One attempt at brewing in freezing weather convinced me to find an alternative solution to the garden hose for chilling. I throw a couple of gallons of water in a cooler along with a pile of snow (or regular ice if snow's not available), sit a sump pump in there, and recirculate the cold water through my IC.
I just put hose fittings on a couple 1/2 in lengths of tubing to hook everything up. In the winter I can chill from boiling to pitching in about 15 minutes. In the summer it takes considerably longer but still within about half an hour. Also saves a ton of water.
When I used to live in Maine I did something similar to this except I didn't have a recirculating pump I just used about 25 feet of brewing hose and one of my spare bottling buckets.
I replaced the spigot with a drilled bung and fed some brew hose through the bung and attached a valve to control the flow. I used a block of ice (available at most grocery or convenient stores) and filled with cold water let it sit for a few minutes to stabilize.
Once I was done brewing I hooked the free end of the hose to the ball valve on my brew pot and let it go by the time the wort reached the fermenter it was at 64 deg.
