Buyer Guide to Choose the Best Oil Heaters

How Does It Work?

The mechanism of this product is simple and represents a valid option to increase the heating level of your home. In practice, the radiator is filled with a particular type of oil which, when the device is connected to the power outlet, is able to accumulate heat and diffuse it into the room.

The process does not involve any consumption of the oil (which heats up but does not burn) therefore it must in no way be topped up or replaced.

Another advantage, especially in comparison with traditional electric heaters, is a much lower energy consumption (even up to 75% less) as well as a very low risk of short circuit.

The reason for park consumption is linked to the fact that, once the oil has reached the desired temperature, the appliance switches off automatically.

Once the oil cools, the radiator turns on again and brings it back to temperature. Electric heaters, on the other hand, never go out and therefore impact more significantly on consumption in the bill.

Nice and Compact

It is true that a product of this type must fulfil its function and is therefore purchased mainly to heat the environment. But since it is a piece of furniture, why not opt ​​for a model that is also aesthetically pleasing?

Maybe it will not be at the top of the list of aspects to be taken into account but it should not be underestimated anyway.

Comparing the prices, you will notice that on the market it is possible to find radiators of all types and therefore also models with harmonious shapes and pleasant colours, able to integrate with your furniture or to be well represented in any environment.

Weight and transportability are also not elements to be underestimated, because the lighter the device, the easier it is to move it to operate it where it is needed.

Safety First

The radiators of the best brands are able to regulate on and off in order to limit both energy consumption and the risk of short circuits.

The most advanced radiators, in fact, are equipped with safety systems that intervene immediately in the event of an accidental fall, an abnormal overheating, or that integrate the anti-frost function. From this point of view, you can choose an oil appliance without any hesitation.

Of course, the integration of more advanced features has an impact on the sale price, which tends to rise. Scrolling through our reviews, however, you can find products that make them convincing the relationship between quality and price one of their sharpest weapons.

The cost discriminant is also determined by the size of the environment you need to heat: in a large room, a very small radiator will certainly go into difficulty and will be undersized.

Simple to Move

The advantage that these devices have, compared to a central heating system, is the possibility of selecting the room to be heated and ignoring the rooms where there is no need to raise the temperature.

Unlike halogen or more bulky gas stoves, the oil radiator is equipped with four pre-assembled wheels, which will allow you to move it comfortably in the selected room.

This is an element that should not be underestimated, especially if you are thinking of giving the device to elderly parents who would not be able to move it if there was a need to lift it.

In addition, a practical handle located on the front makes it easier to grip the radiator, thus preventing it from getting out of hand. Finally, there is also a cable reel, extremely convenient for hiding the power cord and preventing it from hanging around.

Internal Battery

The new design of the internal coil, specially design, allows increasing the radiant surface, thus obtaining maximum heat exchange and efficiency. The power of the device is 900 watts, adjustable on three different power levels to adapt to your needs.

One of the drawbacks encountered by users concerns the maximum power level. As it happens in fact for most oil radiators, when subjected to intense heat, they emit an unpleasant smell of oil and burnt plastic, in reality, it is not an alarming element and there is no risk of overheating of the product, however, part users find this smell extremely unpleasant and hardly tends to go away even with prolonged use.

Room Thermostat

An interesting element of the radiator is the possibility of regulating the thermostat so that, as soon as the desired temperature is reached, it switches off, turning on again only when there are variations downwards.

This is a very important element for energy saving, since it reduces ignition times, allowing you to consume less electricity.

How to Use the Oil Heaters

When the cold is upon us, it’s time to gear up for the best and avoid beating a bad thing or breaking a few teeth by banging them.

The solutions are different and among these, we must mention the oil radiator, an effective system thanks to which the climate of a room can be made milder, otherwise, it would remain freezing.

How Does Oil Radiator Work?

