Bosch Thermotechnology Corp. is a leading provider of high-quality, efficient heating, cooling and hot water systems for residential and commercial applications. We are committed to reinventing energy efficiency by offering comfort solutions that work together as integrated systems and enhance quality of life in an ultra-efficient and environmentally friendly manner.
The Greenstar boiler is available in both wall-hung and floor-standing models. Wall-hung models are perfect for installations where space is limited and floor-standing models help make boiler replacements quick and easy.
Fully-modulating Fan Assembly
A fully-modulating fan helps maximize efficiency by ensuring that the unit operates with optimal combustion. The fan automatically increases or decreases speed according to the amount of gas coming into the boiler, meeting heat demands and saving energy.
Minimize Service Calls
With corrosion-resistant heating blocks designed to optimize clean burning combustion over an extra large surface area, the long-lasting Greenstar requires minimal servicing and reliance on spare parts. This unit comes equipped with an advanced Aluminum-Silicon alloy heat exchanger, offering increased flexibility versus traditional stainless steel.
