Test report no.: 03STO94

This solar system with combination storage tank for hot water and space heating is labeled an ITW system layout. This means that this combination storage tank and, where available, its controller have been measured and tested by the Institute for Thermodynamics and Heat Engineering (ITW) at the University of Stuttgart.

In the T*SOL mathematical model, the system parameters have been adjusted by parameter identifications such that the simulation results agree with the measurements.

The adjusted parameters in this system are therefore fixed and not changeable. In this system, this concerns the entire storage tank, the control parameters of the collector array, and the performance controller of the collector loop pump.

As a result of testing by the ITW and the subsequent validation procedure for the simulation, this system holds the status of a “tested company system.”
