Best Oil Filled Radiator Heaters in 2021 [Reviewed]

An oil-filled heater is one of the best ways to go if you’re looking for a reliable radiator as a primary or secondary source of heat. They are also a great way to economically heat a room. In fact, a well-built oil heater can produce up to 99% energy efficiency since nearly all of the electricity consumed is converted to heat.

The heat will then radiate out from the fins into the room and cause the hot air to rise, thereby creating a circulation that spreads the heat to the room. Though this process can be slow since the radiator heater does not use fans or heating coils, it uses less energy compared to an electric heater and is completely quiet.

Whether you’re looking for a suitable oil-filled heater to use at home or at work, or maybe even in your garage or basement, this article acts as a quick guide and a review of our top picks for your consideration.

Benefits of Getting an Oil Filled Heater

Most people looking to buy an additional heater for their rooms don’t often consider oil-filled heaters as a viable option and that’s a real shame since these products do have quite a few aces up their sleeves. Some of its advantages include the following:

Energy Efficiency

Oil-filled radiator heaters are more efficient at evenly distributing heat across the surface of the room since they use convection heating methods for heat distribution.

Heat Retention

These types of heaters are typically filled with diathermic oil, which works amazingly at retaining the heat generated by the resistor inside the heater and provides you with high heating capacity.

Good Features

Most oil radiator heaters come with cool features such as thermostats, timers, protection features, etc.

Quiet Operation

They’re not as noisy compared to a fan-powered model since they do not have a fan.


Most oil-filled heaters have caster wheels and are often light enough for you to be able to move it around easily from room to room to provide heat right where you need it.

Good air quality

Since it does not have a fan to push heated air out into the room, oil-filled heaters won’t dry out the ambient air in a room.


Many portable heaters tend to get hot on their surface which may burn anyone who touches it. But this isn’t the case with oil-filled heaters. Though they do get warm to the touch, it’s certainly not hot enough to cause a burn.

Factors to Consider before Buying the Best Oil Filled Radiator Heaters

Before you can arrive at your decision on which oil-filled radiator heater is the best choice for your needs, it’s prudent to familiarise yourself with some of the key features first. You should also ensure that you have a specific budget in mind and remember that the more perks a certain radiator has, the price will often be higher too. This guide will assist you in differentiating great value options from the rest by outlining the key specs of a good oil-filled heater.


When it comes to heating products, output really does matter. There’s no point in spending money to buy a product that will not supply you with a decent amount of heat. If you already know the size of the room you want to heat, then you’ll be in a better position to decide what heating capacity your radiator should be.

In general, the most powerful models consist of a heat output ranging between 1500W to 2500W. Anything over 2000W may be a slight overkill since this level means you fall into a category where value and energy efficiency aren’t so great.

On the other hand, 600W should really be the minimum wattage you ought to look out for. Though such a setting isn’t going to make a huge difference, it may just be convenient enough to help you keep warm in a small study.


Portability is yet another important characteristic that you should consider. A radiator without wheels will be pinned down in only a single room. You will have to wait for it to cool off so that you can lift it up and carry it should you decide to use it in a different room.

The wheels also act as a buffer between the floor and the body of the heater. Since these heaters are mostly used on all kinds of wooden floors, or carpets, you might want to have some buffer distance between the two for safety purposes.

Safety Features

Safety is a very important feature and you should never ignore its presence or absence in a heater. A tip-over switch ensures that an oil-filled radiator remains safe, especially when you have pets or children running around the house. Apart from preventing the product from malfunctioning, these safety functionalities also prevent a complete fire hazard disaster from occurring.


Your oil-filled radiator heater’s style will also play a role in your decision, and it doesn’t just come down to the different color options available. Certain people will focus on how the product looks and how it blends into their room decor.

The size of the heater is also an important consideration due to the liquid it holds inside. Generally, the bigger the body, the more time it will require to heat up since it holds a larger amount of oil inside. Though this may sound like an inconvenience, it doesn’t necessarily have to be so.

Once the radiator heats up, this large body will begin to emit enough warmth to heat up your room. After the fins and oil are hot, they’ll remain so for a while. Therefore, a larger body implies slower convection but also a lengthened cooling-off period.

Timer Control/ Crucial Heat Settings

The way you operate space heaters will help in determining the possibilities that the product has, the level of comfort it produces, as well as the price. Certain oil heaters come with a digital display with a few friendly beeping sounds when you press the buttons.

Most electric heaters come with a timer function. In fact, even some analog heaters have that ability as well, plus they do come at a relatively lower price. What’s more, the added digitalization could likely cause more things to go wrong. If your software or display somehow goes bad, you may end up having to pay even more money to fix it.

Generally, oil heaters only have one purpose and that’s to heat up the room. The money’s value in a product doesn’t lie in the costly, flashy product but rather in one that will surely keep you warm and comfortable on the coldest nights.

Additionally, it is also good to have a heater with a thermostat with a minimum of two power output settings. A thermostat will work to switch off the heater once a certain temperature is achieved, thereby making it more energy-saving as well. The output settings will enable you to pretty much decide on the heater’s power consumption at any given moment.
