just wondering if anyone has used a radiator or automotive transmission cooler to cool wort and use a fan in front, it seems that it could cut the water bill down. Im talking a brand new radiator copper style

2 problems with that

1. 95% of all new radiators are aluminium
2. even if you can find a new copper/brass radiator the flux and solder used in them are still toxic to humans.


edit: i know this well since i work in a factory that makes said aluminium and still does an occasional copper/brass for oem

I think there is concern about the solder used in the radiators and if it has lead in it. If it is a copper radiator with lead-free solder it could probably work.

Ah I stand corrected, looks like the flux is also an issue. I'd just get some copper and make a chiller, it will generally be just as effective.

I have a buddy of mine who owns a radiator shop. He has told me a couple of stories on how bootleg distillers used to use radiators in the distilling process. Its a wonder why some of the moonshiners went crazy...

If you're thinking of running the wort through a radiator, in addition to the other concerns it seems like there would be no way to keep it from getting plugged up with debris. Plus it would be very difficult to sanitize.

Even if you find a radiator/cooler that you're sure is going to be food-safe, simply putting a fan in front of it is a terribly inefficient way to cool wort.

Not sure, but I think it would take a long time to cool wort that way. If I were looking to to cut down on water I think I would circulate ice water through my wort chiller. As a matter of fact I have been thinking about this a little bit and I think this is how I would go about it, with a immersion chiller any way. I would fill a cooler about half to 3/4 full with cold water and put a pump in it that was hooked to my chiller. When I was ready to start chilling I would turn the pump on and put the discharge line from the chiller in the sink and pump water from the cooler to through the chiller into the sink (keeping the water to clean with or what ever else you might need it for) until the bulk of the heat was gone from the wort. This way you are not only saving water but saving BTU's as well. At that point I would dump a bag of ice into the cooler, top up the water level if need and put the chiller line into the cooler so as to capture and recirculate the ice water back into the cooler. Now the cost of the ice would add to the cost of the beer but would not be that much if you made your own as apposed to buying bagged ice, maybe even freeze some 1/2 gallon milk jugs full of water. Now I know this is not exactly what you were asking about and there is more than one way to skin a cat but this is what I have ben considering to save a little water.

To answer you original question, I think it would work but it would be slow and hard to get those last few degrees to pitching temp. I also would be very leery about using and kind of radiator that was not intended for food use, no need to poison your self over making home made beer. just my $0.02 worth, well ok maybe it's more like $0.04 worth but who's counting hope this helps.

There are brazed joints at each turn. Still a no-go.
