Best Double Coil Wort Chiller Tutorial - How to Build a Cheap 50 Foot Immersion Chiller 

Beautiful job. I am a Master Plumber and bought a stainless steel chiller coil. Never again. The Crafty Will Survive. Thanks.

Hey Matt, I really liked your video. I hope that you don't mind if I offer some of my experience as a few tips for your viewers, to make things easier. No criticism intended. If you haven't made anything like this before, I would use a larger inner PVC Tube for the initial former (Larger than 4" for 1/2" copper) so you can wind the helix without stress (=spilt beer, kinked pipes, shouting at the wife to leave you alone because you know what you are doing etc). Perhaps even a bit of math to approximate lengths of the intended inner and outer coils. Once you are ready to trim the tails off your handiwork, get it as pleasing to the eye as you can before you cut the copper because once you cut it, it will become your enemy. Bending springs like it when you slightly over-bend and then straighten, again to avoid, not only the spring binding to the copper tube but the empty glass on the floor being thrown out the window at the neighbours' cat and you storming off to get REALLY drunk. In all seriousness, I have one final thing for those that haven't used thread-tape before. Always wind the thread-tape onto the male thread in the same direction as the fitting you are about to screw on to it. A normal right hand thread, you turn clockwise so you wrap the thread-tape clockwise. Imagine as you turn the fitting, it is tightening the thread-tape. Cheers Matt.

Thanks for this tutorial. I just built one of these and I'm really proud of myself as I'm not really a handyman. Also happy I built a dual immersion chiller instead of a single. For those of you unsure if you should do this: do it! Two tips: 1. You don't need the hose adapters, you can just buy a hose that fits over your copper tubing and fix it with hose clamps. Just wrap some electrical tape around the copper before putting the tube over it. 2. Bend the ends over something (e.g. a small tube) to avoid kinking the copper tubing.

The wire is a good idea but you may have a more sanitary chiller if you used solder and just ran a strip of the wire down the sides of each part of the chiller soldering as you go...would take some time though.

Just great, im new to homebrew and this tutorial will make my life easier thank you great video..

I'm a kegger newbie in Australia and tried the ice bath method which was a total waste of time. I just started researching chillers and seen cheap stainless units on the Net from China but I'm wary of possible contamination and durability due to substandard materials. Your DIY double decker unit looks simple, efficent and effective. P.S. Thanks for sharing the bloopers also Matt.

So, I watched a few other tutorials before yours, and well, as a fellow perfectionist, I knew that I need not go further. Great design and execution! I'll be following your steps, and since I have my dad's complete set of copper bending springs, I expect no kinks! Thanks for a great tutorial.

was going to build this but then saw on brew international a pre built 1/2" 50 ft copper double coil IC for $80 including shipping which is how much I would have paid for supplies in this DIY. Think I'll save myself the trouble lol.

Thanks for this video. I just made one today with the help of this video, and I am more than placed of the results. Thanks!

Great video, very easy instructions and good use of items that are laying around in almost any house

Excellent Video. Just a suggestion to prevent kinking...It's a pain in the ass, but if you add water to the tubing and freeze it, before you turn your coils, the frozen water inside the tubing helps resist the stresses exerted on the copper tubing at the potential point(s) of failure (kink points) hence mitigating the risk of a major kink (or god forbid a rupture). Happy Brewing!!!!!!

Great job, man. I have used a 18 meter 0,8 cm inside 1 cm outside cooper tubing and a connector from cooper tubing to ½ inch and a male ½ inch connector (botch sides ). I used the Gardena system to connect it to the ½ connector by a 2 meter garden hose to my shower output, Then I used a small 2 meter clear hose for the outgoing water. I connected it to the 2nd end of the cooper tubing with a pipe clamp. I have put the end in my bathtub. I chilled the wort to 21*C in 15 minutes. Before I had a wort chiller I had o wait until next day that I could pitch the yeast. Thanks for the video.

Good job! This looks great. I have one that I paid for from the local homebrew shop, but I like that this one I double cool and I like that it is 1/2 inch thick.

sweet coil ! I built 2, I put one in a cooler packed with ice and water as a pre chiller, hook up the garden hose, drop the second one in the boil pot. It will take 12 gallons of 212deg wart down to 70deg in 11 mins hahaa....= crisp clean beer !

I haven't read the comments on here but if you tape off one end of your copper and fill it up with salt until its full then tape the other end it wont kink at least not as easily. then you can connect your hose and flush it out and being that you are only using it as a cooler not like a condenser for a still whatever salt stays in won't matter and it will be flushed out eventually. good video thanks for sharing!

Really great video. You're a natural in front of the camera! I'm going to need to this when I build my one-barrel system. My current coil is quite small.

We'll done vid. I think I have all I need to make mine. Thanks! I have a basic coil, full of kinks, sucks. Making a righteous coil like yours. Thanks man.

nice chiller. one of the best I've seen. top job. cheers.

Just a note, 1/2" piping is not only more expensive than 3/8", but also less efficient per unit volume being pumped through it. There is effectively less surface area on the pipe per litre being pumped through. 3/8" is easier to work with, cheaper, and will provide better cooling per litre being cycled through the system.

