The Best Oil Filled Heater Reviews
Now, we’ll be taking a look at different oil filled heater models.
There are hundreds of heaters available, but we made the effort to choose the best of the best! There are seven oil-filled heaters in total that we’ll be looking at. Each of them has its own unique features that might provide you with the best value and performance. You’ll also need to take into account your budget (and find the best heater you can afford based on quality, performance, etc.).
The most recent addition to our best oil filled heater list is also the top model. The KopBeau 1,500W Oil Filled radiator clearly sits above the rest.
The modern design is the first thing you will notice about this model. It would fit in well in any home and doesn’t look like it belongs in the 1980’s like many other designs do.
But good looks isn’t all this heater has going for it. The easy to read digital control panel gives you 3 power settings, as well as the ability to adjust the desired temperature in 1 degree increments – which gives you an amazing level of control over the temperature in your space. It also comes with a remote control, which means you can change the settings from anywhere in the room.
A 24 hour timer is also included, so if you need the heater to turn on at specific times during the day (e.g. before wake up time in the morning) then this heater has you covered.
Efficiency is also important when it comes to heaters and when it comes to cost savings, oil heaters are probably the best. But when you use the KopBeau’s eco mode – it can really help to reduce those home heating bills. The Eco mode will automatically switch between the heater’s lowest power mode and highest mode to keep the room at the desired temperature – at a minimum cost to you.
The only downside we have come across so far is that there is a strong hot/plastic smell when the heater is new, but this dissipates quickly and is not an ongoing problem.
Throw in all the usual safety features, and you have an oil heater that ticks all the boxes.

This means when you turn on the heater, it will still run like normal. You won’t have any kind of failures to deal with because the pipes are frozen or the like. There is probably no other heater on the market that might have something similar to it.
If you are looking for an ideal heater that will start up and run for a long time, this just might be exactly what you’re looking for. With all the features it’s got, it’s hard to say no to it.
How Do Oil-Filled Heaters Work?
As you might have already noticed, this type of heater is powered by electricity. Electric power is used to heat the reservoirs that contain thermal oil. The oil will submerge the entire electrical element and therefore will distribute the heat within a designated coverage area.
For example, a small space heater with 300 square feet of coverage will distribute over 5,000 BTUs of heat. That’s enough to cover a small room. The warmth that is created from the oil will be transferred to the rest of the oil reservoirs.
The oil inside the radiator uses its own heating elements to warm itself up. Inside the heater itself is a system of pipes where oil and liquid transfers usually take place. The good news is these pipes don’t need to be connected to any pipes that may be found in your house.
The heating element located inside the heater itself is a coil made of metal resistive wire. Since the heater is powered by electricity, the electrons will go to work to create friction which in turn generates heat. The wire heats up and then transfers the same heat to the oil inside.
The heat is soon distributed throughout the entire heater unit and then expelled out of the heater where it will heat up the room that it’s placed in. Depending on the size of the heater, the coverage area will vary.
If the heater is smaller in size, it should only be for heating smaller rooms. Likewise, larger heaters will be ideal for heating larger rooms like living rooms, master bedrooms, and so on. Regardless, the process will still be the same.
Heater convection In An Oil-Filled Heater
So you know about the technical stuff about how heaters work. But what about the process where it heats up a room? Let’s talk about convection.
Take a look at the image above, yes – it shows a cooking pot. But the principle of how convection works inside of an oil heater is the same.
Convection is defined as a form of heat transfer that occurs specifically in gases and liquids. This occurs when atoms will flow from one place to the next. The atoms will form molecules that flow in what is known as a convection cycle.
When this happens, warm oil will rise to the top while cooler oil will sink to the bottom. The cooler air will eventually warm up and rise (hence it will be a cycle). This will happen both inside and outside of the heater unit itself.
Oil-filled heaters give off two-thirds of the heat they generate by way of convection. Most of the units are designed with fins to ensure that the heat itself maximizes contact with the air in the room. This finned design is common on most of the smaller oil filled units.
Why You Should Buy Oil Filled Heaters for Your Home
There are different types of heating system that you can get for your home. You can get an electric heater, gas-fired space heaters, boilers, furnaces, and more. So, why should you choose an oil-filled heater? Here are some advantages of the best oil filled heater:
• Adjustable heating level: Most top of the line oil-filled radiators are equipped with an adjustable thermostat for quick and hassle-free heat control. Some even have a remote control for flexibility.
• No professional installation needed: Most of oil-filled heaters come in a portable design and caster wheels so you can move them anywhere around your house. You don’t need to hire a professional to set up this type of heater. No need to rewire and drill!
