionally can be equipped with electrical resistance. The thermostatic valve included has the role of optimizing the consumption of domestic hot water.
Based on a specific demand, the following components will be added to the package: insulated stainless steel flexible pipes, fittings and fixing / tilting systems for solar panels.

Each tube works independently and the damage of one tube does not affect the functionality of the solar system but reduce the absorption and heating capacity.
The vacuum tubes are equipped with heat-pipes and do not contain water. The solar panels with vacuum tubes offer the highest performance of capturing the solar energy. The solar tubes are made of borosilicate glass, having chemically deposited inside three layers of absorption that amplify the effect of solar radiation. The vacuum inside the tube ensures the capture of solar radiation and its transport to the collector ramp, without thermal losses. The cylindrical shape of the tubes gives them the ability to capture optimal sun rays throughout the day, thus ensuring a good performance even in cloudy sky conditions.
