The iconic tall propane tower heater with mushroom-shaped reflector top. Provides 40,000 BTUs of heat in a 15-ft diameter circle. Portable, widely available, and stores in the garage when not in use.
Pro tip: Position mushroom heaters 6–8 feet from any seating for optimal warmth. Any closer and the heat is uncomfortably intense for face-level guests. The warmest zone is a donut shape 5–8 feet from the heater base.
Compact propane tabletop heater (12,000–15,000 BTUs) that sits on a patio table. Perfect for small balconies, decks, and intimate settings. Runs on 1-lb propane canisters or can be adapted for 20-lb tanks.
Pro tip: Tabletop propane heaters work best in still or lightly breezy conditions — moderate wind blows the small flame out. Consider a windscreen or position facing into the wind for reliability.
Elegant propane pyramid with a glass tube showing the flame column — heats similarly to mushroom heaters but with more visual appeal. The flame visible through the tube provides fire ambiance plus warmth.
Pro tip: Pyramid glass tube heaters need occasional cleaning — dust and insects accumulate inside the tube and reduce the flame visibility. A long bottle brush inserted from the top cleans effectively.
Restaurant-grade propane heaters (50,000–60,000 BTU) built from heavier-gauge stainless and rated for continuous commercial use. The best choice for frequent entertaining — they outlast consumer models 3–5×.
Pro tip: Commercial propane heaters are compatible with quick-connect natural gas adapters from specialty suppliers — allowing you to run them on permanent natural gas lines rather than propane tanks.
Permanently plumbed natural gas version of the mushroom heater — never run out of fuel, no tank storage, lower operating cost. Requires a gas line run to the patio (professional installation).
Pro tip: A natural gas patio heater costs approximately $0.50–$1.00 per hour to operate vs $1.50–$2.50/hour for propane. The gas line payback period is typically 1–3 seasons of frequent use.
Natural gas heater permanently mounted on an exterior wall or fence — provides targeted, directional heat to a specific seating zone. Clean installation with no floor footprint.
Pro tip: Wall-mount heaters need to be mounted at 7–8 ft height for comfortable, even heat distribution without hot spots directly below the unit. Lower mounting creates uncomfortable radiant heat on the heads of seated guests.
A fire table provides both heat and ambiance — the flame typically outputs 30,000–60,000 BTUs. A premium choice: functional heat source, visual fire feature, and tabletop in one piece.
Pro tip: Natural gas fire tables output meaningful heat in a 6–8 foot radius at mid to high BTU settings. At low settings, they're primarily decorative with minimal warming effect.
Wall or ceiling-mount electric infrared tube heater — heats people and objects directly rather than the air. Perfect for covered patios and outdoor rooms where you want targeted, efficient heat.
Pro tip: Infrared heaters warm instantly (no warmup time) and stop instantly when switched off — unlike gas heaters that need minutes to cool. This makes them more efficient for intermittent use.
Electric freestanding heater on a pole — plugs into a standard outdoor GFCI outlet. No gas connection, no propane, no combustion. Safe for covered patios and outdoor rooms with gas restrictions.
Pro tip: Always connect electric patio heaters to a GFCI outlet — outdoor electrical safety code requires this. Never use an indoor extension cord for outdoor heaters; use a heavy-duty outdoor-rated extension cord rated for the heater's wattage.
Flush or surface-mounted ceiling electric radiant panels for covered outdoor spaces — heats from above like the sun. Best for permanent covered porches, pergolas, and outdoor rooms.
Pro tip: Ceiling-mount electric heaters at 8 ft provide excellent heat coverage at seating level. At 10 ft ceiling height, you'll need higher wattage to achieve the same warmth — allow 100 watts per square foot of seating area.
Electric infrared heater with Wi-Fi control — schedule via app, integrate with smart home system. Turn on from the couch before heading outside. Very popular for tech-forward homeowners.
Pro tip: Smart outdoor heaters need a weatherproof outlet and a stable Wi-Fi signal on the patio. If Wi-Fi signal is weak outdoors, a mesh Wi-Fi extender at the patio is cheaper than rewiring.
Small electric tabletop radiant heater (1,000–1,500W) for small balconies and covered areas without gas access. Less output than propane equivalents but no fuel management.
Pro tip: Electric tabletop heaters at 1,500W produce about 5,100 BTUs — equivalent to a small propane tabletop heater. For outdoor use in cold weather (below 40°F), electric tabletop heaters are underwhelming. Consider propane for serious heating needs.
A wood-burning fire pit provides the most heat output (100,000+ BTUs) of any outdoor heating option. Truly warms a large seating circle. Requires seasoned hardwood fuel and more management than gas options.
