What's the difference between an electric boiler and an electrolyzer?

Backstory:

I don't understand how they create steam without hydrogen and oxygen.

I've been researching the prior art on electric boilers. This involves the type that passes the current through the water.

Here's one of many examples: Electric Boiler

There are also jet flow boilers which seem to do the same thing. I thought it might be the ac current instead of dc which allows the creation of steam without the dissociation of the water molecules. I've actually been trying to create steam this way. But this has been driving me crazy. I started experimenting with a AA. I start small. Safety first. :-) Then a AA with a disposable camera circuit. It will charge up a cap to 319 Volts. Then I jumped to 9V, 12V car battery, 120VAC, then rectified 120VAC with a bridge rectifier. So far, I've just used regular tap water. My meter reads open circuit.  I've tried a couple different electrode materials for the 12V in the 2 gallon container: plated screws, aluminum plates, spark plug. The only thing I can think of is to decrease the size of the container, dramatically. Even then, I would still have the problem of dissociation. I've been told to throw in some chemicals to decrease the resistance. But that's how to get more hydrogen production as well, from what I've read.  I would think it should go something like this:

As I increase the power, heat would rise, proportionally, till it starts becoming a vapor. As I continue to increase the amount of power, the moisture of the gas decreases as the hydrogen and oxygen content increases. That's not what happens. Production starts almost immediately, with very little heat. No steam. I'm going to try decreasing the chamber next, but I still think I'm going to be getting hydrogen and oxygen, just with a higher moisture content as the water starts to heat up.

Have you considered turning H2O as a liquid into a Fog suspended vapor
by adding mechanical energy.

Take a look and there is a lot more information information on Google
if you search ( ultrasonic fog machine ).

No killer arcs in water,  Faster then a submerged electric heater and
easy to use.

Hope this helps.

It's an old patent, and it doesn't read like a good idea.
I don't understand how they create steam without hydrogen and oxygen - do you think that this type of system wouldn't create hydrogen & oxygen?

It's a bad idea I think, which would explain why no one is using this idea to produce pressurised steam (if they ever have successfully).

Why has no one produced something that works like this since those patents were published? - because you do better with normal immersion-heating.
Getting something patented is just a level of protection on an idea, it in no way validates the idea as being of any practical value.

The only way to find out is to build them
You were asking questions around how these theoretical devices work - get building one then?

I never mentioned efficiency, and there's nothing in the patents that suggests these things would be long lasting, quite the opposite really...
(It looks potentially dangerous - be careful)

I didn't read through the whole patent but from the first few paragraphs and the images I figure it works similar to an arc furnace.

Using a gap in an electric circuit to create an electric arc which releases huge amounts of heat. Any water between the electrodes will vaporise due to the heat before it dissociates with the electricity. Any water that does dissociate will promptly burn and recombine since there is no separate storage for the gasses but there is a large spark.

Like lemonie said, it sounds like a bad idea, but I do think it could work if you get a good arc going (try a setup similar to arc welding and use de-mineralised water). Make sure the container can handle the pressure or it will blow up into a rain of metal shards, steam, boiling water and electricity.
