Outdoor Electric Heaters

Electric patio heaters warm people and surfaces directly with infrared, which is why they keep working outdoors where a fan-forced heater loses its heat to the first breeze. This collection spans wall, ceiling, flush-mounted and portable models, in 120V plug-in and 240V hardwired versions, for covered porches through to fully exposed decks.

Why Infrared, and Not a Fan

Every heater in this collection is infrared. It warms people and surfaces directly, the way sunlight does, rather than heating the air around them. Outdoors that distinction is the whole ballgame: warmed air drifts away on the slightest breeze, while radiant heat crosses the gap and is absorbed by whoever is sitting in it. A fan-forced heater that performs well in a garage will disappoint on an open patio for exactly this reason, and it is why an infrared heater keeps working on a windy evening when nothing else does.

Compared with gas patio heaters, electric needs a circuit rather than a fuel line, mounts tight to a ceiling with minimal clearance, makes no noise and produces nothing to vent. Gas reaches higher outputs and covers more ground per unit. That trade, clearance and simplicity against raw output, is usually decided by the building rather than by preference.

Sizing by Wattage

Coverage tracks wattage closely, and manufacturers publish it as a footprint rather than a room size. Roughly, a single-element unit covers a small seating group, and doubling the wattage roughly doubles the area. Two things move the answer more than shoppers expect.

First, mounting position changes coverage, and several manufacturers publish separate figures for wall-mounted and overhead installation of the same heater. Second, published outdoor coverage is smaller than indoor coverage for the same unit, sometimes by a third or more, and a few manufacturers break it down further into enclosed, covered and fully exposed. Size from the outdoor figure, and expect to need more than one unit over a full seating group. Two smaller heaters spread across a space almost always beat one large one aimed at the middle of it.

120V or 240V

This is the decision that most often sends a project back to an electrician, so settle it before you choose a model. Lower-wattage heaters run on standard 120V, and some of those simply plug into an outlet, which makes them the practical answer when running a new circuit is not realistic. Higher-output models run on 240V, or 208V in many commercial buildings, and are hardwired to a dedicated circuit.

The two are not interchangeable. The heating element is matched to its voltage at the factory, so a 240V heater cannot be adapted to a 120V supply and a 120V unit will not simply run hotter on 240V. Order the version for the power you actually have, and check what else is already on that circuit.

Where It Mounts

Wall mounted is the most common, angled down over a seating area from a wall or post.
Ceiling and overhead suits a covered patio, pergola or gazebo, and puts the heat where nobody bumps into it.
Flush mounted recesses the housing into a soffit so only the face shows, which is the cleanest finish and has to be planned into the build.
Portable and free-standing needs no structure at all, and is the honest answer for a rental or a space with nothing to mount to.

Whichever you choose, the manual gives a recommended mounting height and a minimum clearance to the ceiling. Both matter: too low and the heat concentrates into a hot spot, too high and it spreads out and feels weak.

How Much Weather It Can Take

Outdoor rating is not one standard, and the difference decides where a heater can go. Many units carry an IPX4 rating, meaning the housing resists splashing water from any direction, which suits a porch, a soffit or a pergola with a solid roof. A smaller group carries IP65 or IP66, adding dust-tightness and protection against water jets, and those are the ones to specify for a fully exposed deck or a poolside post. If the location gets real weather, start with weatherproof outdoor electric heaters and read the rating on the specific model.

What to Settle Before You Order

Available power, including whether a dedicated circuit exists and what it can carry alongside everything else.
The weather rating for the exact spot, since a covered porch and an open deck are different problems.
Mounting height and clearance, which the manual specifies and which controls both safety and coverage.
Controls. Some models switch on the wall, some accept a dimmer or a smart control, and those are wired in at installation rather than added afterward.
How many units the space needs, worked out from the outdoor coverage figure rather than the indoor one.

For a restaurant patio, hotel terrace or anywhere running nightly, start with commercial-rated equipment. For the full range of outdoor heating across every fuel, see patio heaters.

Frequently Asked Questions about Outdoor Electric Heaters

Do electric patio heaters actually keep you warm outdoors?

Yes, provided it is an infrared heater, which every model here is. Infrared warms people and objects directly rather than heating the air, so the warmth is not carried away the moment a breeze picks up. You feel it almost immediately, the way you feel sun coming through a window on a cold day. What will disappoint you outdoors is a fan-forced or convection heater, which works by warming air and needs an enclosed space to do it. That difference, not brand or price, is the single best predictor of whether an outdoor heater will satisfy you.

How many watts do I need for my patio?

Work from the manufacturer's published coverage footprint rather than your patio's total square footage, because you are heating the seating area, not the whole space. Coverage scales closely with wattage: doubling the wattage roughly doubles the area covered. Two adjustments matter. Use the outdoor coverage figure, not the indoor one, since the same heater covers meaningfully less area outside and some manufacturers publish separate numbers for enclosed, covered and fully exposed locations. And check whether the figure assumes wall or overhead mounting, because several manufacturers publish different numbers for each. For a full seating group, two smaller units spread across the space give more even warmth than one large unit aimed at the middle.

Can an electric patio heater plug into a regular outlet?

Some can. Lower-wattage models run on standard 120V and a number of those are plug-in, which makes them the practical choice when adding a circuit is not realistic. Higher-output models run on 240V, or 208V in many commercial buildings, and must be hardwired to a dedicated circuit by an electrician. The important thing to know before ordering is that the heating element is matched to its voltage at the factory: a 240V heater cannot be adapted to a 120V outlet, and a 120V unit does not simply run hotter on 240V. Confirm the voltage of the exact version you are buying, and check what else is already drawing on that circuit.

Are electric patio heaters cheaper to run than gas?

Per unit of heat delivered, gas is usually cheaper to run, and gas reaches higher outputs so it covers more ground per heater. Electric wins on the costs around the heat: no fuel line to run, no cylinders to swap or store, no ventilation or clearance requirements to design around, and effectively no maintenance. It also switches on instantly at full output, which changes how you actually use it. Because infrared heat is felt immediately, electric heaters get turned on when people go outside and off when they leave, instead of running to bring a space up to temperature. To estimate your own cost, divide the wattage by 1,000 to get kilowatts, then multiply by your utility rate per kilowatt-hour and the hours you expect to run it.

Can the same heater be used indoors?

Many models in this collection are rated for both, and they are a common answer for a garage, a workshop, a sunroom or an enclosed porch, where infrared heats the people working rather than trying to warm a large volume of air. Two things to check on the specific model. First, confirm the manual lists indoor use, because outdoor rating alone does not imply it. Second, note that published indoor coverage is larger than outdoor coverage for the same unit, so a heater sized for a patio will feel stronger inside. A few of the highest-voltage commercial variants are marked for commercial use only, and those exclusions are stated in the manual for that model.

What is the difference between an electric patio heater and an electric fireplace?

They are different appliances that heat by different physics, and outdoors the difference decides whether anyone feels anything. An electric patio heater is infrared: it radiates, and the heat is absorbed directly by people and surfaces. An electric fireplace uses a fan-forced coil, which warms the air passing through it. Indoors that works well. Outdoors the warmed air simply drifts away, which is why an outdoor electric fireplace is bought for how it looks, not for warmth. If you want both, the combination that actually works is a fireplace as the focal point plus overhead heaters covering the whole seating group, so the far chairs are comfortable too.
