Eitherway, I strongly recommend that you buy a cooler box, put a hole through the lid and use that as an insulated container. With long cooks, it will save you a lot of electricity.

Not really, the electricity savings are minimal:

Sous Vide Koozie - anyone tried it?

It looks nice, and neoprene is a good insulator. I’m not sure that the return on investment stacks up though. The Anova consumes 800 or 900 W when it’s heating. To keep water for the average recipe warm, I’ve seen it switch on (on average) about 20% of the time (measured by looking at my consumption meter). The actual figure will vary greatly with season and location. Let’s be ultra-pessimistic and assume that the Anova has its heater turned on 50% of the time to keep the water at the target tem…
