Starting from 300 l/day thermal station (Split)

97% of the solar energy is absorbed by the cylinder, and the vacuum provides ideal thermal isolation, i.e. heat loss to the outside environment is almost excluded.

During the summer day, the solar cylinder reaches up to 100°C in 15 minutes, and during idle time, the vacuum cylinders heat up to 220°C.

The cylinders do not contain water, so they are frost-resistant. Vacuum cylinders operate at -30°C. Each cylinder works independently of the other ones, so the damage of any cylinder doesn’t interfere with the work of the overall system.
