Hi All, I have a question for you.
I am considering going the HERMS route but instead of putting the coil in the HLT just placing a small tight coil in a standard 1.7L Argos Kettle.
The kettle would be connected to the PID controlling the temperature of the water. I would think that you could coil 10mm copper piping to a diameter of 10cm with between 5-10 coils inside the kettle.
I would be doing 25-40 L batches with max 10kg of grain and 30 L of water in the mash tun.
By my rough calculations assuming no significant losses you could increase the whole mash 10 degrees C in about 15 min.
Has anyone got a setup like this? If not can anyone see any potential problems that I might have missed?
Thanks for any help in advance
Check this video. Looks like this guy built himself something similar.

I have one , cant fault it , I am no thermo dynamics doctorate holder so cant say whether its efficient but it does the job , me and Dempsey ran a test last year re the appropriate size of herms pot cant remember the link , my model is by no means asthetically pleasing on the eye ie covered in masking and red tape, but it works . The coil is double wrapped around itself inside to fit in in and get more coverage of wort flowing throw in a small space
There's a pipe bender suitable for 10mm copper up in Aldi next week. Might be of interest to you.
