You’ll find out what to look for as well as some details about how an oil-filled heater works. We hope that this guide will help you to find the best oil filled heater for your needs.
7 Reasons to Buy an Oil Filled Heater
There are plenty of great advantages to using oil-filled heaters in your home.
- You can save money on your heating bills as you only need to use one heater at a time. Instead of having an entire central heating system in use in your home, you can use an oil-filled heater in the room that you are in.
- Oil-filled heaters take a while to heat up, but they also use electricity effectively. This ensures that these kinds of heaters are as economical as possible so that you can keep your energy bills low.
- With safety features built-in such as overheat protection and thermostatic controls, you will be able to have complete peace of mind when you are using your oil filled heater.
- Most oil-filled heaters can be moved from one room to another. This can be a convenient way of saving money as you can simply take the heater with you to use in another room. This means that you’ll only need to buy one heater.
- Programmable timers allow you to set the heater to turn on at certain times in the day. This will save you money whilst ensuring that the heater has had enough time to warm up. Use the timer to make the heater turn on before you arrive home from work, for example, to ensure that you come home to a comfortable heat.
- Instead of having a blower to distribute heat around your home, your oil-filled heater will use convection heating methods to distribute heat. You will need to ensure that you allow enough clearance around the heater in order for the heat to be distributed evenly. As long as you have enough space, you will find that the heat from an oil-filled heater is far more comfortable than that from a fan-forced heater
- These heaters often come with a warranty so that you can rest assured that your heater will last you for many years.
Top 5 Things to Consider Before Buying an Oil Filled Heater
Is An Oil Filled Heater Right for You?
Before you even begin looking for the right oil filled heater for your needs, you should make sure that this will indeed be the right type of heater for you. There are sometimes when these heaters are not suitable and in these cases, you should look into the possibility of choosing a different kind of heater.
If you have a smaller room with no draughts, then an oil-filled heater will be perfect, but if you have more space to heat such as a garage, you should certainly think about an alternative option like the best garage heater.
Oil-filled heaters rely on convection currents to heat an area so if there is too much air to warm up, you are unlikely to feel the benefits if you have a room that is too large.
In addition, garages aren’t usually well insulated and as a result, these are probably not the best environments in which to use an oil-filled heater. The heat will most certainly escape into the areas of your garage when there is a draught. You should also be wary of choosing an oil-filled heater if you are concerned about heaters that become hot to the touch. Oil-filled heaters do become very hot when they are in use.
Find the Right Size Oil Filled Heater
Buying an oil-filled heater should involve making sure that the model that you choose will be sufficient for heating your room. You should ensure that you take correct measurements of each room that you will be using it so that you can calculate how much heat output the heater will need to produce.
Measure the length and width of your room in feet and multiply these values together. This will ensure that you know how many square feet your room is. Most of the oil-filled heater product descriptions that you’ll find online will give an indication as to the size of the room that the heater will be able to warm up. You should remember however that this value will be under the best possible conditions and won’t allow for draughts and poor insulation, so you should try to choose a heater that can warm up a slightly larger area than you need.
You should also ensure that the heater will be the best size for your room. If you don’t have much space to stand a heater, you should choose a more compact size. Remember that the smaller the heater, the hotter the surface temperature of the heater is likely to be as the heat can’t be dispersed over as large a surface area.
Decide on a Design
When you buy an oil-filled heater, you should make sure that there are enough safety features to make it as safe as possible whilst you are using it. The design of the heater is important because this will ensure that the heater does not become too hot whilst it is in use. Heaters that are designed with longer heating tubes and wider fins allow the heat to spread out over a larger surface area. You should always look for the heaters that have taller fins. These will be cooler to the touch than their smaller counterparts whilst still producing the same amount of heat for your room.
If you want to move the heater from room to room with ease, you will need to ensure that you’ll be able to do so. Some oil-filled heaters come with wheels so that you can conveniently wheel them around. You should also look out for heaters that have plastic handles at each end as they will be safer to move if you need to. You should try to avoid moving oil-filled heaters if they are still hot to the touch.
More fins mean more surface area. Therefore, you should try to find heaters that are made with more fins if possible. This will again let the surface temperature stay low and it may even make the heater more powerful than an alternative model.
If you want a really stylish oil filled heater for your home, you should be able to find plenty of designer oil-filled heaters. You can even find heaters that can be mounted on the wall. If you are trying to concentrate on the look of the heater, however, you should try not to get distracted by focusing too much on design. Remember that there are other more important factors that you should be looking out for.
