Ajay is a postgraduate in thermal engineering from the Indian Institute of Technology (IIT) Ropar. His research area is thermofluid dynamics and heat transfer in heated fluid droplets.
They also keep the room warm for longer, which is especially useful in areas with frequent power cuts. Furthermore, they consume less electricity and keep the room warm for longer, so let’s try to choose these types of heaters over the other, less efficient types!
Oil filled heaters use oil heat reservoirs or buffer to heat the surroundings. Generally, silicone oil is used because of its high heat capacity (~2kJ/K) and high melting point (~200°-300° C). The high heat capacity of oil enables it to store more thermal energy in smaller volumes and helps it stay warmer for a longer time.
Due to the higher melting point, the oil stays in liquid form at elevated temperatures and thus eliminating any chances of the heater becoming a high-pressure vessel.

Oil filled heaters come in a number of sizes and can have different features, which makes it difficult to select the right one. Here are a few important points you must consider to choose the best oil filled radiator for your needs.
As a reference, if you have a room of 250 square foot, multiply that by 10, so you need 2500 watts for this room. Similarly, you can remember this formula and apply it according to your room's measurements.
Oil filled heaters in India generally have 500 – 2500 Watts of power consumption. A 1000 W heater would take twice as long to heat the same space to a particular temperature than a 2000 W heater.
More wattage means it will lesser time to heat the space, but it will also increase the size of the heater. In order to increase the rate of convection, which is the mode of heat transfer in such heaters, the number of fins is increased, and thus, the size increases as well.
Those living in warmer parts of the country would not need a huge oil heater with multiple heat settings, so it would be alright if they opted for less expensive models. However, all those living in the northern and north-eastern states would have to invest a little more because winters are more severe in these regions. An adjustable thermostat or more wattage would be handy.
A thermostat regulates the temperature of the device and takes necessary actions in order to keep the temperature at the desired value. It helps prevent inefficient heating and thus reduces the power input, which in turn reduces the cost of usage.
Furthermore, for portability, look for wheels. There might be times when you would want to sit in another room and buying two heaters could be a wastage but if you look for the heater with wheels, you can easily move it from one place to another.
An oil filled heater primarily uses convection as a mode of heat transfer between oil and the air surrounding the heater's fins. Radiation and conduction also contribute to heat transfer but not to the same extent as convection.
Thinner fins increase the contact surface area, which increases the heat transfer rate and also enhances the mobility and portability of the heater.
Different weather conditions demand different heaters, so check your type and situation and then buy the desired one. Click on the link below to know more about other types of heaters and their buying guide.
Once you start using these types of heaters, you will realize how cozy and comfortable your homes can feel even during wintertime. We hope this article has helped you understand how you should choose the perfect heater and that you were able to find a suitable one for your home.
