I thought I explained it in one of my other posts. Sorry!
The heat exchanger passes heat energy from one type of liquid to another without letting the 2 liquids mix. In my case, one heat exchanger passes heat from the non-toxic liquid circulating through my main diesel heater loop to the toxic engine coolant so i can preheat my engine without starting it.
The second heat exchanger is actually my on-demand hot water heater. The non-toxic fluid passes heat to potable water and is then controlled by an aquastat and thermostatic mixing valve so I have consistent and never ending hot water.
Hope that makes sense.
