With only 2 boards cross-EXT 2.0 have obtained spectacular results for heating the water in the swimming pool of a holiday house Brasov area. The temperature of the water in the pool was 27-28 degrees in August, 24-25 degrees in September and 21-22 degrees in October. Because the pool is located in a mountain area with lower temperatures, especially at night (in October were 12-14 degrees), 2 solar panels are insufficient. Taking into account the ability of the pool of 30 DBM, in accordance with the calculation algorithm would be needed 3-6 solar panels, ECO-EXT 2.0. I am still in process of fitting 4 solar panels, ECO-EXT 2.0 which during the spring/summer/fall will provide ground water from the pool, and during the fall/winter/primavara will provide partial incazirea space.
For hot sanitary water: according to consumption of hot sanitary water and the breakdown of consumption over a number of days is manufactured solar panels and storage capacity required.
Materials: depending on geographic location, area ratio of the number of sunny days and those with increased cloudiness, and desired temperature, we recommend 1-2 solar panels, ECO-EXT 2.0 for every 10 cubic meters of water from the pool.
Manufacturer of solar panels are transparent, unique in the world, for the production of hot water and heat for free in any of the 210 sunny days a year, statistically in Romania. With these panels can close the terraces, balconies, curtain walls, ventilated facades. Canopies can be made for swimming pools and at the same time heat the water in the pool.