Pro tip: Burn only seasoned (dried 6–12 months) hardwood — oak, maple, ash, hickory. Green or wet wood produces far more smoke and far less heat. Split logs dry faster than rounds — split before stacking.
A gas fire table provides 30,000–60,000 BTUs of clean, controllable heat with no smoke, sparks, or ash cleanup. The most popular high-end outdoor heating solution for entertaining spaces.
Pro tip: Gas fire tables with lids serve as a regular side table when not in use — a huge functional bonus. Look for tables with stainless steel burners (not aluminum) for longevity in outdoor conditions.
Convert an existing wood fire pit to propane with a drop-in fire pit insert. Produces 60,000–100,000 BTUs with full control. No wood, no smoke, no ash.
Pro tip: Fire pit inserts require the existing fire pit structure to have adequate depth (minimum 12 inches) and width for the burner pan. Check dimensions before ordering — returns are difficult due to size and weight.
A built-in masonry or prefab outdoor fireplace provides the most dramatic, architectural outdoor heat source. Functions as a focal point, room-defining wall, and heat radiator simultaneously.
Pro tip: Prefab outdoor fireplace kits (Belgard, Oldcastle, Napoleon) cost $1,500–$5,000 and install in a weekend on a proper concrete footing. Custom masonry fireplaces start at $5,000 and can reach $20,000+.
On an open uncovered patio: tall mushroom heaters with 15-ft warming radius are most effective. Position one per 200 sq ft of occupied space. Wind is the main enemy — orient heaters or add windbreak.
Pro tip: Wind reduces propane heater effectiveness by 50–70%. On exposed patios, a windbreak (privacy fence, arborvitae hedge, or glass panels) is as important as the heater itself for comfortable cool-weather use.
Under a covered pergola: ceiling-mount or wall-mount electric infrared heaters are ideal. Gas heaters require minimum 18 inches clearance from combustible overhead surfaces. Electric has zero clearance requirement.
Pro tip: Never use propane mushroom heaters under a combustible pergola (wood, fabric) — the mushroom top radiates intense heat upward and poses fire risk within 3 feet of combustible overhead materials. Use electric or wall-mount gas instead.
In a screened porch: electric infrared heaters are the cleanest and safest. Propane heaters in enclosed screened porches require opening two screens for ventilation to prevent CO buildup.
Pro tip: CO (carbon monoxide) detectors are required in any enclosed space where combustion heaters operate. Install a dual smoke+CO detector in your screened porch — this is both a code requirement in most areas and a lifesaving device.
For apartment and condo balconies: a tabletop electric heater or a small electric freestanding heater is most practical. Propane tanks may be prohibited by building rules. Check lease/condo rules before purchasing.
Pro tip: Most urban apartments and condos prohibit propane tanks on balconies due to fire code. Always check building rules before purchasing any outdoor heater. Electric heaters have no restrictions in standard residential buildings.
On a wood deck: electric infrared ceiling heaters for covered decks, electric freestanding for uncovered. If using propane, ensure deck surface is non-combustible stone, composite, or tile within 6 ft of the heater base.
Pro tip: Propane heater bases get extremely hot and can melt composite decking and char wood decking. Always use an insulated pad (concrete paver, stone tile) under propane heaters on composite or wood decks.
A suspended infrared heating dome that hangs from a pergola or porch ceiling — heats the space directly below. Very popular for dining areas. Looks architectural and modern.
Pro tip: Hanging dome heaters must be mounted into structural ceiling joists or beams — not just drywall or pergola fascia boards. These heaters weigh 15–40 lbs plus the hanging force of heating element vibration.
Radiant heat electric mats installed beneath pavers or concrete extend outdoor season dramatically. Feet stay warm even on cold evenings. Very popular under covered outdoor rooms and dining areas.
Pro tip: Outdoor radiant floor heating requires professional installation — the heating mat must be embedded in mortar/concrete, and the electrical connection requires a weatherproof outdoor circuit with GFCI protection.
A freestanding bioethanol burner produces real flames with zero smoke, zero gas lines, and zero cleanup. Produces about 10,000 BTUs — decorative heat rather than serious warming. Modern, clean, and visually stunning.
Pro tip: Bioethanol fuel costs approximately $3–$5 per hour of burn time — 2–4× the cost of propane per BTU. Bioethanol is best viewed as an aesthetic flame feature that happens to produce some warmth.
A freestanding clay or cast iron chiminea — a traditional front-opening wood or charcoal-burning fire vessel. Provides directional heat from the opening. More contained than an open fire pit.
