Preliminary wild guess: It's low on coolant still in the rad/engine not just what you see in the tank.
??s Is this a right hand drive car by any chance? Do the heater hoses go to the passenger's side of the firewall where the heat is best? If so that too is indicative of low coolant or partial air in the system. Just the distance of duct from one side to the other can easily alter output temps if supply is limited,
