Not true! It would be accurate to say that under SOME circumstances hot water can freeze faster than cold. But as a general rule the statement is completely false.
How do I know this? I repaired commercial ice machines for fifteen years. Sometimes we had plumbers who believed that hot water freezes faster and would hook up the machine to hot water. Ice production drops by at least two thirds. The colder the incoming water the faster the ice production.
