I’m correct because the door is closed nearly always. The difference in performance with the door open is barely relevant.

So I looked at link and I’m not sure this is making anyone’s point but mine. I don’t dispute that a chest freezer is more efficient, just not massively so. It looks like 15-20% more efficient for a chest vs upright, which is not shocking at all. And a fridge with it’s smaller gap to ambient will get less of a benefit. The air inside just isn’t that hard to cool and door is closed the overwhelming majority of the time.

Iirc, this is mostly a myth. The majority of the thermal mass in a fridge is the stuff in it, and the temperature of the stuff doesn’t move nearly that much from just opening the door briefly.

The reason chest fridges arent that popular is the inconvenience of having a bunch of liquid jugs and fresh food stored in a pile as opposed to on shelves.
