This article was interesting but those of us who are visual learners would benefit greatly from an illustration showing how these two systems work.

nice article, it's good to see something that covers the basics. It takes a lot of reading of bits and pieces in the likes of Alt.coffee to pick up this type of info.

Subject: Two Tanks
 

Intersting,  I am currently rebuilding my older Victory Arduino, it is a two group with a vertical tank.  This system has one element and a thermostat,  but two tanks. one smaller tank inside the other.   The smaller tank feeds H20  to the left and right groups.  Why the smaller tank?

Great article.  Could you let us know more about how brew temperature is regulated with a heat exchanger?  Don't they use pressurestats?  If so, why does it get to hot after sitting?
