You certainly need some form of automatic heat dump on the primary of
a solid fuel boiler so when (note: when not if) the tank starts to
boil you can dump the heat and not have to suffer the banging and
bumping from the cylinder (or a loft full of steam).

As for a special cylinder not heard that one before, always assuming
that this is a correctly installed system with gravity primary, heat
dump radiator etc.
