The thing is, it doesn't need to be said twelvety billion times. On every thread about woodburners.
And the people insisting on giving out a lecture on woodburners have absolutely no idea of the circumstances of the other posters.
There might be lots of reasons why they've chosen to use a woodburner. For example:
Maybe there's no mainline gas.
Maybe there's an existing wood burner and they can't afford to replace it (I mention this option because the scoldings about wood burners are on every single thread that mention woodburners, even if the person already has one and is asking for advice on fuel etc).
Maybe the gas supply is unreliable and they're worried about not having access to hot water/heating.
Maybe they live rurally and prefer to be self-sufficient.
Maybe they have access to free wood and simply can't afford to heat their home another way.
In other words - not everyone has options. And even those that do may have different priorities - it's not about "ignoring the science". There are ways to minimise the risks of a wood burner - such as a proper HEPA air purifier. I can't remember the stats but I believe that an air purifier combined with one of the new stoves means there is very little pollutants/particulates circulating.
And anyway, quite aside from all of the above, it doesn't need the same thing repeating. Again and again and again. As I said, it's like a bunch of vegans jumping onto every thread that asks for advice about cooking meat. Or anti-vaxxers hijacking a thread about the availability for vaccines.
I'm sure it's meant well, but sometimes you really do need to let people make their own decisions. If they can read Mumsnet, they can google.
