A good patio heater extends your outdoor season by months. We tested propane mushroom heaters, electric infrared heaters, and wall-mounted options to find the best combination of heat output, coverage area, and design for every outdoor space.
The AZ Patio Heater is the most popular freestanding propane patio heater for good reason. 46,000 BTU heats up to 225 square feet, the stainless head radiates heat in a 360-degree 15-foot radius, and the auto shut-off valve engages if the heater tips. The practical choice for most patios.
Bromic's Smart-Heat is the premium outdoor electric heater used in upscale restaurant patios worldwide. The directional quartz heating element projects focused infrared heat without wind dilution. Wall or ceiling mounting keeps the heat source out of the way. Smart home integration (Google, Alexa) adds convenient control. The design is clean enough for premium outdoor spaces.
Napoleon's Patioflame brings premium gas appliance quality to patio heating. The visible flame through the glass column provides ambiance that mushroom heaters can't match, the stainless construction handles weather without degrading, and 40,000 BTU provides solid coverage. The right choice for designed outdoor spaces where aesthetics matter.
The Fire Sense Commercial heater threads the needle between AZ's budget price and Napoleon's premium. The hammer tone bronze finish looks substantially more upscale than standard chrome mushroom heaters, the 46,000 BTU output matches premium options, and the construction is solid enough for commercial restaurant use.
The Duraflame infrared tower heater is the budget option for covered patios and smaller spaces where propane isn't practical. The infrared element heats objects and people directly rather than the air, which works in covered spaces. At 1500W it's substantially less powerful than propane, but it's safe to use under overhangs and indoors.
Propane mushroom heaters (40,000-48,000 BTU) produce dramatically more heat than electric options (1,500W = ~5,100 BTU equivalent). Propane is the choice for open patios in cold weather. Electric infrared heaters are safe for covered patios without ventilation, require no fuel management, and are better for mild weather supplemental heating.
A 46,000 BTU propane heater heats a 10-15 foot radius in mild conditions (50-55°F). In colder temperatures (35-45°F) or with wind, effective coverage shrinks. For a 20x20 patio in cool weather, two heaters positioned at opposite corners provides better coverage than one central heater.
Never use propane patio heaters under enclosed overhangs or in partially enclosed spaces — carbon monoxide accumulation is a serious risk. Electric infrared heaters are specifically designed for covered patio and indoor use. All freestanding propane heaters should have a tip-over safety shutoff valve — verify this before buying.
A 46,000 BTU patio heater burns approximately 1 pound of propane per hour at full power. A standard 20 lb propane tank provides roughly 10 hours of heating at full output. Running at medium power (70%) extends this to 14-15 hours per tank. Keep a spare tank on hand for longer gatherings.
Propane heaters should not be used under enclosed or semi-enclosed overhangs due to carbon monoxide risk. Electric infrared heaters are specifically designed for covered patio use and can be safely mounted to ceilings and walls. If your patio is covered, an electric infrared heater is the safer choice.
