A HERMS (Heat exchanger recirculating mash system) as many people know uses a pump and a heat exchanger to recirculate/ heat water through the mash tun. This guys inginuity has lead him to use his counter flow cooler as the heat exchanger.

Quite why we haven't seen this before I don't know.

Matt,
I've had a look all over that site and can't find any picture of him using this design. Maybe he never actually used it. Or maybe it didn't work well enough. I'm not knocking it as it looks like an ingenius device but I'm just a little surprised that he doesn't show it off on his website.
Is this something you're thinking of building into your system?

I'm planning a HERMS system but going completely different.
I've built a 3 tier gravity system out of Dexiom racking and 2x gas burners, and am in the process of converting 50l SS Kegs.
I was going to build a jacket for the mash tun, and was considering wrapping the outside of the keg in 15mm copper pipe, then injecting expanding foam between the keg/copper and external jacket (inside heavy duty plastic bags so I can unpack it if needed).
I can then run hot water from the HLT through the jacket to preheat the MT and maintain temp.
I could also us it as a fermenter and run hot/cold through the jacket as well.

I am in the process of putting together a new web page with details of my set up but, as you've asked, my heat exchanger is a 12 inch long length of 4 inch copper pipe with one end sealed by gluing a circle of copper plate to it with JB-Weld. I then wound a coil of 8mm copper and stuck it in the other end. I have fitted the sealed end with a kettle element and filled the lot with water. A thermocouple is mounted on the exit side of the 8mm tubing and is connected to a PID controller which, in turn, controls the kettle element.Vossy1 wrote:Without hi jacking the topic, I'd like to know a liitle more about your set up on this side of things Seveneer...if you don't mind that is
The exchanger isn't sealed at the top as there's no need to do so. It also allows me to top up the water before each brew session. I did consider an expansion tank but this would have been overkill
.All very simple really. This is what it looks like....
I hope this helps.
Sorry, Matt, I hope this doesn't hijack your thread
