LINEA 14 D
Modular double vertical tube radiator · fully customizable widths · heights 400–2400 mm · maximum thermal capacity
General Information
The Geber LINEA 14 D is a premium modular radiator featuring double vertical parallel round tubes (diameter 14 mm) arranged in pairs for enhanced thermal capacity. Minimalist linear design with fully customizable width. Welded onto round collectors Ø35 mm with epoxy powder coating finish.
Fully Modular System: Width is calculated as (n° of elements − 1) × 40 + 25 mm, where each element = 1 pair of tubes adding 40 mm spacing. Double tube configuration delivers superior thermal output. Available in all standard RAL colors and custom finishes. Perfect for contemporary interiors demanding flexible, design-driven heating solutions.

📊 Thermal Performance Per Double Tube (ΔT=50°C)
| Height (mm) | Inter-axis (mm) | Thermal Power per Pair (Watt at ΔT=50) | Example: 5 Pairs (185 mm width) |
|---|---|---|---|
| 400 | 350 | 18 | 90 W |
| 600 | 550 | 27 | 135 W |
| 800 | 750 | 36 | 180 W |
| 1000 | 950 | 45 | 225 W |
| 1200 | 1150 | 54 | 270 W |
| 1400 | 1350 | 63 | 315 W |
| 1600 | 1550 | 72 | 360 W |
| 1800 | 1750 | 81 | 405 W |
| 2000 | 1950 | 90 | 450 W |
| 2200 | 2150 | 99 | 495 W |
| 2400 | 2350 | 108 | 540 W |
Modular Width Configuration Formula
Width (mm) = (n° of elements − 1) × 40 + 25
Examples (Double Tube Pairs):
- 3 pairs: (3−1) × 40 + 25 = 105 mm width · 54 W at 400 mm
- 5 pairs: (5−1) × 40 + 25 = 185 mm width · 90 W at 400 mm
- 10 pairs: (10−1) × 40 + 25 = 385 mm width · 180 W at 400 mm
- 15 pairs: (15−1) × 40 + 25 = 585 mm width · 270 W at 400 mm
- 20 pairs: (20−1) × 40 + 25 = 785 mm width · 360 W at 400 mm
Each element = 1 pair of vertical tubes with 40 mm spacing. First pair = 25 mm offset from left edge. Fully customizable to any width requirement. Superior thermal output compared to single tube configuration.
Technical Notes
- Thermal Output Per Pair: Values shown are for a double Ø14 mm vertical pair at ΔT=50°C (water at 75°C, ambient at 20°C). Total output = number of pairs × output per pair.
- Double Tube Advantage: Superior thermal capacity compared to LINEA 14 S. Each pair delivers approximately 50% more heat than single tubes for maximum comfort and efficiency.
- Fully Modular Design: Width is infinitely adjustable using the formula. Order any number of pairs to achieve desired width while maintaining fixed height.
- Vertical Configuration: All tube pairs run vertically from top to bottom collector Ø35 mm. Clean, contemporary minimalist aesthetic suitable for modern interiors.
- Pressure/Temperature: Max operating pressure: 8 bar · Test pressure: 12 bar · Max temperature: 95 °C
- Finishes: Epoxy powder coating. Standard colors: White RAL 9010 and all RAL/NCS options. Custom finishes available upon request.
- Availability: Heights from 400 mm to 2400 mm. Widths customizable from 3 pairs (105 mm) to any maximum width required.
