Wall mounted
Wall mounted patio heaters, and the rating that decides
Once a heater is bolted to an exterior wall it lives outdoors permanently. The specification that matters most is the one most listings do not publish.
For a permanently mounted outdoor heater the specification that matters most is the published IP rating: IP35 handles rain and dust, IP55 handles water directed from any angle. Output is fixed at 1,500 W across the category, so weather rating, mounting and aim are the real choices.
What an IP rating actually tells you
IP is a two-digit code. The first digit is protection against solids, the second against water. IP35 means protected against tools and thick wires, and against spraying water. IP55 means dust-protected and protected against low-pressure water jets from any direction.
For a heater on a sheltered porch ceiling, IP35 is comfortably sufficient. For a heater on an exposed wall where wind drives rain sideways at it, IP55 is the one to want. And for a heater with no published rating at all, the honest position is that you do not know — which is fine under cover and a gamble in the open.
Quick picks
Ranked for fit, not for hype. Output is the maker’s published figure; reach is computed from it or from the maker’s own radius claim, and the table says which. Tap a row for the full write-up, or go straight to the listing.

Top pick · The wettest exposed spot
Star Patio ZHQ1530 Wall-Mounted Electric Infrared Patio Heater
IP55 is the highest published ingress rating in this roundup, which makes it the one to mount where rain actually blows in sideways. Everything else about it is a standard 1,500 W infrared unit.
- Fuel
- Electric
- Output
- 1,500 W = 5,118 BTU/h
- Reach (computed)
- 256 sq ft · 9.0 ft radius
- Cost per hour
- $0.28
What works
- IP55 means dust-protected and rated against low-pressure water jets from any direction — a genuine step above the IP35 units
- The maker explicitly positions it for gazebo use, which is the enclosure where electric is the only correct answer
- Remote control on a wall-mounted heater is not a luxury; the unit is above head height and out of reach by design
What does not
- The listing publishes no coverage figure, so every reach number we show for it is our own arithmetic
- Wall mount only — there is no floor-standing option in this model
- 1,500 W, like everything else that plugs into a wall

Who it is for
An exposed wall on a gazebo, porch or balcony where weather gets at the unit and you still want electric heat.
What it is not for
Anywhere you need to move it, and any space large enough to need several thousand BTU rather than five thousand.

2 · Leaving outside all year
Heat Storm Tradesman HS-1500-OTR Outdoor Infrared Quartz Heater
The one electric unit here with a published IP rating, which is the difference between a heater that survives a wet winter mounted outdoors and one that is a warranty claim waiting to happen.
- Fuel
- Electric
- Output
- 1,500 W = 5,118 BTU/h
- Reach (computed)
- 256 sq ft · 9.0 ft radius
- Cost per hour
- $0.28
What works
- A published IP35 rating. Almost nobody in this category publishes an ingress rating at all, and mounting an unrated electric heater outdoors is a gamble you cannot price
- The maker publishes its own BTU figure (5,200), which is within a rounding error of the 5,118 our watts-to-BTU conversion gives — a company doing its own arithmetic honestly
- Wall or ceiling mount puts the heat above head height where a radiant beam belongs
What does not
- IP35 is splash-and-dust protection, not immersion — it survives weather, not a hose or standing water
- Fixed mounting means fixed aim. Get the position wrong and there is no adjusting it from the chair
- Same 1,500 W ceiling as every other plug-in electric heater
| Published specification | |
|---|---|
| Rated power | 1,500 W at 120 V |

