Are you already dreading the biting cold and chilly temperatures that come with winter? Maybe it’s time to start preparing way in advance so you can ensure that your bedroom is a comfortable space even on chilly evenings. A room heater is an efficient, dependable, and inexpensive appliance that is essential for every homeowner. With room heaters, you can walk around your home freely, forgetting about the freezing cold!

However, with so many different options available today, choosing the right one for your room is a confusing decision to make. Worry no more, Crompton is here to smoothen out the decision-making process! Let’s start by understanding how the two different room heaters function:


How Does an Oil-filled Room Heater Work?

Also know as an oil-filled radiator, this type of room heater transfers heat around the room through the metal columns that emit heat. Oil is heated up at the base of the heater by a heating element which then flows around the cavities of the heater by convection. 

Despite being filled with oil, it is electrically warmed and doesn’t consume any oil fuel. The oil is utilised as a hotness supply, not as fuel.


How Does an Infrared Room Heater Work?

Although infrared heating is a new concept in the market, it has technically been around for ages. Have you ever sat on a beach and enjoyed a good sunbath? That’s a good example of infrared heating.

An infrared heater transforms electricity into warmth. Consequently, our skin, clothes, and other objects in the room soak up this heat, resulting in warmth. 


Difference between Infrared and Oil-filled heaters 

There are mainly two types of room heaters: oil heater and infrared heater. 

The main difference between the two is that an infrared heater is designed to provide quick heating whereas an oil heater focuses on heating your room evenly with more strength. In addition, there are stark differences between the two. Let’s take a look at some of them:

Heating Speed 

An infrared room heater works at the speed of light! It only needs a full minute to start spreading warmth. This heater is best if you’re freezing and need to warm up as fast as possible. In contrast, an oil filled heater is slow. Due to the oil fuel, it takes several minutes for the heater to begin heating. 

Crompton’s oil filled heater is designed with a quick heating fan with a 400w PTC heating element, enabling quick heating.

Heating Efficiency 

Infrared heaters heat objects specifically. They are fast and efficient at heating up, making you feel warm in their presence instantly. On the other hand, oil heaters spread warmth evenly. Thanks to the big oil container inside, they manage to stay warm longer.


As our bodies are designed to tolerate infrared rays, an infrared heater is natural and safe and you can leave it on overnight, too. 

Oil heaters may be a bit trickier. Crompton’s heater comes up with an automatic safety switch that switches off the heater in case of overheating or if the heater falls down.


Infrared heaters are lightweight and easy to carry, making it more portable. Oil heaters are slightly heavier due to the oil canister. 

Crompton’s oil heater comes with wheels at the bottom. So if you ever need to shift the heating to another room, all you have to do is roll it there!


Infrared heaters are best for heating smaller areas. They won’t work as well as heating big enclosed rooms. On the contrary, oil heaters aren’t as versatile in terms of outdoor heating.


Infrared heaters are as comfortable as sitting for a sunbath. They provide dry heating, something our bodies are already used to.

Crompton’s oil filled room heater comes with 3 pre-defined heat settings that can be adjusted to suit any size room and temperature needs. Additionally, the oil is heated first, spreading heat without depleting the oxygen. 


An infrared room heater consists of a power conversion stage and a heating stage. It doesn’t require maintenance and is easy to fix in case it breaks.

An oil filled heater has a similar conversion and heating stage. But the heating element is located in the metal body and can be more complex to fix.


Although both types of heaters are available in the lower price category, infrared heaters are a little bit more economical than oil heaters.
