How to Pick the Best Oil Filled Radiator Heater
You can find hundreds of different oil space heater units on the market these days. It doesn’t come as strange then that you are having trouble choosing a suitable model for you. Take a look at these tips and make your purchase a piece of cake:
Bring the Power…
The first thing to keep in mind is the potential heat output of your heater. The wattage is what determines its strength. This can vary from 500W to as high as 3000W. The capability of heating a room increases with the potency of a heater. Aside from that, you should also consider its size. Oil filled heating appliances are radiant devices. That means the surface of the heaters emits the heat. Therefore, large-sized heaters have better capability to warm up space around it.
…and Then Put It under Control
It’s nice to have sheer power and abundance of heat, but it is crucial to be able to tailor it any way you want. That is why options for heat settings are equally important as the strength of the heater. Most of the oil filled heating appliance has several different heat settings. For example, a standard 1500W heater might have three functions – low (500W), medium (1000W), and high (1500W).
The option to choose the heat output helps you find the perfect temperature for your room. However, it also enables you to maximize the oil filled heater efficiency and decrease overall running costs.
Can You Move It Around Easily?
The majority of oil filled heaters available on the market today is portable. However, don’t think that you can pick them up and take them to the other room just like that. These heating appliances are heavier and bigger than other types of heaters. That is why they are equipped with casters that enable them to mobility. If you want to use the unit in multiple positions, we suggest looking for a model that has durable wheels and can be moved around quickly.
Stay on the Safe Side
Safety features should also be your primary concern when choosing an oil radiator heater. The standard additions should include tip-over safety and thermal overload protection. You should also pay attention to the edges because they are sharp in some models. Look for units with rounded corners to ensure that they are not a threat to anyone, particularly pets or children.
Read the Warranty Info
If the manufacturer offers a warranty on the product, it is an indicator that they trust in their creation. It really is that simple. That is why you should always read the warranty info. It should guarantee that everything will work properly for at least a couple of years, although some manufacturers provide even 10-year warranties.
Is It Pretty?
The last thing to consider, but it’s not the least important. You don’t want to buy an ugly model that will disrupt your home decor completely. Instead, you want to find a model that is visually appealing and contributes to the overall design of the room.
How Does Oil Filled Heater Work
Although it is self-explanatory, a lot of people still fail to understand how oil burning heater works. Let’s try to solve all dilemmas and offer an explanation of oil heater system.
If you take a look at one of these heating appliances, you will see that they have several metal columns. The oil can spread freely across these columns, and that is the basic mechanism of the oil filled heater.
If you take a look at the base of the unit, you will find a heating element there. This component is in charge of warming up the oil.
The hot oil then flows throughout the unit and spreads the heat. Next, pay attention to the fact that there is a cavity after each metal column. That is how warmth can be radiated through a larger surface, and that increases the efficiency of the product.
The common misconception is that these heaters don’t need electricity to work. That is not true. They need to be plugged into a power outlet to start the heating process. The energy is then used to heat the base of the heater, which in turn warms up the oil.
These are the basic steps of the oil filled space heater mechanism:
- Electricity heats the warming element at the base.
- The warming element heats the oil.
- The oil uses convection to transfer heat to the metal wall and conduction to pass the warmth through multiple walls.
- The air is heated via radiation and convection, and that is how the temperature in the room increases.
Keep in mind that oil is not used as fuel. That doesn’t mean that you are required to replace it every now and then. In fact, you don’t have to change it at all. As long as everything works correctly, the oil volume will be at the same levels for years.
Some of the Common Q/A about Oil Heaters
I’m sure you have a lot of questions hanging about oil radiant heaters. Let’s take a look if I can answer some of them immediately:
How Much Does It Oil Filled Radiator Cost To Run?
It’s hard to give a definite answer as it depends on the amount of time you leave it on and the heat settings you choose. However, if you use standard heat settings for three or four hours a day, a single oil filled radiant heater probably won’t cost you more than $50 a month.

Can You Get Carbon Monoxide Poisoning from Oil Heaters?
