Po\u00eale \u00e0 bois : un peu de technique<\/h1>\n

Se chauffer au bois, ce n\u2019est pas seulement une question de confort et d\u2019esth\u00e9tique, c\u2019est aussi une affaire de rendement, de qualit\u00e9 de combustion et d\u2019impact environnemental.
Comprendre comment fonctionne un po\u00eale ou une chemin\u00e9e, conna\u00eetre les diff\u00e9rences entre convection et rayonnement, l\u2019importance du bois sec ou encore le r\u00f4le de la post-combustion, permet de mieux choisir son appareil et de l\u2019utiliser de fa\u00e7on optimale.
Cette page vous propose un tour d\u2019horizon des notions essentielles pour profiter pleinement de votre chauffage au bois, en alliant performance, confort et respect de l\u2019environnement.<\/p>\n

1. Bois sec et rendement<\/h2>\n

1 kg de bois sec produit environ 4 kWh<\/strong> de chaleur. Selon l\u2019appareil choisi, le rendement varie entre 75 et 85%<\/strong>. En valeur nette, on peut consid\u00e9rer que l\u2019\u00e9nergie r\u00e9cup\u00e9r\u00e9e sous forme de chaleur s\u2019\u00e9l\u00e8ve \u00e0 environ 3,2 kWh\/kg<\/strong> de bois br\u00fbl\u00e9. <\/p>\n

Un bois est consid\u00e9r\u00e9 comme sec<\/strong> si son humidit\u00e9 est inf\u00e9rieure \u00e0 17%. Cela n\u00e9cessite un s\u00e9chage de 2 \u00e0 3 ans. Un bois sec assure une combustion \u00e0 haute temp\u00e9rature, propre et efficace, diminuant fortement l\u2019encrassement et augmentant le rendement. \u00c0 l\u2019inverse, br\u00fbler du bois humide utilise une partie de l\u2019\u00e9nergie pour le s\u00e9chage et r\u00e9duit consid\u00e9rablement les performances.<\/p>\n

2. Diffusion de chaleur lors de la flamb\u00e9e<\/h2>\n
    \n
  • a. Chaleur de rayonnement par la vitre<\/li>\n
  • b. Chaleur de rayonnement du corps de chauffe<\/li>\n
  • c. Chaleur des fum\u00e9es<\/li>\n<\/ul>\n

    Ces diffusions ont permis de d\u00e9velopper 4 techniques :<\/p>\n

      \n
    • Convection<\/strong> : diffusion \u00ab a-b-c \u00bb, chargement 1 \u00e0 2 h.<\/li>\n
    • Accumulation<\/strong> : diffusion \u00ab a-b \u00bb imm\u00e9diate et \u00ab c \u00bb diff\u00e9r\u00e9e, chargement 3 \u00e0 6 h.<\/li>\n
    • Po\u00eales de masse<\/strong> : diffusion \u00ab a \u00bb imm\u00e9diate et \u00ab b-c \u00bb diff\u00e9r\u00e9e, chargement 10 \u00e0 12 h.<\/li>\n
    • Chaudi\u00e8res bois<\/strong> : diffusion \u00ab a-b \u00bb imm\u00e9diate et r\u00e9cup\u00e9ration \u00ab c \u00bb pour l\u2019eau chaude.<\/li>\n<\/ul>\n

      3. Proportions de chaleur<\/h2>\n

      Exemple : avec une chaudi\u00e8re (solution 4), la chaleur \u00ab c \u00bb peut repr\u00e9senter jusqu\u2019\u00e0 70%<\/strong> de l\u2019\u00e9nergie produite.<\/p>\n

      4. Corps de chauffe<\/h2>\n

      Trois familles existent :<\/p>\n

        \n
      • Acier<\/strong><\/li>\n
      • Fonte<\/strong><\/li>\n
      • Chamotte<\/strong><\/li>\n<\/ul>\n

        Le choix d\u00e9pend du mode de diffusion (1-2-3-4) et du design souhait\u00e9.<\/p>\n

        5. Convection et rayonnement<\/h2>\n

        Convection<\/strong> : diffusion par circulation d\u2019air chaud (po\u00eales \u00e0 granul\u00e9s, inserts, avec ou sans ventilateurs).
        \n Rayonnement<\/strong> : diffusion directe sur les objets (po\u00eales de masse, po\u00eales\/chemin\u00e9es \u00e0 accumulation).<\/p>\n

        Une pi\u00e8ce chauff\u00e9e par rayonnement procure un confort \u00e9quivalent \u00e0 une temp\u00e9rature 2\u00b0C inf\u00e9rieure<\/strong> \u00e0 celle d\u2019un chauffage par convection.<\/p>\n