Matt, Thanks for posting this video. I just made mine and it turned out great!!

Beautiful work, Sir!

Sweet! Thanks man, good video

if you want to bend the copper without it kinking next time you can fill the tubing with sand and cap it before shaping/bending. I highly recommend flare fittings compared to compression fittings if you want a secure connection.

Top work there pal. I'm Going to crack on with this at the weekend. Cheers for the helpful video . Subbed 👍

Great vid! This is exactly how we're going to make our own wort chiller. I have to tell ya, though, the moment you kinked your copper tubing, I threw my hands up into the air and shouted, "Oh, FUCK!" Best Moment of Fail EVER. Followed by a nice recovery. Home brewing FTW!

Excellent. Thanks for sharing 👍

man, that looks neat! the only issue i see is the copper wire, making the chiller a little bit more difficult to clean

Looks great - I will try make this as tap water temp where I am can get a bit warm so the more surface area I can get the better. With the flattening of the tube could you have twisted the bending spring to open it up a bit? Or use an internal spring? Thanks great work.

Great work dude !!

I am from Spain where I can buy a coil of that for beer but stainless steel thanks Gracias

nice vid. thanks for putting it out there.

Did you consider using a five gallon homer bucket and cooler pump as a ice bath. Then recycle your water, you will need a waste water line to dump the ice melt in to the drain but that could be saved to another five gallon bucket. Also you don't need to but RV water hose the white kind is sanitary and not made from waste garden and industrial hoses it just a better hose overall.

Fantastic DIY video, great job buddy! I'm convinced the immersion chillers are the best solution for the small scale home brewers, and double coil one is probably the most effective I've seen so far. What's the max brew size you have used that on?

Nice work brother!

Nice work man!! This is really beautiful and looks efficient. One thing that I would like to know is have you encounter any problem cleaning the tiny gaps between the coils and wires?

one question how bad did you scratch your floors up

just some qns. The cold water goes in from the top into the inner coil, but the coolant heats up as it reaches the bottom. This hot coolant then goes into the outer coil upwards again. Doesn't it heat up the cooled wort on the top of the kettle again? I would think that you want the hot coolant to exit in the shortest route as fast as possible, rather than in the outer coil and reheating the wort.

great work thanks

You got a good price on the copper tubing, its now about $80 for 50 ft of 1/2 in OD

Great vid thankyou

After you evened out the cold water in and the hot water out with the pipe cutter what was the tool you used after that??

How did you manage to wrap the copper around the PVC pipe with such ease? I've been trying to wrap my 1/2" OD copper pipe around a 4" (100mm) PVC pipe and can't seem to do it with out it kinking. I really wanted to make an immersion chiller like this one but it's not looking good for me so far...

Man I like this design!! I am going to replicate this along with a slight modification....I am going to add a recirculating line to increase efficiency. One question, What was your IN & OUT?

You make this look so simple, but I have failed twice. My first tubing got too many kinks, and my second one simply snapped. Any tips? I am getting very frustrated.

Where'd you find a 50 ft length on copper tubing that cheap? Just checked lowes and home depot and the tubing alone is over $80

MUY BUENO!!!

Super!!! thank you!)

hey question-could you explain why yoiu want the cold to go in the inner first? It makes sense to me to have cold into the larger coils on the outside first, giving you more surface area when the water is colder. thx

When you're using your wort chiller, do you circulate cold tap water or do you pump chilled water through it? I live in Las Vegas and our tap water is about 75 degrees in the summer time so that won't do the trick for me. I was thinking about using a sump pump in a cooler full of ice water to chill my wort. What do you think?

so cool thanks....!!!

Противоточник всё равно лучше и эффективней. Кипятить в сусле не надо к тому же. Но идея хорошая, молодец.

good video

Dude that kink...i was like Noooo. Awesome work

For the part you kinked you could have used a torch to soften up the copper just a bit.

I didn't know the comic book store owner from the big bang theory made beer videos on RU-vid...

No volume

Hey, you're back! I changed my name a dew times, but I'm still BigRed. XD. Also, will you be doing any more Call of Duty?

Try the opposite... Counter Clock Wise 1rst. (C.C.W.). inside not outside... C.C.W. = Gravitational field (Test the field) ... C.W. = Magnetic field (Test the wire) having to do with Material/Physical realty... Physics... you know...just don't get stuck there, go, stretch,go inside so you can show outside. In this project, the tube is going Clock Wise. (C.W.).. for the 2 coils.... (2 x magnetic fields) Look at the coil/tube being made, looking in front of your eyes... look at the way the wire is turning. That's the deal in this... and a freaking good idea... Go Counter Clock Wise (C.C.W) inside, C.W. outside... Do C.W. x 2 and compare. :-) Fun Stuff.

can't for the life of me bend this damn copper without messing it up (inner coil). I read somewhere you can fill the pipe with salt or sand. This seems like it might work, but I haven't tried it yet.

Wanted to watch this but too hard to watch due to the dodgy background music, why do people add this?

No English sir, only practical parog sir,

copper is poisonous
