There is a familiar point in almost every cool-weather patio evening. Dinner is finished, the light has gone blue, somebody pulls a jacket tighter and another person says, “It’s getting a little chilly out here.” Ten minutes later the patio is empty.
A good heater changes that. Not by turning the backyard into a living room — that is an unrealistic standard for any outdoor appliance — but by putting useful warmth where people are actually sitting. Once you start looking closely, propane, electric, natural gas and wood-pellet heaters solve that problem in very different ways.
I would not choose among them by BTU rating alone. Outdoor heat is slippery. Warm air rises, wind steals it, and a tall heater can make your face warm while your legs still feel like they are sitting in another climate. Placement, radiant heat, fuel logistics and the way you use the patio all matter more than most product pages admit.
Electric vs. Propane Patio Heater: Which Is Better?
If you are comparing an electric vs propane patio heater, the best choice usually comes down to where the heater will be used. Electric infrared heaters are especially strong for covered patios and fixed seating areas because they provide targeted radiant heat without a propane tank. Propane heaters are more portable and can deliver strong heat in open patio areas without requiring a dedicated electrical circuit.
| Factor | Electric patio heater | Propane patio heater |
|---|---|---|
| Best location | Covered patios and fixed seating areas | Open patios and flexible seating layouts |
| Heat style | Targeted radiant heat | Broad heat from a freestanding burner |
| Portability | Usually fixed or limited by cord/circuit | Easy to move if the unit is freestanding |
| Fuel / power | No tank; higher-output models may need a dedicated circuit | Requires propane-cylinder refills or exchanges |
| Covered-patio use | Often the easier option when installed to required clearances | Must meet side and overhead clearance requirements |
| Convenience | Switch on and off; no fuel handling | No electrical installation, but tanks need monitoring |
My quick take: for a covered patio with predictable seating, I would usually start with electric infrared. For an open patio where portability matters, propane is often the more flexible choice. The rest of this guide explains why—and where natural gas and wood-pellet heaters fit.
First, Stop Thinking Only About BTUs
BTUs are useful, but they can become a false sense of precision outdoors. A heater can have a large input rating and still feel disappointing if the warmth is concentrated high above you or blown away before it reaches the seating area.
That is why radiant heat matters. Instead of depending entirely on warming the surrounding air, radiant energy warms people and nearby surfaces more directly. You notice the difference on a breezy night, and especially when you are sitting rather than standing.
Timber Stoves makes this point with thermal imaging that compares one of its pellet heaters with a conventional mushroom-style propane heater. The company’s images show a much taller warm zone along the pellet heater, while the propane heater concentrates much of its visible heat around the top reflector. That is manufacturer-supplied evidence, not an independent laboratory test, but it illustrates a real design difference worth understanding.
Propane: Familiar, Portable and Easy to Understand
Propane remains the default patio-heater fuel for a reason. The equipment is familiar, the tanks are available almost everywhere, and you can roll the heater to whichever corner of the patio needs help.
A full-size mushroom-style propane unit commonly lands around the 40,000-BTU class. For an occasional Saturday-night patio, that may be exactly enough. There is no installation project and almost no learning curve. If you can operate a gas grill, the basic routine feels familiar.
The weakness is just as familiar. Much of the burner hardware sits several feet above the people you are trying to warm. Stand close and your shoulders can feel great. Sit a few feet away in a light breeze and the experience changes quickly.
And then there is the tank. Anyone who uses propane regularly eventually develops the habit of lifting the cylinder before company arrives. And, as anyone who grills often knows, the tank always seems to get light at the least convenient time.
Electric Infrared: The Quiet Overachiever
Electric heaters rarely create the same visual drama as a fire, but that is not what they are trying to do. Their appeal is precision. Mount a good infrared unit over a dining table or along the wall of a covered patio and it can put warmth exactly where people sit.
No tank. No ash. No fuel storage. No flame to light. Press a switch and it is working.
That simplicity is especially attractive under a roof where seating does not move very much. A correctly positioned infrared heater can feel more effective than its modest BTU equivalent suggests because it is not trying to heat the whole yard.
The catch is electrical capacity. A basic 1,500-watt plug-in unit is easy to accommodate but relatively modest in output. Larger heaters may need a dedicated circuit or higher voltage, which turns a simple purchase into an electrical project. Before buying a pair of high-output heaters, I would check the panel and circuit requirements first, not after the boxes arrive.
