This chapter covers all parts of the existing demonstrator which convert an energy form outside the system border into water at a higher temperature level.
65NT_U25H1
The thermal solar system provides energy for the domestic hot water boiler and, if there is excess energy, high temperature for the high temperature grid.
65NT_U30P4
The solar thermal collector built of vacuum tubes and is mounted to the outer wall of the SFW Unit.
