Wood heaters are estimated to be responsible for more pollution-related deaths than all the cars on our roads. This national map shows which areas are affected the most.
As someone who grew up with wood heaters, I have to disagree with some of that. You are right that you need space to store wood, but maintenance is generally straightforward for many models of wood heater. “Costly” depends on your reference point - as the article mentions, cost of living and energy prices are likely pushing more people to use them, and if you live in a semi-rural or regional area, then you will often have a cheap supply of wood to burn.
It does take a little bit of practice to learn how to control the heat output, but most of this is understanding two things: 1) the lag between the firebox temperature and how rapidly it is burning wood, and 2) how different types of timber burn (lightweight timbers such as pine burn quickly, denser timbers like ironbark and redgum take longer).
The problem, as the article points out, is that one controls the fire (and hence heat output) by reducing the oxygen intake - which leads to incomplete combustion and a lot more particulates and pollutants in the air. Newer designs allow for more efficient combustion but still suffer the same basic problem.
