HVAC Pros Ask... Question: When selecting a pump, do I include the head required to get the water to the top of the system?
Answer: Not if it's a closed loop system and the fill pressure is set to equal the elevation, plus a little extra. If the system is charged properly, the pump will need to overcome only the system resistance.
In an open system, however, if the return line comes all the way back to the tank, the pump needs only enough head to fill all the piping. Once the piping is filled and the fluid is flowing back, the pump only has to take care of the system resistance and the gap between the top of the fluid in the tank and the end of the pipe.
