Bosch Thermotechnology’s Greenstar gas condensing boiler for residential applications is now available in a floor standing version for all eight regular (heat) and combi (heat+hot water) models: regular heat only models 57, 79, 100, 131, 151 MBtuh inputs and combi heat+hot water 100, 131, 151 MBtuh inputs. Greenstar Floor Standing Series boilers are fully modulating condensing boilers that are CSA and ASME approved. All Greenstar models are equipped with pump, pressure relief valve, propane conversion kit, and twin pipe flue adaptor. FS models have an integrated low-loss header and temperature sensor. Regular heat-only models contain an indirect hot water tank sensor; combi models include an expansion vessel. All eight floor standing models retain the same boiler control and heat exchanger offered on existing Greenstar wall-mounted boilers, and offer both room sealed and open flue options.
