The Anova goes down to 5C but annoyingly, does not go all the way down to 0C. If it did, it would be perfect for something like chilling champagne in an ice bucket as just the impeller would run and keep the water circulating. But because the limit is 5C, you can't get just the impeller running, it would also be dumping 800W of heat into the water at the same time.
