Bypasskessel
Wenn eine Temperaturerhöhung von mehr als 17K in einem Schritt gefordert wird, kann dies
mittels einen Brauchwasserkessel mit integriertem Bypass erzielt werden. Die integrierte
Bypasspumpe gewährleistet die minimale Volumenstrom durch den Kessel.
Bei Anwendung eines Bypasskessels ist die integrierte Bypasspumpe keine Transport-
pumpe. Das Transport des Wassers vom Kessel bis im System soll durch Anwendung einer
externe Systempumpe geschehen. Diese Systempumpe muss dimensioniert werden auf
Grund der gewünschte ΔT. Hierunter finden Sie eine Prinzipzeichnung und zwei Tabellen mit
allen benötigten Informationen zum dimensionieren der Systempumpe. In den Tabellen ist
mit einem Zusatzwiderstand von 10kPa für das System gerechnet.
