200 sqm – House Heating

Solar system kit designed for homes with an area of ​​approximately 100 sqm. The system will ensure domestic hot water needs and will cut the cost for house heating by 35%. Equipped with 200 vacuum tubes (8 x CS25) and a 1000L hygienic buffer tank, with two coils.

Each 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 deposited three layers of absorption that amplify the effect of solar radiation.The vacuum tube  ensures optimal absorption of solar radiation and minimum heat-loss up to the collector ramp. 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 partly cloudy sky conditions.

  • Solar collector 25 tubes – 8 pcs;
  • Hygienic buffer 1000L, S2;
  • Solar automation SR658;
