You're the spammer who was spamming the uk car maintenance group with
out of dates stuff aren't you?

| A question for the group...
It use to be commonly stated that if your frig was 10+ years old that a
newer model would be way more efficient. Is that still true? I'm asking
because my fridge is 10 years old and still looks brand new. Are the newer
ones really that much more efficient?

The newer ones currently available might have better insulation, but
the refrigeration technology itself is unchanged. This 'magnetic'
refrigerator isn't available yet. I'd stick with what you've already
got.

Age alone wouldn't tell the tale. One can still buy fridges that are
easily 10 times less efficient per cu.ft. than others. To determine if
a fridge is worth upgrading, measure its consumption with a KillaWatt
and then compare to replacement candidates here

My own fridge-freezer is about 10 years old, 22 cu.ft., and 438kWh per
year. Pretty much the same as the best of the newest ones in the same
class.

Maybe wrap it in a blanket if you want to improve the insulation, But
DON'T cover the heat-sink with the wrapping (that's the set of tubes,
usually at the back of the fridge, that get warm when the fridge runs).
If you prevent heat from being dissipated from the heat-sink, at best
you'll make the fridge work harder and use more electricity. At worst,
you'll make it break down completely.
The best fridges are the ones with a lid at the top that is opened to
access the food. When the lid is opened, the cold air in the fridge
mostly stays in it, so there isn't much waste. When the door of a
front-loading fridge is opened, the cold air just pours out onto the
floor, since cold air is denser than warm air, and the fridge then has
to cool down a whole new lot of air after the door is closed. If the
door is opened a lot, this can waste more electricity than having poor
insulation.

If I read it correctly, it doesn't explain where the heat goes TO.
It absorbs heat, and releases heat, but in order to function as a
cooling mechanism, it has to transport the heat elsewhere.
How it does that will have as much to do with its efficiency as
anything else.
