Sorry, this Dufus is not at all convincing with a statement that this procedure "is supposed to" sanitize. If you could hit 130 degrees in the entire system, there is no documentation that this would work and in fact there is plenty of literature that states neither vinegar or a full 130 would be effective.
If you don't care, fine. Personally I want a system that is sanitized and free of the worst of the nasties such as Legionella. Legionella thrives in hot water but does not withstand bleach or boiling, but 130 is a long way short.
