Hello there...
I currently have a mean immersion chiller, but I've been thinking about a counterflow chiller for initially recurculation to bring the whole of the wort down, then going direct to the fermenter for the last few degrees..
MY big concern is whether what i propose will have enough cooling power. I reckon 2x 3m length of 15mm copper with a 22mm water jacket would cost around 65 quid in copper as i already have some brass hose connectors, but that isnt that cheap, so has anyone built one and would it be worth the money? How effective is 6m of cooling in 15mm copper? Would half the length be ok?
If you're not au fait with the style of chiller, if you google counterflow chiller, its the video which looks like a trombone.
Thanks in advance.
Rob
