Indoor air pollution from New Zealand’s 523,000 wood burners was estimated to account for 446 hospital admissions for heart and lung problems, and 101 early deaths annually, in a country with a population of just over 5 million people. Breathing fumes from gas cooking indoors created more than 1,000 hospital admissions, 208 early deaths and more than 3,000 new cases of childhood asthma each year.
Weirdly enough, a modern wood burner is a lot better than a gas stove. I guess because the fumes are immediately vented outside?
