| hi Like your case also I have simulated one model, but have't specified any boiler avilability schedule for boiler. I guess that E+ engine run automatically boiler imediately outdoor air temperature fall below 5C, while above 5C heat pump water heater is availble. In my model case have used water heater mixed boiler (Water heater and thermal storage) with heater fuel type electricity, and from output variables see that it work corectly when outdoor temperature is below 5 C. I dont know how you have modeled in your case, have you used simple boiler at plant heating and cooling equipment ? or have also modeled like my model case. If you have modeled with simple boiler, I would like to know how you have modelled (branch connections) if is possible, just to learn how you have modeled !