• Energy-saving modes and safety features: The best oil filled radiators offer ECO-mode for maximum heat output without increasing your electricity bill. Other models also include an automatic shut-down feature in case the oil-filled heater is accidentally knocked down.
• Doesn’t dry the air: Hate heaters that dry the air? An oil-filled heater does not use a fan.
• Low noise operation: Without any equipped fan, you can enjoy maximum warmth without any annoying and irritating sound.
Difference of Oil Filled Heaters and Ceramic Heaters
Ceramic heater uses a convection heating system. Although it can heat up quicker, it also means that it cools down faster. It is also harder to keep the temperature consistent. This is why the ceramic heater is recommended for spot heating only.
Difference Of Oil-Filled Radiator And Electric Heater
Electric and oil-filled heaters need some electricity to produce heat. Choosing between the two boils down to which type of heater can provide you with the best value for the money. If you’re looking for a more energy saving heater, an oil-filled radiator is better.
Choosing the Top Oil-Filled Heater for Your Room
With so many heaters available in the market, choosing an oil-filled heater can be difficult. However, you can make the process less of a chore if you have an idea of what type of heater you should be looking for. We’ll be taking a look at a few things that you need to pay close attention to before making your final purchase.
The following is a list of features to take into consideration:
the Best Oil-Filled Radiator Size for your space
Oil-filled heaters come in different sizes. So choosing the size will depend on some factors. One such thing to consider is your current living environment.
If you are living in a small apartment or house, it makes sense to choose a small heater. However, you may want to get the specific measurements prior to making a choice on which size heater fits you best. A small sized heater is perfect if you have a 300 to 500 square feet room.
If the room you want to warm up is above 500 square feet, that’s when you’ll need to consider the idea of looking at heaters that are larger in size. Space should also be taken into consideration as well.
It would not make a lot of sense to put a small heater in a large room as the coverage area will be limited. Likewise, a large heater won’t fit in a small room because of the obvious reduction in space. Thankfully, the smaller heaters will be easy to place in any corner of your target room (i.e. bedrooms).
Power and Wattage of Oil-Filled Heaters
There’s a good chance that you’ll want to run the heater for longer periods of time. If that’s the case, it’s important to find an oil-filled heater that is energy efficient. This will help you save a ton of money on your electric bill every single month.
Unfortunately, one of the major downsides to owning a heater is it consumes quite a bit of power. And it can cause your energy bill to spike. Particularly, 1500 watts is good enough for you to run a heater for a long time (plus, it doesn’t drain your electricity).
However, the larger the heater, the more wattage and power it will use since it will generate more heat and distribute it to a larger coverage area. This is where choosing the right size will be vital.
Heat and Timer Settings of Oil Filled Heaters
Heat and timer settings are a must-have heater feature. You’ll want different heat levels instead of just one (i.e. low, medium, or high). Timer settings will vary from one model to the next.
The timer’s maximum period of time will vary. Some heaters will go higher than three to four hours and others will have a higher maximum time period like 8 or more hours. The intervals of time will be based on your personal preferences.
The reason why heater timers are included is because it will automatically turn off after time runs out. This will be used to ensure that the heating unit doesn’t run for too long, which can save on heating bills.
The number of heat settings will vary. But more often than not, there will be three. The lower heat settings will conserve more energy while the highest level will use slightly more power.
Safety Features Of Oil Filled Heaters
If there is one thing that many modern heaters must-have, it’s safety features that will prevent the heater from causing a fire. For some reason or another, heaters can get knocked down by complete accident.
If the heater comes in contact with carpets or any kind of material that can easily catch fire, it can spell disaster. Seniors and children may knock it down by accident due to horseplay or limited mobility.
Now, there are features that allow heaters to automatically shut off in the event of it being knocked down to the floor.
Plus, these features will benefit both groups of people the most. In the event of a fire, they may have a hard time evacuating safely. If you are shopping for an oil-filled heater, be sure to give a higher priority to those that have safety features (especially when you have children or senior citizens living with you at home).
How To Use Oil Filled Radiators Efficiently
Now that you have an idea of how you can choose an oil-filled heater based on some of the considerations and features, we’ll show you in this section how to use an oil-filled heater with great efficiency. This is perfect for when you want to save energy as much as possible.
Here are some tips to keep in mind:
Use the timer feature: While you can run the heater all day long, it’s always a good idea to use the timer feature – especially if you want to keep your electricity bill down. Moreover, this feature allows you to set how long the heater can run continuously until it shuts off automatically. As mentioned, the reason for this is to help you conserve the energy that you’ll be using to power the heater itself. Plus, a heater with this feature will save you a ton of money in the long run when it comes to your energy bill.
