You might get away with having your cooling system flushed, there might be something that is plugging your heater core. A reverse flush my accomplish the same thing which you may be able to do by removing the hoses from the heater core and then using a garden hose turned on very little see if the water will come out the other side when you force the water in one side. If not there could be a problem with the heater core.
Your heater core maybe blocked. Sometimes this will happen if you use stop leak.
