My friend and I were trying to install my 50' 1/2" OD SS HERMS coil from Stainless Brewing yesterday into my HLT and we ran into some problems. We are using 90 degree SS compression fittings to try and connect the coil to the couplings that I silver solder on the keg, and we realized that because of the diameter of the coil, there was no way to insert the ends of the coil into the fittings because of the curvature.
We ended up bending the "input" part of the coil a little bit which allowed use to barely insert the end of the coil into the compression fitting. Now we're able to insert the "output" part of the coil into the other 90 degree compression fitting, but in order for us to do this, we have to "push" the coil into the keg wall, so that half of the coil is very snugly jammed up against the keg wall. My question is, is there any issues with some of the HERMS coil being up against the keg wall? Most of images I see, of HERMS coils are them directly in the center of the keg without touching any of the walls. I wasn't sure if this would affect temperatures or anything. We just wanted to make sure before we put everything in place.
