Abstract
Une méthode et un appareil sont décrits pour prévenir la prolifération de bactéries dans un embiellage dun bassin de rétention deau dun chauffe-eau électrique. Différents dispositifs de convection deau sont décrits pour la convection deau chaude de lintérieur du bassin et dans lembiellage du bassin pour accroître la température dans lembiellage suffisamment pour empêcher la croissance de bactéries et laccroître précisément pour atteindre une température de 50 °C à 60 °C, dans laquelle les bactéries Legionella ne peuvent pas survivre. La température dans lembiellage du bassin est surveillée et les dispositifs de convection sont contrôlés pour maintenir la température deau chaude souhaitée. Un avantage supplémentaire de linvention est quelle empêche aussi la stratification de la température de leau dans lembiellage du réservoir.
