Heat exchanger coils are wound in the tank. It wasn't easy hanging over into the tank for a few hours, but it got easier as I worked my way higher in the tank. I had a 24" diameter by 30"H space to work with. The 1/2" OD refrigeration line was easy to bend, and I only had a couple spots where there was a minor dimple from bending it too tight. I used 14ga copper electric wire to space the coils & keep everything tidy.

From what I've researched with wort chillers used for brewing, it's a good idea for coils to be separated into different "zones". The first coil is laid out as a disk at the bottom of the tank. The second is a cylinder at the bottom half, then the third coil in a similar way above that. The fourth is a tighter coil in the middle from bottom to top. Currently I'm building the manifolds out of PEX and will attach it to the lines with flare fittings. With the tight space it should be a challenge!
