I think this discussion of "boiler inspectors" may not be appropriate for commercial systems which integrate that steam turbine device, if for no other reason than that would be a self-defeating activity. I would imagine that the only way they could be successful would be to meet UL and CE standards for selling steam devices to the unwashed masses (like espresso machines).
It's not like it's a choice between risking death or not. Risk a steam explosion or risk a natural gas explosion. Or an electrical fire. Or CO poisoning. Or chimney fires. Furnaces manage large energy fluxes, and large energy fluxes have the potential to go sideways. Presumably this enterprise will only take off if the risk can be mitigated to a similar level. But if your point was "don't screw around with steam on your own", it's well taken. :) Rest assured that was never my intention.
