"Smoking is old fashioned, obsolete and no longer required"
That said, if you're somewhere rural and you've got timber that needs getting rid of well then heating your home with it makes a lot of sense. Not so good in a city however.
I've owned one once, in a previous house, and it did take a bit of tinkering to work out how to use it. I mean lighting a fire seems obvious but first few times it just went out. Long story short, I discovered it makes a huge difference which way around the logs are placed in the firebox. A huge difference.
In terms of health though well slow combustion of biomass, any biomass, releases huge amounts of condensable particulates more commonly known as tar. That's what the visible portion of wood smoke mostly consists of - tar plus a bit of ash.
I wouldn't advocate banning them though. People need to keep warm somehow and given gas and electricity have been stuffed up financially in this country, I'm not going to suggest anyone be stopped from burning wood given the circumstances.
