Yesterday I installed a heat exchanger in my upstairs forced air unit in my house.My pump will not circulate water thru the heat exchanger.Is it possible it has air in the lines and will not let the water thru?
My pump is a grundfos and is rated to 19' head and I.m only 12 ft above the pump.I though pump should push the air out because it is mounted directly to stove.
any suggestions before I order a bigger pump?
