Apologies for the longish introduction. Is it not quite safe to run the
stove with a totally empty back boiler system? The metal will get hot but
will that matter? There are copper pipes leading up to the attic where,
presumably, there is an empty hot water tank. It would be a job of only a
few moments to disconnect these - there are very accessible joints just
above the stove level. Would such a system be safe to run?

I undersatnd that there are firebricks that can be used to replace the
boiler, it's not a technically difficult job, but if the rayburn is
'well embedded' this may not be an option. I have a single panel
radiator and a pump on my rayburn (vented to a header tank in the room
above), keeps the kitchen toasty.

I looked into a dunsley neutraliser, but the cost and PITA factors
were too much for what is, after all, a secondary heat source.
