Best Oil Filled Heater Buying Guide

Now we have taken a detailed look at some of the best oil filled heaters. Next, we should move on to the important factors that need to be considered. These factors will directly or indirectly impact your experience as a user.

  • Noise production

All appliances, such as an oil filled heater produce some level of noise. This sound can be highly irritating and disturbing if it’s high. Moreover, if you plan to keep the heater in a room, then it’s even more annoying.

Therefore, we recommend you to check the noise output of the heater. This will allow you to choose the heater according to where you plan on using it.

There is a wide variety of oil filed heaters that come with low-sound operation technology. They might be usually higher priced, but there are some cheaper options as well.

  • Durability

When you are investing in any product, it’s important to ensure that it will last you a long time. Before buying an oil filled heater, make sure that it has high durability.

You can ensure this by checking it built material. The sturdier the material used, the better the built will be.

COSTWAY Oil Filled Radiator Heater Mini Portable Electric Room Thermostat 700W

Moreover, the heater should have certain properties that ensure durability. These can be resistance to corrosion, waterproofness, and resistance to rust and stains.

  • Portability and size

The ease with which you can move the heater around is directly related to its size and weight. If you plan to use the heater in more than one area, then make sure you buy a portable one.

Portability not only ensures that it’s easy to carry but also makes storing and placing the heater easier. Do not get fooled into thinking that compact and small-sized heaters don’t work well. If they have the right features, they will perform just as good as the bigger ones.

In fact, portability and a compact size will add more positivity and comfort in your user experience.

  • Timer functionality

We highly recommend looking for the timer functionality. If you want to invest in a reliable and comfortable oil heater, this feature is important. Even though timer will not have a direct impact on its performance, it is still important for a more convenient and positive experience.

A timer functionality will allow you to set the timer and have the heater shut off/on automatically. You will not have to put in much effort and will find the heater more dependable.

Timer functionality can also help you save costs. You will not have the heater running all night as it will shut down automatically on your desired time.

  • Safety features

Heaters, just like any other home appliance, have many hazards. They should not be left for a long time without any check and supervision. They also pose a greater hazard because of their heating element.

Therefore, it is important to ensure that the heater you choose has safety features. These are not extra features but the essentials that can be very beneficial. Such features may include rounded edges and overheating protection.

COSTWAY Oil Filled Radiator Heater Mini

Rounded edges refer to the sides of the appliance that can be sharp and threatening to children and pets. These edges can even be dangerous for adults in the house or anyone working with it. Therefore, round edges eliminate this risk of injury.

Other features like auto-shutoff protect the heater from getting extensively hot. The feature automatically shuts off the appliance once too hot. This also takes the burden off of your shoulders. You no longer will have to keep checking it for overheating.

  • Design

The design of a heater does not only refer to its appearance. Every heater has a different design and hence performs differently.

There are heaters with vertical metal columns, and some have thermal tunnels instead of fins. These design features can have a direct impact on how the heat is distributed by the appliance.

A vertical heating metal column gives out heat from the top, which also means that their bodies are cooler to touch. You can also consider this feature when looking for how safe the heater is.

Meanwhile, heaters with thermal tunnels distribute heat through “tunnels.” This process of passing through heat from thermal tunnels can mean longer time required to heat the room. However, this design is the most advanced technology and has a better heating performance.

  • Warranty

Every brand and manufacturer offer a different warranty policy with their product. So whatever brand you choose, make sure to check with their warranty first.

Warranty can be very useful if it is a generous one. It can save you the repairing and replacement costs. However, not all manufacturers come with good and generous warranties.

So, make sure to check the warranty beforehand. It will not only save you costs but will also make maintenance of the heater easier.

  • Budget and price

Of course, this is one of the most essential aspects to consider. Remember that an expensive heater does not necessarily determine good performance.

So, if you do not have a huge budget, don’t hesitate to go for a cheaper heater. You will find various competitive units in the market that work exceptionally at lower prices.

PELONIS HO-0201 3-Level Radiator Heater

Don’t pay too much for unnecessary and ineffective features. Choose wisely and spend wisely, even if you do have a good budget.

