too much anti freeze has nothing to do with heater. but you should always keep the antifreeze level under the MAX indicator on the reservoir because you need the space for the heated antifreeze to expand and to siphoned back when it's cooled down.
There are a bunch of things that can cause that. Water pump, thermostat, switch not engaging the heater, air in the heater core, not enough antifreeze in the cooling system. do i need a new thermostat

If there is a leak in the rubber tubes that flow into the heater core, or if the heatercore is damaged, you will smell the antifreeze in the cab of the vehicle. You may need new hoses to the heater core and/or a new heater core.

Your car shouldn't "burn" antifreeze. If it actually is "burning" antifreeze then chances are you have a blown/leaking head gasket or possibly a cracked engine block which allows antifreeze to enter the combustion chambers. If your antifreeze is just disappearing then it is probably leaking out from somewhere. Possible leak areas to check out would be the radiator hoses, heater hoses, radiator, water pump, and the heater core. Most of the time if the heater core is leaking you'll be able to smell the antifreeze inside the car while the engine is running and the heater is on.