Pro tip: Clay chimineas must be cured before first use (build progressively larger fires over 3 sessions). Never use accelerants (lighter fluid, gasoline) to start fires in clay chimineas — the thermal shock cracks them.
Pair solar panels with a battery system to run electric infrared heaters off-grid. Very emerging tech in 2026 — requires significant solar capacity (2kW+ system) for meaningful heating output.
Pro tip: A solar-heated outdoor heater requires approximately 400–600W of solar capacity per 1,500W of heater output (accounting for battery charging losses). This is a premium, eco-conscious setup rather than a budget option.
Understanding BTUs for outdoor heaters: Under 10,000 BTU: tabletop decorative. 10,000–20,000: small area supplement. 30,000–50,000: primary heat for 100–150 sq ft. 50,000–100,000: large area or cold climate use. Fire pits: 100,000+ BTU.
Pro tip: Outdoor BTU requirements: multiply sq ft of seating area × 200 BTU (mild climate), × 300 BTU (cold climate). A 150 sq ft patio in Chicago needs approximately 45,000 BTU minimum for comfortable fall use.
Propane: portable, highest heat output, ~$2/hour operating cost, requires tank management. Natural gas: permanent, lowest operating cost (~$0.50/hour), requires gas line. Electric: easiest setup, safest indoors, most efficient, ~$0.15–$0.30/hour, limited output.
Pro tip: For most homeowners who entertain 20–40 times per year outdoors, the most cost-effective setup is: 2 portable propane heaters ($200 each) for the patio + conversion to natural gas if entertaining increases to 60+ times/year.
Outdoor heaters need weather protection. Look for: IP44 minimum (splash resistant), IP55 for rain exposure, powder-coated or stainless steel frames (not painted aluminum, which corrodes rapidly). Store propane heaters under cover when not in use.
Pro tip: Even 'outdoor-rated' heaters last longer with cover use when not in operation. Most patio heater covers cost $15–$40 and double heater lifespan by preventing UV and moisture damage to burner components.
Only purchase outdoor heaters with CSA (Canada) or UL (United States) safety certification listed on the product. These organizations test heaters for fire, gas leakage, stability, and electrical safety. Non-certified heaters from unknown brands may lack safety shutoffs.
Pro tip: Check for tip-over safety shutoff switches on all portable heaters — these cut gas or power if the heater falls. This is a mandatory safety feature. Never use a portable heater without a tip-over shutoff.

Try Yardcast Free →The best overall outdoor patio heater for most homeowners: a 48,000 BTU natural gas or propane mushroom tower heater from a CSA-certified brand (AZ Patio, Napoleon, Bromic). For covered patios: ceiling-mount electric infrared (Bromic, Schwank) for efficient, directional heat with zero safety clearance concerns. For pure ambiance + warmth: a 40,000 BTU gas fire table (Outland, Haiku, Cosi Fires) doubles as a feature piece.
Heat output by type: Tabletop propane: 10,000–15,000 BTU (warms a 5-ft radius circle). Standard tower heater: 40,000–48,000 BTU (warms a 15-ft diameter circle). Commercial tower: 50,000–60,000 BTU (warms a 20-ft diameter circle). Gas fire table: 30,000–60,000 BTU. Wood fire pit: 80,000–150,000+ BTU (most powerful, but uncontrolled). Electric infrared ceiling: 5,000–15,000 BTU per unit (targeted, directional).
Yes, with caveats. Electric infrared heaters: safe under any covered porch with no minimum clearance from combustible surfaces. Propane/natural gas heaters: require minimum 24–36 inches clearance from any combustible overhead surface and adequate ventilation. Never use open-flame propane heaters in enclosed screened porches without opening two screens for ventilation. Always follow manufacturer clearance requirements — they vary significantly by model.
Hourly operating costs: Propane standard tower (40,000 BTU): $1.50–$2.50/hour. Natural gas tower (40,000 BTU): $0.40–$0.80/hour. Electric infrared (1,500W): $0.15–$0.25/hour. Propane fire table (50,000 BTU): $1.80–$3.00/hour. Natural gas fire table: $0.50–$1.00/hour. For 40 evenings/year at 3 hours each: propane costs $180–$300/year; natural gas $48–$96/year; electric $18–$30/year (excluding installation costs).
For small apartment or condo balconies: electric heaters are the safest and most reliable choice (no propane fire code issues, no tank storage). Best options: freestanding electric infrared floor heater ($100–$300), tabletop electric heater ($40–$150), or wall-mount electric infrared ($150–$400). Check building rules first — most condos prohibit propane tanks on balconies. For a 50 sq ft balcony, a 1,500W electric heater provides comfortable supplemental warmth in temperatures above 45°F.