Smarter Material Choices
When you choose an oil-filled heater, you should ensure that it will be as durable as possible. You will be able to find heaters that have been made with different types of materials and that have been made in a different way to the next heater. If you can identify the best quality method of creating a safe heater, you’ll have more chance of choosing the best one for your needs.
You should look for a heater that is made of steel. Steel is strong and durable whilst also being easy to maintain and keep clean. It will also not rust. To further protect against rust, many of the better heaters have an enamel coating. Enamel is strong and will not flake easily. Again, it is easier to clean.
The more fins that there are on the heater, the more chances that there are for something to go wrong. You should look out for heaters that have been machines welded for strength and prevent leaks. Oil-filled heaters should never leak and they can be dangerous if they start to leak out.
Check Your Warranty Status
Whilst a warranty may not be a deciding factor when you are looking for a great oil filled heater, it should still be important to you. Consequently, you will have some protection against your purchase for a certain amount of time. Oil-filled heaters can be relatively inexpensive if they fail within their first year or two. If you have no warranty, then it could be unnecessarily costly to need to replace the heater.
Some companies offer a standard 1-year warranty. This will mean that the manufacturer will repair or replace the heater if it develops any problems in the first year. If you use the heater often enough, you will find that any faults that may develop after purchase will usually occur in the first year after purchase.
Often, a 1-year warranty will be all that you’ll need. For a little more peace of mind and a way of guaranteeing that you will have a working heater for a few years, you could choose a model that offers two or three years of warranty.
Obviously, the longer the warranty, the better. You should also be aware that the kind of warranty that is offered will differ from manufacturer to manufacturer. A limited warranty will usually only cover certain aspects of the heater. You should read the small print that comes with the product to find out what level of warranty you’re being offered.
Otherwise, you will worry about why your oil filled heater has stopped working and how to solve it.

Oil Filled Heaters Vs. Ceramic Heaters
When you buy an oil-filled heater, you will be able to enjoy many great benefits such as longer-lasting heat and a comfortable temperature in your room, but how do oil-filled heaters compare to ceramic heaters?
Ceramic heaters are usually lighter in weight than oil-filled heaters. This is because these heaters do not have any liquid weighing them down. Oil-filled heaters, on the other hand, are far heavier as they are filled with oil and feature fins that spread the heat across the area of the heater.
When you turn on a ceramic heater, it can warm up quickly. If you want instant heat in your room, then these kinds of heaters are a perfect choice. On the other hand, once the ceramic heater has been turned off, it will be cold instantly. This isn’t the best use of energy. Oil-filled heaters have to warm up before you can benefit from their heat. However, once they have successfully heated up, you will be able to enjoy warm air for longer. This is because the oil retains heat better than ceramic heaters. You will need to take extra care around oil-filled heaters as they become very hot to the touch.
Do You Need to Refill Oil-Filled Electric Heaters?
Although it is true that oil-filled heaters are indeed filled with oil, you do not need to worry about them needing to be refilled. When you use the oil-filled electric heater, electric heats up an element, and then the oil is heated by the element. The oil then circulates around the fins of the heater.
Because there is no combustion reaction, no oil is burned when these heaters are turned on. This means that the level of oil will never drop. You will never need to refill the oil as a result.
Oil-filled heaters are made to be tough and durable. They are also designed so that the temperature of the oil can’t be high enough to cause the heater to burst. Your oil filled heater should never start to leak as a result of this.
If you notice anything different about your oil filled heater, such as a strange noise like there is a lot of air in the heater or if you notice that the heater is leaking out any fluid, you should turn it off immediately. Unplug the heater and ensure that you either throw the heater away and buy a new one or call a professional who will tell you if it is possible to fix the heater.
6 Ways to Keep Your Oil Filled Space Heater Running Safely and Efficiently
As with any electrical heating appliance, it is important that you take care when you are using oil-filled heaters in your home. Although they are designed to be as safe as possible, you should bear in mind these safety tips when your heater is on.
- It can be very dangerous to use any heater with an extension lead. You should always try to plug your oil filled heater into a plug socket. If this isn’t an option, you should ensure that you purchase a high-quality extension lead that can handle the load on your heater.
- Heating up oil makes these heaters potentially hazardous if they are not wired up correctly. If you are buying a new oil-filled heater, you should ensure that it has safety certification. Also, you should always purchase from a reputable source. In addition, it is important that you buy a new heater as there is no way of knowing how safe a used heater will be.
