Functional insufficiencies, resulting from unfavorable device combinations as well as improper control design place significant market barriers for the application of this technology. Using hardware-in-the-loop tests, functional aspects of the most common system designs are investigated and evaluated. Further dynamic system simulations on an annual basis allow an energetic evaluation and later a comparison of the different design options.

A newly developed benchmark procedure is comparing the central heat demand of the building to the maximum solar thermal gain of the solar circuit in order to calculate the maximum performance factor possible for an idealized central heating facility.

The results highlight a high optimization potential of the system control and the process layout of central heating facilities, achievable with low cost at the same time.},
