Havells' Heritage: Crafting Comfort Since 1958 - The Havells Hestio 9 Fin Oil Filled Radiator Review
Havells India is a household name in electricals. The company has evolved from fans and lights to sophisticated home appliances, emphasizing safety and innovation. The Hestio series, part of their room heater lineup, draws from decades of engineering expertise. It delivers oil-filled radiators (OFRs) that mimic natural convection heating. Unlike coil heaters that blast dry air, the Hestio uses finned oil reservoirs to radiate steady warmth. This technology has been refined for Indian winters. For urban dwellers battling Delhi fog or Mumbai humidity, it is a reliable ally, ensuring toasty spaces without the fuss.
The OFR Evolution: From Coils to Convection
Oil-filled radiators rose in the 1970s as safer alternatives to open-coil heaters. They retain heat longer, providing efficient, even distribution. The Hestio advances this with a PTC (Positive Temperature Coefficient) fan for an instant boost, addressing the slow warm-up gripe. In 2025, as smart homes trend, its manual controls offer simplicity. Features like 360-degree heating adapt to any room layout, making it a staple for energy-conscious households.
Design: Sleek Black Beacon of Warmth
The Havells Hestio is a design triumph. Its black powder-coated steel body stands 25 inches tall and 14 inches wide, featuring nine straight fins for optimal heat transfer. At 12kg, it is stable yet mobile, with retractable castor wheels for effortless gliding across tiles or carpets. The inclined control panel, angled at 15 degrees, puts switches at eye level—no bending required. It houses a rotary knob for three heat settings (1000W, 1500W, 2400W) and a PTC fan toggle.
Finned Efficiency
The nine straight fins, spaced for maximum surface area, hold 2.8 liters of dielectric oil. This oil heats gradually, releasing warmth for hours after shutdown. This convection design ensures 360-degree coverage, circulating air naturally without the noise of fans. It is ideal for quiet bedrooms or reading nooks. The fins' straight profile maximizes contact, outperforming wavy designs in even distribution.
PTC Fan Innovation
The integrated PTC ceramic fan heater provides instant heat. It cuts warm-up time from 20 minutes to under 5. The fan oscillates air gently for "comfortable breathing," avoiding the stuffy drafts of traditional blowers. Controlled separately, it conserves energy, activating only when needed.
Control and Mobility
The inclined panel features illuminated indicators for settings, with a cord storage hook at the base. Retractable wheels lock for safety, and the handle atop makes carrying simple. In black, it blends seamlessly into modern decor, from minimalist apartments to rustic retreats.
Build Quality
Constructed with overheat protection and tip-over switches, it is IS-certified for Indian standards. The oil is non-toxic and sealed for life, with a 2-year warranty on heating elements. A minor note: the fan's hum is audible at high speeds, but it is softer than standalone heaters.
Performance: Radiant Heat That Lingers
The Hestio excels in delivering consistent, room-filling warmth. Its 2400W max output heats 250 sq ft in 15-20 minutes. The oil's thermal retention keeps spaces cozy for 30-45 minutes after being turned off, a boon for power-conscious users. Three settings adapt to needs—low for overnight, medium for lounging, and high with fan for rapid thaw.
Heat Distribution
360-degree convection rises naturally, warming floors to ceilings evenly. There are no hot spots or cold corners. The PTC fan accelerates this, blending forced air with radiant heat for hybrid efficiency. This feature is ideal for drafty rooms or quick guest arrivals.
Energy and Efficiency
At 2400W, it draws like two fans but uses oil's high specific heat (2.1 kJ/g°C) for sustained output. This results in a cost of approximately ₹10/hour at full blast. The fan mode at 1000W sips energy, extending runtime without compromise.
Quiet Operation
Unlike noisy coils, the OFR operates near-silently. You may only hear faint oil circulation gurgles. The PTC fan, at 40dB, rivals white noise, making it perfect for sleep or work calls. "Comfortable breathing" means humidified air, preventing dry throats.
Safety and Durability: Peace of Mind in Black
Safety is paramount with the Hestio. It features thermal cut-outs that prevent overheating beyond 95°C. A tip-over sensor automatically shuts off the heater if it is tilted. The IP20 rating guards against splashes, and the cord length (1.5m) keeps it accessible. Built for over 5 years, the sealed oil needs no refills, and the wheels endure daily rolls.
User Voices: Toasty Testimonials
Owners rave about its "even, gentle heat" for winters. They praise the fan for speedy startups and the wheels for portability. Families appreciate the safety features, while seniors like the no-bend controls.
