Outdoor and Patio β FAQ
How many BTUs do I need for my patio?
Calculate 20-30 BTU per square foot of patio space. A 200 sq ft patio needs 4,000-6,000 BTU minimum. For exposed areas or cold climates, double that figure. Most full-size propane heaters deliver 40,000-50,000 BTU, covering 250+ sq ft.
Can I use a propane heater on a covered porch?
Only if the ceiling exceeds 10 feet high and two sides remain open for ventilation. Never use in fully enclosed spaces due to carbon monoxide risk. Electric infrared heaters are safer for covered areas since they produce no emissions.
What's the difference between pyramid and mushroom heaters?
Pyramid heaters distribute heat more evenly using a vertical quartz tube with visible flames, creating ambient light. Mushroom-style heaters focus heat downward in a concentrated circle, often more efficient but less visually appealing. Both perform similarly in windless conditions.
How much does it cost to run a patio heater?
Propane costs $1.50-2.00 per hour at full blast using a 20lb tank. Electric heaters cost $0.18-0.25 per hour at 1500W depending on local rates. Halving the heat setting roughly halves operating costs for both types.
Are patio heaters safe to leave unattended?
Never leave propane heaters running unattended. Electric models with tip-over and overheat protection pose less risk but should still be shut off when leaving. Always extinguish flames before wind speeds exceed 15 mph or when not actively monitoring.
Do I need a cover for my patio heater?
Yes, covers extend lifespan by protecting burners and electrical components from moisture and debris. Use breathable, water-resistant covers specifically designed for your heater style. Even waterproof models benefit from covering during extended storage periods.
