I model a system with solar collectors and underfloor heating. The problem is that the outlet temperature from the solar collectors are very low around 35 C. Also the useful energy gains are always negative which means that the energy which is received are very low, but this cannot be correct as I use the weather data from Greece. I cannot find which parameter I have to change in order to have more realistic results, if anyone has any idea it will be very useful for me. Also I attach my TPF file in order to have an overal idea of my model.

Thank you for your help.

Regards,

Eva
