If you liked the sound of our #3 best oil heater, but want something with a bit more control, then you’ll love this model.
This oil space heater is made by the same manufacturer, Pelonsi, but gives you a more precise thermostat to dial in an exact degree, upgraded metal fins that stay hotter for longer periods of time, and a wider temperature range: 40-95°F.
This electric oil heater also has an upgraded 24-hour timer that lets you turn the unit on or off after a set period of time.
The timer is great for heating up a room at a certain time of day, like right before you get home from work, or turning the heater off when it’s not needed, like in the middle of the day.
Another advantage it has over our last oil filled radiator review is an anti-scalding cover, which makes it a better choice for homes with children and pets.
If you’re looking for an oil filled heater that has Wi-Fi controls, this is one of the best (and only) options.
The include smartphone app gives you total control over the temperature and heat settings as well as the ability to set up weekly heating schedules to fit your lifestyle.

Another perk this heater has over the competition is that it can heat an area up to 200 square feet as a primary heat source. That’s 50 more square feet of coverage than any other best oil filled space heater on this list.
As a supplemental heat source, you can expect around 350 square feet of heating comfort.
This oil space heater also comes equipped with overheat protection for your safety.
This portable radiator heater is very similar to the #3 Pelonis listed above, but it has a different control panel design and its own EnergySmart technology.
The EnergySmart feature is basically the same as the Pelonis Eco Mode, where it regulates power consumption for efficient operation; however, this model has an LED light strip at the top that shows you how much energy the unit is using at any given time (standby, low, or high)
The Pelonis heater shifts between high and low heat settings behind the scenes in its Eco Mode and you only know that it’s in standby when the temperature number flashes on and off.
For this heater, you’ll know exactly what setting it’s on because of the LED light on the top.
Safety features on this heater include overheat and tip-over protection.
As for room size coverage, it heats a 150 square feet room when used as a primary heat source and 300 square feet when used as a supplemental heating source.
This is the last standard size oil filled heater recommended on this list for rooms between 150 to 300 square feet.
It comes with a classic design with manual features, making it the best budget oil filled space heater available.
There’s a turn dial for the level of heat and switches for high, medium, and low settings.
It’s not digital or push button controlled like the previous oil heater reviews on this page, but it still works extremely well.
And, if you want a standard white-colored heater that’s easy to roll around, this is a top choice for an oil space heater.
Safety features include tip-over and overheat protection.
This is one of the best mini oil heaters we recommend.
If you need something smaller or less expensive than the previous models, this Costway heater may be just what you’re looking for.

You can control the temperature with a dial but not the speed of heat output. It only pumps out heat at one constant rate.
Safety features include tip-over and overheat protection.
This is another top mini oil filled heater that stands at 16 inches tall and weighs about 6 lbs.
It’s a great oil heater for personal use at home or in the office because it fits nicely under a desk or table.
The thin design also makes it ideal for other locations around the home where space is tight.
It only uses 400 Watts and covers around 40 square feet as a primary heat source or 80 square feet as supplemental heat.
Like our #8 oil filled radiator review, this model is basic to use. It’s equipped with an on/off switch, temperature dial, and delivers heat at one constant speed. It also has tip-over and overheat protection.
This is one of the least expensive, but most effective, heaters you can buy for personal warmth.
Our final recommendation for an oil filled space heater gives you the best of both worlds.
Not only does it come in a mini size, but it produces up to 1,200 Watts of heating power. That gives between 120 to 240 square feet of coverage.

The timer comes with 96 settings, allowing you to warm any room for any amount of time, day or night.
If you need something a bit more powerful, but not as tall or heavy as some of the other heaters on this list, this is the one to buy.
Oil Filled Heater Buying Guide
What is an Oil Filled Space Heater?
An oil filled space heater is a type of heater that uses a form of convection heating to warm up a room. Although it’s filled with oil, this heater uses electricity to power the heating process. It doesn’t involve burning any oil as fuel but rather uses the oil to generate heat.
Oil heaters go by many names, including oil filled heater, oil filled radiator, oil filled space heater, and column heater.
How Do Oil Filled Space Heaters Work
Oil filled heaters are designed with long metal columns that are constructed as thin fins with cavities between them.
And inside the body of these heaters is diathermic oil.
The diathermic oil flows freely around the inside of the heater, but it’s not used as a fuel source.
