SunFire Radiant Heater – 150,000 BTUs Diesel/Kerosene Portable Industrial Heater (SF150)

Type And Use: A high-output radiant heater designed for large spaces where targeted heat is needed without excessive airflow. Radiant heating warms objects and people directly, making it suitable for shops, pole barns, warehouses, and job sites.
Key Features: Rated at 150,000 BTU with a claimed coverage up to about 3,500 sq ft. Runs on diesel, kerosene, or #2 fuel oil and includes a large tank for extended run times. Manufacturer highlights quiet operation and a design that minimizes odors and fumes by burning fuel efficiently.
Safety & Practical Notes: Radiant units require proper ventilation planning for fuel storage and refueling. The unit’s quiet, low-odor combustion is suited for indoor use where ventilation protocols are followed. Ideal where distributed airflow from a forced-air system would be ineffective.
SunFire Radiant Heater – 120,000 BTUs Diesel/Kerosene Portable Heater (SF120)

Type And Use: A slightly smaller radiant model ideal for mid-sized shops, garages, and semi-enclosed areas where concentrated heat is required without creating strong airflow.
Key Features: Provides 120,000 BTU output with a large fuel tank and efficient burn that reduces odor and fumes. The manufacturer cites a run time of approximately 16 hours on its tank capacity, depending on fuel type and flow rate.
Safety & Practical Notes: Radiant heaters like the SF120 are less affected by wind and can be more comfortable for stationary work areas. Ensure fuel-handling procedures and clearance requirements are met. Best for applications where quiet, direct heat is a priority.
L.B. White Tradesman 170N Portable Forced Air Natural Gas Heater

Type And Use: A high-output forced-air natural gas heater designed for construction sites and large outdoor or well-ventilated industrial areas where open-flame/direct-fired heating is acceptable.
Key Features: Produces between 125,000–170,000 BTU/hr with direct-fired technology. Highlights include electronic spark ignition, diagnostic lights for troubleshooting, and a heavy-duty combustion chamber with corrosion-resistant coating.
Safety & Practical Notes: Direct-fired forced-air heaters move combustion gases with the heated air; therefore, they are suitable for open or well-ventilated spaces only. Installation and gas hookups should be performed by qualified personnel. This model emphasizes durability and continuous operation in rugged conditions.
Comfort Zone 10,000W Hard-Wired Garage Heater – 240V Ceiling Mount

Type And Use: An electric fan-forced ceiling-mounted heater intended for indoor industrial and commercial ceilings to deliver wide-area heat distribution without taking up floor space.
Key Features: Offers 10,000W (240V) fan-forced heating with adjustable airflow vents, a digital thermostat, timer, and remote control. Built with a heavy-gauge steel body, fully sheathed heating elements, and enclosed motor for protection in dusty shop environments.
Safety & Practical Notes: Designed for hard-wired installation and ceiling mounting. The built-in thermostat and timer offer control best suited to indoor workshops and garages. Professional electrical installation is recommended for 240V hard-wired devices. Ideal when floor/pedestal heaters would obstruct workspace.
Dr Infrared Heater DR-988A Garage Shop 208/240-Volt Wall-Mount Heater

Type And Use: Electric wall or ceiling-mounted fan-forced heater suitable for medium to large garages, workshops, and light industrial spaces that can provide 208/240V power.
Key Features: Delivers up to 5,600 watts (model dependent) and requires a NEMA 6-30R compatible outlet. Notable for sturdy construction and thermostat-controlled operation for maintaining set temperatures.
Safety & Practical Notes: Requires a dedicated 240-volt circuit and proper receptacle (NEMA #6-30R). Ideal for indoor use where electrical infrastructure supports high-wattage heaters. Provides consistent heat without fuel handling.
Buying Guide: How To Choose An Industrial Portable Heater
Selecting the right industrial portable heater depends on several factors. Review each category below to match your workspace needs, safety requirements, and operational constraints.
1. Fuel Type And Availability
- Electric (240V/208V): Clean, convenient for indoor use where exhaust is unacceptable. Requires adequate electrical infrastructure and possibly professional wiring for high-watt units.
- Diesel/Kerosene (Radiant): High BTU output and long run times; good for large, semi-enclosed areas. Requires fuel storage, refueling procedures, and ventilation planning.
- Natural Gas/Propane (Forced-Air): Continuous fuel supply options are available; ideal for larger outdoor or well-ventilated sites. Gas hookup and safety compliance are critical.
2. Heating Method: Radiant vs Forced-Air
- Radiant Heaters: Heat people and objects directly. Less affected by drafts and quieter. Best for targeted task areas and semi-enclosed spaces.
- Forced-Air Heaters: Heat and circulate air, providing quicker ambient temperature rise across larger volumes. May distribute fumes if direct-fired; ventilation considerations are essential.
3. Output Capacity And Coverage
- Match BTU or wattage to the volume and insulation of the space. Higher BTU models cover larger areas but require more fuel or higher electrical capacity.
- Consider ceiling height, open doors, and airflow patterns—these reduce effective coverage and may require higher capacity or multiple units.
4. Power & Installation Requirements
- Electric Units: Confirm the available voltage and whether a dedicated circuit or NEMA receptacle is required.
- Fuel Heaters: Plan for safe storage and refueling access. Ensure compliance with local codes for indoor use.
5. Safety Features And Compliance
- Look for automatic shut-off, overheat protection, tip-over switches, and enclosed motors where appropriate.
- For fuel-fired units, ensure units are designed to reduce odors and complete combustion if used indoors; follow manufacturer ventilation guidelines.
- Professional installation is recommended for gas hookups, hard-wired electric heaters, and any permanent ceiling mounts.
6. Durability And Build For Jobsite Conditions
- Choose heavy-gauge steel construction and enclosed motors for dusty or rough environments.
- Consider portability features such as handles, wheels, or mounting options depending on whether the unit will be moved frequently.
7. Runtime, Fuel Consumption And Operating Cost
- For diesel/kerosene models, evaluate tank size and gallons-per-hour consumption to estimate run time between refuels.
- For electric heaters, calculate expected operating costs based on wattage and local electricity rates.
8. Noise, Odor, And Worker Comfort
- Radiant heaters are typically quieter and produce less disruptive airflow, which can improve worker comfort during long tasks.
- Forced-air and direct-fired units can be noisier and may require shielding or positioning to minimize worker discomfort.
9. Maintenance And Serviceability
- Check availability of replacement parts, ease of accessing filters or heating elements, and the vendor’s service network for repairs.
- Regular inspection of fuel lines, igniters, and electrical connections prolongs service life and ensures safe operation.
10. Comparison Perspectives
- Best For Indoor, Clean Environments: Electric hard-wired heaters with enclosed elements and thermostats.
- Best For Large Open/Outdoor Sites: High-BTU forced-air gas heaters or powerful diesel units.
- Best For Quiet, Targeted Heat: Radiant diesel/kerosene heaters that focus warmth on work areas without heavy air movement.
- Best For Portability: Units with integrated handles, wheels, or compact footprints and simple fuel or electrical hookups.
Use the above criteria to weigh options based on your space size, fuel access, ventilation, noise tolerance, and installation capabilities. Each heater type presents trade-offs between output, convenience, and operational requirements—choose the model that best matches your site-specific constraints and safety practices.
