Benefits
Compact Design
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.

Product Update
Greenstar boilers have been updated to include a larger diameter pipe leading to the pressure relief valve. This is to eliminate potential confusion in local code interpretations. The diameter of the pipinghas increased from 18mm to 22mm. Replacement parts have been updated to include new part numbers and are not backwards compatible to fit older units.
Old Greenstar models will continue to be sold as they still meet current requirements and are not affected in any way.
