Recirculating Mash system with electric and gas

[jyda]

Hello,

I'm thinking of creating a recirculating mash system based off a bunch of different design here. What I was hoping to accomplish was the ability for 10G batches eventually.

The problem with 10G batch is the 120V electric heaters for boiling water. Would it be possible to design one with the HLT run off electric and the BK run off gas for the 10G boil?

Are there any considerations I am missing with a system like this? Thoughts?

I've currently got my BK on Nat Gas, my RIMS is electric and the HLT is gas. At some point I'd like to go all electric but the combo works fine.

Thanks samc, I wasn't sure if there was a specific reason all the systems I seem to find were one or the other.

Classic HERMS. Control the HLT with electric, and recirc the mash through it. Then have a gas-fired kettle.

Oh, awesome. Sorry to show my noobbness

Hmm I just found http://sdcollins.home.mindspring.com/Logic.html. Seems similar to what I was thinking. Though I'm confused about the liquid-liquid heat exchange and how/why it may be separate from the HLT...

Just when I thought I was wrapping my head around it too.
