Double pipe wort chiller

[takai]

Would be worse than a $30 immersion chiller. Liquid-to-Liquid thermal transfer is much more efficient than Liquid-to-Air, no matter how it works. What you could do is put a trans cooler in an external bath and recirculate through it.. but would still be worse than the $30 immersion chiller.

Where do you get a $30 immersion chiller?

I made mine and the copper pipe cost more than that.

I think that's the point.

This, with the ubiquitous 10% off voucher for masters: https://www.masters.com.au/product/900008316/hardwicks-copper-pancake-coil-1-2-12-7-x-0-91mm-x-6m

Used to be $33 so $30 with discount, seems to be up to $33 discounted now. Everyone should have hose for water supply, but if not then thats only an extra $5.

An immersion chiller made from that coil will be more effective than a trans cooler.

You should dig up the old thread that dealt with immersion chillers, rate of flow, coil construction, physics ect. There were (no pun intended) some very heated exchanges. Good value.
For me, 12m of tube with a wooden spoon in a cordless drill whirl-polling the wort works a treat. Still playing with the ideal flow rate.
