⚙️ Overview
The Hansø Electric Heater (1500 W, IPX5, remote-controlled) provides radiant warmth ideal for use beneath closed or partially open Pro+ pergola louvers.
Each heater effectively warms about 70–90 sq ft (6.5–8 m²) depending on ambient temperature and wind exposure.
The number of heaters needed depends on your pergola’s size, layout, and intended use (dining, lounge, full-coverage, or edge heating).
📏 Recommended Heater Quantities per Pergola Size
Pergola Model | Total Covered Area | Typical Use | Recommended Heaters | Suggested Layout |
Pro+ 10 × 10 ft (3 × 3 m) | ≈ 100 sq ft (9 m²) | Dining for 4 – 6 | 1 – 2 units | One centered on long beam or one on each 10′ beam |
Pro+ 10 × 13 ft (3 × 4 m) | ≈ 130 sq ft (12 m²) | Lounge / dining | 2 units | One heater per 13′ beam, angled 20° toward center |
Pro+ 13 × 13 ft (4 × 4 m) | ≈ 170 sq ft (16 m²) | Dining + seating | 2 – 3 units | Two opposite beams or two side + one center beam |
Pro+ 13 × 19 ft (Double Bay) | ≈ 250 sq ft (23 m²) | Large lounge | 3 – 4 units | Two heaters per bay, on main beams |
💡 Tip: For partly open layouts or breezy sites, add one extra heater to offset heat loss.
🧱 Mounting Recommendations
✅ Mounting Points
Attach only to main structural beams (not cross-louvers).
Use supplied Hansø heater brackets or stainless M6 hardware.
Align parallel to the louvers for uniform coverage.
🔩 Hardware
Each heater weighs ~4 kg (9 lb) — beams can support multiple units safely when evenly distributed.
Torque bolts firmly but avoid deforming the beam wall.
📐 Angle & Height
Parameter | Recommended Range |
Mount Height | 2100 – 2300 mm (7 – 7.5 ft) from floor |
Tilt Angle | 15 – 30 degrees downward toward seating |
Spacing Between Units | ≥ 600 mm (24 in) |
⚠️ Safety Clearances
Surface / Object | Minimum Clearance |
Heater → Louvers | 300 mm (12 in) |
Heater → Beam Edge | 50 mm (2 in) |
Heater → Wall / Fascia | 200 mm (8 in) |
Heater → Furniture / People | 900 mm (36 in) |
Never install heaters where they can directly contact louver panels or accessory wiring.
⚡ Electrical Planning
Pergola Size | Typical Heater Count | Total Power Draw (1500 W ea) | Circuit Recommendation |
10×10 | 1–2 | 1.5 – 3 kW | 15 A GFCI outlet |
10×13 | 2 | 3 kW | Dedicated 15 A circuit |
13×13 | 2–3 | 3 – 4.5 kW | 20 A circuit or split dual 15 A |
13×19 | 3–4 | 4.5 – 6 kW | Two dedicated 15–20 A circuits |
Each heater includes a 1.9 m (6.2 ft) cable with plug.
Use outdoor-rated GFCI outlets (IP65) within reach or have an electrician hard-wire through pergola posts.
Avoid running heater cables with motor or lighting circuits to prevent overload.
🧰 Installation Sequence
Complete pergola assembly and verify it’s level.
Plan heater positions relative to seating zones.
Mark and pre-drill holes on beam underside.
Attach brackets, leaving room for wiring path.
Mount heaters and tighten securely.
Connect to outlet, test with remote, and check heat coverage.
💡 Tip: Always test heaters with louvers partially open to confirm upward heat disperses safely.
🧼 Maintenance & Inspection
Interval | Task |
Every 3 months | Wipe reflector and housing with dry cloth |
Every 6 months | Check bracket bolts and wire condition |
Annually | Inspect plug, reseal cable grommets, test remote |
5000 hours | Replace heating element (as specified) |
🚫 Do Not
Mount heaters to louver frames or slat walls.
Overlap heating zones too closely (may cause discoloration).
Use non-IPX5 heaters outdoors.
