    Apparently it’s worth it for commercial kitchens, and most marine cooling systems use external loops since the water is always there. In a home setting it looks like insulation is almost always more cost effective though.

      I could see that, commercial has much larger cooling demands for big walk-in freezers etc., and in marine that makes a ton of sense.