  • Ease of operation and heat settings

All heaters need you to adjust their settings according to your preferences, so they can perform accordingly. These settings may refer to timer settings, temperature control, and so on.

Before purchasing a heater, make sure that you fully understand its settings and operations. Nowadays, there are advanced heaters with easy and quick touch control panels. These panels also come with LED screens for increased clarity.

Therefore, the heater you buy should have easy, efficient, and durable setting options. It should not be too complicated for you to operate. This will have a direct impact on your experience.

The preferred variety of settings includes 2 output settings and an adjustable thermostat.

Reasons To Buy An Oil Filled Heater

You must be wondering; why choose an oil filled heater when there are clearly other options too? Well, investing in an oil filled heater will always remain the best option. This particularly applies if you have a medium sized area to cover and looking for an outperforming heating alternative.

We have come up with some remarkable reasons that will make you buy an oil filled heater:

  • Energy efficient

Oil filled heaters are widely known for their outstanding ability to transform almost 100% of their power consumed into heat. This makes them highly energy efficient. In other words, there is no waste of energy.

Tangkula Oil Radiator

Moreover, the appliance also needs to consume lesser energy to heat the same oil that was heated before. The oil stays warmer for a longer period of time.

  • Low maintenance

You do not need to worry about any cleaning, replacing, and refilling. It uses the same oil as the fuel and works just as fine.

  • Peace of mind

You will find a full range of oil heaters that come with efficient safety features. Over-tipping and overheating features ensure that you can trust and rely on them.

Furthermore, there is also the timer functionality. This allows you to rely and depend on the unit itself fully. It requires minimum effort from you.

It is also safer to have oil heaters at home with pets and children. They have fins and columns that are hardly ever heated.

NewAir Electric Oil-Filled Space Heater

The best part about oil filled heaters is that they are portable. This eliminates the need for central air conditioning. Central heaters are expensive to install and high maintenance.

Moreover, you also will not need to install heaters in every room as you can easily move the heater from one room to another.

  • Long lasting heat

Compared to water heaters and electric heater, oil heaters produce a longer lasting heat. This is because the fuel, oil, remains heated for a longer time.

Hence, you can turn off the heater and still keep the room heated for a long while.

  • No vents

Another great feature of oil filled heaters is that they do not have vents. This means that you no longer have to worry about cleaning them. There will be no issue of debris and dust building up.

Oil filters are given proper enclosure. Therefore, their airflow and performance will also not have an impact by any dust or dirt.

  • Low sound production

Oil filled heaters do not use any fans or heavy-duty machines that will produce noise. If you want to have a heater in your room but want silence, this is the best choice.

Oil filled heaters are best known for their quiet operations.

Comparison With Other Heating Options

There are other heating options in the market as well. It’s better to carry out a thorough comparison between the most common alternative of oil filled heaters. This way you will be able to choose better for yourself.

Oil Filled Heater vs. Air Conditioners

DeLonghi TRD40615E

Air conditioners are compressor-based units. They use chemicals reactions to change the temperature of the air that flows in and out through them.

Air conditioners are more appropriate for cooling the air in summers. However, they are also a huge investment to make. They are also known for putting a strain on your utility bills.

Air conditioners come in various forms, but the most common ones today are the split ACs. With air conditioners, there is no option of portability or mobility. They are also much larger in size.

So, if you have limited space, then air conditioners might not be for you. Air conditioners with advanced technology do have timer functionality like the oil heaters.

However, with timer functionality and restarting, air conditioners use a larger amount of electricity.

Furthermore, air conditioners also produce a short-lived air temperature. With oil heaters, the heat in the room stays even after the unit is off. It’s not the same case with air conditioners.

Moreover, air conditioners work by throwing cooler air out in the environment. This makes it a bad option for more open areas. You are also restricted to open windows and doors while the AC is on.

Oil heaters are also known for their efficient, equal distribution of heat. This is not the case with air conditioners. they usually focus the air in one area. This can be annoying and prove to be highly ineffective.

Air conditioners are also noisy, compared to oil filled heaters.

In addition to this, air conditioners also need to be installed in one particular place like an empty wall in a room. This means that they can’t be taken around from room to room.

