“Open terrace”, “pergola”, “canopy”, “partly enclosed” often describe very different physics. The right choice depends on real openness and on your occupied zones—not on a single “most powerful” unit.
1) Classify your terrace in 2 minutes (4 levels)
| Level | Description | Winning strategy |
|---|---|---|
| 1. Fully open | No roof / very high roof, direct wind | Strict zoning + multiple heat points + focused radiation |
| 2. Under canopy/pergola | Roof present, sides open | Even coverage + precise aiming |
| 3. Partly enclosed | Screens/panels on 1–2 sides | Lower losses + more stable comfort + zone control |
| 4. Enclosed | Veranda-like (near indoor) | “Indoor” comfort logic + moderate output + control |
2) The most common mistakes
Mistake #1: sizing “per m2”
A terrace is rarely one zone. A table, a lounge and a service path are three uses—often three zones.
Mistake #2: mounting too high
Higher mounting can reduce radiant density. You “cover more”, but warmth becomes less felt.
Mistake #3: poor aiming
A radiant heater must “see” the occupied zone. If you heat empty space, you lose comfort fast.
3) Pro solutions by terrace type
Fully open terrace (exposed)
- Split the space into zones and design zone-by-zone
- Keep height under control; aim into the occupied area
- Use multiple heat points rather than one “big” unit
Pergola / canopy (semi-sheltered)
- Ceiling/structure mounting for even coverage
- Fine aiming towards seating
- Long spaces: split into 2–3 zones
Partly enclosed (screens/panels)
- Lower losses → heat feels stronger
- Often fewer units needed; better controllability
- Zone control/dimming recommended (pro)
Enclosed (veranda-like)
In near-indoor conditions, you can plan “room comfort” while keeping the direct feel of radiant heat.
- Moderate output, even distribution
- Control (thermostat/controller) recommended
- Avoid local overheating
4) Quick checklist before buying
Questions
- What is the truly occupied zone?
- What mounting height is available?
- Where does wind typically come from?
- How many zones (table/lounge/path)?
- Can you add side protection?
Target result
- Felt warmth in 1–3 minutes
- Stable comfort despite airflow
- No harsh glare
- Zone control (pro) or simple use (home)
5) FAQ
Does partial enclosure really make a big difference?
Why is one very powerful heater often worse?
Note: follow safety clearances, select the correct IP rating, and comply with local electrical rules.
Depending on wind exposure and shelter, compare Heatstrip infrared heaters and Heatscope heaters.
