How to Calculate the Right OFR Fin Count
- Small Bedroom (Up to 100 sq.ft): 9 Fins (2000W) — e.g., Havells OFR 9 Fin.
- Medium Bedroom (100 – 150 sq.ft): 11 Fins (2500W with PTC fan heater) — e.g., Morphy Richards OFR 11F.
- Large Living Room (150 – 220 sq.ft): 13 Fins (2500W–2900W) with wave-fin design.
Essential Safety Checklist Before Purchase
- Tip-Over Safety Switch: Automatically cuts power if the unit is knocked over by children or pets.
- Overheat Thermal Protection: Cuts off power if temperature exceeds safe operating thresholds.
- Castor Wheels with 360° Swivel: OFR heaters weigh 11–15 kg; sturdy castor wheels are essential for rolling between rooms.
- Cord Winder & 16A Power Plug Requirement: All 2000W+ heaters require a dedicated 16 Amp power socket with proper earthing.
