Default 5/8" OD Copper Counterflow Chiller

Hey everyone.

So I <heart> this CFC http://www.homebrewtalk.com/wiki/ind...r_Flow_Chiller. The problem that I am running into is that I have an immersion chiller made with 50' of 5/8"OD Copper. I was going to uncoil this copper and shove it in a rubber hose and be done with it but I cannot find rubber hose larger than 5/8" that isn't $200 for 50'.

With 5/8" OD copper I figure I would need rubber hose larger than 1 1/8" OD. Does anyone have any other suggestions or am I best to just buy a Duda plate chiller and keep my immersion chiller for those VERY hot days?

Thanks
Walt

5/8 should be the hose not the copper. Mine is 3/8 copper inside 5/8 hose. I have seen using a 6" diameter piece of pvc with the copper wound inside and the water enters and exits through the end caps.

I understand that...that's my dilemma. I already have 50' of 5/8" OD copper.

You can go big money abuse the 5/8 as the outside jacket.

And use not abuse ( smart phone typo). Get a 3/8 copper tube and use it as the wort tube. There are plenty of build plans on the site. You could just about make 2 25 footers and sell one to get some of your money back.

3/8"OD copper inside 1/2"ID copper only leaves 1/16" of space around the wort tube. Is that enough?

Your post says 5/8 not 1/2. I have a cf with a 5/8 hose and 3/8 copper tube. Mine is 25 feet and works like a champ. I actually built a second as I had extra hose and now use one with the tap water and then a post chill sump pumpin a cooler of ice as the ground water is around 85-90 degrees in northern Va.