Who it is for
A permanently mounted heater on a pergola, porch ceiling or exterior wall that you never want to take down and store.
What it is not for
Portability, and any open patio with no structure to mount to.
3 · Wind, and anywhere with a roof
Dr Infrared Heater Carbon Infrared Patio Heater, 120 V / 1500 W
Radiant heat that a breeze cannot blow out, on a plug. 1,500 W is only 5,118 BTU/h, which sounds like nothing next to a propane tower and lands far more of itself on you.
- Fuel
- Electric
- Output
- 1,500 W = 5,118 BTU/h
- Reach (computed)
- 256 sq ft · 9.0 ft radius
- Cost per hour
- $0.28
What works
- Infrared warms objects, not air, so it is the only heat that survives a breeze — this is the single reason wind changes the whole buying decision
- No combustion means no flue gas, which is what makes it legal and sensible on a screened porch where propane is not
- Three settings matter more than they sound: 900 W costs a third less to run and is enough most evenings
What does not
- 1,500 W is 1,500 W. Nothing at this wattage heats faster than anything else at this wattage; the differences between electric heaters are beam shape and build, not power
- It heats what it points at. Step out of the beam and you are cold immediately — this is a fundamentally different experience from a tower
- A 120 V plug-in unit is capped by your circuit, not by the maker. See why 1,500 W is the ceiling

Who it is for
A covered patio, pergola or screened porch where you can mount it overhead and point it at where people sit, and anywhere wind ruins a flame.
What it is not for
A big open patio with nowhere to mount it. Radiant heat needs a line of sight and a place to hang from.
What we would skip
A list with no losers is a list nobody edited. These are the choices we would actively steer you away from, and why.
Mounting anything without a published IP rating on an exposed wall
This is the whole point of the page. An electric appliance bolted where rain reaches it needs an ingress rating you can read. IP35 handles weather; IP55 handles weather that arrives sideways. No published rating means no way to price the risk.
Mounting before you have settled the aim
A wall-mounted heater is fixed. Spend one evening with the unit on a stand or held in place before drilling, and put it where the beam actually crosses the chairs. The most common complaint about mounted heaters is not output, it is aim.
Sharing the circuit
1,500 W continuous wants a circuit largely to itself. Mounting a heater on the same spur as a garage freezer or an outdoor outlet run is how you discover the 80 percent continuous-load rule the hard way.
The mounting checklist
- Height: seven to nine feet, angled down. Lower and the beam hits people in the head rather than the body; higher and it spreads too thin.
- Aim across the seating, not at the middle of the patio. Radiant heat covers what it points at, so point it at chairs.
- Clearance above. Fire Sense publishes 12 to 24 inches of overhead clearance for electric units. Under an eave, check it before you drill.
- A dedicated, GFCI-protected outdoor circuit. 1,500 W continuous on a shared spur is a tripping breaker waiting to happen.
- Fix into structure, not into cladding. A 10 lb unit on a lag screw into siding will eventually find the ground.
How we picked
- Published IP rating first. A permanently mounted outdoor appliance either has one or the listing is silent, and that silence is information.
- Mounting hardware included, and what it mounts to. Wall-only, ceiling-only and both are three different products.
- Remote control treated as functional, not luxury. A heater above head height is out of reach by design.
- Aim considered. A fixed heater aimed at the wrong place cannot be nudged from a chair, so the adjustment range matters at purchase time.
What we did not do
Everyone in this category says they tested twenty heaters. We have not tested any, and we say so. What we do instead: compile the published specs, compute the electrical and gas load from them, cite the maker’s own manual, and show the arithmetic so you can check it. The full method, including how to challenge a figure.
Common questions
How high should a wall mounted patio heater be?
Seven to nine feet, angled down toward the seating. Lower puts the beam at head height; higher spreads it too thin to feel. Also check your model's published overhead clearance — Fire Sense quotes 12 to 24 inches for electric units.
Do wall mounted patio heaters need a special circuit?
They need an outdoor-rated, GFCI-protected circuit, and a 1,500 W continuous load should largely have it to itself. Electrical code caps continuous loads at 80 percent of the branch rating, which is 1,440 W on a standard 15-amp circuit.
What IP rating do I need for an outdoor heater?
IP35 is enough for a sheltered position under an eave or porch ceiling. IP55 is what you want where wind-driven rain reaches the unit directly. If a listing publishes no rating at all, treat it as suitable for sheltered mounting only.
