Yeah, you’re right that there is not a national blanket ban on burning wood for heat. But there were (and still are) a lot of regulations that made gas and electric more attractive than wood for heating. There are national emissions standards for residential wood burning appliances, and in some cases state as well. In addition many localities have restrictions on wood burning and can issue temporary blanket bans based on air quality measurements. The development of this regulation went hand-in-hand with a broader cultural awareness of the importance of air quality (indoor and outdoor)—and a desire to not cut down all the nice forests around the country. So wood has suffered from a source restriction as well.
