Interesting stuff Dave. As you know, I’m trying to do most of my processing and glyc washing using no additional heat at all. So for me, it’s the drying that requires the use of the immersion. I wonder what temperature your heater will manage to put into the wet bio prior to bubbling?
I normally heat the bio and bubble until cold, but this takes two or three cycles of heating and bubbling to get it dry. Using the heater, you can maintain the temperature and hopefully do the drying in one operation (I never leave the elements switched on whilst bubbling. Safety reasons aside, I’ve found that the hot element burns holes in the air pipe as it dangles in the processor)