        6. Post-combustion<\/h2>\n

        Technique qui permet de br\u00fbler les gaz contenus dans les fum\u00e9es. B\u00e9n\u00e9fices : r\u00e9duction des rejets toxiques<\/strong> et augmentation du rendement<\/strong>. Conditions : haute temp\u00e9rature + air secondaire pr\u00e9chauff\u00e9.<\/p>\n

        7. Rendement et stockage<\/h2>\n

        Un bon rendement exige une post-combustion. Une flamb\u00e9e produit souvent plus de chaleur que n\u00e9cessaire. Deux solutions pour stocker l\u2019exc\u00e9dent :<\/p>\n

          \n
        • Po\u00eale de masse<\/strong> : noyau d\u2019accumulation (argile, pierre).<\/li>\n
        • Chaudi\u00e8re bois<\/strong> : ballon d\u2019accumulation (eau).<\/li>\n<\/ul>\n

          8. Noyau d\u2019accumulation<\/h2>\n

          Un noyau efficace doit \u00eatre con\u00e7u pour \u00eatre en contact direct avec les fum\u00e9es. Exemple : le Solitherm<\/strong>, le Divino (CERA)<\/strong> ou les Brunner BSO<\/strong>. Un noyau optionnel (ex. Volare CERA) n\u2019entre pas dans la cat\u00e9gorie des vrais po\u00eales \u00e0 accumulation.<\/p>\n

          9. Pollution<\/h2>\n

          Le chauffage au bois est \u00e9cologique si les conditions sont respect\u00e9es. Seul le bois sec (<20% d\u2019humidit\u00e9)<\/strong> permet une flamb\u00e9e propre. Le bois humide emp\u00eache la post-combustion, ralentit la mont\u00e9e en temp\u00e9rature, diminue le rendement et augmente la pollution.<\/p>\n

          10. Feu continu<\/h2>\n

          Bonne pratique<\/strong> : opter pour un foyer sans cendrier et gestion \u00e9lectronique de l\u2019air primaire (red\u00e9marrage facilit\u00e9 gr\u00e2ce aux braises).
          \n Mauvaise pratique<\/strong> : charger une grosse b\u00fbche le soir et fermer l\u2019air \u2192 combustion lente, mauvais rendement, pollution excessive, encrassement. Cette pratique menace l\u2019avenir du chauffage au bois.<\/p>\n

          11. Puissance nominale<\/h2>\n

          La puissance nominale est celle o\u00f9 le rendement est optimal. Exemple : rendement 80% = 1 kg de bois \u2192 3,2 kWh. Si la puissance nominale est de 6 kW, il faut \u2248 2 kg de bois\/heure<\/strong>. Pour les po\u00eales de masse\/accumulation, suivre les recommandations fabricant. R\u00e8gle : 80 kg de masse par kg de bois<\/strong> charg\u00e9.<\/p>\n

          12. Normes europ\u00e9ennes<\/h2>\n
            \n
          • EN13229 & EN13240<\/strong> : po\u00eales \u00e0 convection et accumulation, test\u00e9s sur 20 min \u00e0 puissance nominale.<\/li>\n
          • EN15250<\/strong> : po\u00eales de masse, test\u00e9s en conditions r\u00e9elles avec obligation de diffuser \u2265 1,2 kW\/h pendant \u2265 8h.<\/li>\n<\/ul>\n

            13. Gestion \u00e9lectronique du feu<\/h2>\n

            La r\u00e9gulation de l\u2019air primaire optimise le rendement. Exemples :<\/p>\n

              \n
            • Brunner EAS<\/strong> : id\u00e9al pour po\u00eales de masse (fermeture automatique air + conduit apr\u00e8s extinction).<\/li>\n
            • CERA IQ Matic<\/strong><\/li>\n
            • Jid\u00e9 RT2012<\/strong> : r\u00e9gulation selon temp\u00e9rature pi\u00e8ce.<\/li>\n<\/ul>\n

              14. Cr\u00e9dit d\u2019imp\u00f4t<\/h2>\n

              En France, tous nos appareils sont \u00e9ligibles au Cr\u00e9dit d\u2019Imp\u00f4t<\/strong> sauf chemin\u00e9es ouvertes et gaz. Conditions (Ademe) :<\/p>\n

                \n
              • Rendement \u2265 70%<\/li>\n
              • CO moyen \u2264 0,3%<\/li>\n
              • Indice performance environnementale \u2264 1<\/li>\n
              • \u00c9missions de particules \u2264 90 mg\/Nm3<\/li>\n<\/ul>\n

                Le label Flamme Verte<\/strong> n\u2019est pas obligatoire : il s\u2019agit d\u2019un classement des fabricants. Le label \u00ab 6 \u00e9toiles \u00bb signifie simplement conformit\u00e9 aux normes exig\u00e9es par l\u2019Ademe.<\/p>\n
