Howdy to everybody out there is Brewtopia! First, thank you to all those who have freely posted information about all things beer and brewing on this website. It has really been a definitive resource for equipment and technique and has helped me progress as a brewer. That and theres a dacing banana available which lets you know this place is high class.
I am currently building a HERMs system, using keggles, to make the jump to AG. I am in a very similar situation as most of us DIY'ing brewers are in, in that I often have to strike a balance between cost, time, and relative difficulty to get projects completed. Here's my problem; I have (or had) an old IC that I cut done for dip tubes and was hoping to leave what was left for my HERMs coil. There is approx. 15 feet of tubing that I can work with. This is appealing for two main reasons, 1) It will keep the lowest possible profile in the keggle in order to keep the water level down and 2) It's f-ing free and reduces my waste of old parts to about 5% of the old part. Reduce, re-use, recycle, you know.
I would like to maintain the low profile to keep water level down and increase the performance of the heat exchanger. Right now, it would take 6-7 gal. to submerge the coil and that is about already a little over my goal. I wanted to do it in 5 or less. My main question is, will I get enough heat transfer to to maintain mash temps and what formula can I use to determine this?
