Hacked a electric 40g AO Smith water heater. My phenumatic saber saw made short order of this strip 8" wide out of jacket of tank. Ran a sharped putty knife in saw slot, and peeled the metal 22g jacket off, then finished off with a 5in1 painters tool to strip polyiso foam insulation. Drilled a chase hole from the top thru the foam fill hole. Cleaned up the hole with a 5/8" threaded rod file. Rolled 1/16" aluminum transfer plates and aluminum taped them in place. ( Nashua Aluminum tape is amazing stuff, clean all surfaces with Alcohol) Rolling rig worked well this is 50' of 1/4" line. With room to spare for another 50'. but wonder if I will need it.
