Buying Guide: Key Considerations for Oil Fired Torpedo Heaters
- Space coverage vs BTU: Larger spaces require higher BTU and fuel capacity. Match BTU to square footage for efficient heating without overworking the unit.
- Fuel type and efficiency: Oil-fired units typically run on kerosene or diesel. Consider efficiency features like thermostats and ignition systems to minimize fuel use.
- Portability and setup: Wheels and handles improve mobility for job sites. Factor weight and dimensions into your space layout and venting needs.
- Ventilation and safety: Proper ventilation is essential. Ensure carbon monoxide detectors are present and follow all safety guidelines for enclosed spaces.
- Fuel availability and maintenance: Confirm fuel availability in your area and plan for regular maintenance, including fuel filtration and burner checks.
- Usage scenario: For frequent, long-duration heating, select models with larger tanks to reduce refueling interruptions. For occasional use, lighter units may suffice.
