Features and Benefits

Bosch KBR 28-3 and KBR 42-3

Greenstar FS series is designed to upgrade cast iron floor boilers to an ultra-high efficient condensing boiler at lower installed cost by simplifying the installation. The Greenstar FS series has the same footprint as most existing floor boilers, and because it’s floor standing there’s no additional cost to build a wall or move the boiler to an outside wall. Additionally, the pre-piped internal low loss header eliminates the need to add any primary/secondary piping. All connections are conveniently located on the back of the boiler for quick and easy access, and venting can be done with 2″ PP, flex PP, concentric PP, PVC or CPVC.
  • 95% AFUE efficiency
