What is the optimum length to make a counter flow chiller? Or does it matter
I have
10.5 metres 10mm copper
10.5 meters qualpex 3/4"
Will I use 7 metres or the full length (or is that too long)?
I'm also soldering wire around it for turbulence.
I don't think its a matter of how long because simple put the bigger it is the quicker it will work :)
