Ever have thought, is there any space heater that can run, causing the least amount of dehumidification?  

Such a space heater that never allows you to feel a dry nose after continuous running?

The best oil filled radiator or oil filled space heater, whatever you call it, that’s the ultimate solution.

Oil filled space heaters are the healthiest option for heat up your house, living room, nursery, household garage, motor-homes and anywhere you want.

At the same time, oil-filled radiators are electric efficient and safe home appliances so that you hardly can complain about them.

Best Oil Filled Space Heater – Quick Picks

But to ensure quality, better durability, and most importantly, to suit all your necessities, the best oil filled space heaters must have to fulfill some criteria.

In this article, I have discussed each and everything you need to learn about this appliance so that you can enjoy a charming winter each year.

Must Ensure these facts before choosing a new Oil Filled Space Heater

How much wattage of Oil Filled Space Heater do I need? 

How large is your space? Choose the radiator’s size and wattage according to your room. 

Most of the radiators consume 1500 Watt during max heating setup. But the important part is, What’s the “MINIMUM SETUP” consumption?

Some heaters offer a 600W minimum watt consumption and some other offers 900W. 

If your space/room is below 100 sqft, then go for those radiators with a 600W minimum watt setup. But if your room size is around 120-150 sqft, you should choose the radiator with a 900W minimum watt setup.

The most brilliant idea will be choosing those Oil Filled Space Heater that has 3 heat setup of Min 600W, Mid 900W and Max 1500W. This choice will allow you to use the radiator where ever you want.

Note: If you require a radiator for narrow space or want to run that unit by generator power, you should choose the 1200 watt unit of Comfort Zone (My last reviewed item). 

Is your preferred Oil Filled Space Heater have portability?

Oil Filled Space Heaters is giant, and most of them have a minimum of 20 Ibs weight. So most of them offer caster wheels at the bottom. 

But not all models have that feature, and the holder/handle for pushing or pooling is not comfortable for every single unit.

You should ensure your preferred model has caster wheels, and the holder is placed at the correct, comfortable position, and the unit has a coil holder. So you can move the unit quickly wherever you need.

Ensure your preferred Oil Filled Space Heater contains all safety features!!!

Mainly the radiators include tip-over safety and overheat protection.

You should ensure that your preferred model fulfills these features, and some additional would be better.

Some oil-filled radiators have enamel-coated body color to protect them from rust and keep down from being too hot to touch. 

Additionally, please make sure the power cable is at least 6 feet long so that it can reach your electric outlet easily.

Oil Filled Space Heater should contain ECO mode & Timmer.

ECO Mode of Oil Filled Space Heater Explanation: When you turn the ECO mode ON, the radiator automatically shifts between LOW, MED, HIGH heating set up to hold the preset temperature maintaining the most energy efficiency level. All units don’t contain this feature.

Importance of Timer: Oil Filled Space Heaters are very quiet, so it remains unnoticeable while running. If you set the timmer, the radiator will turn OFF automatically after a while. But if your preferred model does not have this feature, the unit may run overnight if you forget to turn it off.

Does your Oil Filled Space Heater contain a digital display & Thermostat?

These days, all the appliances are getting turned into digital operations instead of manual knobs from the old days. Electric Oil Filled Space Heaters are following the same trend.

Most of the radiators are offering digital displays with digital thermostats & remote control. These features will help you a lot to operate the device and maintaining the exact temperature that you do want. 

Most importantly, the remote control is essential to me as I won’t like leaving the bed to change the room temperature during my sleeping schedule. 

How many Fins does your preferred Oil Filled Space Heater contain? 

Fins work as a heat exchanger for Oil Filled Space Heaters. Most of the radiators contain 6 fins; very few models have 7 fins. Although this is a minor fact, remind the thing, the more, the better.

Building Materials of the radiator, are they long-lasting?

Mostly the radiators are made of stainless steel. I never have hard of old radiators that have become rusty. So I don’t think you need to be worried about this. 

But, enamel coating is a must for these machines. Cause high temperature burns the exterior in the long run. Enamel coatings are a heatproof layer that increases the unit’s longevity and protects the user from having heat shock.

Warranty – Of Course, the longer, the better!!!

Most of the oil filled radiator company offers a 1-year warranty. But I have covered two unique radiators that have an extended 3-year of warranty.

Pricing- How expensive should be an oil filled radiator?

The minimum price was USD 44 on our reviewed list, and the maximum price is USD 239.

USD 90-100 is the best budget range for oil filled radiators; I have covered several models from these price ranges if you have checked.

Who should choose oil filled Space Heater?

Here are some specific criteria or types of people who should consider choosing an oil filled space heater instead of infrared or electric ones.

Have allergies? Let the Radiator take care of you.

An oil filled radiator can massively benefit those people who have dust allergies, heat allergies, and stuff like that. Why?

Radiators don’t contain a fan. It doesn’t circulate the air inside your room that contains dust particles. So there is no chance of any molecular movement due to running the oil filled radiator inside the room.

