    The Bosch Greenstar Combi 151P Gas-Fired Wall-Hung Condensing Boiler provides Space Heating and handles Domestic Hot Water (DHW) with up to 98.7% efficiency and 36 to 151P.6 MBH inputs! The new Bosch Greenstar condensing boiler line is engineered to offer the ideal solution for residential heating and hot water needs at an affordable price, without compromising quality or fuel economy.

    The Bosch Greenstar Combi 151P is the same as the Bosch Greenstar Combi 151 EXCEPT that it does not come with the internal expansion tank. The P indicates that this is the Professional version and is for installers who provide their own external expansion tank.

    The Bosch Greenstar series features industry-leading design & technology components built for years of reliable operation & optimal energy efficiency.

    Al-Si Heat Exchanger
    Each unit features an ASME approved Al-Si heat exchanger constructed of advanced magnesium-aluminum-silicon alloy offering increased flexibility versus traditional stainless steel. This highly durable heating block is corrosion resistant and designed to optimize clean burning combustion over an extra large surface area. The heat exchanger has a coating that prevents scale build-up, reduces service, maintains high efficiency and extends the life of the boiler.

    Plated Stainless Steel Heat Exchanger
    All Greenstar Combi boilers are equipped with a high-strength stainless steel flat plate heat exchanger with double passage ensuring consistent DHW temperature output based on demand. This heat exchanger, with its large surface area and advanced technology, allows the boiler to use a lower water temperature and to condense even while producing DHW for greater efficiency and helps reduce the build-up of scale within the heat exchanger.

    Full Modulating Fan Assembly
    A full modulating fan automatically increases or decreases its speed depending on the heat demand controlling the amount of gas coming into the boiler. This process, called modulation, prevents the boiler from either having too little or too much air in the unit for optimal combustion ensuring high efficiency.

    Heatronic III Boiler Control
    Bosch Heatronic III, a device integrated into the boiler, provides instant access to the hot water and heating control buttons. Furthermore it enables the easy setting and testing of many customized appliance functions and applications. The exclusive keypad safety lock feature prevents unwanted tampering with the control.

    CRC200 Comfort Room Control
    The CRC200 acts as the nerve center of a home's heating system. The CRC200 is a programmable controller with an integrated temperature sensor and can be used as a boiler control or in conjunction with the CZM100 Comfort Zone Manager as a room controller. It comes with back light and features a time program for heating and indirect hot water tank. Effective August 23, 2021 the Bosch Greenstar CRC200 Comfort Room Control (7738111034) is NO LONGER included with the Bosch Greenstar Wall-hung boilers.

    FW200 Weather Compensation Boiler Control
    The FW200 digital thermostat and outdoor reset boiler control can handle one zone and is programmable for up to six switching times throughout the day. The FW200 can be installed within the appliance or be wall mounted in any location throughout the home. Providing instant feedback to the end-user along with the built-in diagnostic effortlessly pinpoints operational issues. The Bosch Greenstar FW200 Weather Compensation Boiler Control (87182262150) is an optional accessory for both the Greenstar Wall-hung and Floor-standing boilers. Please note that the FW200 Weather Compensation Boiler Controller is not compatible with the CZM100 Zone Manager, CRC100 and CRC200 Room Controllers.

    3-Speed Grundfos Integrated Pump
    All Bosch Greenstar Floor-Standing (FS) Boilers include the 3-Speed Grundfos Integrated Pump.
