Not all. I grew up in a house that used wood as its primary means of heat (and two smoking parents but they smoked outside exclusively). These days I live in a house primarily heated by a heat pump (in a region where it does get below 0F on a normal winter), but it has a wood stove. I can't imagine a woodstove setup that doesn't leak some level of particulate to the inside. No matter what, you can tell there's wood burning inside. It is a pleasant smell (burning white/red oak), but probably not good for health. So even though I grew up with a wood stove burning all winter every winter and have one now, I seriously appreciate the heat pump as a clean and efficient means of heat for 90% of the season. To me, wood is a great emergency form of heat as we have plenty of deadfall where we live. But I would bot recommend it otherwise. And don't get me started on firewood processing...
