Reznor UDXC-45 Propane Heater
The Reznor UDXC-45 is marketed as an indoor propane forced-air heater designed for workshops, warehouses, and industrial spaces. It provides dual heat output levels with a rated maximum of 45,000 BTU and a lower fire setting for milder days. The unit achieves an 83% thermal efficiency, which indicates a high portion of fuel energy converted to heat in the conditioned space.
Key installation options include ceiling suspension points with threaded-nut retainers for hanging, or wall mounting when paired with appropriate brackets (brackets sold separately). The product is described for indoor use and targets medium-sized spaces where forced-air distribution is preferred over radiant-only heating. Consider ventilation requirements and professional installation for gas connections and mounting.
ProTemp PT-125V Propane Heater
The ProTemp PT-125V is a high-capacity propane blower heater with 125,000 BTU output, suitable for larger warehouse footprints. It emphasizes high airflow capability, listing matched direct drive motors and blades rated up to 12,000 CFM, which supports quick air circulation and faster heat distribution across large volumes.

Construction highlights include powder-coated steel guards for corrosion resistance and a design geared toward energy efficiency that minimizes electrical draw—claimed as low as 1.6 amps. This unit is intended where strong forced-air delivery and durable construction are essential. Installation and ducting layout will affect effective coverage and noise characteristics.
Mr. Heater 125,000 BTU Forced-Air
Mr. Heater’s 125,000 BTU forced-air model is designed for commercial and large workshop environments. It includes Quiet Burner Technology that reduces operational sound compared to standard units, a 10-foot hose and regulator for fuel connection, and a high-temperature limit switch for safety.
As a forced-air heater, it focuses on rapidly raising air temperature and circulating warmed air through the workspace. Key considerations for this type include fuel hookup logistics, recommended clearances, and potential ducting or airflow pattern adjustments to avoid cold spots in tall or partitioned warehouses.
Dyna-Glo IR30 Infrared Wall Heater
The Dyna-Glo IR30PMDG-1 is a vent-free infrared wall heater offering variable output up to 30,000 BTU. Infrared units heat objects and people directly rather than warming large volumes of air, providing effective localized warmth in production areas, break zones, or stations within larger warehouses.

This model is labeled as liquid propane ready and claims coverage up to a stated square footage at its maximum output. Vent-free appliances have specific indoor air quality and venting considerations—check local codes and combustion air requirements before installation. Infrared heating may reduce energy spent heating the entire volume when targeted warmth is preferred.
Mr. Heater MH25CVX Convection Heater
The Mr. Heater MH25CVX is a convection propane heater producing 25,000 BTU and is designed to run without electricity. It uses a standing pilot and thermo-electric safety valve that shuts off gas if flame is lost. The unit is positioned for use in garages, job sites, and workshop settings where continuous convection heat and independent operation are desired.
With an advertised runtime on a 20 lb tank and standard hose/regulator connections included, this heater suits smaller warehouse zones or supplemental heat for areas where electrical supply is limited. Convection units slowly warm the air, so placement and airflow considerations will affect how uniformly they heat a larger open space.
Buying Guide For Propane Warehouse Heaters
This guide covers the critical factors to compare when selecting a propane heater for warehouse or similar large spaces. Use these perspectives to match unit capabilities to your facility’s needs and compliance requirements.
1. BTU Output And Space Size
Estimate the heating load for your warehouse by considering volume (square feet × ceiling height), insulation level, open door frequency, and desired temperature rise. Forced-air units with high BTU ratings (e.g., 100k+ BTU) suit large, open areas, while infrared or convection heaters can be effective for targeted zones or smaller volumes.
2. Heat Delivery Method
- Forced-Air Heaters: Rapidly heat and circulate air; good for whole-space warming but may create drafts and require ducting or mounting considerations.
- Infrared Heaters: Radiant heat warms objects and people directly; efficient for spot heating or high-ceiling spaces where heating the entire air volume is inefficient.
- Convection Heaters: Heat the air slowly and maintain a consistent room temperature; best for enclosed zones and quieter operation.
3. Efficiency And Fuel Use
Check the thermal efficiency rating where provided. Higher efficiency means more of the fuel’s energy becomes usable heat. Consider unit cycling, thermostat control compatibility, and insulation improvements to reduce overall fuel consumption.
4. Installation Type And Mounting
Decide between floor, wall, or ceiling-mounted options. Ceiling-mounted forced-air heaters can maximize floor space, while wall-mounted infrared may be ideal for aisle or workstation heating. Confirm structural support and professional installation requirements for gas lines, ventilation, and clearances.
5. Venting, Indoor Air Quality, And Codes
Vent-free units (some infrared models) and vented forced-air units have different combustion air and ventilation requirements. Consult local building codes and an HVAC professional about required fresh air intake, exhaust venting, and carbon monoxide safety measures for indoor propane use.
6. Safety Features
- Limit Switches: Protect against overheating.
- Tip-Over/Flame Failure Shutoff: Important for portable and convection units.
- Certified Components: Look for CSA, UL, or equivalent certifications and follow manufacturer clearance specifications.
7. Noise, Airflow, And Worker Comfort
Forced-air blowers create sound and air movement that may affect comfort and processes. If quiet operation is important, consider models with quiet burner technology or lower RPM fans. Also factor in filtration if dust or particulates could be circulated by forced-air units.
8. Maintenance And Durability
Review material finishes (e.g., powder-coated guards), motor type, and service access. Units in dusty or harsh environments may need more frequent inspection of burners, fans, and gas connections. Choose designs that allow straightforward maintenance by qualified technicians.
9. Fuel Connection And Tank Logistics
Assess whether you will use bulk propane, cylinders, or fixed piping. Longer hose lengths, regulators, and compliant fittings will affect installation flexibility and safety. For high-demand units, bulk-fed systems with professional piping are common.
10. Zoning And Control Options
Plan for zoning if your warehouse has partitions or variable-occupancy areas. Matching heater outputs to thermostats and dampers, or using multiple smaller units rather than one oversized unit, can improve comfort and fuel economy.

Comparison Perspectives
- Large Open Warehouses: Prioritize high-BTU forced-air models (125k BTU class) with robust airflow and professional ducting.
- High-Ceiling Or Intermittent Use Areas: Infrared units are effective when heating people or workstations without spending energy heating the entire air volume.
- Supplemental Or Portable Needs: Convection and portable radiant units provide flexible, electric-free heating for specific zones or temporary workspaces.
