In the UK people are paranoid about unvented hot water tanks. IIRC they need (expensive) annual certification inspections by a suitably qualified plumber. In France they are the norm - fed directly from the cold water main. A cheap and nasty blow off valve is fitted to vent overpressure water into an overflow. Sold in every French DIY store from about 200€. Often fitted in cheap flat conversions in the SE of England!
In France they are regularly fitted into habitable rooms without a containment enclosure - but you do not seem to hear about many shrapnel deaths!
