Energy-saving & environmental features:

  • High efficiency - up to 98.5% with low-temp applications (96.0% AFUE). Each unit features an ASME approved Al-Si primary heat exchanger constructed of advanced Magnesium-Aluminum-Silicon alloy, offering better flexibility against conventional stainless steel models. 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 service and dependence on additional parts throughout the boiler’s life span.
  • Plated stainless steel DHW heat exchanger - all Greenstar Combi boilers are built with a high-strength stainless steel secondary exchanger and burner with double passage - ensuring dependable heat output based on demand. The domestic hot water temperature control limit of 140°F helps prevent scale build-up within the heat exchanger.
  • Fully modulating fan automatically increases or decreases its speed according to the amount of gas coming into the boiler depending on required heat. This method, called modulation, prevents the boiler from either having too small or too much air in the unit for optimal burning - ensuring high efficiency.
  • Low NOx emissions, ahead of 2012 SCAQMD regulations
  • Easy, intelligent control options optimize efficiency and fuel consumption
  • Low electrical use when the boiler is in standby mode
  • Electronic ignition
  • Anti-cycle and modulation control

    I contacted several companies for an estimate to install new ductless air conditioning system. I found Richair Comfort Solutions; they were very professional and knowledgeable.
