Types of Room Heaters

Convection Room Heaters

The convection room heaters consist of coils/wires/ceramic elements as there heating element. These heating elements get heated up with the electricity which in turn heats up the air around them through convection.

 Now some of the heaters come equipped with a fan that assists airflow through the coil hence increasing the efficiency of the room heater however, some of the models don’t have fans in them and so you may notice lower heating efficiency as compared to the room heaters equipped with the fan.

These heaters are a good choice for warming up the whole room. However, you may feel some time delay in heating up the whole room. But your room remains warmer for a longer time even after switching off your convection room heater.

Oxygen Depletion

As per the research, the warmer air tends to reduce its oxygen-carrying capacity and so every room heater will reduce the oxygen level in your room to some extent. However, the real health problem is due to the breaking of oxygen molecules and converting into carbon monoxide. The heaters with open to air heating elements tend to produce more carbon monoxide due to the burning of minute dust particles and oxygen inside your room at a high temperature of the heating filament.

But if you can keep your room ventilated then this heater can work fine and are affordable too.


  • Better coverage area compared to radiant room heaters.
  • Better to warm a small room instantly compared to radiant heaters
  • Affordable
  • Price range Rs.1000 to Rs.3000


  • Overheating is a big concern
  • Higher energy wastage due to lesser heat at the bottom
  • Little noisy due to fan
  • Not advisable to be used in closed room while you asleep

Below is the list of top convection room heaters /Fan Heaters

Radiant Room Heaters

The radiant room heater produces infrared technology to heat your room. These heaters produce infrared radiations by using halogen, quartz or ceramic. Therefore, it is also named halogen room heaters, quartz room heaters, ceramic room heaters, and tungsten room heaters respectively in the market.

In this technology, electricity passes through a quartz tube or a halogen lamp which result in heat generation in the form of infrared radiation. These radiation travels until stopped by a solid object which then absorbs these infrared radiations to get heated. These are more suited for spot heating which means you will feel the heat instantly if seating in front of the heater and heat dissipates as soon as you switch off your room heater.

Oxygen Depletion

Yes, oxygen depletion also takes place in this technology and so even you will find the company saying to use it in a ventilated room.  The heating tube present in room heater reaches the high temperature which enables oxygen depletion in your room.

Apart to this, it is also said to maintain safe distance from the radiant room heaters since sitting close may result in skin problem due to excess exposure to Infrared radiations.

 So in order to keep safety in mind you need to keep your rooms well ventilated during night and keep a safe distance from the heater.

Oil Filled Heaters

This technology room heaters are considered to be the best and safest of all other available room heating technologies in the market. Also these heaters provide heat for longer duration of time too as compared to any other technologies. These room heaters are also known as column heaters, oil-filled heaters, oil-filled radiators, column radiators.

As the name suggests, most of the readers think that these heaters may burn oil which may cause pollution and may have high maintenance costs, but that’s not the case with these heaters.

These heaters have oil inside the airtight sealed fins. The heater is used to heat the oil to very high temperatures inside the heater. The heater element and oil do not come in direct contact with air which makes it safe even for un-ventilated rooms. Now the heated oil in the fins, in-turn transfers the heat to the surrounding air.

A large number of fins will result in the heat dissipation area and so the higher efficiency for heating your room quickly.

Oxygen Depletion

As on paper this technology does not enable any oxygen depletion and is certified to be used indoor without any feeling of suffocation. However, with the rising heat, there is a reduction in air oxygen carrying capacity but chance of generating carbon monoxide is almost nil or reduced to very low level that its can safely be used overnight.

However you may experience slow results with the rising temperature but once oil gets heated to the set temperature, it can remain heated for the longest duration even after you switch off your heater. Since oil inside the heater remain hot even after you switch off your heater.

These are the costliest room heaters with a range starting from 7000 to 12000 as compared to other counterparts which you can easily get at 1000-4000 range.


  • The oil inside the heater remains intact since it’s not being used as fuel
  • No oil fumes as the oils are in a sealed enclosure, used just to transfer heat
  • Best healthy room heating technology and best suited to heat a large room evenly.
  • Retain heat for a longer time
  • Can also be used in a closed room, Child safe
  • The price starts from Rs. 7000


  • Expensive
  • Don’t expect instant heating. Since it first heats up the oil inside which in turn heats up fins and then room air starts heating up. It may take half an hour to start noticing a temperature change in your room.
  • Heavy built, provided with wheels to move around
