Chill water hose ID, size DOES matter...

Yesterday I brewed my second batch at my new place/house. First time I used the hose that was on the faucet for my chill water (one of those coiled/springy type hoses) that has an ID in the 3/8" range (judging by the OD, it could be smaller though). I had my other hose attached to that, but since the first step was a smaller ID, it was restricting/reducing the flow a lot. Chill time was significantly longer than I had experienced before. This is with my larger Duda Diesel plate chiller.

Between that brew day and yesterday, I purchased a 3/4" ID hose (long enough to go from the faucet to where the plate chiller was set up). Chill time was less than half from the previous batch. Plus, I was able to get the wort to a cooler temperature than before. On the first batch I had to stop at 68F with the chiller (used a swamp cooler to get down to where I needed it before pitching the yeast). This time I got it to 64F, which I was more comfortable with (for the yeast strain used, this is a good temp). I also purchased a brass shutoff valve that goes on either the faucet or end of the hose. I placed that one the end of the hose, so that I could turn the water on/off right there (didn't need to go over to the faucet to do this :rockin:).

Of course, I pitched my yeast starter slurry into the batch last night and it was showing activity within a few hours. About 6-8 hours later, it's REALLY active (Star San foam in the airlock). :D Also, since I'm fermenting in the basement, which is in the upper 50's today (about 58 currently) the fermenting beer has actually gone down a few degrees as it's fermenting.

Moral of the story... If you're not pleased/happy with how long it takes to chill your wort down, or it's taking longer than you would expect it to with your chiller, look at the cooling water hose ID. If possible, use at least a 5/8" ID hose for your chill water source. Especially if your water source is from a faucet outside. I know some use adapters on kitchen faucets, where you're limited by other factors. Still, get the largest ID hose there that you can.

Side note: the larger ID hose is a bit tougher to coil up than the smaller ID hoses. But, IMO, it's well worth it. Faster chill times are more important than spending a few extra minutes to coil up a 50' 3/4" ID hose. :D
 
More selection on Amazon, which is where I got mine. Just look through the reviews to make sure it's one that will work for you.

BTW, with the Amazon Prime membership, shipping was free (2 day). :D
 
Greetings, @Jeff Erdmann! And welcome to the forums at Homebrew Talk :mug:

At a given source pressure, flow rate is indeed affected by the combination of inside diameter and length - something folks that dispense kegged beer deal with at a different level but conceptually the same concerns - with ID again being the dominant of the two factors.

Cheers!
 
Twelve year old thread, btw.

Both ID and length affect maximum flow rate, but I'm not sure either is a very big concern, within reason. The temperature of your tap water is probably the most significant variable.

After all, your plumbing ain't 3/4"

Ah yes, the old days when Amazon deliveries used to take more than 6 hours! :D

As far as the topic of this (old) thread: Increased water flow will speed up chilling but a slower rate will be more efficient as it gives more time for heat to transfer to the water. Also, there is a good chance that your chiller is the bottleneck for water flow. There is only so much water you can push through a single 1/4" ID copper tube. A kitchen faucet also likely has fairly narrow tubing running the cold water.

I have a JaDeD chiller that can support a fairly high water flow. I usually crank my hose wide open to start, then slow down the flow once I get below around 120F to lessen the amount of water used. It works great during the winter when my tap water is cold. It struggles to get my wort below the 90F this time of year.
