The heater core needs to be right next to the fan that pushes the air through your ventilation system.

Is it normal for a heater core to leak?
It isn’t unusual for heat cores to develop leaks because they are often made from relatively thin metal to help aid in the heat transfer from the hot coolant inside to the air being blown over it by your vehicle’s HVAC system.