Instead, the oil is warmed up through electricity by a resistor located at the base of the unit which then transfers the heats to the metal columns.
There are no fans on oil filled heaters, so as they warm up, convection takes over and the heat that’s on the metal fins is moved through the room naturally.
Since the diathermic oil inside these heaters isn’t needed for fuel, it doesn’t get used up and will remain in the heater as long as you use it.
With this type of design, it takes a few minutes for the oil to heat up and cool down, so the heater only needs to run occasionally to maintain the oil’s temperature. That’s what makes them so energy efficient.
Oil radiator heaters are a very effective type of space heater that can be used in many different locations to keep you warm when the weather gets cold.
Types of Oil Filled Space Heaters
When it comes to oil filled radiator heaters, they all work and are built the same way.
There are no special concerns you have to be aware of when sorting through the best radiator heater options.
Compare that to the best propane heater for house use which has four variations: portable, wall mounted, vented, and ventless.
The only choice you have to make with an electric oil heater is the size you want: standard or mini.
Standard Oil Heaters
These are the taller oil radiator heaters that average around 25 inches in height and weigh around 20 lbs.
They use a maximum of 1,500 Watts of electricity and are good for 150 square feet if used as a primary heat source and 300 square feet if used as a supplement to your house furnace or boiler.
Standard size heaters are the traditional type of heaters people use in the home. They provide enough warmth for the average size room.
Most standard size oil filled heaters include casters (wheels) in addition to a carrying handle to make them easy to move from one room to another.
Mini Oil Heaters
These are mini versions of oil filled radiator heaters that are approximately 14-16 inches tall and weigh around 8 lbs.
They use up to 700 Watts of electricity and can cover about 70 square feet if used as the main heating source and up to 140 square feet if used as supplemental heat.
This is the best heater for personal use.
The most popular ways to use them are under a desk at work to keep your legs warm, in a small bedroom to take the chill out of the air at night, and right next to you in a living room to stay warm throughout the day.
Since mini oil filled radiator heaters are so small and lightweight, they don’t include wheels.
Top Oil Filled Radiator Heater Brands
The oil heater reviews you found earlier in this guide included the top 10 oil filled radiator space heaters you can buy today.
If you’re still not sure which product you should buy, or you want to do a bit more research, here’s a list of the top oil heater brands available today.
Choosing an oil filled radiator heater by any of these manufacturers below will give you the highest quality and reliability for your purchase.
- Comfort Zone
What is the Best Oil Filled Radiator Heater?
The best oil radiator heater you can buy today is the De’Longhi TRD40615E. It includes the most advanced features in a heater as well as the safest design. The patented thermal slots give this heater a lower surface temperature, the Eco Mode makes it energy-friendly, and the digital thermostat lets you dial in an exact degree for comfort.
Heating Capacity vs Room Size
One of the great things about oil filled heaters, which makes them different than other types of heaters, is that they can be used as a primary heat source as well as supplemental heat.
If you’re trying to determine what size oil radiator heater you should get, there’s an easy way to figure that out.
As a Primary Heat Source
Generally, when it comes to using oil heaters for primary heat, every square foot requires about 10 Watts (W).
That means that a 700W heater could heat a room up to 70 square feet:
- 10W x 70 sq. ft. = 700W
And a 1,500W heater would be ideal for rooms up to 150 square feet:
- 10W x 150 sq. ft. = 1,500W
As a Supplemental Heat Source
If you’re using the heater as a supplemental heat source to your house furnace or boiler, then you can get average about 20 Watts for every square foot. Or, essentially double the square footage coverage for the heater.
That means a 700W heater could cover up to 140 square feet:
- 70 sq. ft. x 2 = 140 sq. ft.
And a 1,500W heater would work for up to 300 square feet:
- 150 sq. ft. x 2 = 300 sq. ft.
How to Measure Room Size
Using the simple formula above, you can easily figure out what the best radiator heater size you need for a particular room.
Just measure the length and width of the room in feet and multiply those two numbers together to get the total square footage.
- 15′ x 10′ room = 150 sq. ft.
- A standard size heater would work as a primary heat source and a mini size heater as a supplemental heat source.
- 20′ x 13′ room = 260 sq. ft.
- A standard size heater would work as a supplemental heat source but it would be stretching it to use as a primary heat source.
Features to Look for in an Oil Filled Heater
Even though oil filled heaters only come in two sizes, they still come with a variety of different features.
