Buying Guide
FAQs
What should I look for in a portable jobsite heater?
Prioritize heating capacity measured in BTUs to match your workspace size, and ensure the heater has safety features like tip-over protection and overheat shut-off. Consider fuel type—electric, propane, or kerosene—based on availability and convenience, and check for durability with rugged construction for job site conditions.
How do propane and electric heaters compare for job sites?
Propane heaters offer higher BTU outputs and are ideal for large, unheated spaces, but require ventilation and fuel storage. Electric heaters are safer indoors and easier to maintain, but may struggle in very cold or large areas due to lower heat output.
Are there specific safety features to prioritize?
Look for heaters with automatic shut-off if tipped over or overheated, as these are critical in busy job sites. Ensure proper ventilation for fuel-based heaters to prevent carbon monoxide buildup, and check for certifications like UL or ETL for added assurance.
What’s the best heater for small vs. large job sites?
For small spaces, a compact electric heater with 1,500–3,000 BTUs is sufficient and easy to move. Large sites may require a propane or kerosene heater with 10,000+ BTUs to heat the area efficiently, but ensure proper airflow and safety measures.
How do I determine the right BTU rating for my needs?
Calculate the cubic footage of your space (length x width x height) and aim for 40–50 BTUs per cubic foot for moderate heating. For poorly insulated or very cold areas, increase the BTU rating by 20–30% to ensure adequate warmth.
Are there any additional features worth paying extra for?
Built-in thermostats and adjustable heat settings allow better temperature control and energy efficiency. Cord storage, handles, or wheels enhance portability, while some models include fans for more even heat distribution.
How do I balance cost and performance when choosing a heater?
Mid-range propane heaters often offer the best value for large spaces, combining high BTU output with reasonable prices. For smaller or indoor areas, investing in a durable electric heater with safety certifications may save money long-term by avoiding fuel costs.
Can I use a jobsite heater in enclosed spaces?
Electric heaters are safe for enclosed spaces, but fuel-based heaters like propane or kerosene require proper ventilation to avoid carbon monoxide buildup. Always follow manufacturer guidelines and consider a CO detector for added safety.
