If anyone in the Philly area is interested in scaling up to a 10 gallon MoreBeer tippy dump system, I'm selling mine.

The system uses a HERMS coil, pump and two ranco controllers to automatically regulate the mash temperature. Once you set it, you can go about doing other chores while the mash maintains its own temp. Includes all hosing, fittings, the sparge ring, false bottom, etc. I'll even throw in my mash paddle and a hop spider. Kettles are 15 gal.
Would like to see it go to a good home.
