Of course, I'm assuming that you have a "stupid" crockpot, one with no
thermostat. When you choose a temperature setting (warm, low or high),
it puts out a fixed amount of heat, depending on which of the three
settings you chose. If you set it to "high", and put it in your
freezer, it may not ever hit 140F. If you set it to "warm", and put it
in a home oven set to 210F, it will most likely reach boiling
temperature. But that's just a guess on my part.
You are using water for your test, which seems reasonable for a crock
pot. Water at normal pressure (sea level) cannot exceed a temperature
of 212F. If you keep putting heat into it, the water turns to steam.
Although steam can be heated beyond 212F, it won't stay in the crockpot,
and the remaining water will never get hotter than 212F. This is why
another poster cited tests using oil, which can reach a higher
temperature. The reason you need a "high" setting, is that you want to
heat the food quickly, so it doesn't stay in the range 40-140F for too
long.
Thanks for quoting that. They give lots of information. Still, as I
discussed above, the temperature of the room should have some effect on
the final temperature, assuming there is no thermostat.
