Two questions: 1. My wort chiller does well getting from boiling down to about 100-90 but then takes a long time to get down to 70. I'm running tap water set to cold through my line. What do others do? 2. A lot of the wort chillers I see in magazines and online have the coils basically touching and they appear to be "bottom weighted" instead of uniformly spread out. Do they do that for shipping and then assume the user will pull the coils apart to meet their wort depth? Thanks.
