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

Particularly for Smaller Areas
There is also an additional fan, which can be turned on to speed up the process of heating. Furthermore, the switch for the additional fan is located at the heater's back, which may be hard to reach after the heater has been in use for a while.
For Small to Medium Sized Rooms of 150 to 200 Square Foot
Although this heater is not great for rooms larger rooms with 350 sq. ft and above areas since its outer body can get pretty hot while in use. The PTC fan may become a bothersome feature for some, too, as it can be quite noisy and make it harder to fall asleep.
3 Adjustable Thermostat Setting for Faster Heating
Being equipped with 3 heat settings, you can start using 1000 wattage setting from December when the winters are warming up, and a 2300 wattage for extreme cold weather. It has overheating protection as well, so even if you leave and forget the power on, it will stop automatically.
An Affordable Noiseless Heater for Colder Regions
However, it does not have a temperature indicator nor a tip-over safety switch, and any kind of breakages or short circuit is not covered in the one year warranty. The built-in PTC fan is a great feature for faster heating, but it adds to the heater's weight, making it slightly heavier and more difficult to carry.
Noiseless and Sturdy 200 Watt Radiator for Medium Sized Rooms
You can easily take it from one room to another as it is not too heavy and comes with wheels. Furthermore, it may be a bit difficult to operate as the heater buttons do not have markings and the adjustable thermostat is merely a dial without any indicators.
Children-Friendly Heater
The biggest downside to this product is its slow heating as even in small spaces, it can take quite some time to warm up. Therefore, it is not recommended for those living in colder parts of the country or those on a budget.
For Steady Heating in Smaller Rooms
On the downside, though, this heater takes almost half an hour to warm up even a medium-sized room, and it is very noisy as it creates clicking noises after it’s been turned off. Many users have praised its air quality as it doesn’t dry up the room.
