According to specific needs, the following accessories should be taken in consideration also : pre-insulated flexible pipe, connection fittings, tilting and anchoring accessories for the solar collector.
Warranty:
- 10 years for the solar collector
- 3 years for the water tank
- 2 years for the rest of the accesories
Installation:
The solar collector is mounted facing south, inclined at 45 degrees angle and in an area without shading. The connection of the collector to the lower coil of the solar boiler will be done using the flexible stainless steel pipe with elastomeric insulation.
Each vacuum tube works independently and the damage of a tube does not cause the solar system to malfunction but only to 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 inside which are chemically coated three layers of absorption that amplify the effect of solar radiation. The tube inner vacuum 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.
The boiler is positioned indoors, usually in the technical room of the building, next to the solar controller, the pumping group and the expansion vessel.
The solar system is charged with solar antifreeze liquid, air-vented and pressurized using an electric filling pump.
Once installed the system does not require annual maintenance and does not require emptying in the cold season. The recommended service interval is 5 years and involves: checking the antifreeze liquid (pressure and freezing point), checking the air pressure in the expansion vessel, checking the solar collector (fixing, visible degradation), cleaning the limestone deposited in the boiler and replacing the magnesium anode.
