You're probably not still having the issue, but if you have this problem, try burping the water pump. Loosen the heater hose going off the top nipple until you can almost pull it off, then let it vent air until the coolant hits it. You can get a pocket of coolant in the top of the pump/the bend of the heater hose and not get any flow of coolant to the heater.