However, not every space heater has every option, so you’ll need to decide which ones are most important to you and then look for a model that includes them. (See our oil filled heater reviews in the next section for recommendations.)
Those features include:
Most oil filled heaters include two settings (low and high) but some do have three (low, medium, and high). These heat settings relate to the number of watts (W) used, such as 600W for low, 900W for medium, and 1,500W for high.
The best oil filled space heater models include this energy-saving feature. It’s a special mode that alternates the heat setting between high and low to maintain the set temperature. Once that temperature has been met, the unit will automatically turn off. If the temperature in the room drops, the heater automatically turns back on, and once again alternates between high and low heat settings to reach the set temperature.
Each oil heater featured our best energy efficient electric heater reviews page includes this important option.
Oil filled heaters can either have a manual thermostat or a digital thermostat. Manual thermostats use a dial with – to + symbols to control the temperature setting. With this type of thermostat, you can’t be precise with the degree. Digital thermostats let you be more precise in the degree. Some models let you choose between set increments, such as 65, 70, 75, 80, and 85°F, while others let you dial into the exact temperature you want.
This allows you to set the heater to run for a specific amount of time before automatically shutting off. Some products, like our #4 oil heater review, also let you set a timer for it to turn on. This is a nice feature to have if you want to warm up a room at a specific time before you step foot into it.
Having a remote control for your heater is super handy, especially if you use it in a bedroom or living room and don’t want to get up to change the settings.
This feature lets you control the heater from your smartphone. It also gives you the option of setting up daily heating schedules to fine-tune when the heater turns on and off and the precise temperature you want the room warmed to. (See our #5 oil heater review if this interests you.)
Some models have casters that let you move the heater from room to room or readjust the position while using it.
Accidents can happen at any time, and if your space heater accidentally gets knocked over, you don’t want it to turn into a fire hazard. Many models come equipped with tip-over protection to shut it off when it’s not upright.
The heating components inside space heaters get incredibly hot to make the room comfortable. When that happens, it can become a hazard. To ensure that you stay safe, many oil filled radiator heaters come with overheat protection to automatically shut the device off and not allow it to turn back on until it has reached a safe temperature.
Some oil heaters include a ground-fault circuit interrupter (GFCI) function to protect you from electrical shocks. This is especially important if you use the oil filled heater in a wet area like a bathroom. The GFCI component basically cuts power to the unit when the balance of power flowing through the circuit differs from the power returning to it.
If you want to use an oil heater in the bathroom, then consider our top pick for the best space heater for a bathroom here. It offers the most safety features for wet environments.
Benefits of Using an Oil Filled Heater
- Long-Lasting Heat: The oil in these heaters is incredibly efficient and heats up quickly, as well as holds onto the warmth for a long amount of time. The heat continues to radiate out of the heater as the oil cools down, making them incredibly efficient.
- Energy Efficient: Since these heaters heat up and cool down slowly, the room air stays hotter for longer periods of time, even when the unit is not running. This is much different than the fan heaters, which stop heating a room as soon as they’re turned off. Plus, many oil filled heaters have an Eco Mode that uses just enough energy to reach the desired heat and nothing more. This saves you every penny possible on your utility bill.
- Silent: These heaters don’t have any moving parts or fans, so they’re incredibly silent. In many cases, the only way you know an oil filled heater is on is because it has an indicator light or you feel the heat. This benefit alone is what makes oil heaters some of the best bedroom heaters on the market because they don’t disturb sleep.
- Portable: Many of these heaters are equipped with wheels or a carrying handle, which means they’re easy to move from room to room. This gives you the opportunity to take it with you to keep every room you’re in toasty warm.
- Doesn’t Dry Out the Air: Heaters that use fans to blow hot air can dry it out. Oil filled heaters don’t dry out the air because they don’t have fans, the heat radiates off of them.
- Cost: When it comes to the best oil filled heater, not only do you want something that heats effectively, but it also needs to fit into your budget. These heaters are fairly inexpensive, and it’s possible to find models between $50-90, but the total energy savings you’ll get by using them in your home will more than pay for itself.
Safety Tips for Oil Filled Space Heaters
Most oil filled heaters are built to be safe; however, there are some additional things you should consider to make sure your heater doesn’t become a hazard:
- Never Use an Extension Cord: To run optimally, these oil radiator heaters need to draw a specific amount of power, which means they need to be plugged directly into an outlet. This will also reduce the chances of a short circuit occurring or an extension cord catching on fire.
