En effet, pour chauffer un litre d’eau chaude d’1\u00b0C, il faut 4.18 kJ, ce qui donne pour un bain de 100L par exemple, 418 kJ par degr\u00e9s. Imaginons que l’eau de distribution soit \u00e0 20\u00b0C et que l’on souhaite un bain \u00e0 37\u00b0C (temp\u00e9rature conseill\u00e9e), cela fait presque 2kWh pour ce bain. Pour donner une id\u00e9e, un tel bain pris chaque jour de l’ann\u00e9e, repr\u00e9senterait le quart de la consommation \u00e9lectrique d’un foyer moyen de 4 personnes !
\nJe sais qu’on ne prends pas un bain de 100 litres chaque jour, je voulais juste tenter de mettre un ordre de grandeur sur le co\u00fbt \u00e9nerg\u00e9tique de l’eau chaude.<\/p>\n
Bref, tout \u00e7a pour vous donner des petits conseils pour diminuer votre consommation d’eau chaude :<\/p>\n
– Utiliser des robinets \u00e9conomiseurs d’eau. Ce sont des robinets qui soit proposent un d\u00e9bit maximum r\u00e9duit, soit proposent un cran de d\u00e9bit r\u00e9duit (cela vous permet de tout de m\u00eame avoir des d\u00e9bits classiques lorsque vous le d\u00e9sirez). Un robinet \u00e9conomiseur a un d\u00e9bit de 6-7 litres par minute contre 15 \u00e0 20 litres pour un robinet classique. Ces robinets peuvent aussi s’adapter sur les douches mais renseignez vous sur le pommeau ad\u00e9quat !
\n– Placer des mousseurs sur les robinets permets de diviser le d\u00e9bit de celui-ci en conservant le m\u00eame confort, les mousseurs permettant d’augmenter virtuellement le d\u00e9bit d’eau en y ajoutant de l’air.
\n– Utiliser de l’eau froide lorsque vous n’utilisez pas de grandes quantit\u00e9s d’eau, pour vous lavez les mains par exemple. En effet, lorsque vous vous lavez les mains, si vous vous trouvez \u00e0 plusieurs m\u00e8tres de votre production d’eau chaude sanitaire, il faudra un temps assez long pour que l’ECS arrive jusqu’\u00e0 l’\u00e9vier que vous utilisez. Vous aurez probablement fini de vous laver les mains avant d’avoir de l’eau chaude. En fait, vous avez rempli une partie de la conduite en eau chaude et celle-ci va dissiper sa chaleur dans la conduite (dans le sol\/mur\/cave, etc). Cette quantit\u00e9 d’\u00e9nergie est donc perdue, m\u00eame si on consid\u00e8re qu’elle dissipe sa chaleur \u00e0 l’int\u00e9rieur de la maison, il faut \u00e0 tout prix \u00e9viter ! Cela vous permettra de faire des \u00e9conomies ;-).<\/p>\n
