Yesterday was my first brew day using a plate chiller. It works well, except that my ground water is about 78F. My wort was in the fermenter at about the same temperature. I tried using my old immersion chiller in a bucket of ice water as a pre-chiller, but it had almost no effect on the water entering the plate chiller.
Does anyone have a working solution for pre-chilling water? The best I can think of is gravity feeding ice water from my mash tun (10g Igloo) as my water supply and topping off the cooler as needed. I was hoping that a plate chiller would make this process less cumbersome than an IC and an ice bath, but on the first try it didn't work out that way.
