My personal opinion is run your supply from the boiler through the plate exchanger get rid of those tees I don't see them as necessary, and then from plate exchanger go to your furnace coil.

And based off what I read is the domestic water that supplies the plate exchanger heated before it goes through the plate exchanger?

I'm not sure what he meant by that but your dhw will always be separate from boiler water, does it currently go through your plate exchanger before it gets to your furnace coil?
No the dhw does not. But if is changed over to what your saying. Buy running the dhw through furance.
I guess my question is. Does the water treatment make a film on the metal?
If it is running now through my furance exchanger then switch it off and just use the dhw. Will that nasty stuff mess up stuff or toxic. If so then I need to just keep the boiler water running through it.

You dhw flows past the boiler supplied hot water in the plate exchanger, your domestic water absorbs heat through the plates the boiler water and domestic never mix, so let's say your water is 180 at the plate exchanger the after your domestic gets its heat from it goes to the furnace coil at maybe 160 degrees ( that temp is just a guess) but again what ever treatments you have in your boiler water never gets mixed with domestic water. Someone else will maybe help me explain it if that is not making sense.

You never use boiler water for potable water.

I understand they never mix. Your not getting what I am trying to ask.
Does the boiler water go through the furance heat exchanger?

I don't have my glasses right now but best I can tell it comes in from the wood boiler to the water to air exchanger and then to the plate exchanger for domestic and then returns to the wood boiler