- You should never try to repair or open up an oil-filled heater. If your heater is expensive, you could contact a professional who may be able to repair and service your heater. On the other hand, most oil-filled heaters are very cheap these days and it is usually safer to replace them.
- Remember that the heater will certainly get hot when you are using it in your home. Thus, you must keep it free from any obstructions. Do not use the heater to hang laundry on to dry and do not let children or pets near the heater to avoid injury.
- When you are not using the heater, you should ensure that you switch it off and unplug it.
- Ensure that you do not alter the thermostat with any tools as doing so could lead to the unit overheating.

How Oil Filled Heaters Work
An oil filled heater looks like a standard radiator that you may expect to see in older buildings. These kinds of heaters are far smaller, though. The heater is made up of fins that are joined to one another and they often have an open space in between each of the fins. A control panel at the front of the heater allows you to control it. In addition to the fin style models, you can also find these kinds of heaters that are made up of a single panel.
Oil-filled heaters are usually made to be portable and they plug into your home’s electric supply using a standard plug. So, here is how electric oil-filled heaters work;
Electricity enters a resistor within the heater and is converted into heat. This warms up the oil in the heater. As the oil begins to warm up, it circulates around the design of the heater.
The moving heat is transferred and spread over the fins, giving the heat a larger surface area to escape from and this heat begins to radiate out into the room using convection currents. As there are no fans, this kind of heater is particularly quiet and they require very little maintenance. All you’ll need to do is clean off any dust each week so that dust doesn’t accumulate in the fins of the heater.
Guidance for the Use of Oil Filled Radiator Heaters
Although oil-filled heaters are great to use as supplemental heating in your home, there are some environments where these heaters are more suitable than others.
If you have a smaller room to heat up, then this kind of heater will be ideal. You will be able to enjoy soothing and even heat that is distributed throughout your room to provide comfort when you need it. You should avoid using these heaters in less suitable spaces such as garages, however. They will simply be a waste of energy.
Oil-filled heaters are more suitable for use in homes that don’t have small children or dogs. These heaters become incredibly hot to the touch. Even the ones that take measures to be as cool as possible when they are in use can still have the potential to cause burns. If you have small children or pets at home, you should consider choosing a different heater.
If you want a portable heating solution that allows you to move your heater from one room to another, then an oil-filled heater is probably for you. However, you will have to wait for your heater to cool down before you move it. The heater will be hot to the touch and will be dangerous to move when still warm.
1. Do Oil Heaters Use a Lot of Electricity?
They don’t really use that much electricity, at least not more in comparison to other types of heaters. They use the same as a conventional space heater in general, respectively 1,500 watts. The good thing is that these heaters come with some special settings that allow you to determine how much electricity the heater is going to use. Simply put, you can set the device for the lowest setting, which will consume less than 1,500. This feature allows you to save on energy and the costs that come with it since the power also goes into the oil and not in the air.
2. How Much Time Does an Oil Heater Take to Heat a Room?
The answer depends on the overall size of the room and the power settings you use to perform the warm-up. Usually, the larger the room, the longer it will take for it to heat, but this time frame may also be reduced if you use the device at its highest settings. If you have a room at about 150 square feet, then 15 minutes may be enough to warm the room. If it’s larger than that, the amount of time will increase, of course. Make sure to check the size of your room, because only then will you be able to make a proper estimation.
3. Why Do Oil Heaters (Room Heaters) Have Fans? Do They Burn Oxygen, Too?
Heating up a room with an oil radiator is not the fastest process. This is one reason why these heaters are provided with a fan. In order to make sure you’ll enjoy the benefits of this device much quicker, fans are used to spread the warm air throughout the room.
As for whether they burn oxygen or not, the answer is no. Such a device uses oxygen to spread the hot air in the room, but it doesn’t burn it. It is essential to turn off the fan of the heater once the room gets warm – at least that’s the case with some models. The oil will do enough to maintain a warm temperature.
As you can see from this useful buying guide, there are all kinds of great oil-filled heaters out there for you to choose from, with plenty of advantages to enjoy when you do use them.
They are a convenient and portable solution when you want the heat in the winter months. Also, they will mean that you won’t need to turn on your entire heating system in order for the room to be comfortably warm. You will also be able to buy an oil-filled heater and use it immediately as they don’t require any assembly or installation. Simply plug the heater directly into a plug socket and it will be ready for use.
These useful oil filled heater reviews are a great way to find out about some of the models that are out there. We hope that you’ve also found this buying guide helpful in choosing the best oil filled heater for your home.
