How to use it
- Calculate volume: 20m² × 2.5m = 50m³
- Factor orientación norte: 50 W/m³ (more power per lesser sol)
- Calculate power: 50m³ × 50 W/m³ = 2500 W
- Elementos of aluminio: 2500W ÷ 180W/elemento = 13.89 → 14 elementos
Common mistakes
- ⚠️ Not Consider orientación (norte requires 15-20% more power)
- ⚠️ Not prever válvulas termostáticas to control individual
- ⚠️ Ubicar radiator in lugar incorrecto (debe ir low ventana)
Worked example
Calculate aluminum radiators needed for a 20m2 room with 2.5m height.
Habitación of {area_m2}m² with orientación {orientacion} requires radiator of {power_w} W ({elementos_ud} elementos of aluminio). volume: {volumen_m3} m³.
