How to Choose a Patio Heater or Fire Pit

The right heat is the difference between a patio you use two months a year and one you use six. Choose wrong and you burn through propane for a warm spot the size of a doormat, or buy a fire pit your HOA won’t let you light. Choose well and the backyard becomes the best room in the house from March straight through November.

Heater or fire pit? Start with what you actually want

These two products solve different problems. A patio heater is a heat appliance: it pushes warmth down and out over people so you can sit comfortably in cool air. A fire pit is a gathering feature: it throws light and ambiance, and the warmth is a bonus you feel best when you’re close. Plenty of patios end up with one of each, but if you’re buying your first, decide which job matters more — toasty guests at a dinner table, or a glowing centerpiece to pull chairs around.

Both families live in the same corner of the store as the rest of your outdoor furniture, and the full range of freestanding, tabletop, and built-in options sits together under patio heaters and fire pits. Browse them side by side before you commit — the footprint on your deck often decides for you.

Fuel is the real decision

Everything else — size, style, price — flows from the fuel you pick. There is no single best answer; there’s the best answer for your patio, your rules, and how often you’ll light it.

Propane is the most popular pick for good reason — it’s self-contained, moves with you, and needs no wiring or plumbing. If you go that route, buy a spare cylinder and the right regulator and hose from the start so you’re never cold on a Saturday night; you’ll find tanks, adapters, and fittings under propane kits and fuel. Electric infrared is the quiet hero for covered spaces — anywhere an open flame is risky, a mounted or standing radiant unit warms people without touching the air, and it’s the only type genuinely safe under a solid roof.

Tip: one 20-lb propane tank gives roughly 9–10 hours on a full-size 40,000 BTU heater. If you entertain often, a second cylinder costs less than one ruined evening — keep it filled and stored upright, outdoors, away from the heater.

Sizing: BTUs, reach, and the mistake everyone makes

Heat output is measured in BTUs, and the honest truth is that outdoor heat dissipates fast. A tall freestanding “mushroom” heater at 40,000–46,000 BTU warms a circle roughly 15 feet across — enough for a small seating group directly beneath it. A tabletop unit at 10,000–12,000 BTU heats the people at that one table and no further. The mistake is expecting a single heater to warm an entire open yard; wind and open air win every time.

• Small balcony or bistro table: a tabletop propane or electric infrared unit, 10,000–12,000 BTU, is plenty and won’t overwhelm the space.
• Dining set or conversation area: a full-height freestanding heater at 40,000+ BTU, placed at the edge so heat radiates inward over the group.
• Large or windy patio: two heaters flanking the seating beat one giant unit — overlapping circles cover far more usable space.
• Covered porch or three-season room: electric infrared only. Never run propane or natural gas under a closed ceiling — combustion needs open air.

For fire pits, diameter matters more than BTU. A 28–30 inch bowl or table is the sweet spot: big enough to gather six chairs around, small enough to heat efficiently and store a cover over. Pair the pit with soft landscape and path lighting so the patio still feels finished once the flames die down.

Build quality, safety, and the details that last

Outdoor heat appliances live a hard life — sun, rain, and temperature swings. A few features separate a heater you’ll still love in five years from a rusty disappointment by next spring.

• Anti-tip switch and a wide, weighted base. Non-negotiable on any freestanding heater. It cuts the gas the instant the unit tips — and a broad base or a fillable weight ring keeps it upright in wind.
• Stainless steel over powder-coated steel. Stainless resists rust far better near pools, coasts, and anywhere it rains. Powder-coated steel looks great and costs less, but demands a cover.
• Piezo or electronic ignition. A reliable one-push igniter beats fumbling with a lighter every time. Test it in the store if you can.
• A fitted cover. The single best thing you can do for longevity. Water pooling in a burner or control housing is what kills these units — buy the cover with the heater.
• CSA or UL certification. Look for the mark. It means the gas train and safety cutoffs were independently tested.

Trusted names worth seeking out include Mr. Heater and Dyna-Glo for propane patio heaters, Solo Stove and Breeo for low-smoke steel wood pits, and Napoleon and Bond for gas fire tables. Before you buy anything that burns, check your city and HOA rules — many restrict open wood flames but allow gas, which is exactly why gas fire tables have taken over. Keep a rated extinguisher nearby too; a small one from the fire safety aisle belongs on every patio with a flame.

Frequently asked questions

Buying heat for the patio comes down to three honest questions: warm people or set a mood, what fuel fits your space, and what your local rules allow. Get those right and you’ve added months to your outdoor season. Want to feel the build quality and see the flame before you decide?
