HERMS Question

[Who is John Malt?]

I'm fabiricating a HERMS system with my old immersion chiller. In placing it in the HLT, I realized it could be a problem with direct contact with the bottom of the kettle. Will this be an issue? Anyone have experience with this?

I didn't do mine that way (against the bottom) but I don't see a problem. The wort is being pumped through there and will immediately cool right back down to the temp of the water in the HLT as it continues through the coil. Besides, the water keeps it below 212°F

Is there a difference in direction of flow?

[Danno]

Hmm, I can;t think of one.

if your using propane to heat the Kettle, at the end of the boil i spray the sides and bottom to take the heat out and help wit cooling , so no worries with the chiller touching the bottom
