Superior design
& components
Al-Si heat exchanger
Each unit features an ASME approved Al-Si heat exchanger constructed
of advanced Magnesium-Aluminum-Silicon alloy - offering increased
exibility 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°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 efciency.
The new Bosch Greenstar series features industry-leading design & technology
components built for years of reliable operation & optimal energy efficiency.
