Dyna-Glo 50,000 BTU Forced Air Heater
The Dyna-Glo KFA50DGD is a compact forced-air kerosene heater rated at 50,000 BTU. Designed for garages, workshops, and small job sites, it lists heating coverage up to 1,200 sq.ft. The unit includes an Easy Lift Carrying Handle for portability and straightforward placement.
As a forced-air torpedo-style heater, it uses a blower to deliver directional heat rapidly, making it effective for spot heating and warming work areas. The compact footprint helps where storage or transport are considerations. The design focuses on simple operation and mobility.
When evaluating this model, consider that forced-air heaters move warm air but can distribute combustible fumes in poorly ventilated spaces. Always plan for proper ventilation and follow manufacturer instructions for fuel type and maintenance to sustain performance.

The Mr. Heater 80,000 BTU forced-air model offers multi-fuel compatibility, accepting kerosene, filtered diesel 1 and 2, fuel oil 1 and 2, and Jet A fuel. At 80,000 BTU, it is suited for larger spaces up to approximately 2,000 sq.ft.
Key utility features include a built-in thermostat for temperature control and LED troubleshooting diagnostics to assist with maintenance and operation. The multi-fuel capability adds convenience where kerosene supply may be limited or when diesel is preferred at job sites.
As with similar forced-air units, users should ensure adequate ventilation and observe safety clearances. The combination of higher output and fuel flexibility positions this heater for varied industrial tasks requiring portable directional heat.
L.B. White Tradesman K125 Portable Heater
The L.B. White Tradesman K125 is a heavy-duty torpedo heater delivering 125,000 BTUH, designed for rugged construction and industrial use. It supports kerosene, No. 1 diesel, and No. 1 fuel oil, providing multi-fuel compatibility for remote or demanding job sites.
Notable construction details include a dual-prong electronic spark ignition, heavy-duty enclosed motor, and brass fuel fittings rather than plastic. These components are intended to increase reliability and longevity under continuous use.

This model emphasizes durability and on-site dependability. The focused, high-output design is intended to provide strong directional heat where speed and robust performance are priorities. Proper fuel filtration and routine maintenance are important for sustained operation.
Sunfire SF150 Radiant Diesel/Kerosene Heater
The Sunfire SF150 is a radiant-style industrial heater rated at 150,000 BTUs with multi-fuel capability for diesel, kerosene, and #2 fuel oil. This model highlights quiet operation and low odor combustion by burning fuel more completely.
Its features include a 19-gallon tank with an approximate 19-hour runtime at stated flow rates. Radiant heaters like the SF150 heat objects and people directly, making them less affected by drafts and preferable for enclosed shops, warehouses, and pole barns.
Because radiant units do not rely on forced-air circulation, they provide targeted warm zones and reduce airborne dust movement. For indoor use, review ventilation and clearance requirements. The SF150 is positioned for larger industrial spaces that benefit from quiet, continuous radiant heat.
Sunfire SF120 Radiant Heater
The Sunfire SF120 offers 120,000 BTUs of radiant heat and is rated to heat areas up to around 2,800 sq.ft. It emphasizes fuel efficiency with a 14-gallon tank and long runtime, plus low-odor combustion for indoor-friendly operation.
Radiant heat is particularly effective in drafty or large-volume interiors because it warms surfaces and occupants rather than relying solely on air temperature. The SF120’s quieter operation compared with torpedo-style forced-air heaters makes it suitable for indoor shops and warehouses.
When selecting radiant models, confirm that the radiant pattern and placement align with work zones needing heat. Radiant units typically serve well as primary heat in targeted areas or as a supplement to other heating solutions.
Buying Guide: Choosing An Industrial Kerosene Heater
Selecting the right industrial kerosene heater requires assessing site needs, fuel logistics, and safety. Below are key considerations to guide purchase decisions across forced-air and radiant models.
Heat Output And Coverage
- BTU Rating: Match BTU output to space volume. Higher BTUs are needed for large, open, or poorly insulated spaces.
- Heating Type: Forced-air heaters move warm air quickly for spot heating. Radiant heaters warm objects and people and perform better in drafty or large high-ceiling areas.
Fuel Flexibility And Availability
- Multi-Fuel Capability: Models that accept diesel and different fuel oils provide operational flexibility where kerosene supply may be limited.
- Fuel Capacity & Runtime: Larger tanks and lower flow rates mean longer unattended run times, which matter on remote or long-shift sites.
Durability And Construction
- Materials: Brass fittings, enclosed motors, and heavy-duty frames stand up to jobsite conditions better than lighter-duty components.
- Ignition And Controls: Electronic ignitions and diagnostic LEDs help ensure reliable startups and easier troubleshooting.
Ventilation And Indoor Use
- Combustion Products: Forced-air heaters can distribute fumes if ventilation is inadequate. Radiant heaters with cleaner combustion reduce odor risk but still require proper ventilation.
- Clearance And Placement: Maintain manufacturer-recommended clearances from combustibles and place heaters on stable, level surfaces.
Noise, Drafts, And Work Environment
- Noise Level: Radiant heaters are typically quieter; forced-air torpedo units include blowers that increase ambient noise.
- Draft Sensitivity: If the site is windy or drafty, radiant systems keep heat on target; forced-air performance can be reduced by drafts.
Safety Features
- Automatic Shutoff & Tip-Over Protection: Useful for portable models moved across sites or used around personnel.
- High-Temperature Limit Switches: Prevent overheating in continuous-use environments.
Maintenance And Serviceability
- Ease Of Cleaning: Accessible fuel filters and service panels reduce downtime.
- Parts Availability: Choose brands with replacement parts and local service to maintain uptime.
Comparison Perspectives
- Performance vs. Portability: Higher-output heaters often weigh more and need larger fuel tanks; evaluate transport needs versus run time.
- Radiant vs. Forced-Air: For quiet, low-odor indoor work, radiant units (Sunfire SF120/SF150) provide steady heat. For rapid spot heating and directional warmth, forced-air torpedo heaters (L.B. White, Mr. Heater, Dyna-Glo) are effective.
- Fuel Logistics vs. Cost of Operation: Multi-fuel models offer flexibility but may require filtration and different maintenance routines; radiant heaters may consume fuel more efficiently per hour in some settings.
Use the above criteria to match a heater’s BTU output, fuel type, durability, and heating method to the specific needs of your workshop, job site, or garage. Prioritize safety features and serviceability for continuous industrial use.
