<div dir="ltr">Dear all,<div><br></div><div>I'm using the Type 60C - storage tank and I model the heat exchanger inside the tank but when I do the connections I can not find the output for "Flow rate for heat exchanger" and I can't complete the connection with the pump (or solar collector)-if I put the flow rate from the pump I get error message "The simulation failed to converge after 5 timesteps..."</div>
<div>Does someone have idea how or what should I do?</div><div><br></div><div>Regards</div><div>Barto</div></div>
