The Sterling “XF Series Convertible Venting Type Tubular Gas-Fired Unit Heater offers a highly efficient, extremely durable alternative to the traditional clam shell design. XF Series gas-fired unit heaters offer the latest tubular heat exchanger technologies with an innovative "In-Shot" burner system for superior durability, reliability, and performance in a commercial unit heater. Sterling warranties the heat exchanger, flue collector, and burners of each heater to be free from defects in materials and workmanship for 10 years. 


Standard energy saving features like the direct spark ignition and power venting reduce standby losses and offer improved seasonal efficiencies. The model XF unit is certified by ETL as providing 83% thermal efficiency. 


The Sterling Model XF unit heater is ETL certified in accordance with categories I and III venting requirements. This certification allows units to be vented both vertically and horizontally using either single wall or double wall venting materials. This venting flexibility of the Model XF unit heater makes installation easier and more cost effective by allowing the installer to use existing venting components.
