The Happy Brewer from Great White North(eastern Ontario)
I have used this chiller when I brew outdoors, 10 gallon batches. Very easy to set up garden hose, (incorporate a flow control valve) with discharge water spilling on patio. The first seventy degrees of cooling (210 degree to 140 degree happens fast (I forgot to time it) because copper awesomeness. Cold water temperature used is 60 degrees. All temps in fahrenheit. Easy to clean and inspect. Recommended for efficiency and ease of use.
