Buying Guide

What should you consider when choosing a fan-forced propane heater?

  • Space size and target area: For up to 1,500 sq ft, 60,000 BTU units are usually adequate; for larger spaces, consider 100,000+ BTU models.
  • Portability vs. permanence: Heavier, higher-output models are less portable but better for fixed job sites.
  • Ventilation and safety: Ensure proper ventilation in enclosed areas. Look for features like tilt shutoff, flame-out protection, and high-temperature limits.
  • Power source compatibility: Most models run on liquid propane tanks; check regulator compatibility and altitude specifications if you are in mountainous areas.
  • Durability and construction: Steel or carbon steel bodies withstand job-site conditions; consider weatherproofing for outdoor use.
  • Maintenance and fuel management: Understand maintenance needs and how easy it is to source fuel and spare parts.

Frequently Asked Questions

  1. What size heater do I need for a 1,500 sq ft space?
