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.

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 efficiency.
