Ok, the results are in on test #1 keep in mind this was done with water, not wort. I think chillers work better in wort? I started out by testing my flow rate off my faucet.
Water temp 48F
1.4gpm open faucet
1.4gpm through chiller and about 12ft of 1/2" hose
4.6 gallons measured after chilled
This kind of surprised me, I knew my pipes where bad but wow.
From boil to....
This test was done with the cold water entering the bottom of the chiller and exiting the top. From about 150F down it was stirred most of the time. I don't know how these results stack up but for $30 including 25' of hose and fittings i'm happy.
