I want to make a HERMS coil and am looking for some advice. The idea being Id create an Immersion Chiller and rather than pull it in and out each time I need it Id attach it inside a Keggle with an input and output bored through the Keg wall and some kind of quick disconnects on the input and output. To start with Id just use this Keggle as my Brew Kettle and pump cold water to cool, but at some point in the future Id make this my HLT and use it both to control the mash temp and as a giant ice bath to cool the wort. Im a long way from the second phase, but why not plan ahead a little.
1.
Should I go with stainless steel or copper for the coil?
a.
The Big Daddy Immersion Chiller thread spells out how Id go about creating a copper one.
b.
If I went stainless steel Id use McMaster #8989k98 as suggested by Boerderij.
2.
With stainless how would I go about attaching fittings to the tubing? Copper seems straight forward as I can solder, but Im no wielder and would like to avoid wielding if possible.
3.
If I use copper should I be worried about the outside of the pipes oxidizing?
It seems like the easy choice is copper, but theres just something sexy about stainless. Im still keeping an open mind about what way to go.
