Default 20 feet too short for a chiller?

Greetings all!

I'm hoping to move to full boils soon. I have a 7.5 gallon turkey fryer. I'm hoping to build a wort chiller.

I found 20 feet of copper tubing for $19.77 at Lowe's. Is 20 feet too short? Should I wait until I can afford something longer?

Thanks!

I used 20' of copper for a CFC and last time it worked too well! Brought my wort down to 52 degrees in a matter of minutes. 20' will probably work for an immersion chiller although it will take a little longer to get it down to pitching temps, but if you plan on eventually moving to 10 gallon batches, 20' will definitely not be enough.

I started with 30' and it was fine. Of course, the ground temp at the time (Feb) was around 50 degrees.

A lot will depend upon the temp of your water.

Go ahead and start with that. You can always sweat on another 20' when you get the scratch to buy more.

Thanks for the encouragement! I think I'll go for it.

I agree with BierMuncher a lot depends on the temp of your water running through the chiller

Buy 2 lengths of tubing, make two chillers and submerge one in a bucket of ice water and another in your wort, and run water through them in series. This will chill it wicked quick.

I was going to say buy the 20 ft to tie you over for now and later if you buy a bigger chiller, you can always use the 20' section as a prechiller in a bucket of ice.

I made an immersion chiller out of 25ft of 3/8" and it'll bring 5 gallons from boil to 70 degrees in about 15 minutes Now I used an actual water hose rather than vinyl tubing. I cut a piece of hose about a inch or two long and split it in half and wrapped it around the copper and trimmed so it wouldn't overlap and slid the garden hose over that for a tight fit, and clamped. (make sense?) It does leak I tie rags around the in and out port to keep it from spraying everywhere but I can hook it to a hose and open the spigot wide open no probs, pushes alot of water through it so much that the water coming out of the chiller is only slightly warmer than the water going in.

What size is the tubing?
I was looking at Lowes a few weeks ago and the only 20 foot roll I saw for 20 bucks was the 1/4" inch tubing (and this is the Outside Diameter). Ultimately, I decided this was too small inside, but would result in a slow flow so it probably would work for a counterflow chiller. In the end, I opted for 3/8 tubing..
