Anyone do this? Its always a pain in the ass for me to get the chiller in the pot and lid on at the end of a boil. I always find myself pushing and trying to get it past my thermometer thermo couple. Thought having it built in already just like on the HERMs HLT would be way easier. I would use 3/8 copper for it. Any reason its not always done? Seems way simpler. Yes maybe in the way for whirlpool but so is the immersion chiller. Any thoughts and has anyone done this before?
