Abstract

Die Erfindung betrifft einen Wärmeübertrager für brennstoffbeheizte Wassererhitzer, insbesondere für Brennwertgeräte, mit einem inneren Rohr und einem das innere Rohr umgebenden äußeren Rohr. Es wird vorgeschlagen, daß mindestens eine Wandfläche (Mantelfläche, Innenwandfläche) des inneren Rohres (10, 20, 30) ein von der Kreisform abweichendes Profil aufweist. Dadurch wird mindestens eine wärmeübertragende Wandfläche des inneren Rohres vergrößert und der Wirkungsgrad des Wärmeübertragers verbessert.
