Winters are already upon us and we need to prepare ourselves for the season. What is the best solution to stay warm and cozy between freezing temperatures? Yes, room heaters.
The most convenient way to combat the freezing cold and add warmth to any space is to use a room heater. Do not let falling temperatures haunt your daily life.
There are tonnes of room heaters available in the market from various leading brands, offering ample choice to every type of buyer. But to get the most out of your hard earned money you need some considerations to buy the right heater. Explore the different types of room heaters first.
Types of Room Heaters
When it comes to heating methods, there are primarily 3 types of room heaters available in India. Almost every room heater works on either of these heating principles. Here they are:
1. Convection or Fan heaters:
A convection heater is a type of heater that uses convection currents to heat and circulate air. These currents circulate throughout the body of the appliance and across its heating element. This process, following the principle of thermal conduction, heats up the air, reducing its density relative to colder air and causing it to rise.
As heated air molecules rise, they displace cooler air molecules down towards the heating appliance. The displaced cool air is heated as a result, decreases in density, rises, and repeats the cycle.
Hot air circulates around the room with the help of a fan. Instant heating, ideal for a small room but not very efficient due to high power consumption.
Top Convection Room Heaters in the Market:
- Ideal for a small/medium sized room.
- Safety cut-off.
- Thermal cut-off.
- Two heat settings-1000 W/ 2000 W.
The product causes a little noise due to the fan inside it. Use a normal socket of 15-16 Amp. It’s good for a single person.
Size is tiny, you can carry in a travel bag.
- Ideal for a small/medium sized room.
- Two heat settings – 1000W/2000W.

2. Radiant or Infrared Heaters:
Uses infrared rays to heat the nearby area and generate warmth. Ideal for small heating space, inexpensive, energy-efficient but not child safe.
An infrared heater or heat lamp is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Depending on the temperature of the emitting body, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm. No contact or medium between the two bodies is needed for the energy transfer.
These are for small heating purposes and are also inexpensive as compared to other types. Better pick for a person with allergy because of no or low-powered fans.Image below shows a radiant heater.

3. Oil filled heaters
An oil heater, also known as an oil-filled heater, oil-filled radiator, or column heater, is a common form of convection heater used in domestic heating. Although filled with oil, it is electrically heated and does not involve burning any oil fuel; the oil is used as a heat reservoir (buffer), not as a fuel.
The oil acts as a heat reservoir to warm the surrounding air. Useful for rooms of all sizes, energy-efficient, but is an expensive choice.
Oil filled heaters are most popular in the market today owing to their effectiveness, efficiency, and safety. Inside the body is diathermic oil which serves as a heat reservoir. Electric energy channeled in is converted into heat. The heat is absorbed by the diathermic oil and is circulated through the fins and columns.
Top Oil-filled room heaters in the Market:
- 9 fins oil filled radiator.

|Large Space Heating||Ideal For Heating a large room||More Suited for a Small Area||More suited for small area.|
Costly than other two types(Rs.10000 approx)
|usage||Retain Moisture in the air||Retain Moisture in the air||Can Dry Out the Air|
Best Room Heater Suitable For Large Room:
Considering all three types of room heater, radiant heaters are not suitable for large room. They produce infrared radiations to heat the space around without heating the air. Convection heaters generate heat instantly which is pushed out with a fan. They are very economical in price but high on energy consumption with around 2000 watts. Oil filled heaters are best suited for large room. They are most expensive of all three types but can help you save on electricity bills.
Best Room Heater Suitable for a Small Room:
When buying a room heater for a small room. Radiant heaters come to the mind because of low power consumption. They are also very inexpensive costing around Rs.1000.
Fan or convection heaters are also suited for a small space as they provide instant heat and at the same time are very economical. Only factor against fan heaters is their operating cost which can be high. But they are also safer in comparison to radiant heaters.
In case budget is not a concern, you can also consider buying oil filled heaters which are high on safety as well as operating costs. However, Oil-filled room heaters can cost anything around Rs.10000.
Key Features to Consider Before Buying Room Heater:
Timers: Allow you to set heater turn on and turn off times. This helps you save energy and also is very convenient.
Wattage: Wattage of a heater defines the area it can heat. High wattage indicates large area heating capacity,
Portability: Providing mobility wheels or handles make transporting your room heater a breeze. Portable room heaters are appropriate for use at different places very easily.
Automatic oscillation: It helps to evenly distribute the heat in room. This feature is most common in fan heaters where oscillation spreads hot air across the room.
Multiple heat setting: It gives you more control to heat different sized spaces. Multiple heating settings also add to the functionality as the heater can be used in variable temperatures conditions.
Safety Settings: Overheat protection switch is a must-have feature to keep the internal components at a safe temperature. Heater automatically shuts off after reaching a predetermined temperature.
Light Levels: A heaters may emit bright light which can cause discomfort during night hours. Look out for the level of light emitted by the unit.
Safety Mesh: Most heaters come with a safety mesh in the front. Check whether the slats are close enough for safe usage with children and pets in the room.
Type of Plug: Check whether the heater uses a standard or power plug. For safe operation, additional wiring may be required with a power plug.
