In comparison with the standard systems, these systems additionally include a swimming pool component.
Using T*SOL , an indoor or outdoor pool can be integrated within the solar cycle.
In addition to calculating the solar yield for DHW supply and building heating, the influence of a solar system on the temperature of a swimming pool is calculated. The additional energy which must be generated by auxiliary heating (if the pool is to be maintained at a target temperature) is also calculated.

In addition, every system includes the following:
The swimming pool is not reheated in this system. The solar energy is first used for DHW and heating, and then the swimming pool with lowest priority. During the calculation of the solar fraction, only the energy that is supplied to the DHW and the heating is taken into account, however not that which the solar system supplies to the swimming pool.
This prevents the solar system from being parameterized so that the swimming pool is supplied with solar energy first, and the heating and DHW are not supplied at all. This would result in enormous solar coverage for the swimming pool, but no energy savings in the boiler.
