Sterling Hvac XF125 Unit Heater 125000 Btu/h

Product Description

The STERLING HVAC XF125 is a gas-fired unit heater rated at 125,000 BTU/h, designed for space heating in commercial and industrial environments. Unit heaters of this type deliver forced warm air directly into the occupied space, making them a practical choice for warehouses, garages, loading docks, and manufacturing facilities. The XF125 is installed by licensed HVAC technicians or mechanical contractors and integrates into a building's gas supply and venting system. Its compact cabinet-and-burner design allows ceiling or overhead mounting to keep floor space clear and distribute heat efficiently throughout large open areas.

The XF125 is suited for commercial and light-industrial heating applications where a centralized duct system is not practical. Typical installations include single-zone open-bay spaces that require direct, localized heat output. The unit is appropriate for natural gas or propane service depending on configuration, and it pairs with standard low-voltage thermostats for on-off or staged control. Facilities managers, mechanical contractors, and HVAC service professionals are the primary installers of this class of equipment.
