Radiant room heaters or infrared room heaters are the best for those who are on a budget because they are the cheapest. They normally work like the campfire which means that you need to be near the heater to enjoy their warmth. As a result, they are the best for small spaces or individuals.

One of the major benefits of these units is that they provide instant heat since they provide heat directly. They are also energy efficient and silent. Some of them feature wooden cabinets which makes them look like the wooden furniture.

You will also find that most of them are equipped with a ribbon filament or a quartz tube which helps to transfer heat directly to you once you have switched the unit on. Radiant heaters are quiet and don’t affect the humidity levels in the room.

Oil filled radiators are one of the best heaters to purchase.  The good thing about them is that they neither burn oxygen nor reduce humidity in the room. They consume less electricity and are super quiet. All these features make oil heaters the safest room heaters among all options.

They feature a series of joined columns which are attached to a base that contains a control panel. Inside the columns, there is diathermic oil which functions as a heat reservoir. Note that the oil doesn’t act as a fuel which means that you don’t need to refill. Since they use an internal fluid to heat a large exterior metal surface, these units do not require a fan to circulate hot air which means that they provide hot air through convection process.

However, they take some time to heat up and they are also bulky. Some oil filled heaters also come with a small inbuilt fan.

  • Energy efficient
  • Quiet performance
  • Safest room heater
  • Smart features such as the auto off , thermostat, etc.


  • Expensive
  • Takes some time to provide warmth

Oil Heater vs Fan Heater vs Radiant Heater – Which one is better?

If you live in a studio apartment or you live alone, a radiant or a fan heater will be the best because they are suitable for small rooms. They are also cheaper and more compact than the oil filled heaters.

Between fan heater and radiant heater, a fan heater may be suitable if you want quick, widespread heating and don’t mind the noise and potential air dryness. On the other hand, if you prefer quiet operation, energy efficiency, and targeted warmth, a radiant heater may be a better option.
