The Sterling XF series propeller-style tubular gas-fired unit heaters offer a highly efficient and extremely durable alternative to traditional clam shell designs. These units combine the latest tubular heat exchanger and in-shot burner technology, delivering the quality and reliability expected from Sterling, with 83% thermal (combustion) efficiency certified by ETL.Notably, the XF unit heater is designed for convertible venting, allowing installation in either standard or separated combustion configurations without modification. For separated combustion, used in environments with dust, corrosive conditions, high humidity, or negative pressure, combustion air piping connects to rear inlet collars, enclosing the burners, spark ignitor, and flue system.
