Applications ManualBosch Greenstar 11Boiler pump capacity in single zone systemsWhen installing the boiler in a single zone applicationwithout primary/secondary piping, it is critical not tooverload the pump. Use the Greenstar Heating or CombiBoiler in this setup only in low pressure baseboardapplications. Radiant floor, panel radiator, or multi-zoneapplications require primary/secondary piping. Do notinstall zone valves with this system.Recommended maximum: 70' (21 m) of 3/4" baseboardat a 20 F delta T and a flow rate of 4.0 gpm. This allowssufficient reserves for the necessary supply and returnpiping plus elbows.Alternatively determine the system pressure drop on a caseby case basis to verify that the boiler pump is capable ofdelivering the required flow rate. Table 2 provides as anexample the pressure drop of 100’ of 3/4” baseboard andits relevant heat output.Water FlowPressure Drop per 100'MBH output per 100’ at shown Medium Water Temperatureand 65 F Room TemperatureGPMfeet of head110 F120 F130 F140 F150 F160 F170 F180 F44.3751612263238465461Tab. 2 Pressure drop and heat output for ¾” baseboardAdd to that the pressure drop of supply and return pipingplus elbows and other devices like check valves.Use the pump curves on the following page to verify thatthe pump is capable of delivering the needed flow rate forthe given pressure drop of the system.In order to save as much energy as possible andkeep water circulation noises to a minimum, selectthe lowest possible pump speed.If the working pressure cannot be met, use primary/secondary piping.Bosch Thermotechnology Corp.Data subject to change
