How to Choose the Best Electric Oil Filled Radiator

How do you choose the best electric oil filled radiator in 2024? What properties and features should the best electric oil filled radiator have to suit your needs? Read our guide and make an informed choice.

The Best Electric Oil Filled RadiatorIn the quest to find the most efficient and effective heating solution for our homes, electric oil filled radiators have become a top contender.

Their energy-efficiency, quiet operation and ability to maintain consistent warmth are just a few of the qualities that make them a popular choice.

One of the most prominent advantages of oil filled radiators is their heat retention prowess.

The oil reservoir can sustain its temperature for an extended period, providing a consistent heat source long after the appliance has been switched off.

Furthermore, these radiators don’t disrupt the tranquillity of your home with unnecessary noise and won’t excessively dry out your air, making them a favoured option for those with sensitive skin or respiratory conditions.

Today, we’ll delve into the process of selecting the best electric oil filled radiator for your needs.

Why Choose an Electric Oil Filled Radiator

Unlike other electric heaters, oil filled radiators are more efficient due to the principle of heat dissipation. If an air heater or a convector heats only the air in the room, the oil filled radiators do more than that, contributing significantly to the warming of the walls of the room where they are located.

Although they are heavier than an aerotherm, they retain the heat for a long time after they have been shut off, offering a higher thermal inertia.

Electric oil filled heaters are also the most reliable electric heaters, most models are equipped with overheating and auto-stop protection functions in case of overheating of the radiator.

Another advantage of oil filled radiators to other heating appliances is silence. Combined with high heating power and high efficiency, the electric radiator is the cheapest way to heat your home using electricity.

Best Electric Oil Filled Radiators: How to Choose

When choosing the right electric oil filled radiator according to your needs, you have to keep in mind some of the criteria and features that you will find in your chosen product. Below are the main features and criteria that can help you choose the best electric oil radiator for your needs.

Heating Power

The heating power of your electric oil filled radiator is crucial to its effectiveness, and this parameter should never be overlooked. It’s usually measured in watts (W) and dictates how much heat your radiator can produce.

Powerful and efficient electric oil filled radiatorThe rule of thumb for gauging the heating power you require is to allow approximately 100W for each square metre of space. To put this into perspective, a room measuring 20 square metres would need around a 2000W radiator for effective heating. However, this is a general guideline and other factors could influence your requirement for heating power.

The size and insulation quality of the room can significantly impact how much heat is retained. For instance, rooms with high ceilings or large windows may lose heat quickly and may require a radiator with more heating power. The same applies to rooms with poor insulation or those with drafty doors or windows.

Moreover, the external climate is another determinant. If you’re living in a region with harsh winters, you may need a radiator with higher heating power to maintain a comfortable temperature indoors. All these factors play a pivotal role in deciding the right heating capacity for your needs.

Energy Efficiency and Thermostats in Electric Oil Filled Radiators

Energy efficiency is a paramount factor to consider when choosing an electric oil filled radiator. An energy-efficient model might cost you a bit more upfront, but it could save you significant amounts on your energy bills in the long run.

One of the key features that enhance the energy efficiency of a radiator is the thermostat. The thermostat controls the temperature of the radiator and ensures that it operates within your chosen parameters. If the room temperature drops below the set level, the thermostat will activate the heater to bring the temperature back up. Conversely, when the room temperature exceeds the set level, the thermostat will turn the heater off.

There are two primary types of thermostats – mechanical and digital. Mechanical thermostats are the traditional type and are usually more affordable. However, they are less precise and could lead to slight fluctuations in room temperature.

On the other hand, digital thermostats provide more accurate temperature control. They can maintain the room temperature within a narrow range, leading to less energy wastage. Some digital thermostats even allow you to programme temperature schedules for different times of the day, helping you save energy when the room is unoccupied or during the night when less heat may be needed.

Additionally, many modern electric oil filled radiators come with ‘Eco’ modes or similar energy-saving features. These modes optimise the radiator’s operation to save energy while still ensuring a comfortable room temperature. They work by alternating between periods of high and low heat output or by minimising the power draw of the unit.

