Oil Filled Radiator

Best Oil Filled Radiator

Quite a while ago we wrote an article on the best wall mounted oil filled radiators, which has proved popular! However, what about those that don’t want an oil radiator to attach to their wall, and simply want to bring it into their property for the winter months? We’ve got you covered with this article which covers the best overall oil-filled radiators!

An oil-filled radiator aims to provide effective thermal conductivity while being safe and easy to use. Oil-filled radiators have been around for over a century, with the first examples appearing during the middle of the 1800s. They have been very popular in Europe and America, and many homes still use oil-filled radiators as a primary source of heat. Oil-filled radiators were made to solve the problems with hot air heaters because they can store more heat than the usual traditional heater, which is based on hot air.

Types of oil-filled space heaters

There are several kinds of oil-filled radiators to choose from. They are:

1. Standard oil heaters

These are the taller oil radiator heaters, which stand around 25 inches tall and weigh about 20 pounds. They use up to 1,500 Watts of power and can distribute heat for up to 300 square feet if used as a supplement to your home heating system or boiler.

The standard size heaters that people use at home are the conventional sort. They provide enough warmth for a normal-sized room. The majority of standard size oil-filled heaters include casters (wheels) and a carrying handle to make them easy to transfer from one space to another.

2. Mini oil heaters

Oil-filled radiator heaters are tiny versions of oil-filled radiators that measure about 14-16 inches tall and weigh around 8 pounds.

This type of heater consumes up to 700 Watts of power and may cover about 70 square feet if utilised as the main source of heat, or around 140 square feet if used as a supplement. This is the most effective heater for personal use.

The most common ways to employ them are as under-desk heaters at work, in a tiny bedroom to remove the chill from the air at night, and next to you in a living room during the day.

Because small oil-filled radiator heaters are so light and portable, they do not have wheels.

How oil-filled radiators work

Oil-filled radiators are electrical devices, but they are very different from electric baseboard heaters. Their main parts are the oil-filled radiator cabinet, a heating element, and an electricity source. The following are steps to follow when using  an oil-filled radiator:


The first step is to make sure that the oil-filled radiator cabinet has enough oil inside. You have to check an oil-filled radiator periodically, so there is no need to worry about it being empty all of a sudden. Many people use water boilers instead because they are safer, but this might not be a good idea for some who don’t want to constantly monitor the water level.

Also, oil-filled radiator cabinets are made from fire retardant materials so any excess heat will not injure you or your loved ones.


The next step is to plug in the electric cord and switch on the power source. Some oil-filled radiators do not have switches, but instead, you need to plug them in the power source and switch it on for them to work.


Turn on the oil flow from the valve at the bottom of the radiator cabinet, or whichever way your particular oil-filled radiator works. If it has a switch, flip it. If there is no switch, the oil inside the radiator will automatically flow once you plug in the power source.

Things that you need to take note of

Some people assume that oil-filled radiators are much hotter than electric baseboard heaters when using water boilers since childhood. However, you have to remember that oil-filled radiators are only used for providing heat in the form of radiation. Electric baseboard heaters are usually hot enough to cause burns, so they should be kept away from children and pets.

You also need to ensure that there is no kink or break on the electric cord when using an oil-filled radiator. Oil is very flammable, and an electric short circuit or a broken cord can cause a fire.

Oil-filled radiators are not good for outdoor use since there is a risk of water entering the device through condensation, damaging it. In addition, the device itself is expensive, so you might not be able to replace it.

Oil-filled radiators are the best alternative if you do not like hot air heaters. They are safe, easy to use, and can hold more heat than regular hot air heaters. This device should be a staple in every home, especially during cold seasons when everyone’s main concern is keeping warm.

Factors to consider before buying oil-filled radiators

There are many oil-filled radiator companies in the market today, but not all of them will provide you with good quality products. You should consider some essential factors before buying an oil-filled radiator to ensure that you’ll end up with a device that works as it is supposed to. Some of the things to look for are:

1. Coverage area

You should know the area of the room where you want to place your oil-filled radiator so you will know how big it needs to be. An oil-filled radiator with a higher wattage is generally bigger, so if you need a small size, then look for one that has less wattage.

