I've been doing a lot of online searching about building a HERMS. I've noticed that just about everybody uses 1/2 or 5/8 copper coils in their HLT or HERMS tank to circulate their wort through. My question here is this: instead of circulating wort through the coil, why, why don't you circulate the hot water through a coil (say my 3/8 IC) inside the mash tun? My thought here is that it is easier to clean the outside of the coils off. If the mash temp is too high, shut down the water, and you wouldn't have wort still cooking away inside the coils in the HLT. I do realize that heat distribution in the mash would take longer to hit an equilibrium. Maybe a slow motorized mash paddle could solve this.
The reason I'm thinking about this is that I wouldn't have to build another coil for my brewery saving me a chunk of change since 1/2 and 5/8 copper are a bit pricey.
