I have a friend who used to make ethanol. He ended up moving out of the country for a job, but gave me his condenser in hopes that I could use it. It's 1" over 3/4 x 48" long. If I got a dishwasher pump to recirculate the hot water through the condenser, could it function as a HERMS coil or would there not be enough surface are? If I don't have to build a huge HERMS coil or RIMS system that would be cool.