The operation of the radiator is nothing complicated. Inside there is a particular oil that heats up due to the heat given off by a resistance. Do not mislead the presence of the oil: this substance does not run out and does not require a change.

The radiator does not require an excessive commitment in terms of energy consumption since, once the desired temperature is reached, the resistance switches off. The hot oil will take care of continuing its work of maintaining the temperature on pleasant levels.

Of course, the time will come when the oil will cool down but do not panic, the resistance will activate again to bring the room temperature up again.

No Installation

You may be led to think that such a radiator should be installed but this is not the case at all. The only thing you need to do is insert the cable into the electrical socket.

It is a great advantage because, in this way, it can be transported to any corner of the house. There is no installation but practically no maintenance. It is ideal for those who love simple things and who do not require attention.


Oil coolers are absolutely safe devices. There is no danger that they will explode or start a fire. Their surface also remains cold, therefore, if it were accidentally touched, burns would not occur.

No substance is left in the air and the fearsome carbon monoxide is not produced, which can happen, for example, with the stove.

Stove or Radiator

One thing we must say, radiators are not able to heat as much as a gas stove, moreover like electric stoves and other appliances of this kind. However, the advantage remains of not emitting harmful substances into the air and optimizable consumption.

Keep in mind that a gas stove must always be turned off manually, it is not able, for example, to understand what temperature to reach, stop, and then turn back on if necessary.

What Not to Do?

How many times have we seen mom take advantage of the radiators turned on to warm the still-wet clothes? Well, if this practice is not recommended for radiators, it is even more so for hate radiators.

The reason is as follows: heat is prevented from spreading into the environment and therefore energy is wasted.

Frequently Asked Questions

What Is an Oil Heaters?

An oil radiator is an appliance for domestic heating similar to normal wall radiators, with the difference that in the elements inside, instead of water, a special oil circulates that is not consumed and which increases the yield of the system, both in terms of heating power and in terms of electricity consumption and duration of heat.

Like traditional radiators, moreover, also the oil models are available in different versions, for wall mounting or portable, so that they can be easily moved if necessary or transported if necessary.

Why Choose an Oil Heaters?

The range of users who live in rented outdated buildings, with obsolete or completely out of service systems and without further alternatives in this regard, is the one that makes the most use of stoves and heaters and therefore is very careful with the subsequent management of the costs of the device.

Oil radiators are among the favourites in this market segment, precisely because they have greater efficiency. The oil that circulates inside the elements.

In fact, has special thermal properties, heats up faster, and maintains the temperature of the water longer, which allows it to consume less electricity than a convector or a traditional radiator.

How Much Does an Oil Radiator Consume?

The “consumption” of the oil radiator refers exclusively to the electricity that is needed to heat the oil; the latter in fact, as we mentioned earlier, circulates in a closed system.

It should not be replaced nor is it subject to wear out in any way, unless the radiator suffers material damage that compromises the structural integrity of the heating elements.

The energy consumption, therefore, is the nominal one of the chosen device and can vary from 500 to 2,500 Watts depending on the type. In addition, some models also integrate the fan, thus managing to further increase their efficiency.

How Does an Oil Radiator Work?

The oil radiator is similar to the traditional radiator also as regards the operating principle. In fact, in the heating elements, instead of water, an oil circulates that has special thermal properties.

Then, on the bottom of the heating elements, immersed in the oil but not in direct contact with it, there is an electric heater powered by a circuit equipped with a thermostat.

Once in operation, the resistance remains on until the oil reaches the temperature set on the panel, at which point the thermostat switches it off and on again only when the room temperature starts to drop again.

Is the Oil Cooler Dangerous?

In terms of danger, heating appliances with heating elements in contact with air are to be feared more than radiators. The radiant elements are based on a closed system, similar to that of radiators, which makes them extremely safe.

Furthermore, the oil inside them is never in direct contact with the resistance, and the latter is always equipped with additional shielding to isolate it completely from the other elements that make up the radiator.
