Bien souvent aujourd’hui, avec la flamb\u00e9e des prix de l’\u00e9nergie (repartis \u00e0 la baisse pour un moment), beaucoup se sont tourn\u00e9s vers des \u00e9nergies alternatives au mazout, gaz ou \u00e9lectricit\u00e9 pour chauffer leur maison. Le bon vieux feu de bois a fait un retour en force. Certes, il \u00e9met moins de gaz \u00e0 effet de serre mais est-il r\u00e9ellement plus propre ? Et bien non, car celui-ci produit ce que l’on appelle des particules fines. Vous en avez d\u00e9j\u00e0 entendu parler, ce sont les m\u00eames particules qu’\u00e9mettent les moteurs diesels. Ces particules peuvent \u00eatre filtr\u00e9es, on le fait pour des centrales au bois\/pellets ou encore sur les voitures avec des filtres \u00e0 particules.<\/p>\n

Dans nos maisons, aucun traitement, toutes ces fines particules sont rel\u00e2ch\u00e9es dans la nature. Les chiffres avanc\u00e9s sont \u00e9tonnants, le bois, c’est 10 fois moins de gaz \u00e0 effet de serre que le chauffage au fioul, mais une matin\u00e9e au coin du feu, c’est l’\u00e9quivalent en particules fines de 3500 km avec un diesel.<\/p>\n

<\/p>\n

Mais que sont r\u00e9ellement ces particules fines ? En fait, ce sont des r\u00e9sultats d’une mauvaise combustion. Dans une voiture diesel par exemple, le filtre \u00ab\u00a0retient\u00a0\u00bb toutes les fines particules et tous les x temps, celui-ci se \u00ab\u00a0nettoie\u00a0\u00bb en br\u00fblant toutes les fines particules retenues (bonjour l’odeur vous diront certains, et oui, certains FAP le font sans pr\u00e9venir 1 minute avant de rentrer dans le garage ;-)). L’essence n’a pas ce probl\u00e8me car la combustion \u00e0 l’int\u00e9rieur de celle-ci est meilleure, l’essence se trouvant sous forme gazeuse lors de la combustion alors que le diesel reste sous forme de gouttelettes, plus difficiles \u00e0 br\u00fbler enti\u00e8rement.<\/p>\n

Alors, quel choix faut-il faire pour chauffer sa maison ? Gaz \u00e0 effet de serre ou fines particules ?<\/p>\n
