    • Condensing Tankless water heaters maximize energy efficiency by capturing and reusing heat from exhaust gases, achieving up to a 0.95 Uniform Energy Factor (UEF). This high efficiency reduces operating costs and minimizes environmental impact, making them an ideal choice for residential and commercial applications. The integrated recirculation pump ensures that hot water is readily available, reducing wait time and saving water. The primary heat exchanger is constructed from commercial-grade copper, which is highly resistant to erosion, while the secondary heat exchanger is made from type 316L stainless steel to protect against corrosion. Features such as an Air-Fuel Ratio (AFR) sensor, exhaust and water temperature safety controls, and an overheat cut-off fuse enhance reliability and user safety. The heaters also include advanced diagnostics and integrated temperature controls, simplifying installation, troubleshooting, and maintenance.

      Available in both indoor and outdoor models, these heaters offer flexibility to suit various installation needs. Indoor models feature factory-installed power cords and integrated controls, while outdoor models come with a wall-mounted temperature remote controller for added convenience. Easy-link up to four like units for increased flow capacity for larger applications.
