Quick Product Details: KN20

Condensing, High Efficiency: 2,000,000 BTUs

With an output of 2,000,000 BTUs, the KN20 is built to withstand any harsh environmental conditions that come its way. Engineered with the signature KN Series cast iron heat exchanger and full-modulation condensing boiler performance, the KN20's durability and reliability is second to none.

Regardless of the boiler application size, the KN20 enables low installation cost alongside optimal fuel utilization in a small footprint. And when integrated with HeatNet 3.0 boiler control software, the KN20 can be used in conjunction with other KN Series boilers in a master/member network of up to 16 units and other units using HeatNet 3.0 software, creating a custom boiler network to meet the heating demands of the largest commercial boiler operations.
