Buying Guide
Fuel type and availability: Propane options are common for torpedo heaters and offer clean, quick heat. Kerosene and diesel units provide strong heat for large spaces but require ventilation and careful fuel handling. Consider what fuels are readily accessible at your site.
Space and BTU needs: Match BTU output to space size. Very large areas benefit from high-BTU, dual-fuel models. For smaller garages, 75,000 BTU units may suffice; for expansive workshops, consider 125,000–175,000 BTU ranges.
Ventilation and safety: All torpedo heaters require good ventilation to avoid suffocation hazards. Look for models with overheat protection, tip-over shut-off, and automatic shut-off on flame loss. CSA/UL certifications are helpful indicators of safety standards.
Run time and fuel storage: Higher BTU often means quicker fuel depletion. Check tank size, fuel efficiency, and expected runtime. If you need all-day heat, pick a model with a larger fuel capacity and longer continuous operation.
Portability and setup: Choose a unit with a manageable weight and a handle or wheels if you need to move heat between rooms or sites. Quick ignition and simple setup save time on job sites.
Fuel compatibility and maintenance: Dual-fuel models offer flexibility but require correct fuel type per operation. Regularly inspect fuel lines, filters, and gauges to prevent odors and smoke buildup.
FAQ
- What BTU range is suitable for a standard garage? – For a typical two-car garage, 75,000–125,000 BTU is often sufficient, depending on insulation and climate.
- Do these heaters require ventilation? – Yes. Proper ventilation is essential to avoid harmful fumes and ensure safe operation.
- Is propane safer than kerosene? – Propane is generally cleaner and easier to handle, but availability and cost vary by location. Kerosene may be preferred where kerosene is standard and ventilation is good.
- Can I use a torpedo heater indoors? – Only in well-ventilated spaces and according to local regulations. Many units are designed for indoor-outdoor use with proper clearance.
- Which heater offers the best balance of heat and runtime? – Models with larger fuel tanks and efficient thermostats, such as dual-fuel kerosene/diesel or propane units with extended runtimes, provide better balance for long jobs.
- What safety features should I look for? – Overheat protection, tip-over shut-off, flame-out protection, automatic shut-off, and, if possible, CSA/UL certification.
