There are two water pumps, one from the boiler to buffer tank and one from the buffer tank to radiators. In which balance must be set up these to pumps for the good cooperation? In my system 80KW wood boiler with 3 X1000l buffer tanks, Usually the pump from the buffer to radiator pumps around 3.5 qm, but this value is much bigger from the other pump that works around 1,7 qm. If I put in the lowest setting the pump from the buffer I have very high temperature in wood boiler but my buffers are cold. ?In which technic can I set up my two pumps?

What software do you use to make these simulations?
