Outdoors, installation determines comfort. A premium heater placed poorly can underperform, while a correct layout maximises effective coverage and reduces waste.
1) Define the occupied zone (before talking watts)
Dimensioning starts from where people actually sit or stand (dining, lounge, service area), not from total surface.
- Where are people stationary for 10–30 minutes?
- What is exposed to prevailing wind?
- What mounting height is available under a pergola / overhang?
2) Recommended mounting heights
Residential
1.8–2.2 m: denser perceived warmth, easier targeting.
Hospitality / larger terraces
2.4–3.0 m: safe coverage with better uniformity on larger zones.
Above these heights, radiant intensity drops quickly: prefer multiple points and better orientation rather than “more watts”.
3) Wall vs ceiling vs pergola structure
| Mounting | Strength | Best use |
|---|---|---|
| Wall | Precise targeting | Dining table / fixed seating zone |
| Ceiling | More uniform coverage | Pergola / overhang / circulation areas |
| Pergola structure | Stable, discreet, protected | Premium projects, frequent use |
4) Aiming: the #1 mistake
Infrared must aim at the occupied zone. Typical recommendation: 30–45° tilt toward the seating (depending on height).
If you heat empty floor or outside the zone, comfort drops sharply while consumption stays the same.
5) IP ratings & electrical safety
- IP44 minimum for sheltered outdoor, higher if exposed.
- Respect manufacturer safety clearances (materials, fabrics, ceiling).
- A protected circuit is recommended for higher power installations.
Always follow local electrical rules and manufacturer instructions (clearances, mounting, ventilation, cable sizing).
FAQ
Yes if you can mount it correctly and ensure compliant wiring; performance still depends mostly on geometry (height/angle/zone).
Recommended for higher power: it improves safety and avoids performance issues related to wiring and load sharing.
