Answer
Thomas,

There is trapped air in the system.  You need to loosen the heater hoses and, with the engine running let the air out until coolant comes out the hoses and then tighten the clamps back up.  DO not take the hoses off.  All you need to do is let the air out by loosening the clamps and turning the heater on.
