How Do Oil Filled Heaters Work?
As you might have already noticed, these oil-filled heaters are 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 heaters are 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 smaller rooms. Likewise, larger heaters will be ideal for larger rooms like living rooms, master bedrooms, and so on. Regardless, the process will still be the same.
A lesson in convection
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 principal of how convection works inside of an oil heater is the same.
Convection is defined as a form of heat transfer that occurs when 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 rise and warm up (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 content with the air in the room. This finned design is common on most of the smaller oil filled units.
Choosing The Right Oil Filled Heater
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 you’re 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:
Choosing the Size of Your Oil Filled Heater
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, you may want to get the specific measurements prior to making a choice on which size heater fits you best. A small sized heater will be perfect for rooms that are measured from 300 to 500 square feet.
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
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 some heating units is that 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
Heat and timer settings are a must-have 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 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 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 get excessive in temperature. At the same time, it’s also useful when you want to conserve energy.
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.
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 they come in contact with carpets or any kind of material that can easily catch fire, it can spell disaster. Now, there are heaters that will automatically shut off in the event of it being knocked down to the floor. Seniors and children may knock it down by accident due to horseplay or limited mobility.
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 must find 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 Heaters 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 it all day long, it’s always a good idea to use the timer feature. That’s because you can set it to how long it can run continuously until it shuts off automatically. The reason for this is to help you conserve the energy that you’ll be using to power the heater itself. Plus, it will save you a ton of money in the long run when it comes to your energy bill.
Leave it 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 it improperly.
Choose a schedule when you want to run it: 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 it on for a certain time slot and leave it off for most of the day. Obviously, your timer feature will come in handy here.

Frequently Asked Questions
Before you leave, we’ll be taking a look at some frequently asked questions. Use the following questions as a guide so you’ll be able to understand some of the ins and outs about oil-filled heaters and why they are important.
Here are the following questions:
Does an oil filter need to be refilled?
No. You don’t need to refill the oil filter. That’s because the oil itself doesn’t serve as a 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 it unattended as long as it’s in a low heat setting.
Can oil heaters 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 its 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 heaters 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 coil maintains a temperature ranging anywhere between 750 to 1000 degrees, it will last that long.
Is oil heaters safe for nurseries?
If you have an infant sleeping in their own room, you’ll be glad 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. It will be safe for a child because it provides them with plenty of warm air that won’t burn or cause any type of harm.
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, these 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. Since the need for replacing the oil 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 they pale in comparison to what electric heaters have. To sum it up, oil heaters do way better than electric.