- Never Leave it Alone: Oil filled heaters do take some time to warm up, which may tempt you to leave them alone until the room is hot and cozy. However, like any other space heater, electric oil heaters also come with a fire risk. Since these heaters take longer to cool down, it’s best to stay close so that if they accidentally get knocked over, it won’t char something or cause a fire.
- Choose the Right Location: Since these heaters aren’t equipped with fans, the warm air isn’t blown into the room. Thus, it’s recommended that you place these in a central location in a room so that the warmth can circulate naturally and evenly. It’s still a good idea to put an oil filled heater somewhere where it won’t accidentally get knocked over, which will reduce the chances of it becoming a hazard.
- Give it Plenty of Space: Oil filled heaters don’t turn red like other space heaters, but they will still get incredibly hot. It’s a good idea to keep the unit several feet away from flammable items, which include furniture, walls, and drapery.
- Don’t Use in Damp Locations: If you plan on using your oil filled heater in damp areas such as laundry rooms or bathrooms, you need to make sure you find one that’s rated as being bathroom safe. They’ll come with a GFCI plug. If you don’t get one with this feature, you risk the chance of humidity and moisture damaging the heater’s components or the heater short circuiting. Our #10 best oil filled radiator recommendation above includes this feature.
Cost of Using Oil Filled Radiator Heaters
If you’re wondering how much an oil filled radiator heater will cost you to run each month, you’ll be happy to know that they’re the most inexpensive types of space heaters you can own.
The total cost for using an oil filled radiator will depend on the electricity rate for where you live and the wattage power of the unit.
Each region pays a different cost per kilowatt hour (kWh) of electricity. The national average is $0.13 kWh. You can find your region’s kWh on your electricity bill.
Oil filled heaters use between 400W and 1500W of electricity. The wattage depends on the brand and heat setting you select: high or low.
Keep in mind that the best oil heater models with an Eco mode will cycle on and off so much that they don’t use their maximum wattage every hour.
Calculating Oil Heater Energy Consumption
Once you find the kWh for your location and the maximum wattage of the oil heater, then you can estimate how much an oil filled heater will cost you to run each hour, day, and month.
Use the example equations below as a guideline to find out the most you’d likely pay to use an oil filled radiator heater:
- If your heater has a 1500 watt rating and your cost of electricity is $0.13 kWh, then your cost to operate it for one hour would be $0.195.
- (1500 watts x $0.13 kWh = $0.195 per hour)
- If you run the heater for 8 hours per day, then it would cost you $1.56 per day to use it.
- (8 hours x $0.195 per hour = $1.56 per day)
- If you run the heater 8 hours per day for an entire month, then it would cost you $46.80 in total.
- ($1.56 per day x 30 days = $46.80 per month)
Now, if your heater has a maximum rating of 700 or 1000 watts, then just replace the 1500 number in the above equations to figure out your more accurate costs.
As mentioned earlier in this article, these heaters work by having the heating element heat up the oil, which then holds onto the warmth before it radiates naturally into the room.
The heater turns itself on and off depending on what you set the thermostat to, the temperature of the oil, and the temperature of the ambient air.
Since the oil is so good at holding in heat, it functions as a thermal storage mass, which reduces how long the electric heating element has to operate.
To ensure your heater is working efficiently to lower your current heating bill, you’ll need to turn down the thermostat for your boiler or furnace.
This means that rooms where you don’t have an oil filled heater will get chilly, but those that have this space heater will be cozy and warm.
The great thing about these heaters is that they are portable, so if you’re going into a room that has a chill, you can take the heater with you to heat it up.
Oil Heater vs Electric Heater
Oil filled space heaters are generally more efficient and provide better heat retention than standard electric heaters. Though oil heaters do take longer to heat up, they provide longer-lasting warmth than a fan-forced electric heater.
Also, as we explain here: oil heater vs electric heater, electric heaters are generally much noisier than oil space heaters because of the fan. Oil radiator heaters contain an internal fluid that heats up and stays warm for a fairly long time even after the unit turns off.
Therefore, oil heaters do not have to work as hard as other types of electric heaters to keep a room warm and comfortable.
Oil Heater vs Ceramic Heater
Ceramic heaters can heat up and cool down very quickly, but this also means that these units are hard to keep a steady room temperature without constantly running.
