Our out-dated, hard-to-control, inefficient heating system is due to be

from solid fuel), _and_ a back-boiler in the livingroom fireplace.

The back boiler concerns me - it will, of course, be disconnected from
the heating system, but I wish to be able to continue to use the
fireplace.

ISTR that the back boiler should be filled with sand, but never checked on
that.

We simply left ours in situ and continue to use the open fire.

I would advise looking at what the HSE guide lines are !
they recommend removal of back boiler rather than venting although this is an option.
having worked in the industry some 16 yrs, my safety concerns are fumes and smoke usually find their way up the redundant channels and pipes ! Stick to HSE guidlines would be my advise.
