It says on the box that it is made from an Alkaline Earth Silicate (AES) fiber I dont know exactly what that is  but, it has been much discussed on other forums and it is said to sinter at a lower temperature that ceramic fibre so in fact may be slightly more dangerous?

Yes I can see that having something in the centre of your living space could be a negative.
With the development of riser less stoves with powerful chimneys, you can can now have a low hight stove that can actually look very appealing and serve multiple functions like an oven a hot plate, instant radiant heat  and a mass heater.
In the past most rocket stoves had an ugly barrel and an unappealing high profile that would not be at all attractive in your lovely home.
So it might be possible to build a lovely central multi  purpose feature rather than just taking up room.

However I must point out that at least in my end of the world, modern metal box stoves are also super efficient, low wood consumption, insulated and produce very low emissions.
They are not mass heaters per.say but very attractive to look at.
Sorry I know I have deviated from your ordinal question!

As far as I know Morgan super wool is Just a trade name for ceramic fibre?
If you are in a sunny or a dark room with a torch, as soon as you handle the stuff it becomes very obvious just how much it can pollute the air space with millions of air born particles.
I cant imaging that is good for anybody but these particles are said to be body soluble meaning they wont stay in your system
although I cant imaging they are good for you in any way!
Apparently the real danger comes when the product has been heated to high temp or exposed to naked flame, at this point the fibres become ‘non body soluble’ meaning they can stay inside your body potentially causing long term issues.
Even worst is the fibres can lay dormant in your body for years and then evolve into cancer!

Personally I started using ceramic fibre 20 odd years ago but only realised the real dangers about five years ago when I was diagnosed with kidney cancer in both kidneys.
The specialists consultants are highly superstitious as there is no family cancer history and although the fibres are more commonly related to lung cancer, it appears they could attack any body organ.
I have had one kidney totally removed and only 3/4 of the other kidney left with two remaining tumours.
So yes this is something everybody should  concerned about!

No doubt a central stove with a chimney exiting dead centre would be not only very efficient but also very cool (excuse the pun)  
The required chimney pipe could just be cheap thin wall for the majority of the upper length and could be painted a nice colour.
The pipe would be hung and supported from the roof end.

The ceramic board is no doubt a very efficient material to use as a heat riser but it will become very frail and extremely dusty if disturbed  in any way!
The glue with cure rock hard and quite likely give way over time, I would suggest adding some wire around the riser as you most certainly dont want to be handling the stuff once it has been super heated!
You could possibly drop a 8” (or whatever size required) tube over the riser and back fill the voids with loose vermiculite. That would make it more secure and avoid the outsides dusting the atmosphere.  
The horizontal part of the chimney exit is not ideal but seems quite high up so should not be a big issue.
The dimensions look good, it should Roar……

Hmmm, dont know what the problem is with a 4” grinder and a wire whizzer, I must of cleaned a dozen or more.
I still managed  to pollute the air though!….

A twisted rope style wire wizzer on the end of a 4” grinder will strip a barrel in less that an hour without pouring pollution into the air.

Well done, looking forward to the first ignition…..

Hi Tom, not applicable in your case but as a point of interest …. I used two small,  powerful magnets to hold open a door on my vortex J tube. I fixed the magnet to the door and let it stick to the barrel, worked perfect for about half an hour and then the magnet ‘de magnetised’  and the door fell shut!
I am guessing the heat (about 250c) must be responsible.
Being a bit gullible, I firstly assumed the magnet was a dud and replaced it with another one for only the exact same to happen again?

Ok, well I dont know what fire wool is but if it is ceramic fibre then it is not safe to have exposed in your living space!
The problem with this type of martial is after it has been heated, it is very likely  to produce millions of air born microscopic particle into the living space, if it is disturbed  or handled in any way.
These particles are not good as they can be absorbed into your body and possibly cause serious heath issues in later life.
If you use refractory wool or mat, then make sure it is sealed inside the stove and if you ever need to disturb it, wear a mask and hoover up everything afterwards, or use a damp cloth on any susceptible surfaces.
Fibergalss rope or titanium rope is much safer as the partials are larger however the dust from any refractory material should be treated with respect.
All refractory products sold in the EU will be reasonably safe before they are heated, they become  especially   hazardous when exposed to naked flame or high heat and then exposed to fresh air.
I would not worry to much in your case but, just be aware of potential issues.
