Buying Guide
- Space size and heat demand: For spaces up to 1,000 sq ft, 18,000–80,000 BTU units are common; for larger shops, consider 80,000–125,000 BTU models or multiple units to ensure even distribution.
- Fuel and utilities: Natural gas units need a dedicated gas line; propane units require a trustworthy propane supply. Ensure safe ventilation in accordance with local codes.
- Safety features: Look for tip-over switches, oxygen depletion shut-offs, overheating sensors, and CSA/UL certifications to reduce risk in busy work environments.
- Ventilation options: Some models offer flexible venting (horizontal/vertical). Choose based on existing ductwork or exhaust preferences in your space.
- Portability and installation: Portable cabinet heaters suit small spaces or temporary setups; larger units may require permanent mounting and proper clearance from combustibles.
- Run-time and efficiency: Propane heaters with longer run times on a standard 20-lb cylinder minimize interruptions—evaluate hose lengths and regulator quality for reliability.
- Maintenance and service: Consider ease of access for servicing, availability of replacement parts, and warranty coverage for industrial use.