Again, the radiator generates heat by heating up the inner diathermic oil. Then the fins exchange the heat with room temperature. So the warmth is soft and comfortable for sensitive people. 

Have large rooms? Then Radiators would be the best choice!!!  

Large rooms require massive energy to raise the inner temperature, which is too energy-consuming. Inside a radiator, the oil holds the temperature and radiates it to the room climate through the heat exchanger called fins.

Additionally, radiators don’t require any fan or motor to circulate the air. So at the end of the month, it saves a ton of electric bills.

Do you Search for Cheap operation cost?  

As I have said, oil filled radiator doesn’t require any fan to circulate the hot air forcefully. Thus it saves a ton of energy and uses it to generate heat instead.

Additionally, most of the oil filled radiator has an eco mode to distribute power smartly. This feature allows the radiator to consume energy according to demand. So it does reduce a lot of operational costs.

Want to sleep turning the heater ON overnight?

This is another advantage that you can only get from a radiator. Oil filled space heaters work noiselessly. So there is no reason for disturbance during bedtime. 

Additionally, automatically the heater gets turned off once it raises the room temperature at your preset level. Thus it maintains a constant temperature the whole night.

Finally, you will find a timmer to turn off the radiator at your desired schedule. So you may go to sleep keeping the heater ON without any worry. 

Have newborn babies? The radiator will be the best carer!!!

 Baby skins are too soft and get dry very quickly. To hold the moisturizer, we do care a lot.

Oil filled radiators are the best option to heat the room with the minimum amount of dehumidification. Of course, you should use a humidifier in your baby’s room but, the radiator heaters do a very minimal amount of dehumidification which is very beneficial for the skin.

You won’t feel a dry nose while running an oil-filled heater in your room.

Why should an oil filled space heater be your PRIORITY PREFERENCE?

By preferring an oil filled radiator, not only you are making ownself benefited but also helping the environment to make it healthier

  • The oil remains wholly sealed inside the radiator and consumes heat from the heating elements, then transmits the heat to the room climate using fins. No CFC like heat pumps (AC), no burning fossil, no harsh IR radiation. So at a time, this is beneficial to you and the environment.
  • The heat that is generated from oil is soft and silky. So it doesn’t de-moisturize the skin and doesn’t dry your nose and throat. 
  • No white noise of fan motor, you can enjoy a healthy night’s sleep silently.
  •  Oil filled radiators are the most economical choice due to lower electricity consumption.
  • Oils hold the heat for a very long time; if you shut the heater down, the oil will radiate heat for a couple of hours after that.
  • An automatic thermal cutout system ensures holding the exact room temperature you need.
  • The oil is permanently sealed. No worry about changing or refill the oil at all.

Some safety tips to know before you buy an oil filled Space Heater

  • No Extended Wire: Oil filled radiator is a high-watt consumer. Try to plug in the power cable directly on the socket without any multiplug or extended wire. In case you hardly need it, then find some wire capable of supplying 15amp current at least.
  • What If Leakage?: If you find any oil leakage, don’t handle it ownself. Call a professional and fix it entirely before using it again.
  • Want to Leave it ON the whole night?: Instead of leaving it ON for the entire night, use the Timer. It will automatically turn the heater off after 10 hours or as you want.
  • Keep your Tarzan Toddler Away!!: Toddlers are curious; they want to touch everything. The outer surface remains hot during operation. Teach them it’s hot to touch to avoid heat shock.

9 Best Oil Filled Space Heater Radiator Reviews


1. Best Oil Filled Space Heater for Large RoomPELONIS-NY1507-14A

Pelonis portable oil filled radiator space heater ! 1500W

2 Heating Setup – Low 900Watt, High 1500Watt

Warranty – 1 Year

Remote Control – Yes

Heating a large room wasn’t that easy and energy-efficient until we found the Pelonis NY1507. Relying only on a central heating system isn’t a wise choice. 

But a large room requires massive heating capacity. Pelonis NY1507 electric Oil Filled Space Heater can amazingly heat an isolated large room remaining energy efficient.

Digital Controls and several intelligent features have made it unbeatable to other competitors. Although, you should not choose this unit for small rooms as its low heat setup is 900W while some others are offering 600W for low setup.

My Favorite Features

Digital Controlling System: Pelonis Ny1507 is offering an entirely digital controlling feature. You are allowed to choose five different temperature setup 65F, 70F, 75F, 80F, & 85F, and auto shut down timer in five further delay 2H, 4H, 6H, 8H, 10H.  

Additionally, you will enjoy the super-fast heating experience with a 1500W high and 900W low power setup. 

ECO Mode: Let’s boost up the energy efficiency level with a single click. Turn ON the eco mode, and the heater will shift between Low/High set up automatically according to its requirement. So you will get the fastest heating at the lowest cost.

