    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. They are equipped with highly durable heating blocks that are corrosion resistant and designed to optimize clean burning combustion over an extra large surface area, which requires minimal servicing and reliance on spare parts during the boiler's lifetime.

    FW200 weather compensation control
    The included FW200 digital thermostat and outdoor reset boiler control acts as the nerve center of a home's heating system. Programmable up to six switching times throughout the day, this interface can be installed within the appliance or be wall mounted in any location throughout the home.

    Heatronic III control
    Bosch Heatronic III, a device integrated into the base of the boiler, provides instant access to the hot water and heating controls. Optional system controls are accessible, while instant feedback to the end-user along with a built-in diagnostics module effortlessly pinpoints operational issues. The exclusive keypad safety lock feature prevents unwanted tampering with the controls.

    Plated stainless steel heat exchanger
    All Greenstar Combi boilers are equipped with a high-strength stainless steel secondary exchanger and burner with double passage - ensuring consistent temperature output based on demand. The DHW hot water temperature control limit of 140 Degrees F helps prevent scale build-up within the heat exchanger.

    Full modulating fan assembly
    A full modulating fan automatically increases or decreases its speed according to the amount of gas coming into the boiler depending on the heat demand. 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.

    3 Speed Grundfos Integrated Pump
    All Bosch Greenstar Boilers include the 3 Speed Grundfos Integrated Pump.
