Last weekend, while wishing I was at the Qld Xmas in July swap, I put together my herms. After looking at Batz' system (sorry mate, I just couldn't wait
) and reading some of the posts between Batz and Screwtop here's what I came up with:


It's a 10 lt pot with a 2200 watt element and about 3 mt of copper pipe.
The initial testing using water showed the temperature in the herms @ 67.5 and the liquid coming out of the manifold in the mash tun was 65.4, I think a 2 degree difference is pretty good from what I have read. The temp held at 65 in the mash tun for an hour and then the temp controller was adjusted to ramp the temp up to 75 for a simulated mashout, it took about 15 minutes to raise the temp.
The controller probe is in the manifold in the mash tun where the wort exits onto the grain bed.
Flow was kept at about 2 ltr a minute, hopefully that will be slow enough to prevent the grain bed from compacting.
Any Herms Gurus out there care to comment, or let me know if I could improve on the above? Oh and the above test was done before the hoses were insulated.
Cheers
Andrew
