Hey Jed, I imagine a small local heater hidden directly behind or within a thermister could have a thin layer of insulation protecting it from the flowing water in the heat exchanger -- obviously the thermister has wires going to it -- a wire carrying heater power could be added -- the thermister reading could also be falsified by the external circuits that it sends its signal too -- when the stakes are great, mistakes can evolve into cunning fakes -- as you often point out, Rossi is hard to understand... something this pragmatic skeptic and that honorable believer already agree on...
