Hi everyone. I am trying to understand how RIMS works. I get that its a recirculating three vessel system but I dont understand why someone would need a RIMS to heat the wort. Couldn't you just use an element to directly heat the mash tun and another element to directly heat the boil kettle? Also why does one need a HLT to transfer water to the other kettles? Couldn't you just fill the mash kettle up and reticulate through the MLT like a recirculating 1 vessel system? Trying to wrap my head around this.