Leave the heater off when you are not home: This is the equivalent to leaving a light on before you head out the door. You don’t want to leave the heater unattended as it will be a waste of energy. Back then, leaving the heater on would pose as a fire hazard. But thanks to the auto-shutoff feature, that may no longer be a concern. But regardless, it’s better to safely use it than use the heater improperly.
Choose a schedule when you want to run your heater: If you’re going to be home for most of the day, you may want to consider a designated time slot. How long would it be? Morning, afternoon, or night? You can leave the heater on for a certain time slot and turn it off for most of the day. Obviously, the timer feature on your heater will come in handy here.

Frequently Asked Questions
Before you leave, we’ll be taking a look at some frequently asked questions about oil-filled radiators. Use the following questions as a guide so you’ll be able to understand some of the ins and outs of oil-filled heaters and why they are important.
Does an oil Heater need to be refilled?
No. You don’t need to refill the oil heater. That’s because the oil itself doesn’t serve as fuel. It’s used to help transfer the heat from inside the unit in order to help it expel the warm air outward and throughout the room.
Therefore, the oil that is used is never dried up and will never need a refill at all. It makes the maintenance process little to non-existent.
Is it safe to leave an oil heater on?
Believe it or not, you can leave an oil heater on all night. As long as you are there to attend to it, you should be good to go. However, if you are leaving your home you might want to set a timer or shut it off completely to be on the safe side.
But if you want to keep the place warm while you’re gone, there may be no harm in leaving the heater unattended as long as it’s in a low heat setting.
Can oil Filled Radiator cause fires?
In the past, oil heaters have been known to explode due to failing thermal fuses. In the event of this happening, you’ll want to look for potential signs before it’s too late.
Signs to look for include but are not limited to thick black smoke, oil on the walls, unpleasant odors, and any possible surface damage to the heating unit.
Do oil heaters use a lot of power?
Compared to exposed-element heaters, oil heaters use a lot less power. That’s because most heater models use a resistive wire and also have heat sinks that are used to take in any excessive heat.
Therefore, it doesn’t require a lot of power to heat a room even if it’s slightly larger in size compared to others.
How long does an oil heater last?
Despite no need for any major maintenance, the average oil heater should last you anywhere between 16 to 20 years.
As long as the heater coil maintains a temperature ranging anywhere between 750 to 1000 degrees, it will last that long.
Are oil heaters safe for nurseries?
If you have an infant sleeping in their own room, you’ll be reassured to know that oil heaters are safe to run. That’s because these heaters don’t have a surface that will heat up as much compared to other types. An oil heater gets warm, but not so hot that it causes serious burns.
Even if your child is older, these heaters can still be used in their rooms and will mostly be safe to the touch on the surface (unless otherwise instructed by the manufacturer).
Do oil heaters dry out air?
Since they don’t have fans, oil heaters won’t dry out a room. Because of this, oil heaters won’t even make a sound at all. If anything, you’ll hear an intermittent clicking sound coming from your heater from time to time.
This is perfectly normal for most oil heaters and should not be a cause for concern.
Are oil heaters cheap to run?
Yes, oil heaters are cheap to run. Since the need for replacing the oil in this type of heater is non-existent, oil heaters are cheap to run because you won’t need to spend extra money on oil. On top of that, most of them are energy efficient. So you won’t have to worry about a lot of electricity being used up.
The heaters themselves are obviously not that expensive either. If you are looking for a lot of value out of your initial investment, these oil heaters will definitely take the top prize. The low maintenance and ability to run for longer periods safely are two of the best reasons why you should consider getting one.
Are oil heaters better than electric?
When it comes to energy efficiency, oil heaters are indeed better than their electric counterparts. Yes, it will take longer for an oil heater to completely warm up a room. But you won’t have to suck up a lot of energy in the process.
It pays to wait a little longer (as it will be evident on your next power bill). With electric heaters, fast is fine. But there are some issues that people may run into. Such examples include more noise, a greater chance to trigger allergies in the household (especially dust, dander, and other indoor allergens), and of course high energy bills.
Oil heaters may have some issues of their own. But if you can get past the slow heat up time, then an oil heater is probably a better choice than an electric heater.
Do I need a Humidifier When Using an Oil-Filled Heater?
No, oil filled heaters do not dry out the air like some other heater types, and thus you do not need to use a humidifier at the same time.
