A blend of advanced engineering and high-quality materials, unit heaters are perfect for commercial applications and the garage or workshop in your Portland home. Available in 2 designs and several capacities, Lennox puts them through rigorous quality testing for long-lasting performance.

Tubular heat exchanger is the key

It’s curved design provides superior heat transfer by exposing the entire heating surface to the open air. Its rounded surfaces minimize air resistance to allow even heating across all surfaces, which decreases stress on the heat exchanger.

Safety valves and switches – automatic shut-off
Control board with diagnostics – helps in troubleshooting
