Benefits of Having an Oil Filled Radiator Heater

Benefits of Having an Oil Filled Radiator Heater
Oil filled heaters are the perfect solution to cold, dry winters, especially if you want to use them in smaller rooms because they suck the cold air and push it through the oil filled fins. They do not make the air in the room any drier and retain more heat because they take time to heat up and cool down.

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.

How to Choose an Oil Filled Radiator Heater in India – Buying Guide

Oil filled radiator heaters are an energy-efficient way to keep your house cosy during the winters. Although they take a while to heat up, they are sure to keep the room warm and comfortable for a much longer time. The heating element in oil heaters is dipped in silicone oil to maintain the oxygen and moisture levels of a room.

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.

Consider the Wattage Before Buying

Consider the Wattage Before Buying
It is extremely important to choose a heater based on your room's size because otherwise, it will either end up being insufficient or too expensive for your need. So check the appropriate wattage before buying. It is simple! You need 10 watts of power for every square foot. 

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.

Determine Your Budget Based on the Severity of Winter in Your State

Determine Your Budget Based on the Severity of Winter in Your State
An oil-filled radiator's price varies depending on several factors such as the size, the model, and the kind of oil used in it. For safety, you can also look for additional features like an adjustable thermostat to control the heat or an auto-cutoff to save electricity or after reaching the heat limit.

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. 

Choose Durable and a Portable One

Choose Durable and a Portable One
While choosing an oil filled room heater, one of the most important things to keep in mind is its durability. Ideally, an oil heater made out of steel is sturdy, durable, and easy to maintain. 

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. 

Ajay Gairola

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.
