I've read some references on this board to people that have tried recirculating hot water though a heat exchanger located in their mash as opposed to the traditional method. I'm curious if anyone has actually tried this and what results they had. I'm considering trying it on my next batch, though I'm wondering what the best configuration for the heat exchanger should be. One option is the typical immersion chiller configuration which might still require stirring the center. Another alternative I was thinking was bending the tubing into a series of spikes that could be pushed down into the mash and cover a wider area.
