How Oil Room Heaters Work

Oil room heaters are also called Oil Filled Radiators (OFR) or oil heaters.

  • These heaters consist of hollow columns/pipes of metal, which are connected to each other – these are called fins. A special type of oil is filled in these which is called diathermic oil.
  • Due to the heating element placed under the heater, this oil also gets heated. This hot oil flows through all the fins due to which heat is spread in the air/atmosphere of the room.
  • Nowadays, these heaters come with a small fan which pulls the (cold) air of the room from one side and puts it on these hot fins. Thus the air present in the room gets heated quickly.
  • This diathermic oil, filled in the fins, remains hot for a long time, which has the advantage that even if we turn off the heater, it continues to heat the room for a long time.

That is, oil in the heater is not used as a fuel, but as a heat reservoir (buffer).

Advantages of Using Oil Room Heaters

It has many advantages:

  1. Energy Efficient: Since the diathermic oil used in these maintains the heat for a long time, these heaters are energy efficient. Keeps the room warm comfortably for 1-2 hours if you switch it off or there is a power cut.
  2. Even Heat Distribution: You must have noticed that some heaters are not able to spread heat to other parts of the room. But as these heaters transfer heat through convection and thermal radiation, the room gets heated evenly.
  3. Oxygen not burnt: Most of the infrared and fan heaters burn the oxygen present in the room due to which the level of oxygen present in the atmosphere of the room decreases and can cause suffocation. However, the oil room heater works on the principle of convection and thermal radiation in which there is no oxygen burning in any way.
  4. Thermostat and auto thermal shut-off: These heaters often come with a thermostat that senses the temperature inside the room and maintains the temperature level you have set in your room. They also have an auto thermal shut-off feature that turns off the heater when the room gets warm enough.
  5. Minimized risk of fire or burns: The hot oil in these heaters is trapped in their fins and never comes out. Apart from this, its fins do not get so hot that touching them can burn someone. Still, it should be kept at a certain distance.
  6. There is no dryness in the skin: Since they do not eliminate the moisture present in the room, therefore dryness is not felt in the skin.
  7. Portability: Most of the oil room heaters coming today have wheels at the bottom so that you can move them from one room to another without much hassle.
  8. Longevity and Low Maintenance: These heaters are highly durable and provide a service life of 15-20 years. They require minimum maintenance. You just need to check the cleanliness and safety from time to time.

Common Misconceptions about Oil Room Heaters

Despite its many benefits, there are some misconceptions people have about oil room heaters that we would like to clarify to you:

  • Consumes a lot of oil: Oil room heaters do not consume any kind of oil. This oil is sealed and packed in this heater, it is used only for heating.
  • Takes a long time to heat up: Although they don’t provide instant heat like fan heaters, they heat up fairly quickly and maintain a steady temperature.
  • They make noise: Oil room heaters are known for their silent operation, making them perfect for bedrooms or quieter spaces.

How to Choose an Oil-Filled Room Heater

It is important that this room heater suits your budget and requirements, so while buying a good oil room heater for yourself, keep these things in mind:

9 Finsup to 150 sq feet
11 Finsup to 150 to 250 sq feet
13 Finsup to 250 sq feet

Nowadays, oil room heaters with curved fins have also come on the market. Curved Fins increase the heating area of the fins and increase the heating efficiency. Therefore, you are advised to get an oil room heater with curved fins.

By the way, to heat one square foot of space, 10 watts of heating power is required. Thus, if you have a 150-square-foot room, you should go for a 1500-watt room heater.

  • Over Heat Protection – It does not allow the heater to overheat.
  • Tilt Over Switch – If the heater tilts or falls, it switches off the heater.

While purchasing, you must check these safety features. If you have small children or pets in your house then these features are very useful.

Energy Efficiency

Cleaning and Maintenance Tips

Oil room heaters are low maintenance, but periodic cleaning is necessary. Switch off the heater and unplug it before cleaning. Wipe the exterior with a damp cloth and use a vacuum cleaner with a nozzle attachment to remove dust and debris from the fans. Check the power cord for any damage and replace it if necessary.
