Buying Guide: Key Purchase Considerations
-
<li Indoor vs outdoor use: Vent-free and infrared models are often preferred indoors for quick warmth, but require adequate ventilation and safety monitoring. Outdoor models emphasize weather resistance, portability, and safety features like tip-over switches and flame safeguards.
<li BTU and area coverage: A 30,000 BTU unit typically covers up to 1,000 sq. ft. in efficient scenarios. For highly open layouts or drafty spaces, consider supplementary heat sources or infrared warmth that targets occupants directly.
<li Fuel type and availability: Most options use propane, which provides convenient storage but requires proper cylinders and regulator connections. Some units support dual fuel (propane or natural gas) for flexibility in certain installations.
<li Safety features: Look for oxygen depletion sensors, automatic shut-off systems, flame failure protection, and tip-over switches. CSA or UL certifications indicate compliance with safety standards.
<li Installation and mounting: Wall mounts, ceiling mounts, or portable configurations have different clearance, venting, and space requirements. Ensure you have appropriate clearance from combustibles and adequate ventilation if vent-free.
<li Maintenance and durability: Consider corrosion resistance, burner durability, and ease of cleaning. Outdoor models should be designed with weather-resistant casings and reflectors to maximize longevity.
<li Efficiency and runtime: Fuel efficiency affects operating costs and intervals between refueling. Review listed runtimes at high BTU to estimate daily or seasonal usage.
<li Budget and space constraints: Heaters vary in price and footprint. A compact, higher-efficiency unit may better fit a small shop or garage without sacrificing warmth.
