Ali,

I just did exactly as you described and it worked just fine here.  See 
attached image.  Please check your parameters and inputs carefully.  
Make sure you have a small timestep, and also consider adding pipes and 
the pump.  Make sure you have enough flow on the other side of the heat 
exchanger to remove the heat from the collector.  If you still cannot 
discover why it isn't working then I suggest you send your project to 
your distributor to see what they can find.
