Jan 19, 2023 at 10:06 comment added Daron @Farcher Does the freezer use less electricity if the inside is already cold?
Jan 19, 2023 at 10:06 comment added Daron @Farcher Just leave the door open.
Jan 18, 2023 at 23:20 comment added Farcher @JohnDoty I take your point in that in terms of heating during the cold season(s) you are better off having a fridge in a room that you normally would heat than in a garden shed. However in the hot season(s) having the fridge in a room would not be an advantage.
Jan 18, 2023 at 23:15 comment added John Doty Sure, but if you already have a refrigerator anyway...
Jan 18, 2023 at 23:13 comment added Farcher @JohnDoty An electric heater would be cheaper to buy and maintain as there is but a marginal and transient gain in using a refrigerator. To get a "useful" efficiency gain with a refrigerator one would have to keep restocking it with "warm" items to keep getting the transient situation.
Jan 18, 2023 at 23:06 comment added John Doty Why would you be better off with an electric heater?

Jan 18, 2023 at 23:03 comment added Farcher @JohnDoty Instead of Only transiently I wrote will temporally and then there is no net gain in heat transfer efficiency. And I did not use the word efficiency as I thought it to be implied. However I have now added it. My last sentence is equivalent to your third sentence.
Jan 18, 2023 at 18:14 comment added John Doty This is nonsense. Energy is conserved. If you have 200W in, you have 200W out in the long run. Only transiently, as the device (whatever it is) is rearranging its internal energy, will the output not equal the input.