This further increases inconvenience as you will need to install another AC in another room.

Oil Heater vs. Electric Heater

 COSTWAY Oil Filled Radiator Heater Mini Portable Electric Room Thermostat 700W (14

Electric heaters work by passing an electric current through the heating coils of the unit. The current then produces heat which is emitted into the environment. Some have built-in fans to distribute heat as well.

Electric hearers are solely run on electricity. This is one of the most important reasons why they are not energy efficient.

While oil heaters use a fluid like oil for heating, electric heaters only use voltage.  There is no heating liquid in electric units.

Since electric heaters have fans in them, they can be noisy in comparison to oil heaters. Electric heaters are also not a good choice due to their high safety risks.

The electric units have a much-heated body which can cause a lot of damage if touched accidentally. So if you have pets and children at home, this is not a good option for you. Due to use of high voltage, electric heaters are also not safe if they come in contact with water or wet surface.

Both oil and electric heaters are environment-friendly and pose no serious threat. So if you are environmentally conscious, you can choose either of these. However, electric units do consume lots of energy.

While oil heaters leave behind no wasted energy, it’s not the same case with electric units. There is a lot of electricity that goes to waste without producing any heat.

Their need for a continuous electric supply will definitely increase your bills. This also takes away your peace of mind that oil heaters can give.

In terms of portability, oil and electric heaters compete with each other. Oil heaters can be moved around room to room. But they do weigh more than electric heaters. This is because oil haters have a dense liquid like oil in them, while electric units do not.

Do You Need To Refill Oil Filled Heaters?

Oil filled heaters have oil filled in them as the heating liquid. It is the liquid that passes through the thermal unit for heating. However, the unit uses the same oil over and over. Hence, you do not need to refill oil again and again.

In oil heaters that work on electricity, the heating element run by electricity heats the oil. The oil never combusts or burns; therefore, the level of oil in the unit never decreases.

This is one of the greatest benefits of installing an oil filled heater. It requires the bare minimum maintenance and hence makes it convenient to use.

 COSTWAY Oil Filled Radiator Heater Mini Portable Electric Room Thermostat 700W

However, this does not mean that you never have to check or update your heater. There can always be chances of fluid leakage. In such cases, the appliance switch off the appliance and fix it instantly.

Safety tips

Any kind of heater has some kind of safety hazards with it. While oil heaters are relatively safer, you still need to take some safety precautions. Here are some ways you can ensure safe operations:

  • Plug it directly

You should avoid plugging the heater into a switch through extension wires. It’s always a much safer option to plug it in directly. Or you can also use an extension cord that is very heavy-duty. Do not use a long, light weighted small gauged extension cord.

  • Check for the unit’s safety certification

Safety certifications ensure that the unit has been tested and approved by authorities and specialists. This is essentially important.

  • Avoid fixing it yourself

In case of any damage or dysfunction, do not try to fix it yourself. For heating appliances, we recommend professional assistance. Trying to fix it yourself can lead to environmental hazards and can also damage your appliance.

  • Never leave it plugged in when not in use

PELONIS HO-0201 3-Level Radiator Heater with Quiet Operation

We highly recommend taking the plug out when the appliance is not in use. This is particularly necessary if there are children at home. Never leave the room with the oil heater on for a long time.

  • Tripping hazard

If your oil heater has long cord or wire, then there is a huge tripping hazard. This is because the cord can come in the way of children, pets, and even adults at times. We recommend buying a unit with smaller cords.

If that is not possible, then place the heater in a less-traffic area. Don’t place it in the middle of the room where there’s a lot of people. Instead, place it in the corner where a lot of people do not go by.

  • Check for safety features

As mentioned earlier, safety features are necessary. Make sure that the oil filled heater you purchase has all the necessary safety features.

Moreover, you also need to ensure that you know how these features work.


Finally, the choice of the heater you buy will largely depend on your usage and budget. However, from this detailed review of some of the best oil filled heaters, we have a clear winner. The NewAir heater seems like the perfect, an all-in-one package.

It has all the essential and extra features. It also has a nice and stylish design. Therefore, it is the definite winner of this comparison.
