Replace the heater water valve infront of the firewall and check that there is a vacuum from the manifold to open the valve.  My valve was corroded and stick closed and the rubber hose had a crack so it was loosing vacuum.  Heater flapper in mine is a bit lazy and I hear a clunk a minute or so after I make a change.  Another job for another time.  🙂
