Hi
I have modelled a simple SDHW system using type 60d with one heat exchanger and no auxilary heaters. Single speed pump, solar collector, 2 pipes, controller and tank. So far everything is working well, however I have (or it is just my displeasure)one problem: when I run the simulation the temperature within the tank doesnt change much, it doesnt response to the solar radiation and is nowhere close to the temperature leaving the collector. When the temperature leaving the collector increase the tank temp goes down.I attached the screen from the simulation. If someone know solution please help
