I thought that stirring would disturb the trub that you want to leave behind. I guess you could leave the cooled wort to stand for another 30 minutes, to let it settle before draining into the fermenter but this adds even more time.
It takes around 30 minutes for my IC to cool but this also allows the crud to settle. One thing that I have noticed is that performance of the IC is dependant on where you place it. Make sure that it is just at/below the surface or the wort or you will cool the bottom only.
I usually keep the flow fairly slow to minimise water usage and this means that the water coming out of the IC is initially extremely hot. I have only used this for cleaning to date but if you had the time for a second brew, this water would be ideal to feed back into the HLT.

Re: Using a copper coil for wort cooling
My 50L Boiler with generally 30L in it post boil takes around 30 mins with a 10M run of copper pipe with the tap on full blast.
I'm not on a water meter so don't care.
I guess its a toss up between having more copper in the heat exchanger and paying the water bill costs.

Re: Using a copper coil for wort cooling
It's probably worth stressing that we are not talking about a full-blooded stir here. Just a gentle "wafting" now and then to even out the temperature. And, yes, ideally your IC will be suspended near the top of the wort, where the cooling is needed most and where it will not disturb the trub.

Re: Using a copper coil for wort cooling
Removing the IC from the boiler will disturb the trub anyway so leaving it for 30 minutes after cooling is always a good idea.

Re: Using a copper coil for wort cooling
Leaving it for 30 minutes allows the hops to settle out and cover whatever hop filter you're using. As well as allowing any trub to settle along with the hops.
Yes, it adds 30 minutes or so to the process, but so does adding hops at flame out, and going for a 90 minute boil instead of a 60 minute boil.
I put aside 8 hours for the whole process. This is generally how long it takes me to get everything out, make the beer and then clear everything away. Pleasant sort of day, really. Especially as I usually sup a few beers while the process is going on!
