Best Outdoor Patio Heaters (2026) — Stop Abandoning Your Patio When It Dips Below 60°F
Fall and spring shoulder season is when your patio is at its best — the humidity is down, the insects are gone, the light is actually good. The problem is the temperature drops to 50°F at 9pm and everyone retreats inside. A good patio heater buys you two to three extra months of outdoor living a year. The question is which type actually delivers enough heat to matter versus which ones warm a six-inch radius and call it done.
We compared the top-rated models across propane standing heaters, portable buddy heaters, and electric infrared options — based on heat output, real-world user feedback, and which situations each type actually works for. All prices and review counts are estimates and may vary.
Top Patio Heaters Ranked
Mr. Heater MH9BX Buddy Portable Propane Heater
4.6★ · ~29,000+ reviews
The heater that actually moves with you — from the patio to the garage to the tailgate. Runs off the same 1-lb propane cylinders as camp stoves, or adapts to a bulk tank. Safety shut-off if it tips over.
✓ Tip-over auto shut-off and low-oxygen sensor — genuinely safe for enclosed porches
AZ Patio Heaters HIL-1821S Standing Propane Heater
4.3★ · ~2,400+ reviews

✓ Stainless steel burner head — won't rust or corrode after wet winters
Duraflame 1,500W Infrared Electric Patio Heater
4.3★ · ~1,800+ reviews
For patios near an outdoor outlet: zero fuel hassle, zero fumes, zero open flame. Infrared heat warms people directly rather than trying to heat the air — you feel it within seconds of turning it on. Works on covered patios where propane ventilation is a concern.
✓ No fuel — never run out mid-dinner party, no propane tank trips
Fire Sense 46,000 BTU Stainless Steel Patio Heater
4.2★ · ~3,100+ reviews
Delivers the same 46,000 BTU mushroom-top heat pattern as the premium brands at a lower entry price. Stainless steel construction handles outdoor moisture reasonably well. A practical choice if you want restaurant-style standing heat without the restaurant budget.

Bromic Heating BH0210001 Tungsten Smart-Heat Electric
4.5★ · ~800+ reviews
The choice for outdoor dining areas, covered patios, and anyone who wants the heater invisible until it's needed. Mounts to walls or ceilings, faces downward, heats a specific zone rather than radiating in all directions. Expensive — but it's the one professionals install.

How to Choose the Right Patio Heater
Most patio heater buyers regret one of two things: buying too small (the heat is insufficient past 55°F) or buying a standing propane heater when their covered patio needed electric. Here's how to get it right.
Propane vs. Electric: The Honest Comparison
Propane wins on raw BTU output and portability — 46,000 BTU from a standing propane heater will warm a group of people in a meaningful radius even on cold evenings. Electric infrared wins on convenience and safety — plug in, instant heat, no fuel runs, no open flame. For open decks and patios where ventilation is unlimited, propane makes more sense. For covered patios and screened porches where you worry about CO buildup, go electric. The Mr. Heater Buddy is an exception — it has a low-oxygen shutoff that makes it safer in partially enclosed spaces, which is why it has nearly 30,000 reviews from everyone from hunters to van lifers.
Standing Heaters: What the 46,000 BTU Number Actually Means
The mushroom-top standing propane heaters all advertise 46,000 BTU and "up to 210 sq ft" of coverage. That number assumes calm air, roughly 50°F ambient temperature. Add wind, drop to 40°F, and that coverage radius shrinks significantly. On an exposed deck where wind comes through regularly, a standing heater will be noticeably less effective than on a sheltered courtyard. If your patio is exposed, consider two smaller heaters flanking your seating area rather than one standing unit in the middle.
Portable Heaters: Who They're Actually For
The Mr. Heater Buddy and similar portable units aren't primarily about patio entertaining — they're for tailgating, ice fishing, hunting blinds, camping, and workshops. On a patio they work, but at 9,000 BTU you're warming immediate personal space, not a seating area. If you want to take a heater camping in fall and also use it on the patio when home, the Buddy is the right choice. If you want to heat a patio for guests, you need a standing propane or mounted electric heater.
Mounted Heaters: The Premium Option Worth Knowing About
Wall and ceiling mounted electric infrared heaters like the Bromic Tungsten are the choice for outdoor dining areas, restaurant patios, and anyone who wants heat that's part of the space rather than an appliance sitting in it. They're directional — point them at the seating area and that zone gets warm. They're invisible when not running. The downside: 240V installation requires a licensed electrician and adds real cost. Worth it for a permanent outdoor entertaining space, overkill for a casual backyard setup.
Winter Storage and Maintenance
Standing propane heaters should be stored upright with the propane tank removed and the valve closed. Most rust failures happen when standing heaters are left outside through winter rain and snow — the burner head collects water and the igniter corrodes. A weatherproof cover (about $20 separately) extends the life of a standing heater by years. Electric infrared heaters can typically stay mounted year-round if rated for wet locations — check the product spec sheet.
Frequently Asked Questions
What is the best outdoor patio heater for a covered patio?
For a covered patio, electric infrared heaters are the safest choice — no combustion, no carbon monoxide risk. The Duraflame tower heater or a wall-mounted Bromic Tungsten work well in covered spaces. If you want propane on a covered patio, ensure there's adequate cross-ventilation and check local code — most jurisdictions require minimum clearances from overhead structures. The Mr. Heater Buddy is rated indoor-safe at low-oxygen sensor cutoff, which gives it more flexibility than standard patio propane heaters.
How many BTUs do I need for a patio heater?
As a rough guide: 10,000–20,000 BTU for a small seating area (under 100 sq ft), 40,000–50,000 BTU for a standard patio (150–210 sq ft), and electric infrared heaters rated 1,500W (about 5,100 BTU) work well for targeted personal heat in smaller spaces. Standing propane heaters at 46,000 BTU can heat a 15-foot diameter circle, making them effective for medium-sized outdoor dining setups. Wind significantly reduces effective heating range — if your patio is exposed, size up or choose a directional mounted heater.
Propane vs. electric patio heater — which is better?
Propane heaters produce more heat output per dollar in cold conditions and work anywhere without an outlet. Electric infrared heaters are cleaner, require zero fuel management, and are safer for covered spaces. The practical split: use propane for large open patios where you want warmth across a wide area, use electric for smaller covered spaces where you want directional heat without fumes. Electric models need an outdoor-rated outlet — check your patio has one before ordering.
Is it safe to use a propane heater under a covered patio?
It depends on the type of coverage and ventilation. A fully enclosed space with no airflow — like a garage — is not safe for propane heaters due to CO accumulation. A covered patio with open sides (pergola, awning, or roof with open walls) typically has enough ventilation for safe use, but check local codes. Models with automatic tip-over shutoff and low-oxygen sensor cutoff (like the Mr. Heater Buddy) add safety layers for partially enclosed spaces. When in doubt, choose an electric infrared heater for covered spaces — zero combustion, zero CO risk.
How much does it cost to run a patio heater per hour?
For a 40,000 BTU propane heater: a standard 20 lb propane tank holds roughly 430,000 BTU, giving about 10–11 hours of run time. At roughly $20–$25 to fill a 20 lb tank, that works out to $2.00–$2.50 per hour of operation. For a 1,500W electric infrared heater: at the national average electricity rate of $0.14/kWh, running at full power costs about $0.21 per hour. Electric wins on operating cost by a wide margin for smaller heaters; propane wins on heat output per dollar for large high-BTU models in cold conditions.
