Project Summary

Description
The existing heating plant was already preset for solar thermal.
The coincidence between maximum heat demand and solar energy availability in the summer makes the system very convenient.
The target building’s conditions are very good and the rooms offer a high level of comfort.
The solar systems provides heat for domestic hot water preparation. Flat plate collectors have been chosen.
