New Firebox Construction

Yes, you are right.
We must take one thing at the time, but at least we talked about the whole process, now its time to "tweak" the process.
I build some of this kind of systems, it is easier to expend your pw to 200kw for airco and heating, than to build a system like this, BUT
In the long run, you are way better with this system.

Your cpvc is very good to go, but go with pex, one word of warning, use the same couplers and one system.
So you will reduce the chances of leaking, and its always that coupler that is most difficult to reach....always. Angel Blush 

Your firebox and copper coils on the outside is perfect, with the ceramic insulation or cheaper and less work: vermiculite pellets, you cant go wrong, but weld a sheet over it so the moisture won't get any chance.
Pack it good full, keep 2 inch between the copper pipes, have a steady flow of 80 - 130 gallon a hour, you will be perfect.
If the water comes out with not enough heat you can always close a crane a little bit, this is easier than installing a bigger or smaller pump.
I don't think you want a sophisticated systems with sensors and such?
But the eternal match between fire, you and warming up somethings, just create a feeling for a average and leave it there.
This fire will behave different than your normal camping fire or fun fire or wood stove/place inside.

Buy two of those really cheap water temperature meters that will fit in a coupler, one for water temp in, and one for out.
A "?home heating store?" will have them in stock, i am pretty sure you know what i mean?
Make sure you have connected a 3 way valve, for if you don't have your fire running, the water will not cool off.

To have copper coils in your flue, I expect there would be some problems with it.
The smoke will cool down to much, what will give two problems alone, soot that will build up and insulate/choke your pipe (also your copper pipes) and fire hazard. You really don't want to have a fire in the flue, its worse than a 100kw pw on fire.

Cleaning the chimney.
The air draw is going to be less, due to temperature loss and the choking part.
A 15 inch pipe can clock up within 4 months, if it not catches fire!, if you use the wood stove all day and every day, if you know how to make a decent fire, without calling some indian tribes Big Grin  just saying.

Or go the extra length and make a triple walled flue.
The "outer chamber" is filled with vermiculite or ceramic blankets, the "inner chamber" would have the coil.
