Ok I'm a slightly confused about your post Daox. Just to restate to make sure I understand:
In 15 minutes I should see a jump in temp, but 30 won't really get me very far?

I read about someone else's who had one on their insight and they said that it never got above 60*. My gauge actually only starts at 100* and I don't have a thermometer to check the starting temp. There is probably room to move it down, but if I don't need to then I won't bother with it. It gets to 100* faster, but I can't see the starting point.

Do you (or anyone else) have a rough number as to how much room above it should have? I went out and measured.
