I'm fairly sure the regs these days say you need a double skinned liner
all the way to the top.

I have also seen them with small boilers attached, so could do with
one of these to fit a rad in the downstairs and upstairs halls, I take
it I would need to plumb it in using an open tank system for
expansion?
Open vented more from safety than anything else, get a good fire going an
you'll be able to boil a cylinder of water in an evening... As you are
also looking at this being a backup system the thing will need to work
with gravity circulation not pumped or have any motorised valves. Gravity
means that a rad on the same floor as the boiler isn't likley to get
particulary warm let alone hot.

If you have an ordinary open vented CH system plumb it into the primary of
that via a Dunsley Neutraliser (or similar) and when you have power you
can heat your DHW and CH system saving oil. Without power you should still
have DHW and CH upstairs.

We have a sealed system here on the C/H, so I take it the neutraliser
is out.

I'm thinking of fitting just the two rads in the halls (up and down)
and using a pump for circulation, hassle would be thinking of running
pipes all the way up to the roofspace for a vent/expansion tank.

I take it a double skinned liner isnt going to be cheap :-(

About a grand. With fitting.
That sort of order,
