[TRNSYS-users] Storage tank type 4

[Rm Chemilo via TRNSYS-users <trnsys-users@lists.onebuilding.org>]

Dear all,

I'm doing simulation for domestic water heating by using solar collector, hx, and storage tank(without auxiliary heater). Then after plotting storage tank energy balance for one year, I found heat in 874 MWh, heat out 811MWh, thermal losses 101MWh. Why the thermal losses is not qin-qout? Can anyone help me?

Thanks