Safety Features of an Electric Oil Filled Radiator

As beneficial and essential as heating appliances are, they come with inherent risks, making safety features a paramount factor to consider when choosing your electric oil filled radiator.

Timer and thermostat electric oil filled radiatorOverheat Protection

Perhaps one of the most important safety features, overheat protection automatically shuts off the heater if it starts to overheat. This feature prevents the unit from becoming dangerously hot, mitigating the risk of damage to the heater itself and reducing the potential fire hazard. When the temperature of the unit drops to a safe level, the heater can be switched back on manually.

Tip-Over Switch

This feature is especially important for homes with children or pets. The tip-over switch instantly turns off the heater if it is knocked over, helping to prevent accidental fires. Some models might also have a switch that turns off the heater when it’s moved, which can be particularly useful if you plan to frequently transport the heater between rooms.

Thermal Cut-Off

Similar to overheat protection, a thermal cut-off feature will turn off the unit if it reaches an unsafe temperature. This might be due to an internal fault or if the heater is covered by an object like a blanket or piece of clothing. The heater can be reset once the obstruction is removed and the unit has cooled down.

Cool-Touch Exterior

While electric oil filled radiators are generally safer to touch than other types of heaters, some models come with a cool-touch exterior. This feature ensures that the surface of the heater stays cool, preventing burns if you, your children, or pets accidentally touch the heater.

Child Safety Lock

Some advanced models may come with a child safety lock feature. This locks the control panel, preventing children from accidentally changing the settings or switching the heater on or off. This feature is particularly beneficial if you have curious little ones around.

Cord Storage

While it might not seem like a safety feature, cord storage can reduce the risk of tripping over the cord or of it being pulled, potentially tipping the heater over. It also helps keep the area around the heater tidy, reducing the risk of flammable material coming into contact with the heater.

While these safety features significantly mitigate the risks associated with using a heater, it’s important to remember that they do not replace the need for careful operation. Always ensure the heater is placed on a stable, level surface, away from flammable materials. Never cover the heater or use it to dry clothes, and always turn it off if the room is unoccupied or when you’re sleeping.

Safety should never be an afterthought when choosing a heating solution. The right safety features can provide peace of mind, ensuring that you can enjoy your electric oil filled radiator’s warmth without having to worry about potential hazards.

Additional Features of an Electric Oil Filled Radiator

Aside from the fundamental aspects like heating power, energy efficiency, safety features, and size, there are several additional features that can enhance the functionality, convenience, and overall user experience of your electric oil filled radiator.

Noise Levels

Electric oil filled radiators are generally very quiet, but the noise levels can vary between different models. Some may produce a faint humming or ticking sound during operation, which could be irritating if you’re sensitive to noise, especially during sleep. Therefore, it can be worthwhile to look for models that are specifically designed for quiet operation.

Remote Control

Some modern electric oil filled radiators come with remote controls for added convenience. With a remote, you can adjust the settings from anywhere in the room, allowing you to control the heat without getting up from your comfortable spot. Some advanced models might even allow you to control the heater via a smartphone app.

Programmable Timer

A programmable timer is another convenience feature that can be a game-changer. This allows you to set the heater to turn on or off at specific times. For instance, you could program it to start heating your room before you wake up in the morning or to turn off once you’re snug in bed. Not only does this feature enhance convenience, but it can also help save energy.

Design and Aesthetics

While the primary function of an electric oil filled radiator is to provide warmth, it’s worth considering its aesthetic appeal since it’s likely to be a visible part of your room.

High quality oil filled radiatorSome models come in sleek, modern designs or various colours that can blend seamlessly with your room décor or even serve as a stylish accent piece.

Indicator Lights

Indicator lights can be particularly helpful, providing a visual confirmation of the heater’s status. Some models might have separate lights to indicate when the heater is turned on, when it’s heating up, and when the set temperature is reached.

