There are several anagrams to be found in the name - "Mash", "a sip"
and "mdh" (my initials). I also like the reference to "mad" unorthodoxy
in brewing - It's fun to be adventurous!
The hot-side is entirely made of polyethylene vessels: a 120-liter hot liquor tank, a 50-liter mash tun and a 100-liter kettle. I use a geyser element and thermostat to control the temperature of the hot liquor tank, and an Incoloy 3kW electrical element for the kettle.
The system is single-tier, and uses three magnetically-coupled washing machine pumps (one per vessel) to move fluid between vessels. The picture below shows one of these pumps, that cost just R150 each ($20). On the far left is the switch box for the pumps, and on the right, behind the wooden manifold mounting, is a quick-connect for cooling water for the counterflow chiller. The copper tube that takes the wort to the chiller is visible bottom-right.
