Reznor 175,000 BTU LP Propane Garage Heater - Commercial Forced Air

Our review of the Reznor 175,000 BTU LP propane heater finds it best suited for commercial and industrial spaces that need reliable, high-output warmth. In this review the bottom line is clear: the UDXC-175 delivers robust heating capacity with dual output settings and a heavy-duty construction that favors warehouses, large garages, and workshops where continuous performance and easier maintenance matter most.

Key Features

• High output: The 175,000 BTU rating with two heat levels provides flexible warmth from milder low-fire operation to high-fire for the coldest days.
• Propane conversion: Included LP kit converts the unit for liquid propane operation so it works where natural gas is not available.
• Durable heat exchanger: TCORE2 titanium-stabilized aluminized steel construction enhances longevity in demanding commercial environments.
• Quiet forced air: Low static pressure axial propeller fan with vibration isolation keeps sound and vibration down while moving large volumes of air.
• Service access: Removable front face and hinged access door with quarter-turn latch make routine maintenance faster.
• Controls and safety: Integrated circuit board with display, built-in disconnect, and status LED gives clear diagnostics and modern control.

Who It's For

The UDXC-175 is aimed at business owners, shop managers, and contractors who need a ceiling-mounted or wall-mounted commercial heater capable of servicing large open areas like garages, factories, and warehouses. Installers will appreciate the LP conversion kit and compatibility with category 1 double wall B-vent for flexible venting.

Customers seeking a small residential space heater or ultra-quiet home garage unit should look elsewhere; the UDXC series is a commercial-grade forced air heater with higher sound and airflow characteristics designed for larger spaces and professional installations.
