Abstract

L'invention concerne un chauffe-eau (100) pour eau potable, à utiliser à bord d'un bateau ou d'un véhicule. Les gaz chauffés par le brûleur (102) du chauffe-eau (100) sortent du brûleur (102) en (122) et traversent une conduite d'évacuation en (103), laquelle s'étend à travers une chemise d'eau en (110), entourant le brûleur (102). Le brûleur (102) et les gaz chauds qui s'en émanent chauffent l'eau potable. Les éléments d'exploitation sont accessibles depuis une extrémité du chauffe-eau (100) qui peut fonctionner avec du carburant diesel, au lieu des systèmes classiques de chauffe-eau au propane ou électrique, qui peuvent être dangereux. L'entrée et la sortie de la chemise d'eau peuvent se situer à une extrémité. La conduite d'évacuation peut avoir deux sorties.
