I will try to draw general schema in my next posts.
Here I would like to share some thoughts which could be useful to other Replicators.
Especial successful ones.
So lets imagine we all have success with Nickel Powder + Hydrogen COP as in test 2,8 to 3.
So what - that no big deal. Lots of Heat Pumps have same. Super critical CO2 heat pump have in Summer COP up to 6.
And all this stuff become useless BUT
Lets dig deeper especially with this Nickel Powder + Hydrogen COP where it come from and what it consists of.
In successful reactor we have two heating source - coil and mysterious internal source.
With simplified math we can tell that to maintain reactor temperature at 1300 degrees we need 800 watts.
Let it be half 400 watts come from coil and second half 400 watts come from internal source. COP will be 2.
NOW lets do the trick and do EXTREMELY good thermal insulation of the reactor and now to maintain reactor temperature at 1300 degrees we need 600 watts.
If temperature is the only one requirement for internal source fuel reaction (Which is probably not, because coil is Inductor in same time and generate electromagnetic field. But lets come back to this later) than same fuel will continue to emit 400 watts and we need to feed coil only with 200 watts. COP become 3. WOW.
You get the point.
Lets imagine we Rich and can do Everything. We purchase best Insulation material from NASA. Insulated reactor with such, vacuum air, put reflecting mirrors, and do other useful and useless stuff to stop heat transfer from reactor to environment. Now our super-puper reactor needs only 401 watts to maintain 1300 degrees C.
OMG now our COP is 400. Great lets do something about it. Grab some beer and celebrate for a while. STOP we forgot about electromagnetic field. Well but heater coil is not most efficient way to generate such other ways everyone would make inductive coils with Kanthal wires and we would be able to cook some food on our stereos and TV. 
Luckily God made human and human made low resistance wires for efficient electromagnetic coils.
OKAY so we did. Now we have working reactor 1300 degrees with 1W energy consumption and 401 watt thermal power. What Next?
I tell you what next. NOW it is time to STOP wars, mine coal and oil and do other shity staff. Relax OFFCOURSE I am Joking. When we will have such source of energy we will do it for fun. 
BUT with COP of 400 even disabled one handed low IQ baboon can stitch with super glue and duct tape half working Stirling engine and LET BE THE LIGHT.
.... I should quit smoking weed at some point.....
I will share source code hopefully today. (Can work on project only in the evening)
I felt that my stupidity is almost equal to infinity.