Natural Gas: Excellent When the Patio Is Already Set Up for It
Natural gas solves propane’s most annoying problem: you do not run out halfway through dinner. If a properly sized gas line already reaches the patio, a natural-gas heater can be economical and wonderfully low-fuss.
But it gives up portability. The gas connection largely decides where the heater lives. Adding a new outdoor gas line can also erase much of the cost advantage if trenching, permits or professional plumbing are required.
I like natural gas most when the infrastructure already exists. I am less enthusiastic about designing the entire patio around it simply to avoid filling propane tanks.
Wood Pellets: The Interesting One
This is the category that surprised me most when comparing the four approaches, because a good pellet patio heater is doing two jobs at once. It is a heater, certainly, but it is also a visible fire feature.
That distinction sounds cosmetic until you picture the way people actually use a patio. Nobody gathers around a wall-mounted electric heater to watch it glow. A tall flame behind glass becomes part of the evening. Chairs gradually drift toward it. Conversation tends to follow.
Timber Stoves has built its outdoor line around that idea. Its heaters use a gravity-fed pellet system and natural draft, so there is no electric auger or blower required. Pellets feed from a rear hopper into the burn area as the fuel below is consumed. The tall chimney creates the draft that keeps combustion moving. The result is a portable pellet heater that does not need to be plugged in.
Why that matters in actual use
You get real flame and strong radiant heat without dragging an extension cord across the patio. There are also fewer powered mechanical components than you would find in a conventional indoor pellet stove. The tradeoff is simply that it behaves more like a real fire appliance: you handle fuel and occasionally clean ash. For people who enjoy the flame and atmosphere, that small amount of involvement may actually feel appropriate.
A Closer Look at Timber Stoves
Timber Stoves currently offers several outdoor pellet heaters ranging from a tabletop Scout to full-size freestanding models. The company manufactures its heaters in Oregon and uses stainless steel construction on the full-size units. Current published ratings include roughly 72,000 BTU for the Lil’ Timber, 85,000 BTU for the Ranger, and 90,000 BTU for the Big Timber and Revere. Published maximum heating radii run from about 10 feet on the Lil’ Timber to about 12 feet on the larger models.
Those are substantial ratings, but the specification I care about more is the shape of the heat. Timber’s full-size heaters place a long, visible flame inside a tall body rather than hiding a relatively compact burner under a top reflector. That helps explain why owners often describe the warmth as more noticeable from head to toe.
Timber Stoves models worth knowing
| Model | Published output | Hopper / burn-time note | Best fit |
|---|---|---|---|
| Scout | Tabletop model | Compact fuel capacity | Smaller seating areas and tabletops |
| Lil’ Timber | 72,000 BTU | 12.5-lb hopper; about 1.5 hr published burn time | Patios where size and heat need to stay balanced |
| Ranger | 85,000 BTU | 20-lb hopper | Large patio, round-barrel styling |
| Big Timber | 90,000 BTU | 20-lb hopper; about 2 hr published burn time | High-output entertaining spaces |
| Revere | 90,000 BTU | 25-lb hopper | Longer sessions and a larger viewing area |
What I Like About the Pellet Approach
1. The heat starts lower
This is the practical advantage I keep coming back to. When people are sitting outside, warming the lower half of the body matters. A tall radiant fire has an intuitive advantage over a heater whose hottest hardware is concentrated near the roofline.
2. The flame is part of the patio
An outdoor space feels different with a visible fire. That is subjective, but it is not trivial. We spend money on landscaping, lighting, furniture and fireplaces because atmosphere matters. If the heater can contribute to the look of the space instead of merely occupying it, that has value.
3. No electricity is required on Timber’s gravity-fed designs
The company’s system relies on pellet gravity feed and chimney draft rather than an electric auger and fan. That means the heater can sit where it makes sense instead of where an outlet happens to be.
4. Pellet fuel is compact and easy to store
A bag of pellets is less awkward than keeping multiple propane cylinders around, though it does need to stay dry. Timber notes that pellets are made from sawmill by-product and markets them as a lower-carbon fuel option.
Which Heater Is Cheapest to Run?
There is no honest nationwide answer because electricity, natural gas, propane and pellet prices vary by region and season.
