rob been looking at hotboxes and even though they state up to 150c i'm sure at max flow the water won't be as hot as they say , so are the hotboxes you posted links for yesterday adequate. also whats the difference with a hotbox and a dry steam setup.
I have a honda gx 190 5.5 hp which i think is 3.2 kw does this sound about right .
A hot box will only produce about 85c .
Wet steam is 100c and dry steam is wet steam that has been heated again till there are no water droplets left.
To keep dry steam dry you will need specially insulated hose and fittings because as the steam cools along it's journey ,it will recondense and become wet steam,cool it again it will become hot water etc.
If you can see the steam it's wet steam or hot water.
Machines like the Falch (the video Lee posted) are capable of producing steam ...you will never achieve this from a hotbox . Although two hotboxes in series is will get there. First hotbox will get to 80 c plus then the next one will get you up around boiling depending on heat loss.
Your machine connected to a 15lpm hot box (21lpm would give better results) will do the job . It might be slower but possible.
Watch out for anything metal ,fitting s,lance etc as the become a bit unpredictable at higher temperatures ! Things that didn't leak might start to due to expansion.
