Old unused Central Heating Chimney

Hi,
I have been upgrading the insulation etc in my house over the last few years ( Double glazing, attic insulation etc.) However, the previous owners moved the Central heating to the outside of the house into an extension. The old system was based in the middle of the house and had a metal chimney going all the way to the roof for the unit.

They removed the chimney as far as the first floor and turned the boiler room into a downstairs storage room. However. The chimney is still located from the first floor out through the roof.

My intention was to have it completely removed but funds probably won't allow for this at the moment.

My question is can I fill the pipe with any form of insulation as I am sure it is just allowing cold air straight down through the house. I will eventually remove it but need ideas for a temporary fix for the winter.

The pipe is approx 10 inch diameter. There is a small door I can open in the attic, approx 5 X 4 inch to put any insulation through.

Any ideas would be appreciated. Thanks in advance,

Blake

I think the reason no-one offered any advice was that this is an unusual request - most people would just pull the pipe out and seal the stub where it passes through the roof and then either take away and make good, or weather the existing flue outlet.

Without seeing the building; -

The proposed pipe insulation needs to be in line with the existing insulation to prevent cold bridges.
Ideally the pipe should be removed, but at least seal both ends with air tight and weather proof seals.
Leaving the flue open above could allow rain in, depending on the stype of flue.
Leaving a flue full of insulation could cause problems for future owners.
What happens if they decide to use it

All advice on AAM is remote from the situation and cannot be relied upon as a defence or support - in and of itself - should legal action be taken.
Competent legal and building professionals should be asked to advise in Real Life with rights to inspect and issue reports on the matters at hand.

Thanks for the answer ONQ. I may as well bite the bullet and remove the whole thing. A roofer said he'd look up getting 4 old Roof tiles/slates to fit so I'll follow up on that, though it was over a year ago. Doing things in stages at the moment due to funds drying up but hopefully will get there. Thanks again for the various options I can consider. ((And I promise not to sue if it all goes Pear Shaped. :-D ))

The dreaded term "decommission" doesn't always mean what you think it does - the most serious of errors can be based on obsolete assumptions.
