Are there any kits yet available to build this ?

Did the company finally state some real measurements
what goes in electrical and comes out as heat ?

Many thanks.

Still looking in to this

I think these kits will become a very useful test bed for basement inventors that want to economically sidestep the danger of HHO and just experiment with low pressure hydrogen.

I have made some tests with the gas, heating a room:

roomsize: 15 Cubicm., Starttemp. 11 degree celsius
I used 14 coppertubes. Tempture was raised after 30 min at 14 degr.
total Watt used 330
For camparison, i made the same test once more with a electric heater with 450 Watt:
Starttem. 11 degree, after 30 min. Tempt. was raised to 13,5 degree.
So the gas was heating with less Watt a little bit more.
The coppertubes get quite hot, but after installing a little fan, i could touch them with bar hands.

You need to keep in mind that thermal conductivity on copper is 380 and air is only 0,025.

In your case the source of heat is burning (reaction between hydrogen and oxygen). To get most of reaction it need to be balanced  so the oxygen and hydrogen need to to be optimal for high temp burning reaction. It is important because it is source of heat/energy. You just wont get much more heat from something else.

The other part is that you need to transfer heat to environment. So you need to use thermal conduction and convection (aim flame directly into tubes), and utilize thermal radiation  just ... reflect maybe.

Also to heat up all tubes they need to be well connected to conduct well. So the are near tube tangent area need to be glued with somekind of thermal glue .. Maybe square shaped tubes.

Im sure you will get better results by fixing some things
