Are you sure you have air in coolant ? Check both heater hoses going to heater matrix are hot when engine at normal temp .

Top up coolant ,run engine till hot , keep revs up about 2000 rpm and loosen inlet pipe to matrix and bleed till coolant flowing .May be head gasket as earlier stated .Forgot to mention , take it thermostat o.k ?
