Once winter hits, a good room heater becomes the most-used appliance at home. In the oil-filled radiator (OFR) category, two models are very commonly suggested — Bajaj Vienna 13-Fin oil-filled heater and Havells Hestio 13-Fin Wave-Fin OFR (2900W). On paper they look very similar, but in real use they suit two different types of buyers. Here is a simple human-style comparison.
Bajaj Vienna — What kind of heater is it really?
Bajaj Vienna is for people who want slow but comfortable heating that feels like natural room warmth instead of a blower. Since it is an oil filled room heater with no fan, it heats gradually — but once the room is warm, it maintains the temperature quietly without drying the air.
It’s the kind of heater you turn on and leave running for hours — perfect for bedrooms, kids rooms, elderly rooms, and overnight heating. It comes with a thermostat, castor wheels and built-in safety features like thermal cut-off.
In short: Steady, silent and safe — ideal for long use and night-time heating without noise.
Havells Hestio — What makes it different?
Havells Hestio 13-Fin is positioned as a premium oil filled heater. The main difference is that it includes a PTC fan heater for faster heating, so instead of waiting long for warmth, the fan helps raise temperature quickly and then the OFR maintains it. This makes it ideal for living rooms and offices where people want quick comfort.
It also offers premium touches such as wave-fin design, inclined controls and retractable wheels, which make it easier to move and store.
In short: Faster heat + premium design + extra convenience — but comes at a higher price and slight fan sound when PTC is used.
