Just managed to pick up 18m of 1/2" annealed copper tubing on ebay for $50.
I will use it to build an immersion chiller to fit into my converted keg boiler.
Any suggestions from others who have built one?
Should i use the entire length or use 10m or so for the main coil and the rest for a smaller coil to sit in an ice bath to chill the water before entry to the main coil?
Any last minute advice would be great.
Thanks
