Look at the solar collector example in the example file folder. (SolarCollectorFlatPlateWater.idf)
The example shows you how to connect the solar collector to a tank. An electric heater is to heat the water, when there is not sun. The heater is in a tank (instantaneous).
If you use one of the DHW branch as a heating coil branch for a third tank, this tank will be heated to a temperature lower than the main tank. Use this tank to feed the radiant panel.

Hello
OK I understand your point, but how can we use two tanks and one group of solar colectores how could the controlstratagy be set up?
Thank´s for the answer.
