Buying Guide
FAQs
What should I look for in an outdoor space heater?
Look for heaters with high BTU ratings for powerful heating, especially in windy conditions. Consider fuel type—propane, electric, or natural gas—based on convenience and availability. Safety features like tip-over protection and weather resistance are also essential.
How do propane and electric outdoor heaters compare?
Propane heaters offer portability and higher heat output but require fuel refills. Electric heaters are quieter and eco-friendly but need access to an outlet and may have lower BTU ratings.
Are patio heaters worth the investment?
Yes, if you frequently entertain outdoors or want to extend your outdoor season. High-quality models provide consistent heat and durability, making them a long-term value.
What features should I prioritize for safety?
Choose heaters with automatic shut-off, stable bases, and CSA or UL certification. Look for models with heat-resistant grills to prevent accidental burns.
How much heating capacity do I need?
For small patios, a heater with 10,000-15,000 BTUs is sufficient. Larger spaces may require 40,000+ BTUs or multiple heaters for even coverage.
Can outdoor heaters be used in covered spaces?
Yes, but ensure proper ventilation to avoid carbon monoxide buildup with fuel-powered heaters. Electric models are safer for enclosed or covered areas.
What’s the difference between freestanding and wall-mounted heaters?
Freestanding heaters are portable and ideal for flexible layouts, while wall-mounted units save space and provide targeted heating. Choose based on your space and mobility needs.
How do I maintain an outdoor heater?
Clean the burner and reflectors regularly to ensure efficiency. Cover the heater when not in use to protect it from rust and debris.
