How hot do Peltier devices get?
There are temperature limits, when operating Peltier elements. They are available with a maximum operation temperature of 200 °C, where this limit is defined by the reflow temperature of solder and sealing. Another limit is the maximum temperature between the hot and the cold side of a Peltier element.

How is the cooling efficiency of a Peltier module?
This is about what was expected. Peltier modules are only around 5% efficient. This means there was about 3% of additional losses. The following video shows taking the Peltier module from the above water dispenser and doing this Peltier cooling efficiency test.
How is a Peltier better than a compressor?
Peltiers are very, very inefficient, compared to a compressor at least. With that volume box, you need to play hard-ball with physics, to get any useful performance at sensible power. 1) Insulate the box properly.
What do you need to know about the Peltier effect?
Peltier effect cooling efficiency test. A peltier module is a solid state device often used for doing cooling. Their found in some portable coolers for carrying food to the beach or in water dispensers like the one shown below. While they’re useful for those purposes, they’re not very efficient.
Can a Peltier be heated above the solder temperature?
Peltier elements must not be heated above the temperature of the solder used to make them. Careless or inexperienced experimentation can easily bring this about. You just want to ensure (2) things: that you don’t sink too much heat off the hot side, because the heat transfer depends on the temperature difference of the two sides.
