It seems new woodburner regulations may require the complete redesign of
many existing stoves if are to be sold post 2020. See:

This seems to be as radical for these products as the mandating of
condensing boilers was for domestic gas applicances. It will be
interesting to see how the additional costs stack against the real
advantages.

It would seem to favour those manufactures who provide a "trendy" new
design each year, and severely impact those who have produced reliable
and generally well loved and proven "classic" stoves - such as Clearview.

Ironically it does not address any issues associated with open fires -
which are less efficient than even a "poor" stove.
