Do I assume correctly that there is also a load flow on the DHW tank and that the problem is you need a third set of inlet / outlet ports in the tank?

If that is the case then you have two options. One is that if you have access to the TESS Thermal Storage library then you can use Type534, which allows you to define more than two pairs of inlet/outlet ports. The other is that you will need to put a flow splitter (Type11) at the load outlet of Type4 and a flow mixer (Type11 also) at the load side inlet of the tank. The load flow through the tank will be the sum of the hot water load and the energy dump flow. You will need to control the flow splitter so that the correct amount of liquid goes to the DHW load and the correct amount goes to the energy dump.

kind regards,

Hello,

I coupled the DHW tank  outputs (temperarure + flow rate) to heat source with the solar collector , and (temperature + flow rate) to load for the distribution of DHW.when the average temperature of DHW exceeds the set point  the circulation pump  transfers the excess heat of DHW tank type (4b) to the borehole ,how can i linked circulation pump with storage tank for evacuate excess energy
