Outdoor heat is a tradeoff between reach, fuel, and wind. Propane patio heaters cover the biggest open spaces, while electric infrared units make more sense on covered patios with a nearby outlet.
Pellet heaters come up in searches, but they are far less common for patios than propane and electric models, so this guide focuses on the heaters people actually buy for winter seating, backyard dinners, and drafty semi-covered spaces.

How To Choose An Outdoor Heater For Winter Comfort
Three things decide whether an outdoor heater works for you: heat output, fuel type, and where you’ll put it. Open patios lose warmth fast to wind and cold air, so bigger BTU numbers matter more than trim or paint. A 40,000 to 46,000 BTU propane heater throws heat in a 9- to 15-foot radius and keeps seating areas comfortable even when the temperature drops into the 30s. Electric infrared heaters work well under a covered patio or pergola where you’ve got an outlet within cord reach, but they top out around 1,500 watts—enough for a couple of chairs, not a whole deck.
Propane patio heaters are the best heater for outdoor comfort all winter long when you need to warm an open seating area. They light with a push-button igniter, run from a standard 20 lb propane tank that tucks into the base, and roll on wheels. The Amazon Basics 46,000 BTU model and similar tower designs stand about 7 feet tall and radiate heat downward and outward, warming people instead of empty air. Electric infrared units like the DR. INFRARED HEATER portable model plug into a 120 V outlet and heat a smaller zone without fumes, but they need a covered spot to keep rain and snow off the element.
Indoor-only electric fireplaces—including wall-mounted and recessed models—are not rated for outdoor use. Rain, humidity, and temperature swings damage the electronics and create shock and fire risks. If you want electric heat outdoors, buy a heater with an outdoor or indoor/outdoor rating and an IP weather-resistance code on the spec sheet.
Tabletop propane heaters sit on a patio table and warm one or two people seated close by. They run from a small 1 lb propane canister and put out 10,000 to 15,000 BTU, enough for a bistro setup but not a six-seat dining table or a deck with multiple conversation areas.
| Fuel type | Heat output | Best placement | Reach |
|---|---|---|---|
| Propane (tower) | 40,000–46,000 BTU | Open patio, deck | 9–15 ft radius |
| Electric infrared | 1,500 W (5,100 BTU) | Covered patio, near outlet | 6–8 ft |
| Propane (tabletop) | 10,000–15,000 BTU | Small table, balcony | 3–5 ft radius |
Outdoor Pellet Heater Vs Gas Heater
An outdoor pellet heater is a fuel-burning appliance that uses wood pellets to generate heat, with a hopper that feeds pellets into a burn pot and a vent or chimney that exhausts combustion gases. Pellet heaters need a steady supply of bagged pellets, a dry place to store them, and regular ash cleanout—daily or weekly depending on burn time. Most are freestanding stoves designed for workshops, garages, or three-season rooms, not patio furniture arrangements.
Patio buyers more often end up with propane or electric infrared heaters because those are easier to find, simpler to light, and more common in retail listings. A propane patio heater lights with a push of a button, runs from a 20 lb tank you swap at the gas station or hardware store, and rolls wherever you need it. A pellet heater requires startup kindling or gel, takes 10 to 15 minutes to reach full heat, and weighs enough that moving it across a deck is a two-person job.
Wood and pellet appliances must follow the venting and clearance distances required by the manufacturer’s listing and local building code. That means a chimney or vent pipe run, non-combustible flooring underneath, and clearances to walls, furniture, and overhead structures—often 36 inches or more on each side. Never improvise a pellet stove setup for a patio crowd without checking those numbers and getting the required permit if your jurisdiction requires one.
If you’re comparing fuel costs, propane patio heaters burn about 2 lb of propane per hour at full output—roughly $3 to $4 an hour at current propane prices. Wood pellets cost less per BTU, but the upfront price of a pellet stove runs $800 to $2,500, and installation adds chimney and venting expense. Propane tower heaters start around $150 and need no installation.
