Advanced Thermal Hydronics announced the release of the KN-Series Plus condensing boilers. Built off the foundation that made the KN-Series a market leader, the KN-Series Plus incorporates class-leading features of the KN-Series with increased efficiencies that make it durable and energy-efficient.
KN-Series Plus boilers are backed by a 25-year heat exchanger warranty, continuing the strong ATH legacy that has made original KN-Series boilers a staple in the condensing boiler market. Delivering what today’s market demands in high energy efficiency and low emissions, KN-Series Plus boilers are ideally suited for “green” building initiatives and LEED projects providing thermal efficiency ratings that meet or exceed federal and state requirements for performance and/or rebate incentives. To achieve these high efficiencies, the KN-Series Plus utilizes a newly designed hydrophobic coated finned stainless steel heat exchanger to work in concert with the existing high efficiency cast-iron heat exchangers.
By using finned stainless steel tubes the KN-Series Plus has increased heat transfer area to maximize efficiency while keeping the same small footprint. The KN-Series Plus is a full variable flow water-side condensing boiler, allowing easy integration into variable flow primary boiler systems. The KN-Series Plus is also certified for use with PVC and Polypropylene vent materials.
