The purpose of this site is to show some of the design elements of my Heat Exchange Recirculating Mash System (HERMS) for brewing beer at home. The following pages contain Recipes, Calculators, Articles, and a Brewing Log that shows the system's efficiencies. This brewing system uses elements from many different styles of HERMS and SMART breweries I have researched. The main difference with my system is that it uses Gott/Rubbermaid  coolers for the Mash Tun and the Hot Liquor Tank (HLT). I also use an hot water heater element in the HLT to maintain temperature during the recirculation of the wort and heatsticks constructed from hot water heater elements to perform all of the kettle heating duties. Also, recirculation of the wort only occurs when the temperature drops below my set point making the system an intelligently automated mash heating system.  Feel free to leave comments or suggestions  regarding the site or the system in the Feedback section.
