I'm nearly done building the frame for my new single-tier brewing rig (pics to come soon). I plan on using 3 keggles for HLT, MT and Boil Kettle with 2 March pumps to move things around from vessel to vessel. My quandry is whether to go with a HERMS or RIMS system. I really like the looks of these two:
Jeff McClain's Mossy Cup Brewing
but maybe modified to a single-tier with 2 pumps rather than gravity-based.
The one I modeled my stand after was this one:
Wort-O-Matic: Baltobrewer's Electric Stand
and I love the simplicity of the design, but I'm concerned that using the CFC as the HERMS replacement will not allow temperature changes rapidly enough to do anything but single-infusion mashes.
I'm also stuck as to whether to use gas burners under the boil and HLT, gas for the boil and electric for the HLT, electric for both...
Anyone have any compelling reasons to go with one or the other?
Thanks in advance!
