To cool the wort

what you used and how long it takes to cool the wort?

I use a copper wort cooler. I hook it up to my sink faucet and run it for about 25 minutes

I do partial boils - 2.5gallons - takes about 15 minutes and then dilute with water/

Ice water in sink. Wort chiller when the red fat man brings holy gifts in the cold days of darkness.

there are photos somewhere?

Ice bath, Immersion chiller, CFC, plate chillers, cold top up water. All methods. I can get it from boiling to sub 70 using a 25foot Cu IM.

I still use my sink for five gallons because I just cant spring for a immersion cooler yet. I could cool 3 gallons to pitching temp in about 15 minutes but five gallons takes nearly an hour. Fortunately it is a deep sink and most of the pot gets submerged in ice watter. When the ice watter is warm I just change out with tap watter a couple of times. If I bought ice I bet I could do it in 30 minutes or less. It's good to stir the watter around the pot and the wort in the pot every few minutes to help distribute the heat better.

i just made myself a home made chiller and it kicks ars! chilled 4 gallons in around 15 min!

I do partial boils. Before I begin brewing, I put about 3 gallons of the topoff water in the fridge, and some more in the freezer. I do about 4 sink fulls of tap water, then 1 or 2 of ice water bath, then topoff with the cold water, using the water in the freezer only in necessary.

CFC. 5.25g takes about 15 minutes (which is the time taken to drain the kettle using gravity).

I use an Immersion chiller and cool off my three gallon boils in less than fifteen minutes. Just about time to make sure everything is out of the way and fermenter and siphon equipment get a starsan treatment. Immersion chiller is very easy to make with 25' 3/8" copper tubing and a couple bucks of tubing, clamps, or whatever your set up calls for.

35' copper coil, 1 garden hose, 2 hose clamps. Coil the copper around your bottling bucket to form the coil, cut the hose and clamp 1/2 on each end of coil. This will cool 10 gallons in about 15 minutes and at a reasonable cost.
