Temp should be warm... Not Hot...
Around 40-45C should be fine
Just run the Hot tap for the heat baths and that's adequate.
Over heating causes undesirable consequences and will drag out more oils and yellowing agents...even the 'Dreaded Jello Blobs'
Note: You can do the extraction using just cold water throughout...this will give nice white Xtals but at cost of a little bit of yield.
The purpose of heating is to 'Drag out All of the available product inc. extra stuff that can be cleaned up later if wanted'.
(Although cleaning is not really necessary as you are going to Vaporise it anyway)
