Buying Guide: Key Purchase Considerations
- Heat output and space: Match BTU range with room size. For large garages or job sites, aim for models in the 125,000 BTU range with coverage up to 3,000–4,200 sq ft where possible.
- Fuel safety and ignition: Look for pulse or quiet burner technology, high-temperature limit switches, thermoelectric safety valves, and auto shut-off features to reduce risk during operation and outages.
- Portability and durability: Rugged construction, sturdy handles, and a balanced weight help with transport on uneven job sites. Consider models with CSA certification for compliance and safety.
- Ventilation and odor: Ensure proper ventilation in enclosed spaces and select units with features that minimize odors and emissions. Low-noise operation improves worksite environments.
- Fuel compatibility and altitude: Check regulator compatibility for large propane tanks and, if you operate at high altitudes, choose heaters designed for high-altitude use.
- Runtime considerations: 100+ lb cylinders provide longer run times on some models; verify how long a full tank lasts at the chosen setting to plan workflow and restocking.
- Safety accessories: Ensure hoses, regulators, and safety shut-off mechanisms are included or readily available, reducing setup time and risk of leaks.
