Oil Filled Radiator Buying Guide

Oil-filled radiators are generally portable electric heaters that are usually oil-filled and are heated by a single or more electric elements. Additionally, the oil is permanently sealed and doesn’t need refilling. Oil-filled radiators offer a mixture of convection and radiant heat, unlike other types of electric heating.

That implies that they heat the air in the room and directly heat the items within it. As a result, it allows the room to have a comfortable warmth without having to dry out the air. In this guide, you’ll learn more regarding the features you should look out for when buying an oil-filled radiator, how it works, some of its benefits, and the costs involved.

In this guide, you’ll learn more regarding the features you should look out for when buying an oil-filled radiator, how it works, some of its benefits, and the costs involved.

Key Takeaways

  • Oil-filled radiators are portable electric heaters that offer a combination of convection and radiant heat, making them effective at warming the air and objects in a room.
  • When buying an oil-filled radiator, consider its power output, wheel portability, safety features like tip-over switches, design and size, price, timer control, and heat settings to make an informed decision.
  • Oil-filled radiators are cost-effective and efficient heaters, with the ability to maintain warmth even after turning off, but their running costs depend on factors like power output and electricity rates.

Key Features to Consider

Before you can arrive at your decision of getting an oil-filled radiator, it’s prudent to familiarise yourself with some of the key features of one. Ensure that you have a specific budget in mind and remember that the more perks a certain radiator has, the higher the price will be. There’re a few great value options, and this guide will assist you in spotting them by outlining the key specs of a good oil-filled heater.

Oil Filled Radiator


Well, output matters. You don’t require 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 how strong you think your radiator should be.

Generally, the most powerful ones consist of a heat output between 1500W and 2500W. Anything over 2000W may be slight overkill. However, you fall into a category where value and energy efficiency aren’t so great at such a level. After all, maybe you should look for something that will do a great job but won’t significantly increase your energy bills.

At a minimum, 600W is the wattage you should look out for. Though such a setting isn’t going to make a huge difference, it may be pretty convenient for a small study.


Portability is another important characteristic that should be present. A radiator without wheels will be pinned down in only a single room. If you want to move it, you’ll have to wait for it to cool off so that you can lift it and then carry it to wherever you want. Such an ordeal is certainly not pleasant to anyone.

What’s more, the wheels act as a buffer between the floor and the body of the heater. People keep those heaters on wooden floors or carpets, and you want to have the proper distance between the two. That also shows you that a set of wheels will play a significant role in safety.

Safety Features

Safety is an essential feature, and you should never ignore its presence or absence. If an oil-filled radiator includes a tip-over switch, then there is a high likelihood it will be safe. This feature is of utmost importance to you for those with pets or children running around. Apart from preventing the malfunctioning of the product, it will also avoid a complete fire hazard disaster.


Your oil-filled radiator heater’s style also plays a role; it doesn’t come down to just the colour options. Certain people focus on how a product looks and usually find themselves passing on a good deal due to the thing that doesn’t “compliment” their specific living room setting.

What’s more, the size of a heater is also very important due to the liquid inside. Generally, the bigger the body, the more time it will require to heat up. Though it sounds like an inconvenience, it doesn’t have to be. Once the radiator heats up and this large body begins to emit warmth, you could turn it off.

It will, therefore, take more time for that radiator to cool off. After the fins and the oil are hot, they’ll remain in that situation for a while. Therefore, a larger body implies slower convection but also lengthened cooling-off period. Though it comes down to your specific preference, this trade-off is worth it in many cases.


Besides oil-filled radiators being very reasonably priced, they feature among the most affordable heating devices available, starting from as low as £25. Since these radiators are cost-effective, you’ll have to look for a model with the specific characteristics to suit your requirements. Setting out your own needs will assist you in making the right choice.

Timer Control/ Crucial Heat Settings

It’s a crucial aspect of every oil-filled radiator heater since the way you operate it will help in determining the possibilities that that product has, the level of comfort, as well as the price. Certain heaters come with a digital display, and they additionally make a few friendly beeping sounds when you press their buttons.

Though it sounds like fun, is it really that essential? Regardless if you rotate dials or press buttons to operate your heaters, it shouldn’t be all that necessary. Most electric radiators also come with a timer function. In reality, however, some analogue ones also comprise that ability and tend to come at a relatively lower price.

What’s more, the more digitisation you include, the more things are likely to go wrong. And after your software or display goes bad, you will incur a cost to fix. Generally, a heater has a single purpose and is certainly not associated with being perky. The money’s value doesn’t lie in the costly flashy product but rather in the one that will surely improve your room’s temperature.

Additionally, you certainly require a heater that has a thermostat and a minimum of two power output settings. Usually, the thermostat will switch off the thing once a specific temperature is achieved. The output settings will enable you to decide on the heater’s power consumption at any given moment.

Oil-Filled Radiators

Frequently Asked Questions

How Does an Oil-filled Radiator Work?

  1. Electricity flows into the resistor of the heater, which then turns the energy into heat
  2. Absorption of heat through the inert diathermic oil within the heater
  3. Once the oil starts to heat up, it flows via the radiator fins and columns, in the same way as a stream of hot water flowing via plumbing
  4. Heat transfer between the heater’s metal fin and the warm oil occurs, allowing an even level of warmth
  5. While the metal fins start to heat up, they produce heat into the room. It moves throughout the space via natural air convection

What are the Advantages of an Oil-filled Radiator?

  • Oil-filled radiators contain no fans; this makes them near silent
  • No fan implies that the oil heater won’t need to dry the air in your room
  • Electric heaters practically 100% energy efficient. Due to the absence of a fan motor in this oil-filled heater, it makes it ultra-efficient
  • Oil-filled heaters have a longer-lasting warmth, even after cutting off the power
  • Once space or room reaches the required temperature, the device will then cycle on and off to keep that warmth and even save as much energy as possible, instead of just running non-stop
  • Since the oil is not a fuel source, it won’t be necessary to replace it

How Much Does It Cost to Run an Oil Filled Radiator?

When it’s first switched on, the device will run at full power, attempting to heat the oil to operating temperature. If the radiator can’t heat the room to the required temperature, it will continue to operate at full power. It’s the worst-case scenario for calculating running costs.

You could look at the maximum power output of the oil-filled radiator and your latest bill’s cost per unit of electricity to determine its maximum running cost. Remember, an oil-filled radiator’s power output is measured in Watts.
