Random Interesting factoid
Did you know that it is a legal requirement to have a G3 qualification if you want to work on or install unvented hot water cylinders?
I think this explains why

Or the full Mythbusters video >> https://www.youtube.com/watch?v=9bU-I2ZiML0 (showing it takes an unrealistic amount of pressure to rupture the tank).

all it takes is a faulty safety - read through some of the The Health and Safety Executive (HSE) reports and investigations, I am sure there will be a few grieving families that disagree with it takes a unrealistic amount of pressure, that statement misses how pressure and temperature as well as the behaviour of superheated steam 

I am not an HSE nut but this is something to be taken seriously 

compare the energy in superheated vapour when released from a pressure vessel to TNT - I would be surprised if you were not surprised.   

The HSE aims to reduce work-related death, injury and ill health They are responsible for holding the Public Business and Government accountable

Myth Busters by comparison objective in my view is entertainment online views and revenue 

I've had my say now.

When are they used ?

I had a traditional vented cylinder but when I replaced the boiler with one that had a sealed system, the old cylinder was removed.