Anti-Frost Function

Some heaters come with an anti-frost function, where the heater turns on automatically if the room temperature drops below a certain level. This can be particularly useful in preventing pipes from freezing during cold winter months.

Cable Management

Some radiators include a place to store the power cord when not in use. This can be handy when moving the heater between rooms or during the summer months when the heater is in storage.

In summary, while these additional features might not be strictly necessary for the functioning of the electric oil filled radiator, they can significantly enhance its convenience and usability.

Therefore, it’s worth considering them when choosing a heater, and they could tip the balance when choosing between two similar models.

Size and Mobility of the Electric Oil Filled Radiator

Size and mobility are two significant aspects that need careful consideration when selecting your electric oil filled radiator.


The size of the radiator plays a vital role in both its efficiency and its fit within your space. An undersized radiator may struggle to adequately heat a large room, leading to it running continuously and consuming more energy. Conversely, a radiator that’s too large for a small space may heat the room too quickly, causing discomfort and energy wastage due to frequent on-off cycles.

When considering the size, it’s also essential to take into account the physical space that the radiator will occupy. Ensure you have a suitable place in your room where the radiator can be situated without causing inconvenience or posing a safety hazard. A smaller model might be more suitable for a bedroom or a small living room, while a larger model might be a better fit for an open-plan living area or a large office space.

Remember, the size of the radiator directly affects its heat output. Larger radiators have a larger surface area, enabling them to emit more heat and warm up larger spaces more efficiently.


The ability to move your radiator from one room to another adds a significant level of convenience and flexibility. If you need heating in multiple rooms at different times, it’s much more cost-effective to have a portable radiator than to buy separate heaters for each room.

Most electric oil filled radiators come with caster wheels and a handle, making them relatively easy to move around.

Electric oil filled radiator with wheels and handle for easy mobilitySome models even have cord storage features to keep the power cord out of the way when moving the unit. However, remember that larger models, while they may have wheels, can still be quite heavy and could be more challenging to move.

In addition, if you’re planning to frequently move the radiator, consider a model with a robust build quality to withstand the wear and tear of regular movement.

One other point to consider related to mobility is the length of the power cord. If it’s too short, you’ll be limited in where you can place the heater, or you may need to use an extension cord, which can be inconvenient and create a potential tripping hazard.

In conclusion, the size and mobility of an electric oil filled radiator are pivotal factors to consider depending on your specific heating needs and the available space. A radiator that’s appropriately sized and easily movable can significantly enhance your comfort and the overall heating efficiency.

Brand Reputation and Warranty

Finally, the reputation of the brand and the warranty offered on the product are factors worthy of attention. Established brands are often synonymous with superior build quality and performance. Furthermore, a substantial warranty period provides the reassurance that your investment is secure, and any defects or malfunctions within the stipulated period will be addressed by the manufacturer.

It’s also essential to read customer reviews and ratings about the product and the brand’s after-sales service. It will give you an idea about the real-life performance and reliability of the product and the customer service experience of the brand.

Ready to Choose

After considering all these aspects, you should be well-equipped to choose an electric oil filled radiator that best suits your needs.

Keep in mind, though, that the “best” radiator isn’t necessarily the one with the highest capacity or the most features, but the one that effectively caters to your specific requirements and fits within your budget.


Choosing the right electric oil filled radiator may initially appear to be a complex task. However, equipped with the right information and a clear understanding of your needs, you can navigate the process with ease. A well-chosen radiator can provide you with the comfortable, efficient, and safe heating solution you seek.

By understanding the basics of how these radiators work and what features to look for, considering factors such as heating capacity, size, portability, energy efficiency, safety features, brand reputation, and warranty, and weighing in additional features that can enhance your experience, you can make a well-informed decision that ensures you stay warm and cozy during those cold months.

Remember, investing time in research and consideration now will pay off in the long run, ensuring that you choose a model that offers the best combination of performance, efficiency, and value for money. Happy heating!
