Havells Hestio 9 Straight Fins OFR

Engineering-wise, the Havells Hestio utilizes 'U-Tech' straight fins which are optimized for convection. The inclusion of a PTC (Positive Temperature Coefficient) ceramic element is a masterstroke for the Indian market; it provides a 'quick start' function that traditional oil heaters lack. The thermal fuse acts as a secondary safety layer beyond the thermostat, which is critical in Tier-2/3 cities where power fluctuations can occur. The 1.5m cord length is sufficient for most Indian bedroom layouts where power sockets are often placed at a distance from the bed. The metal body is coated with a heat-resistant material that, while warm, avoids the severe burn risks associated with exposed halogen or quartz coils.
