To accomplish this, you must be in an instance group with at least one other person. Once you're in the group, you enter any dungeon/instance and then leave your group while inside. The game will automatically hearthstone you back to your home after 60 seconds. This will also cause the 1 hour cooldown of your hearthstone to start over again.
The ghetto hearth may also be considered a sort of "cheat" or "bug" because it overrides the game mechanic of only being able to use the hearthstone once every hour.
