Either the water level is too low, or the water is not circulating through the heater matrix. Your symptom was identical to that of my son's old Citroen Xsara, a system where the water always circulates through the heater from cold. On hot days the engine would overheat.

The diagnosis was the plasticky impeller of the water pump had disintegrated from its supporting flat steel blades which were just spinning uselessly in the water without circulating it much, unless the engine was revved a lot.
All is now cured and thankfully I think the cylinder head gasket has survived!