Oil heaters are best for consistent heating and good for warming up an entire room. Most ceramic heaters are better used for spot heating purposes.
How to Use an Oil Filled Electric Heater
Standard oil filled heaters are great at warming an entire room, but they shouldn’t be your primary heat source—especially in the dead of winter.
To ensure the heater is working optimally, you need to find the right size for the room you want to heat.
If the unit is too small, it will work twice as hard to heat up the space. Thus, it’s better if you get a larger heater that uses at least 1,500 Watts.
In addition, instead of getting oil filled heaters for every room in the house, it’s recommended that you only get them for the rooms you spend the most time in.
Remember, these space heaters are portable, so if you’re going into another room, you can easily take the heater with you.
If your main house heating system to 66 degrees, this will reduce how often it runs and significantly lower your heating bill. Then, by adding one or two heaters to only the rooms you frequent, you’ll still enjoy the warmth you need.
Also, if you have a ceiling fan in any room, you can use it to your advantage to make your oil filled heater even more efficient.
All you have to do is reverse the direction of the blades so that they push the heated air down from the ceiling. This can be done with a simple switch on the base of the fan.
Common Questions About Oil Filled Space Heaters
How Much Heat Can an Oil Filled Heater Give Off?
How much heat an oil filled heater produces depends on the type of heater you get. Generally, this is measured in watts (W) and it’s possible to find heaters that range from 400W to 1,500W. A 400W oil filled heater is enough heat for a close, personal space and a 1,500W heater is enough heate for a 150 to 300 square foot room.
Do Oil Filled Heaters Need to Be Refilled?
No, the oil in these heaters doesn’t need to be refilled. The oil is only used to supply the heat and the body of these heaters is sealed tight. That means that the oil will not burn off or evaporate from the heater no matter how long you run it.
Are Oil Filled Heaters Safe?
Oil filled heaters are safe as long as you’re using them correctly, including keeping them away from flammable items. Their job is to heat up a room, so they can get hot, which can make them a fire hazard. However, if the heater is equipped with tip-over and overheat protection, this reduces the chances of them catching things on fire.
Do Oil Filled Heaters Use a Lot of Electricity?
The oil inside these heaters is really good at holding onto heat. Thus, while it takes some electricity to get the oil hot, once it has reached the desired temperature, the heater will automatically turn itself on and off to keep the room warm. Depending on where you live, it may only cost $1.56 per day or less in electricity to use an oil filled heater for 8 hours at a time. This makes these types of heaters incredibly cost-effective.
If you live in an apartment and are looking for ways to lower your monthly bills, then an electric oil heater is a good choice. Several of the models reviewed on this page are also listed on our top apartment space heater guide.
Are Oil Filled Heaters Safe to Leave On Overnight?
It’s not recommended that you leave any space heater on overnight for safety reasons. However, when it comes to oil filled heaters, these are some of the safest options you can buy, especially if they are equipped with overheat protection.
In most cases, as long as they aren’t left unattended or placed near flammable materials, they should be safe to run overnight. It’s also advised that you place them in a location where people won’t trip over them if they get up in the middle of the night.
If you do plan on running any one of the best oil filled radiator heaters listed on this page while you sleep, always use caution and don’t take this advice as an excuse to do it because if something does happen we can’t be liable.
How Long Do Oil Filled Heaters Last?
A good oil filled heater can last up to 15-20 years if properly maintained. By cleaning the exterior columns of an oil filled heater on a regular basis and protecting it from external damages like corrosion, the unit can last up to 20 years or even beyond.
Enjoy Your New Oil Filled Heater
We hope this guide on how to choose the best oil filled space heater was helpful for you in making the choice for your needs.
If you’re still not sure if an oil heater is right for you or just want to see what other types of space heaters are available, you can check out our ceramic heater reviews and infrared heater reviews.
As you discovered in our oil filled heater reviews, these products work differently than other types of portable space heaters.
In particular, the best oil heaters use convection and thermal radiation to heat up a room. They do this by heating up diathermic oil that circulates around inside the unit to create heat that’s slowly released into the air.
Due to this type of heating process, the best oil filled heater can save you a substantial amount of money on your monthly heating bills because these devices don’t require constant energy to produce long-lasting heat.
The best models even include a special Eco Mode to keep electricity costs as low as possible.
With costs aside, hopefully you found the best oil filled radiator for your home, office, or apartment on this list and enjoy it for years to come to stay cozy and warm through the winter.
