i fell your pain bro (original poster).  i took the temp of the water coming out of my hose solidly for over 5 minutes and it "got down" to 102.

HAHA exactly. I think it would be almost pointless to get an Immersion Chiller.....

Not at all.  With a small pump you could take water from an ice bath and pump it through an immersion chiller.  With enough ice and time you could even get your wort down to lager temps.

I think it is probably OK to do it for a while, just realize it is not the best solution, and you can by all the parts at a hardware store to make an immersion chiller for about $45 or less, and it would take you 5 min. to put it together.

+1.  This is my next project so I can get my 10G lager brews down to pitching temps without having to put it in the chest freezer overnight.....

so if i wanted to cut down on my water use, i could just fill some plastic bottles with water, freeze them, sanitize them, and drop them in my wort instead of an IC?  hell, for that matter would i even need to sanitize them?  then just refreeze them when i was done?

I freeze up ten 20oz soda bottles. Sanitize with starsan right before dropping them in the wort when it hits 90*. My tap water is 88* right now so the IC does the hard part. The bottles drop 6 gallons down to less than 55* fairly quickly. That's the easy part.

It's going to be slow that way. I would sanitize them as they will be in contact with wort below 180* but it's worth a try. it's not going to be as quick as using store bought pre-sterilized ice and a partial boil but...

By the way, a friend of mine brewed his first batch (partial mash, partial boil) and we used ice to top up and chill and it went from the kettle (near 200*) to the fermenter with ice and dropped to 55* nearly instantly

It does work? I guess my math was WAY off. I don't know any other reason not to.

your math was correct if it was water at 32 degrees and not ice. ice absorbs has a specific heat that is absorbed in going from ice at 32 to water at 32.  in addition the ice is probably colder than 32.

It takes 1 calorie to raise 1 liter of water 1 degree Celsius.

It takes 80 calories to state change ice from solid to liquid form without changing its temperature at all.

It takes 1 calorie to raise 1 liter of water 1 degree Celsius.

I only wish.  That would be awesome.  It takes 1 calorie to raise 1 gram of pure water 1 degree C.
1 gram of pure water in liquid phase is 1mL in volume (at 4 degrees C)
Which means it takes 1000 calories to raise 1L (1000mL) of water 1 degree C.

1000 calories = 1 kilocalorie 
Mayhap you meant it takes 1kcal to raise 1L of water 1 degree C?

But hey, I like turtles!

Yes 1kcal.  My bad.  The 1 calorie per liter thing probably came from a bad source that confused food calories (=kcal) with real calories.  Probably Bill Nye.

In any case it takes 80 times as much energy just to state change.  So to get from 0C ice to 0C water you need to throw enough energy in to get from 0C water to 80C water.

[punatic]

I just rode my bike 12.5 miles.  The computer says I burned 290 calories (kcal ["food calories"]) doing so.  I burned enough energy during my ride to turn 402 grams of ice into steam.

Latent heat of fusion = 80cal/g
0C -> 100C = 100cal/g
Latent heat of vaporization = 542cal/g

Guess I wouldn't make too good of a steam engine would I?

But, I did see a honu (sea turtle) on my ride.

You weren't completely wrong - 1 Calorie = 1000 calories (note capitalization).  The Calorie is the unit used in nutrition. Capitalization is not always followed though, leading to confusion.

This is stupid.  We should relabel everything to say kcal instead of cal.

That would be a tonne of work!

I bet if you were amp'd up, you'd get it done.
