Buying Guide: Key Considerations
Fuel type: Propane and natural gas units offer easy access to widely available fuels. Kerosene options provide long run times but require safe storage and ventilation. Consider fuel availability and costs in your area.
Space and ventilation: Larger spaces need higher BTU output and proper venting. Ensure adequate ventilation to prevent buildup of gases and to maintain indoor air quality.
Installation: Ceiling-mounted, floor-standing, and portable designs have different installation needs. Measure clearance, ceiling height, and electrical or gas hookups before buying.
Safety features: Look for continuous ignition, overheat protection, flame-out safeguards, and CSA or UL certifications for added reliability in workshops and garages.
Noise level: Some units use quiet burner technology or low-noise fans. If you work in the space while heating, consider noise-sensitive models.