2. Design

Oil-filled radiators come in different shapes and designs. You need to choose the most suitable one for the particular room you plan to place it in. For example, some people like tall oil-filled radiator cabinets, while others prefer cabinets with no legs.

3. Extras

Some oil-filled radiators may come with unique features that will make them more functional. You might want to check if the oil-filled radiator has a timer or if it can automatically shut down when there is no longer enough oil inside the device.

4. Wattage

 The wattage of an oil-filled radiator determines how much heat it can hold, so you should choose one that has the wattage that is appropriate for the area you want to place it in.

5. Price

Price should be considered when buying an oil-filled radiator. It is important to buy a high-quality oil-filled radiator, but it doesn’t always mean that you need to spend a lot of money on it. You should check the seller and compare the different prices offered by various manufacturers or retailers.

6. Temperature range

The temperature range indicates the maximum and minimum level of heat that an oil-filled radiator can hold. If you live in a place where the temperature is constantly changing, choose one with a wide temperature range to adjust well to specific conditions.

7. Type of oil used

Different manufacturers use different kinds of oil when making their oil-filled radiators. You should check the type of oil used in the device and determine if it’s safe for your family members. Oil-filled radiator companies use mineral oil, plant oil, or refined oil in their products.

8. Ease of use

If you’re buying an oil-filled radiator for your elderly family members, choose one that is easy to use. Some oil-filled radiators are complicated and might need special maintenance or extra care.

9. Size

The device’s size should be appropriate for the area in which it will be placed. It shouldn’t take up much space, but it should also be able to hold enough oil so it will be able to produce sufficient heat.

10. Number of cords

Some oil-filled radiator cabinets have one cord, while others have more than one cord. If you want your device to generate more heat, choose one with many cords. However, don’t forget to check the cord length as well.

11. Cord management

Many oil-filled radiator cabinets come with built-in cords, but some do not have this feature. If you want your device to look more organised, choose one with internal cords because it will be easier to manage them.

Differences between a baseboard heater and an oil-filled radiator

Electric baseboard heaters are often mistaken to be oil-filled radiators. Although they both give out heat, they are not similar. Here are some of the differences between a baseboard heater and an oil-filled radiator:

1. Design

An electric baseboard heater comprises an electric heating element enclosed in a long panel with a thin cover on it to hold the oil inside. Meanwhile, an oil-filled radiator has a cabinet filled with oil, which is then converted into heat. An electric baseboard heater can be placed anywhere you want it, but an oil-filled radiator should only be placed in areas where it won’t be knocked down easily because of its weight.

2. Coverage area

An electric baseboard heater is best for small heating areas, particularly those that are up to 12 feet away wheres; an oil-filled radiator can heat larger areas because the type of oil used in it can retain heat for a long time.

3. Wattage

An electric baseboard heater has lower wattage than an oil-filled radiator, but the wattage of the two devices are similar when they are both turned on at their maximum settings.

4. Design of controls

An electric baseboard heater comes with a dial that you can twist to control the temperature, while an oil-filled radiator has knobs that you turn to adjust it. 

Benefits of using an oil-filled heater

Having an oil-filled heater is beneficial for several reasons. Here are some of them:

1. Environmentally-friendly

Oil-filled heaters are eco-friendly because they do not emit pollutants, which can harm the environment. They only release water vapour and carbon dioxide when in use. There are no harmful elements that can damage trees or plants while this heater is in operation, unlike other types of heaters such as electric ones.

2. Noise-free operation

Oil-filled heaters do not produce much noise when in use because they do not have any moving parts inside them, unlike other types of heaters such as electric ones that come with fans.

3. Low maintenance requirements 

An oil-filled radiator is a low-maintenance device that needs little or no regular cleaning. You only have to wipe the outside panel with a clean, dry towel or cloth for the dust to stop accumulating on it.

4. Lasting heating power

Since oil-filled heaters store heat longer than other types of heaters, such as electric ones, you can turn it off when you leave your home and when you come back, the room will still be warm.

5. No risk of burns

Unlike other heaters with heating coils, oil-filled heaters do not have any exposed parts that can cause you to suffer burns if you accidentally touch them while they are in operation.
