@tweedledew do you actually add heat to your conderser?
If your head probe is at 160C what would “ambient” be in that general vicinity?
If you had no other heat losses (which unfortunately is not true), then that ambient to -10 chiller, set at 90C might actually get the job done.
Being able to set it to 0C doesn’t seem particularly useful, but actually having refrigeration might be.
The old standby is a bucket heater and an aquarium pump. The pump will melt if you don’t regulate the temp below 80C or so, but it will get the job done for less than $100 in parts.
