I am going to switch from a CFC chiller to an immersion chiller to try and improve hop flavor and aroma. However, my boil kettle has a 90 degree elbow coming out of the false bottom and comes up about 1 1/2 inches above the false bottom. This makes it impossible to simply sit the immersion chiller in the boiling wort. However, I can thread the drain tube thru the immersion chiller while the boil kettle is empty and have it sit flat on the bottom then drain the wort into the boil kettle. This means my 50 ft immersion chiller will be in the boil from start to finish of the boil. Will this hurt anything to leave it in the boil this long. All the info I can find says to drop the the chiller into boiling wort with 15-20 minutes remaining in the boil. Thanks, Jim

I am not sure I understand why you are concerned about 1.5" to the bottom of your kettle. It certainly won't bother a 50' chillers function noticably. Remember the cooled wort will fall to the bottom of the kettle. Stirring will improve its performance even more.

You might reconsider switching from a CFC to an immersion in summer when the water temperature is warmer. It could take a long time to cool.

Jim,

my opinion is that it won't hurt your beer to have the immersion chiller in it through the boil. But if it bugs you, pre-soak your IC in a weak acid solution, like star san. This will remove the surface copper oxides that would readily dissolve into your wort.

Or just put it in cock-eyed post-boil. It will work the same.

Thanks guys and Dan, I am going to recirculate ice water with a pump thru the immersion chiller. Reason for being concerned with the 1.5 inches and it being all cockeyed is that I'm doing 5 gal batches in a 15.5 gal keg and just wanted to make sure the chiller was in contact with as much wort as possible. Thanks again. Jim

One word, Jim: stir.

Bill, my plan is to recirculate the hot wort out of the kettle into a pump and back into the top of the wort just below the surface to try and create a small whirlpool effect around the chiller to shorten the cooling period. This is Jamil's method on the Mr.Malty website. Looks to be a good idea to me. Jim

I'm pretty sure the oft-quoted 15-20 minute boil time for ICs is to ensure that everything is good and steriziled. Beyond that, I haven't heard or read anything specific about why you wouldn't want the chiller in the boil for longer. People have been boiling in copper kettles for a long time.

If you 're going to recirc the wort for a whirlpool effect why not run that through your CFC at the same time? That with the IC should do a might fast chill.

Good idea, Vance, but I'm selling the CFC to justify (in my mind) the cost of a new immersion chiller and a pump from HD to pump ice water thru the immersion chiller to bring the entire thing down to lagering temps. It did bring the wort from boiling to 68 degrees in 23 minutes the first time out with no ice water run thru it. Next week I'll do a lager just to see how quickly I can get it down to lagering temps with ice water pumped thru the chiller. Thanks to all for the ideas and comments. Cheers, Jim

It's kind of a waste to pump ice water at first. I run tap water through my IC untill it's about 100-120 and then switch to recuirulating ice water through it. Takes about 15 gal of tap water to get to that temp this time of year.

Vance, I'm dropping the temp below 100 before hooking up the ice water. Jim
