So I'm in the middle of upgrading from mostly extract brewing to this point, one BIAB, to an AG HERMS setup. I really enjoy building as much as brewing, plus building works because my system desires exceed my piggy bank.
Anyways, I'm halfway done on the mash tun build and I just finished the HLT / heat exchanger today, well except for needing to add the quick release male fittings. Here's so process shots:
Coiling 50' by 3/8"
All done with heat exchanger
Soldered 1/2" NPT bulkhead
View of both blukheads
All mocked up
Last, leak tested and view of adding w/ Brewmometer
Thanks for looking!!!
***Addition, I pressed in the bulkheads using the below tutorial; worked GREAT!!!***
