Reznor UDXC-150 Natural Gas — 150,000 BTU
The Reznor UDXC-150 is a gas shop heater designed for indoor spaces such as garages, warehouses, and industrial facilities. It runs on natural gas and delivers 150,000 BTU with an 83% thermal efficiency rating, making it a robust choice for large-area heating. This unit is configured for ceiling mounting, with the option to adapt to a wall installation using compatible brackets. It emphasizes quiet forced-air operation and a low-static propeller fan for steady performance in busy environments. Mounting hardware is typically sold separately, allowing flexible installation tailored to ceiling heights and ductwork.
Reznor UDXC-400 Natural Gas — 400,000 BTU
The Reznor UDXC-400 provides a high-capacity heating solution for expansive spaces such as large warehouses or manufacturing floors. With an output of 400,000 BTU and the same 83% efficiency rating as smaller units, this ceiling-mounted unit is designed for high-demand environments. It supports ceiling suspension with four threaded-nut retainers and works as part of a natural gas system, with mounting options sold separately. The design prioritizes quiet operation and consistent air delivery to keep work areas comfortable during peak shifts.
Reznor UDXC-45 Propane — 45,000 BTU
The UDXC-45 propane heater is a compact option for smaller industrial or commercial spaces that prefer propane. Rated at 45,000 BTU with 83% efficiency, it suits garage shops and mid-size facilities needing reliable heating without extensive ductwork. It features four suspension points for ceiling mounting and is designed to operate as a gas-fired interior heater, with mounting accessories sold separately to fit different configurations.
Reznor UDXC-150 Propane — 150,000 BTU
The UDXC-150 propane model provides the same 150,000 BTU output as its natural gas counterpart but runs on propane. It is designed for indoor use in industrial spaces like garages and warehouses. Four threaded-nut retainers support ceiling mounting, and the unit is intended for suspended installation with mounting hardware sold separately. Its efficiency rating remains high for propane-powered garage and workshop heating systems.
Mr. Heater Big Maxx MHU80NG — 80,000 BTU
The Mr. Heater F260560 Big Maxx MHU80NG natural gas unit heater delivers 80,000 BTU and is compact enough for medium-to-large spaces up to approximately 2,000 square feet. It supports vertical or horizontal venting and offers convenient outside access to thermostat and gas connections, simplifying installation in mixed-use facilities. This unit is suitable for garages or shops that require a reliable gas-fired heat source with straightforward servicing.
Buying Guide: Key Purchase Considerations
Choosing the right gas heater for a warehouse or large workshop involves evaluating space size, mounting options, fuel type, energy efficiency, and maintenance needs. Below are several perspectives to help guide a balanced decision:
- Space and BTU requirements: Larger spaces demand higher BTU outputs. If your facility covers many thousands of square feet, units in the 150,000–400,000 BTU range are typical, while smaller shops may suffice with 45,000–80,000 BTU. Consider ceiling height and airflow when estimating capacity.
- Fuel type and availability: Natural gas provides steady, economical heating where a gas line is present. Propane models offer flexibility in locations without natural gas access but may incur higher fuel costs. Evaluate local fuel pricing and supply reliability.
- Mounting and installation: Ceiling-mounted configurations save floor space and promote even heat distribution. Confirm compatibility with your ceiling height, brackets, and ducting plans. Some units require mounting hardware sold separately; verify included components.
- Efficiency and operating costs: Look for units with high thermal efficiency ratings (around 83% is common for many Reznor models). Higher efficiency reduces fuel consumption over time, contributing to lower operating costs in large areas.
- Ventilation and exhaust: Some gas heaters support vertical or horizontal venting. Ensure your facility has appropriate venting outlets and clearance for exhaust, as well as any local building codes or ventilation requirements.
- Maintenance and diagnostics: Seek models with reliable ignition systems and diagnostic indicators. Indoor units exposed to industrial environments benefit from straightforward service access and robust construction to withstand dust and vibration.
- Durability and warranty: Industrial heaters should withstand frequent use in commercial settings. Check warranty terms, service availability, and the supplier’s reputation for parts and support.
- Safety considerations: Installations should follow manufacturer guidelines, including clearance from combustibles, proper electrical connections, and compliant venting. Periodic maintenance is essential for safe operation.
Overall, the best choice balances volume heating needs, installation practicality, and ongoing fuel costs. For large warehouses, higher BTU natural gas models often provide efficient, consistent warmth, while propanegar models offer installation flexibility where gas pipelines are absent. Always consult installation professionals to ensure compliance with local codes and proper sizing for your space.
