I find when I shut the air off, it stops boiling in about 5 minutes.
With pump failure that would be a bit longer.
But then the heat leak rad will kick in.

I think if an unvented cylinder was threw on a fire full of water with an expansion valve fitted it would just jet out steam and water and not explode.
Think I seen a huge gas tank with a fire lit below and most of the gas vented off before it exploded.
Ive seen guys cut gas tanks in half with an angle grinder with gas still inside.

Eh?
Ryler. you are assuming that safety devices will always work.
I have seen too many incidents where a safety device failed to operate. ( seeing one incident is enough )
It should not be boiling in a sealed / unvented system
What will happen if you are not there to shut the air off. ? Can you safely drop the fire out of the stove or do you have to rely on the lack of air to extinguish the fire ( including mouldering embers )

If you want to connect your unvented cylinder to a solid fuel appliance, you need to do it via a H2 panel. A Ravi stat is not sufficient. It also needs to be installed by someone who is trained and qualified, if you care about your house insurance. Alternatively you can fit a thermal store, which will provide you with mains pressure hot water and can be fitted directly to a solid fuel appliance, provided the coils are correctly specified
The H2 panel is an overly complicated electrical device. And very expensive.
And ultimately prone to failure.
If an electrician is employed to do the install, costs will rise to about £2k.
Thats £2k versus a £150 Danfoss valve.
And the H2 is designed to link two boilers.
Mine are separate.
An RAV1 shuts off the flow with out auxillary energy being involved.
If I disabled the RAV1 on my vented cylinder and disabled the pump, I'd struggle to over heat the cylinder unless I was standing at the stove shovelling coal.
As the heat leak rad (which is about 3kw) kicks in.
