I just experimented with the copper tube heat exchanger and my little HHO torch and it does produce a fair amount of heat. I got the tubes to 160 degrees in about 20-30 minutes with a 1 inch flame. and when you lightly blow through the tubes it puts heat out the back of the pipes. I like the heat exchanger. Simple yet effective!

Ramset,
 What produces poisonous gas? I've never heard anything about burning hydrogen and giving off poisonous gas. With some simple mods the system could be vented.

If you use an electrolyte  you are not using pure water

And you get poisons

Yes venting is required

@hartiberlin,  as i sad, i needed about 260 Watt for about 3 liters.
I can produce the gas with my drycell which i introduced in the "Drycell goes to Austria" thread.
I wrote there in Oktober, that the cell reaches values over faraday.

For this heater, i already cutted some copper tubes, to try it out. I will write soon about the exteriment.

@ albator 10, in the copper tube there is just steelwool, ( it should be bronzewoll but i could not find that) very pressed, and a little bit of water,i saw this in a video at youtube, and it seems, it works, you would need about 3 liters of gas /min. The more gas the better. I have two bubblers für security reasons.
You can find hundreds of videos at youtube

Certainly a good idea, to diffuse the great heat of the HHO flame with these coppertubes.
For me it does not look,as they need so much gas.
Have a look at my picture of a HHO flame and compare it. For this flame i had about 3 l/min 260Watt

This is a very impressive flame.
With 260 Watt 

Das ist echt eine dicke Flamme
Komm bitte mal nach Overunity.de
Dort ist die Heizung ebenfalls ein Thema.

The only thing I've ever read about poison being given off, is if you use water with chlorine in it. What if you use distilled water?

Does the flame put more heat out with the copper pipes than without them ?

What about putting stainless steel wool into them ?

Will this absorb the heat better and produce more heat output ?

[pmazz850]

Didn't try the steel wool. I don't think you'll really need it. Its pretty effective. With a normal size torch flame they will give off alot of heat. My torch only gives off about a one inch flame. I will try a bigger flame and post back.

This is a great thread.  What about using aluminum pipes?  Or would they melt?

@Broli and Chet, I am in too, if you want to put a collection pot together.