Timber Stoves currently publishes a normalized comparison that puts natural gas at about $0.50 per hour, wood pellets around $0.63, electric around $1.40 and propane around $2.00 under its stated assumptions. Those figures are useful for seeing the company’s argument, but I would not use them as a personal operating budget without plugging in local fuel prices.
The better way to think about cost is this: propane usually wins on low initial commitment; electric can be economical when you heat a small, targeted zone; natural gas can be inexpensive once the line exists; and pellets can deliver a lot of heat per dollar if bagged fuel is inexpensive where you live.
Wind Changes Everything
Outdoor heater reviews often happen on calm evenings. Backyards do not.
If your patio is consistently windy, adding a windbreak can improve comfort more than simply buying a larger heater. A partial wall, screen, landscaping or thoughtfully placed furniture can prevent warm air from disappearing instantly.
Freestanding heaters also need stability. Timber sells a weighted base plate for its full-size units, which is a sensible option in exposed locations. But a heavy base is not permission to operate any heater in unsafe winds. If the weather makes you wonder whether the heater should be running, that is usually your answer.
Covered Patio? Read the Clearance Requirements First
This is the section I would read before falling in love with a particular model.
Combustion heaters need clearance from ceilings, walls, furniture and combustible materials. Electric infrared heaters are often easier to integrate into covered structures, but they still have manufacturer-specified mounting distances.
Do not use a product photo as a clearance guide. Download the current manual for the exact model and plan the heater around those dimensions.

The Patio-Use Test
| Your situation | The heater I would look at first | Why |
|---|---|---|
| Small covered patio with fixed dining table | Electric infrared | Quiet, targeted heat and almost no maintenance |
| Rental or occasional-use patio | Propane | Low commitment, movable and easy to replace |
| Permanent outdoor kitchen with gas already nearby | Natural gas | No cylinders and very convenient once installed |
| Large open patio used for entertaining | Wood pellet | Strong radiant heat plus a visible focal-point fire |
| Patio where atmosphere matters as much as raw heat | Wood pellet | The heater becomes part of the evening rather than background equipment |
| You want absolutely no fuel handling | Electric | Nothing to refill, store or clean up |
So, Which One Would I Buy?
For a compact covered patio where I sat in the same chair every evening, I would probably install electric infrared heat. It is too convenient to ignore.
For occasional use or a patio where the heater has to move around, propane remains hard to beat for simplicity.
If a natural-gas stub were already waiting beside the patio, I would take advantage of it rather than invent another fuel-storage chore.
But for a patio designed around entertaining — the sort of place where the heater will be visible and people will actually gather around it — I would put a wood-pellet heater near the top of the list. In that setting, the combination of strong radiant heat, a tall visible flame and no electrical connection makes a lot of sense.
And among the pellet options I looked at, Timber Stoves deserves a particularly close look. The designs are purpose-built for outdoor heating, the larger models publish serious output numbers, the flame is enclosed, and the gravity-fed system avoids the powered augers and fans normally associated with pellet appliances. That is a genuinely different approach rather than another cosmetic variation on the mushroom heater.
I would still go into it knowing that pellets mean a little participation. You load them. You light them. You clean the ash. For homeowners who like the feel of a real fire, that little bit of participation can be part of what makes the heater enjoyable — closer to an outdoor fireplace than an appliance on a pole.
The bottom line
Choose electric for effortless targeted heat, propane for portability, natural gas for a permanent low-fuss setup, and wood pellets when you want the heater to contribute to the entire patio experience. The best choice is the one you will actually use on the evenings when everybody else is ready to go inside.
Before You Buy
| Check | Why it matters |
|---|---|
| Actual seating distance | Heating radius is more useful than raw output if the chairs sit outside the effective zone. |
| Wind exposure | Wind can make a powerful heater feel weak and can create safety concerns. |
| Overhead clearance | Especially important under pergolas, awnings and covered patios. |
| Fuel storage | Keep propane cylinders stored safely and wood pellets dry and protected from moisture. |
| Electrical capacity | High-output electric heaters may require dedicated circuits or higher voltage. |
| Storage and weather protection | Pellets must stay dry; portable heaters also benefit from covers and protected storage. |
| Children and pets | Hot surfaces and traffic paths matter just as much as published clearances. |
