Default How to Chill in deep south

I just moved from northern Michigan to South Carolina and brewed my first SC beer on Sunday. Trying to chill wort with water the temperature of microwaved urine is not something I am used to. Just looking for suggestions from any southern brewers on how to deal with this.

I tried running the tap water through an immersion chiller that was immersed in a cooler full of ice water and then into my homemade CFC. I ended up with a carboy full of 95 F wort. Luckily I brewed a saison, so a quick soak in a tub of ice water got me down to a reasonable pitch temp of 78 F. I want to brew some lagers soon but need a more effective way to chill.

Forget the pre-chiller they don't work very well.

Use the immersion chiller and tap water to get it down to 100F or lower. Then use a cheap garden pump to recirculate ice water thru your immersion chiller. Depending on how hot it is you may run thru some ice but given some time you can get it below 50F for lagers.

This is what I do and have been having excellent results. I take it <100°F with the tap and then the rest of the way with the recirced ice water. I use 20lbs of ice to get down to ale pitching temps would probably take another 10lbs to lager temps.

I have a hard time breaking ambient temps even after half an hour of immersion chiller use. After I get to the point I just say screw it and toss it into the carboy and toss that into my swamp cooler with tons of ice to get it down into the 60s. Next brew I might try an immersion chiller recirculation pump.

HIJACK TIME

How much are the circulation pumps that you guys use for this and where did you find yours?

I thought chilling in the deep south was Mardi gras. Sorry....I had to do it.

Back on topic now.

Thanks for the fast responses. I was hoping to get by with the equipment I have, but looks like I may have to save for a pump.

You can get a cheap garden pump for under 20.00 at home depot. It doesn't need to be a fancy high dollar march pump.

What sort of GPH rating should I look for?

I use 40-50# of ice in a cooler, fill the cooler with water and then run the ice water through my immersion chiller, I top up with water until I get down below 90° then recirc the water back into the cooler, it takes me on average 20 minutes to go from flame out to 60-62° for a 5 gallon batch. my tap water is above 90° all summer and garage temps where I brew range from 105° up to 118°

The cost for my little 170GPH pond pump was like $25-30.00

I tried several pond pumps and found a good rate for my setup to be 170, the 120gph one was a bit too slow to make best use of my chiller, the 220gph was also slow to cool because the water was moving too fast to effectively transfer the heat from the wort
