Buying Guide: Key Purchase Considerations
- BTU output and space coverage: For larger spaces, higher BTU models (125k–170k) can heat more efficiently, while smaller areas may benefit from mid-range units (50k–85k).
- Fuel type and availability: Propane torpedo heaters are common for portability, but diesel/kerosene options provide alternatives where propane access is limited. Consider fuel storage, odor, and handling requirements.
- Ventilation and safety: Always ensure adequate ventilation when using torpedo heaters indoors. Look for auto shut-off features, overheat protection, and CSA certification for safety compliance.
- Portability and durability: A rugged build and lightweight handling improve usability on job sites. Check hose length, regulator quality, and stability features like flat bases or skid frames.
- Operational noise and startup reliability: Pulse ignition reduces misfires; consider models marketed as low-noise for environments where sound matters.
- Fuel economy and runtime: Models with longer runtime on a given fuel tank offer less maintenance and downtime, particularly on worksites.
- Maintenance and parts availability: Look for widely available replacement parts and accessible service channels to minimize downtime.
- Multi-fuel capability (where applicable): Some units support kerosene, diesel, and jet fuels, offering flexibility in fuel choice depending on location and access.
- Warranty and CSA certification: Prefer products with CSA certification and reliable manufacturer warranties to ensure long-term support.
