Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.

I would check the water pump and replace would also be a good time to replace the timing belt. This is most likely the problem as the coolant will flow through the heater core with the thermostat closed, this means coolant will flow and you will feel heat before coolant flows through the radiator.