An oil filled electric heater burn oil. Instead, it only uses it to distribute heat. Therefore, it doesn’t produce carbon monoxide, and there is no danger of getting poisoned.
Are Oil Filled Heaters Expensive to Run?
It depends on how long you keep them on, which settings you use, and what your definition of expensive is. However, with the right usage, oil heaters can be extremely efficient and affordable to use.
Are Oil Heaters Energy Efficient?
Yes, they are nothing but energy efficient. In fact, more than 99% of the electricity produced goes directly into the heat, and there is no energy wasted. Aside from that, if you compare the heaters to a regular furnace, it utilizes far less power. Add to that the fact that you can quickly move the unit from one location o another and you get a unit that is worth investing.
How Much Does It Cost to Run a 500W Oil Filled Radiator?
There is a simple calculation that you can use to find this information:
Power (kW) X Running Time X Electricity rate = Price
Power is nothing else than your heater’s wattage expressed in kW. So, if you use a 500W heater, that would mean it utilizes the power of 0,5kW (1,000W = 1kW.)
Running time is an average amount of time per day/week/month you use your heater. Let’s say that you use it for three hours per day. As for the electricity rate, you might need to look at your utility bill to find this piece of info. Let’s say for this example that it is 0.122kW/h.
So, the equation for a 500W oil filled radiator would be:
0.5 x 3 x 0.122 = $0.183
That means you would be paying $0.183 daily for running your heater as long as you use it three hours per day at the 500W settings.
What Is Better Oil Heater or Electric?
Both options can do a solid job in heating up the room. Electric heaters tend to be lightweight because they use only electricity to warm up the area around them. As such, they tend to be noisy, and they cool down quickly if you unplug them.
Unlike that, oil heaters need a bit longer to warm up, but they can remain hot for a while even if they are not plugged into a power outlet. That enables them to be more efficient than electric heaters and decrease your utility bills.
Do Oil Filled Radiators Use a Lot of Electricity?
It depends on the settings you are using, but if you compare to other radiator types, the answer is no. Almost 100% of the electricity they are consuming transfers into heat. On top of that, they remain hot for a while even after you unplug them.
Why Do Oil Filled Radiators Smell?
You might notice an odor coming from the heater. This can happen because a tiny portion of heating oil somehow ended up on the surface. Alternatively, the smell comes from paint coating. Either way, the odor should disappear after several hours of using the product.
Oil Filled Space Heater Safety Tips
Unfortunately, heating appliances were the causes of some accidents and fires in the past. That is why you should always remember that safety should be the number one priority in dealing with oil filled heater units. Here is what you should know:
Never Leave It Out of Sight
You need to be in the room and keep your heater insight while it is working. Leaving the house or falling asleep is not an option. Heating appliances are safe by default, but you never know when things can go wrong.
You might think that everything is going to be okay because the heater has a thermostat or you set a timer for it to turn off in an hour. However, you shouldn’t play with safety because if anything goes wrong and you are not there, your house might get burned down.
Heaters Are Not Toys
In other words, keep your kids away from heating appliances. The surface of oil filled radiators becomes cool to the touch when it is working. If a child places its hand on it, they might burn themselves. The same goes for pets, which don’t know that they shouldn’t get too close or they risk an injury.
That is why you should ensure that you place a heater in a safe area and far from children or pets. If you think that you can explain to your children that they shouldn’t go close to the unit, now is the time to do so. Otherwise, make sure that you are around to prevent them from getting too near to the device.
Carefully Choose the Location
You don’t want to risk someone accidentally bumping into the heater while they are walking from one room to another. And you particularly do not want people to trip over the heater’s cord.
That is why you don’t want to place your unit anywhere near the doors, and you should also avoid “high traffic” areas. Instead, find a spot that there is no risk somebody will bump into the heater or trip over the cord.
Avoid Extension Cords
An oil filled heater needs its own power outlet. According to professionals, using an extension cord is not a smart move.
Aside from potential issues with electricity, you increase the possibility of someone tripping over the cable. It might be acceptable to use a 14-gauge thick cord, but it’s still the best option to plug the unit directly into the wall.
