So every time I put my immersion chiller in the wort it stops the boil for about 5 mins. I know its because its cool and is sucking up that heat. Besides using my other burner, kettle, and water to pre heat it I just wanted to see what you do or if you just deal with it. Also, im going to dry hop and put oak chips in a batch for the last week of primary, do you have any experience with the chips?
