It Claims Coverage Up To Approximately 165 Square Feet, With Two Heat Settings And An Adjustable Thermostat To Control Comfort. Electric Heaters Offer Zero Combustion Emissions, Making Them Appropriate For Enclosed Spaces Where Propane Is Not Preferred.
Features Emphasize Rapid Warm-Up And Simple Controls. Use Considerations Include Confirming Circuit Capacity Before Use On Jobsite Electrical Systems, Ensuring Ground-Fault Protection Where Required, And Locating The Heater Clear Of Combustible Materials For Safety.
Flame King High-Output Forced Air Heater
The Flame King Model Is A 60,000 BTU Propane Forced-Air Heater Designed For Large Jobsite Areas And Construction Settings, With A Claimed Coverage Up To 1,500 Square Feet.

Buying Guide
This buying guide covers the primary considerations when selecting a portable jobsite heater. Compare heat type, fuel/power, safety, portability, and suitability for your specific jobsite conditions.
Heat Type And Coverage
- Radiant Heaters (infrared): Heat Objects And People Directly; Efficient For Targeted Zones And Small To Medium Spaces.
- Forced-Air Heaters: Move Hot Air Quickly To Heat Large Volumes; Better For Big, Open, Or Drafty Areas.
- Electric Fan Heaters: Produce No Combustion Byproducts; Ideal For Enclosed Spaces With Reliable Power.
Power Source And Fuel
- Propane: Highly Portable, High Output, But Requires Ventilation And Safe Fuel Handling.
- Electric: Clean Operation For Indoor Use When Power Is Available; Watch Circuit Load And Extension Cord Ratings.
- Cordless/Hybrid: Some models (e.g., DEWALT) use batteries to power accessories while the heater runs on propane; helpful for accessory lighting and USB power on remote sites.
Safety Features
- Look For ODS (Oxygen Depletion Sensor), Tip-Over Shutoff, And Overheat Protection On Units Used Near Or Inside Enclosed Areas.
- Forced-air propane heaters typically require more ventilation; ensure compliance with jobsite safety rules and local regulations.
- Verify certifications (CSA, ETL) And Follow Manufacturer Instructions For Clearances From Combustibles.
Runtime, Fuel Capacity, And Efficiency
- Check Claimed Run-Time Based On Tank Size And BTU Setting; Dual-tank designs Can Provide Longer Continuous Use.
- Higher BTU Is Not Always Better If You Need Localized Heat; Adjustability Helps Manage Fuel Use And Comfort.
Portability And Durability
- Consider weight, handles, and skid resistance for transporting across rough job sites.
- Metal construction and weather-resistant components extend service life in construction environments.
Noise, Airflow, And Use Case
- Electric fan heaters and forced-air propane heaters can produce noticeable noise; consider noise-sensitive environments.
- For spot heating of workers, radiant heaters are effective; for whole-bay warming, forced-air units may be necessary.
Power And Electrical Considerations
- Electric heaters require appropriate circuits; confirm amperage and GFCI protection where required.
- Cordless accessories (lights, USB) can be useful—verify battery compatibility and runtime expectations.
Installation, Maintenance, And Storage
- Inspect hoses, fittings, and igniters before each propane use. Maintain clean air inlets for electric heaters.
- Store propane cylinders safely and follow local codes. Keep units dry and covered when not in use.
Comparison Perspectives
- For small enclosed workshops with power: electric heaters minimize combustion risk.
- For remote or open job sites without electricity: portable propane radiant heaters (DEWALT, Mr. Heater) offer portability and direct warmth.
- For large construction areas needing rapid warming: high-BTU forced-air models (Flame King) provide necessary output but require ventilation planning.
- When accessory power and light are valuable: battery-capable models like the DEWALT provide added utility beyond heat.
