Buying Guide: What To Consider Before You Buy
- Space and heat demand: Calculate the volume of the space to determine BTU needs. Larger areas demand higher BTU output for quick, even heating.
- Fuel type and availability: Most options support kerosene or diesel, with some offering multi-fuel capability. Consider fuel availability, odor, and storage requirements on-site.
- Thermostat and safety features: Look for thermostatic control, room temperature display, auto shut-off on low fuel, and overheat protection to improve energy efficiency and safety.
- Ventilation and emissions: Kerosene heaters emit exhaust; ensure proper ventilation and follow local codes for occupied spaces.
- Portability vs. installation: Torpedo-style heaters are portable and versatile, while heavier units may require dedicated mounting or staging space.
- Fuel consumption and efficiency: Higher BTU units burn more fuel. Compare fuel tank capacity and expected runtime per fill to project operating costs.
- Durability and construction: For industrial use, select rugged housings and reliable components designed for continuous operation in rough conditions.
- Maintenance: Regular fuel filter checks and fuel quality are important to minimize smoke and odor and to sustain performance.
