<p>Over the course of the year usually the energy balance works out
fairly well. However, if there is a difference in the amount of
energy stored in the tank at the beginning of the simulation and
at the end of the simulation, you have to account for that in your
energy balance. Type4 has an output for this value. Also, it may
be that you are adding auxiliary energy to the tank. Type4 has a
number of modes in which it can automatically keep itself at a set
point temperatures.<br>

<div dir="auto">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?</div>