Remote Control & Safety Features: Pelonis comes with remote control with a battery. The battery remains sealed with plastic paper; for the first time, you need to remove that. The remote is super handy!!! But a bit tiny. You may use velcro to attach it to the wall.

Pelonis has “overheat protection” and “tip-over safety” to shut OFF during accidental knock-over instantly. 

Wide caster wheels enhance portability, and 6 feet long wire can reach anywhere in the outlet.  

Note: Pelonis consumes around 14 amp current while running on a high setup. If you do require it, then install a 15 amp breaker for hassle-free operation.

Something I didn’t like

  • Louder Beep Noise during every button press. Really too loud!!!
  • Temperature settings have a 5-degree breaking point—if you are running on 70F, no way to raise it on 73F. You have to go on 75F.
  • You can’t choose 1,3,5,7,9 hours timer. Only 2,4,6,8,10 can be selected.
  • The power cord is placed at the front.

It sometimes stinks when running on high.

Frankly, this Oil Filled Space Heater is my personal preference. If I would have to buy a unit, I would straightly choose this one.

Misconception Revealed!!! Does it require oil to run an Oil-filled Space Heater Radiator?

You never ever need to refill oil inside the oil filled radiator. I mean never at its lifespan. The oil remains entirely sealed inside the radiator.

How does it work? Well, the heating elements raise the oil temperature inside the radiator. Just similar to your water heater, how it does heat up the water and raise the temperature to the boiling point. 

Then the oil circulates through the fins, and the fins work as a heat exchanger as they transmit the temperature to the room’s climate. 

Then why the radiator use oil instead of water? Oil consumes heat far faster than water. As a result, you can enjoy the warmth instantly. 

Some drawbacks of oil filled radiator that you should know before buying one.

  • Heats Slowly!!! As the radiator first raises the oil temperature, and there is no fan to circulate the heat towards the room, you will experience a bit of slow heating with a radiator. You may use a small table fan behind the fins to accelerate this procedure.
  • Large in Size!!! Oil filled radiators are bulky and heavy. It will be hard for you to carry here and there.
  • Hot Surface!! Touching the interface while running the unit won’t be a wise choice to make!!! Stay away, kids!!!

Comparison Between Oil Filled vs. Infrared vs. Ceramic Space Heaters  

If you are a bit confused about choosing a space heater and thinking which type would be the best suitable solution for you among oil-filled, infrared, and ceramic space heaters then, this paragraph may help you have a clear decision.

Oil Filled vs. Infrared which one should I pick?

The infrared heating system is mostly a personal heating solution. Where infrared filament produces the temperature, and a reflector transmits the heatwave towards a particular direction.  

If you do any “desk job” or want to feel the warmth in a particular space where you are working, then an infrared heater would be a good selection. It won’t waste energy heating the entire place but only where you need it.

On the other hand, the oil filled radiator is effective in heating the entire room. So what do you want? Want Heating the whole room or the only section of a room where you do work or watch TV sitting on? 

Oil filled vs. Electric Ceramic heater, which one should I choose among these?

This is a tricky question as both of them are being used for the same purpose.

Then you may think of the user’s type. Who will be the user? Your kids, Grandparents, or your own self? 

Kids and old persons have sensitive skin and need to be more moisturized. As the oil filled radiator can run doing the least amount of dehumidification, it would be the best choice for sensitive users. But keep in mind that this heater works slowly.

On the other hand, if you don’t care about dryness and need a fast heating solution, you may choose an electric ceramic heater for sure. In that case, you may use an additional humidifier.

What is the operation cost of an Oil Filled Radiator?  

 We experimented 3 nights with a 1500 Watt oil-filled radiator with 3 different modes to precisely measure this fact.

Note: The environment temperature was around 50 degrees F, and the room we experimented with was 144 sqft (14*10) and well insulated entirely.

As for the power meter, we have used the Ponies PN2000 watt meter, and here is the result we got.

First Night (1500W Max setup):  

  • Environment Temperature: 50 Degree F
  • Heater’s preset Temperature: 75 Degree F

The heater consumes 1500 watt/hour = 1.5 KW/hour

So on 2.734 hours it will consume 2.734*1.5 = 4.09 KWhr

So per day it will consume 4 KWhr or 4 Unit electricity. In America per unit electricity cost is 0.1313 cents.

So per day it will cost 4.09*0.1313 = 0.58 Cents

So at the end of the months it will cost 0.58*30 =  $16.14

Unit Calculation

414 min = 6.83 Hours

The heater consumes 600 watt/hour = 0.6 KW/hour

So on 6.83 hours it will consume 6.83*0.6 = 4.09 KWhr

So per day it will consume 4 KWhr or 4 Unit electricity. In America per unit electricity cost is 0.1313 cents.

So per day it will cost 4.09*0.1313 = 0.58 Cents

So at the end of the months it will cost 0.58*30 =  $16.14

NOTE: Have you realized? Low wattage doesn’t means a lower electric bills?
