Well, it's not like we're not used to the EPA overreaching on regulations so a production ban on the types of wood-burning stoves found in about 80 percent of the homes nationwide with stoves shouldn't be a surprise. The core of the issue is a requirement that wood stoves produce less than 12 micrograms per cubic meter of air of airborne fine-particle matter. The old standard was 15 percent.
You can still use your old wood stove - for now, and depending on region - but if you want to get a new stove, the old one will need to be scrapped out. You can't sell it to another party to recoup some of your outlay for the more efficient burner. I also suspect that the new regulations will increase the cost of the new wood-burning stoves as well though the EPA helpfully provides a list of compliant stoves.
Some areas of the country already ban outright the use of a wood stove during certain weather conditions or seasonally. Puget Sound and the Air Resources Board in that region have done that.
If you are buying a home with a wood stove, I would strongly suggest finding out if the stove is compliant. As an inspector, this isn't going to be part of my routine since there is too great a variety in the stoves themselves. Also, I would keep in mind the fact that the stove that you have may be banned from use should the local jurisdictions decide that it is necessary. Such bans almost invariably involve the traditional fireplace as well.
If you are a seller with a new wood-burning stove that is EPA compliant, I would include that information in the listing. Discuss it with your Realtor to see how best to do this.
