Outdoor Heating in Wind | Infrared Comfort Guide

Outdoors, wind is the #1 reason heaters “don’t work”, even with high wattage. For real, felt warmth (terraces, pergolas, hospitality), you need to understand what wind removes and how to design an installation that stays effective.

1) Why wind cancels most outdoor heating

Wind is not only a sensation — it is a loss accelerator. Any system that mainly heats air (convection) struggles outdoors because warm air is immediately replaced by cold air.

Convection (heated air)

Wind carries warm air away
The air volume is effectively “infinite”
Comfort fluctuates constantly

Radiant heat (people & surfaces)

Wind impacts perceived warmth far less
You heat a zone, not the whole environment
Comfort is faster and more stable

Key idea: in windy outdoor spaces, comfort comes first from infrared radiant heat, then from smart zoning and correct geometry (height, angle, distance).

2) Not all “windy terraces” are the same

Before comparing products, identify your real scenario:

A) Fully open terrace (direct exposure)

You need focused radiation and often multiple heat points. Priority: heat the occupied zone (table/lounge), not the whole area.

B) Pergola / canopy (semi-sheltered)

Great conditions for infrared: aim for even coverage and fine aiming. Ceiling/structure mounting is usually ideal.

C) Partly enclosed (screens, blinds, side panels)

Comfort improves dramatically because losses drop. You can often use fewer units and gain better control (zones/dimming).

3) The pro method: “zone + aiming + radiant density”

Outdoors, you don’t optimise “watts” first — you optimise radiant density on the occupied zone. Use this order:

Define the occupied zone (table, lounge, queue, service)
Set mounting height per zone
Aim into the zone (often 30–45° depending on height/distance)
Open spaces need multiple points rather than one “big” heater

Common mistake: one powerful unit, mounted too high and too wide. Result: warm floor/air, not warm people.

4) Anti-wind checklist

Do

Zone first: 1 heater = 1 usable zone
Keep height under control
Aim at people, not empty space
Open terraces: plan multiple heat points
Reduce airflow when possible (screens/blinds)

Avoid

“W/m2” sizing without zones
Mounting too high “to cover more”
Glare / harsh visible glow
Heating non-occupied areas
Ignoring prevailing wind direction

5) FAQ

Does infrared really work in windy conditions?

Yes. Infrared warms people and surfaces directly, so wind disrupts perceived warmth far less than convective heating.

What if the terrace is a “wind tunnel”?

Work with smaller zones, add more heat points, lower mounting height where possible, aim precisely, and reduce airflow with side protection.

Why doesn’t “more watts” solve it?

Because comfort depends on radiant density and aiming. Too high or too diffuse means energy goes where you don’t need it.

Note: follow manufacturer safety clearances, the right IP rating, and local electrical rules.
