Removing a disused back boiler from my heating circuit

[technics100]

Hi, 1st post so goo easy. here is the problem.

We live in a end terrace with 4 Bedrooms, 2 + 1 reception rooms. Its oil fired central heating. The roofspace has been converted so the 4th bedroom is 2 storeys up. I have had the chimney breast removed at roof level down to 1st floor level, so the chimney breast still remains on the ground floor, making the open fire obsolete. The problem is that the fire and back boiler are still plumbed into the heating circuit. This means I can feel the heat coming from the disused fire when the heating is on. I would like to remove this from the circuit, however I have had a look in the access panel at the side of the fire and there are 4 pipes coming from the back boiler. Do i just cut each pipe and cap it, to stop it coming into the loop? there is also a disused circulating pump in-line which I plan to remove as it isn't wired and I'm assuming just restricts the flow of water.

I would like to do this as the downstairs radiatiors never get above warm (can always keep your hand on them) although the upstairs radiators are piping hot. thermostatic valves have also been fitted to all radistors..

Any help is appreciated.

Cut and cap pipes leading into the BBU.

But those pipes are probably feeding the downstairs rads with heat.

As always I would suggest that if you dont really know what you are doing that you engage a competent plumber and if he gets it wrong then you can blame him!

Thanks for the advice, but surely it can't be that complicated. I have attached a sketch of where the pipes are going. I don't know what way they are flowing or where they lead to.

Can anyone help me work out the pipes? and see if i can cut and cap any to make the heating circuit more efficient?

Cheers
