Bosch Greenstar 100 Combi Gas-Fired Wall-Hung Condensing Boiler 100,000 BTU (ZWB28-3)

SKU: 7738100002

$3,927.00

The Greenstar Combi 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. 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. 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.
