1. Notes 1.The valves and connectors are standard 15 mm plumbing fittings. 2.Reinforced plastic pipes used, as they tolerate the heat better than clear plastic pipes (which tend to collapse). 3.The pumps are inexpensive magnetically coupled washing machine pumps. 4.The heat exchanger in the HLT is made from 9,5 mm copper tubing, obtainable from suppliers of air conditioning spares and equipment.

2. Symbols Valve closed Valve open Pump off Pump on HERMS / RIMS coil in HLT My system is based on that of Mike Heydenrich, a fellow Wort Hog Brewing Club member (www.worthogbrewers.co.za). Thanks Mike! Mike uses three pumps, where I use two. There is a link to his website on the Wort Hogs website.www.worthogbrewers.co.za
