Lennox LS25 Separated Combustion Unit Heater

The Lennox LS25 Separated Combustion Unit Heater is a top-tier heating solution designed for exceptional performance in harsh environments. With its advanced engineering and high-quality components, this unit heater ensures unmatched durability and efficiency over its lifespan. The LS25 stands out with its superior separated combustion technology, offering a robust heating solution for buildings with challenging indoor environments.

Engineered for Efficiency and Reliability

The LS25 Unit Heater boasts several key features that set it apart. First, it is the most efficient non-condensing unit heater in the industry, delivering maximum performance through its dimpled tubular heat exchanger design. Additionally, the high-temperature silicone gaskets used in the separated combustion process provide a superior seal, significantly reducing leakage rates. This not only enhances the heater's efficiency but also ensures a warm and peaceful environment with ultimate sound quality, featuring 25% less pure tones and projection than leading competitors.

Flexible Applications and Cost-Effective Operation

The LS25 Unit Heater is versatile, offering increased application flexibility and lower operating costs. Its separated combustion models use outside air for combustion, making it ideal for spaces with airborne contaminants, VOCs, and dust. The fresh-air intake box can be rotated 180 degrees, simplifying installation and reducing the number of piping elbows needed. Furthermore, the LS25 models are up to 5% more efficient than standard efficiency direct-fired unit heaters, making them a cost-effective choice for maintaining comfortable temperatures in various settings. With its two-stage heating capabilities, the LS25-250 through LS25-400 KBTUH models efficiently meet the heating demands of any space.
