D\u00e9couvrez comment r\u00e9duire la consommation d\u2019\u00e9nergie li\u00e9e \u00e0 l\u2019eau chaude sanitaire et am\u00e9liorer votre score PEB.<\/p>\n

\u00a0<\/p>\n

Pourquoi s\u2019int\u00e9resser \u00e0 l\u2019eau chaude sanitaire ?<\/p>\n

L\u2019eau chaude sanitaire (ECS) repr\u00e9sente 15 \u00e0 25 % de la consommation d\u2019\u00e9nergie d\u2019un logement.<\/p>\n

Optimiser ce poste est essentiel pour am\u00e9liorer la performance \u00e9nerg\u00e9tique globale.<\/p>\n

Types de syst\u00e8mes ECS<\/p>\n

– **Chaudi\u00e8re combin\u00e9e** : produit le chauffage et l\u2019eau chaude ; bon rendement mais d\u00e9pend du chauffage.<\/p>\n

– **Boiler \u00e9lectrique** : simple mais \u00e9nergivore ; \u00e0 \u00e9viter sauf usage ponctuel.<\/p>\n

– **Chauffe-eau solaire** : jusqu\u2019\u00e0 60 % d\u2019\u00e9conomie sur la production d\u2019eau chaude.<\/p>\n

– **Pompe \u00e0 chaleur pour ECS** : rendement (COP) de 2 \u00e0 4 selon la temp\u00e9rature d\u2019air.<\/p>\n

Bonnes pratiques<\/p>\n

– Isoler les conduites et le ballon de stockage ;<\/p>\n

– Installer un mitigeur thermostatique ;<\/p>\n

– Abaisser la temp\u00e9rature du boiler \u00e0 55\u00b0C (limite bact\u00e9ries) ;<\/p>\n

– \u00c9viter les pertes d\u2019eau chaude dans les canalisations trop longues.<\/p>\n

Impact sur le certificat PEB<\/p>\n

Un syst\u00e8me solaire ou thermodynamique am\u00e9liore la note du b\u00e2timent et peut faire gagner une classe \u00e9nerg\u00e9tique.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
