So, what is an oil filled heater exactly and how does its system work?
An oil filled heater resembles the old type of radiator but is smaller in size. It is made up of metal columns with open spaces between the columns. The heating element at the base of the heater will then heat up the oil before it flows around the metal columns of the heater through the process called convection.
After the metal columns are heated, they spread the heat to the room through the conduction heating method. This is when you will feel that the surrounding air has increased in temperature.

How to Choose the Best Oil Filled Heater
When we say “the best choice,” it’s actually kind of subjective and depends on a person’s preference. But as a rule of thumb, there are 7 key features that you must consider when buying an oil filled heater.
Here are the 7 things to look for in an oil filled heater:
1. Power Output
The power output of the heater is one important consideration. Power input refers to how much energy is consumed per time period while power output is the power that the heater releases to actually warm up the room.
In other heater types, the power input and output have a slight difference with the output slightly lower than the input. However, the good thing about oil filled heaters is that they usually have the same power consumption and output, which ranges from 300 to 2400 watts.
If you have a big bedroom, it’s better to buy a heater with a higher power output to ensure that all corners of the room are well heated.
2. Power Levels
Because of the advent of technology, heaters nowadays may come in various power levels. A heater with multiple power levels allows you full control over how warm you want your room to be. Usually, an oil filled heaters can have 500W, 1000W, and 1500W power levels.
With this function, you can turn the heater full force for the first few hours, and then reduce it to the minimum level just to maintain the heat.
The Thermostat is a crucial part of every heater. Why? Well, this is because thermostat is the one responsible for detecting the current temperature of the room so that it can perform the best action.
This device controls and maintains the heat circulation by regulating the flow of the heat transfer within the metal columns of the oil filled heater.
As we said and as what many users revealed, an oil filled heater is safe to use overnight. This is why a timer is a very useful feature to look for. You can even set time intervals so that the heater will automatically turn off the heat as you go to work and turn back on when you arrive from work in the evening.
5. Tilt Protection
To guarantee that the heater last longer, tilt protection is a must. The tilt protection works by automatically turning off the heater when it is knocked over. With this auto shut down that comes with the tilt protection, damage can be prevented.
6. Remote Control
Of course, remote control is quite helpful to adjust the temperature of the heater. During night time when you need to increase the heat level, the wireless remote control allows you to change the temperature without you having to leave your bed.
7. Small Caster Wheels
Didn’t we mention that most oil filled heaters are actually movable? Like they have these small caster wheels that make it easier for you to move the heater from room to room.
Unlike the other types of heating system, you don’t have to worry about pricey installation process with this one. They are portable, compact, and space-saving.
