It implies to me a departure for a particular destination.
If you were going into another room I doubt that you'd say that you're "heading off" there, though you would be leaving your current room. It would be more common if you were "heading off to the shops" or "heading off to the airport"
I suspect this is some sort of nautical idiom, but, in any event, I would say it's perfectly acceptable. It's definitely informal though, so only to be used in an informal context.
Formal suggestions: I must take my leave ;). There are many ways to say this.
