Looks good... Water flow direction also looks good. You could change it between the first two batches to see if one cools better than the other.
I would HIGHLY recommend making sure the water lines are outside the kettle, and on a down angle, so they drip outside the kettle, not into it. Otherwise, follow best practices when using the IC...
I made my first IC out of 20' of 3/8" copper. Cooled 5.25 gallons of wort from a boil to ~65F in about 12-15 minutes. 50' of 3/8" did it in about half that. Move the chiller inside the wort/kettle and you'll get faster cooling times.
I eventually changed over to a plate chiller. I used that for the first time for the batch that was brewed on 6/12. Can't wait to brew it again and use it.. :rockin: Much less physical work there, you just watch the thermometer in it and adjust the valves accordingly. From kettle, through chiller, into fermenter. All with the lid on the kettle.