How Long A 20 Lb Tank Lasts
A 20 lb propane tank holds about 430,000 BTU of usable energy, so a 46,000 BTU outdoor gas heater running at full output will burn through it in roughly 9 hours. That’s the math on paper. In practice, you’ll adjust the flame down when the air warms up or guests move closer, and most patio heaters let you dial back to half or a third of rated output.
Electric infrared heaters pull 1,500 W, the maximum for a standard outlet. Run one for 8 hours and you’ve used 12 kWh; at 17 cents per kWh that’s about $2.04 a night. Propane costs vary, but refilling a 20 lb tank typically runs $15 to $25, so those nine full-output hours work out to around $1.65 to $2.75 per hour.
| Heater | Watts | Per hour | Per day (4 h) | Per month (10 days) |
|---|---|---|---|---|
| 1,500 W electric patio heater | 1,500 W | 26¢ | $1.02 | $10.20 |
Wind steals more heat than most spec sheets admit. A 15 mph breeze can cut the effective radius of a patio heater nearly in half, so you’ll crank the dial higher and burn fuel faster. Thermostat cycling helps if your model has one, but most outdoor gas heaters run at whatever setting you choose until you turn the knob or the tank empties.
Clearance, CO Risk, And Mounting Rules
Outdoor gas heaters belong outdoors or in spaces the manufacturer explicitly allows, with the clearances the manual requires. Most freestanding propane patio heaters need 3 feet from walls and overhangs and at least 80 inches of overhead clearance; tabletop models often ask for 30 inches above and 2 feet to the sides. Check the label on your unit.
Propane heaters produce carbon monoxide, a colorless, odorless gas that kills. Use them only where the manual and local code allow, and never in an enclosed garage, tent, or any space without adequate ventilation. If you’re heating a three-sided porch or a barn with open walls, confirm the model is rated for that application and install a battery-powered CO alarm within 15 feet.
Electric patio heaters plug straight into a wall outlet, never an extension cord or power strip. A 1,500 W unit draws 12.5 amps, close to the 15-amp limit on most household circuits, so don’t run other high-draw appliances on the same circuit while the heater is on. Outdoor-rated models carry a weatherproof plug and a GFCI, but you’ll still want a covered outlet or a location under an eave.
Heaters for an outdoor barn with no electricity leave propane, kerosene, or diesel as your options. Propane cabinet heaters and kerosene forced-air units will heat a large space, but both need ventilation and a CO alarm. Never bring a torpedo or construction heater into a barn where people or animals spend time unless the manual confirms it’s rated for that use and you can meet the fresh-air requirements.
Which Pick Fits Your Space
Open patios and larger seating areas do best with the Amazon Basics 46,000 BTU propane heater because its 9-foot heat radius covers a wide circle, the wheels let you roll it between spots, and a standard 20 lb tank keeps it running for about 9 hours at full output. That’s enough BTU to feel warm on a cold night without standing right next to the unit. Smaller covered patios, garages, and workshops suit the DR. INFRARED HEATER wall or ceiling mount better—radiant infrared heat warms people and objects directly the moment you switch it on, and it runs quietly without a flame.
Tabletop propane heaters work for a small bistro table or two chairs pulled close, but they won’t heat a whole deck or barn. Heat output tops out around 11,000 BTU on most tabletop models, and the radius shrinks to about 3 feet where you’ll feel warmth.
Comfort Glow is a brand that produced outdoor gas and portable propane heaters, made by World Marketing of America. These models are no longer widely available, and most product lines haven’t been updated for years. The search for a 5000but powerful haet large flame for outdoor warmth focuses on two things: a visible flame that mimics a fire and enough heat output to keep you comfortable outside in cold weather. The Amazon Basics propane heater shows the flame through a quartz glass tube and delivers 46,000 BTU to warm a patio area. Indoor electric fireplaces like the R.W.FLAME 50 inch create a strong flame effect but are meant for indoor use only, not outdoor patios.
