How To Decide Between Fan, Radiant Or Oil-Filled Room Heater?

The cold season is just around the corner, and we need to be prepared for it. A few of us dread the cold season, while certain others enjoy nothing more than being in a cozy blanket with a hot cup of cocoa and your favorite book.

Either way, you will need a room heater to keep you warm from the freezing cold. Most families would have already started searching for a good quality room heater. However, it would be a bit confusing because of the wide range of choices.

This article will discuss the different types of room heaters, their pros and cons, and the features we should consider before buying a new room heater.


Different Types Of Room Heater 

1. Fan Room Heaters

Fan Room Heater

Fan room heaters are also known as ceramic heaters, convection heaters, or blower room heaters. The name “conventional room heater” comes from the conventional technology it uses to heat the room.

The appliance works by heating the metal coils or panels within, and then the heat is circulated in the room using an in-built fan.

Pros – 

  • Suitable for small and medium-sized rooms.
  • Ensure that the room is quickly heated (not applicable for large rooms).
  • Fan room heaters are very popular since they’re affordable.
  • The whole unit is lightweight; hence can be portable.
  • They are the safest when it comes to families with small children.

Cons – 

  • They can be a bit noisy due to the in-built fans.
  • It alters the oxygen and humidity level.
  • Not very energy efficient when it comes to large rooms.
  • It is not an ideal room heater during humid conditions.


2. Radiant Room Heater

Radiant Room Heater

They are also known as infrared room heaters as they work based on infrared radiation. However, they are suitable only in small spaces. If you are on a budget, then this is your pick, as this heater is the cheapest on the list.

The working of a radiant room heater is pretty simple – the heater generates rays of heat which heats the surface it falls on. This indirectly heats the whole room. So, they provide instant heat while being energy-efficient and silent.

Pros – 

  • Provides instant heating in small spaces, hence is energy efficient.
  • The design is compact.
  • It is the cheapest in the market.
  • It does not have an in-built, so it works silently.

Cons – 

  • These heaters tend to overheat.
  • Radiant heaters alter the oxygen and humidity level.
  • Not suitable for families with small children.
  • Not ideal for large spaces.


3. Oil-Filled Room Heaters

Oil-Filled Room Heater

Even though oil-filled room heaters take some time to heat the room, they are one of the best heaters in the market. This is because the heater does not burn the oxygen in the room, nor does it reduce the humidity level.

Plus, they are silent and very efficient. The oil is heated, which acts as a heat reservoir, providing the room with heat even though the heater is switched off.

Pros – 

  • Oil-filled room heaters are safe for families with children.
  • They work well in large spaces and are energy efficient.
  • Oil-filled room heaters do not alter the oxygen or humidity level.
  • Most oil-filled room heaters have smart features like auto-off, thermostat, etc.
  • It has a quiet working performance.

Cons – 

  • It takes time to heat the whole room.
  • Oil-filled room heaters are expensive.


9 Things To Consider Before Buying A Room Heater?

1. Wattage And Energy Efficiency

Wattage is the amount of power consumed by the heater. Fan heaters consume about 1500-2000 watts, while radiant heaters consume 800-1200 watts.

However, oil-filled heaters are considered the best with regard to electricity consumption and energy efficiency since they consume only 1000 watts (maximum). Since the oil acts as a heat reservoir, oil-filled room heaters consume less energy when compared to fan and radiant heaters


2. Humidity and Oxygen Level

Oxygen is essential for our survival, so it is best to avoid heaters that work by reducing the oxygen level in the atmosphere. Fan room heaters and radiant room heaters reduce both the oxygen level and the humidity in the room.

Whereas oil filler heaters heat the oil, which acts as a heat reservoir; thus, oxygen is not burnt, nor is there any reduction in the humidity level.

If the room is not very big, and you need not buy an oil filler heater, you can place a bucket of water in one corner of the room while the fan heater or the radiant heater is functioning. If this does not work, you can buy a humidifier.


3. Automatic Oscillation

Automatic oscillation means the even distribution of heat to the entire room. This is possible with a fan heater as well as an oil-filled heater. In a radiant heater, the generated heat only heats the area where it falls. So, the heat distribution might not be even.


4. Heating Time

After spending a whole day out in the freezing cold, all you want to do when you get home is sit in a warm cozy atmosphere. But the problem is not all heaters produce instant heat. Fan and radiant heaters have the ability to heat the room quickly.

An oil-filled heater takes much more time in comparison as it has to heat the oil first. Only after the oil is heated is it able to heat the room. But even though it takes more time to heat the room, the room stays warm even after the appliance is turned off.


5. Size Of The Room

Room Size

If you are searching for a room heater to heat a small space, then a radiant heater or fan heater is apt. If you are a bachelor, I would suggest that you buy an infrared heater because a fan heater can generate heat for two to three people. However, if you want to heat a bigger room, then don’t buy either of these heaters; your best bet is an oil-filled room heater.


6. Portability

If you are someone who travels a lot, especially to cold places, then this should be an important factor while you look for a room heater. Fan heaters and radiant heaters are lightweight, which means that they can be easily transported.

On the other hand, oil filler heaters are a bit bulky and are more difficult to transport.


7. Noise Level

Noise Level

Fan room heaters are extremely noisy due to the in-built fan. On the other hand, radiant heaters and oil filler room heaters are quiet compared to the fan heater due to their radiance technology.

So, in case you have elderly people in the house or even babies, then the best heater is an oil-filled room heater. Not only does it not produce much noise, but it is safer than a radiant room heater.


8. Safety

If we rate the heaters from the least safe to the safest one – first we would have the radiant heater, then the fan heater and the safest one is the oil-filled room heater. Radiant heaters overheat, and this can become dangerous.

An oil-filled room heater does not have such a problem, so it is considered the safest heater, especially in families with small children.

Other than this, it is also good to check if the heater has additional safety features like a protective grill, an automatic turn-off switch, and a cool-touch feature.


9. Price, Warranty, And After-Sale Services

Fan and radiant heaters are priced almost the same, but the oil-filled room heater is quite expensive. Whatever heater you buy, make sure that the company provides after-sale services and the appliance has a warranty period. Also, make sure to go through the review before you buy any room heater.

Weighing out both the pros and cons of each room heater, we can conclude that the most energy-efficient and safest one is an oil filled room heater. Even though it is a bit expensive and takes longer than the other two to heat up, it is worth the money. But the final choice is up to you and your preferences.
