How to Choose the Best Oil Filled Radiator Heater
There are several oil filled space heaters on the market. But you can’s just pick anyone and god. There are several factors you need to consider when looking for the best oil filled space heater.
Not all oil filled space heaters are made alike. In this section, we are going to take a look at the major factors that will allow you to determine what the best space heater is for your room. Knowing these factors will allow you to make the best decision both for your home and your wallet. After all, when you purchase the best oil filled space heater, you are actually making an investment.
Here are some key issues that you need to consider when choosing an oiled filled heater:
Size of the space or room
You need to get the right length and width for your room, then multiply it to get the exact square foot area. Knowing the square footage of your space will help you know the kind of heater that you should choose. If you are shopping for a large room, but purchase an oil filled space heater that was designed for a smaller room, then your purchase would not be a sound one.
To find the information of the type of square footage your oil filled space heater covers, you can look at the manufacturer's specifications that will be printed on the heater’s packaging.
Design is important
The way the heater is designed will influence your purchase as well. You will find that highly priced heaters have lots of extra unique features. This can be good if you are looking for something that is ultra-great and worth every penny you have. The look of the heater is pretty important as well. If you are planning to keep your oil filled space heater in one location, then you want to make sure that it matches your room. Luckily, all the options we have listed above are ones that are aesthetically pleasing and work well in any living space.
A majority of the heaters you will come across will come with safety features. The features will range from basic to more sophisticated. For instance, most heaters may come with an overheating or over tip safety features that prevent accidents from happening. Having the right safety features in your heater really depends on who will be around your heater when it is in operation. If you have children or pets, then it is best to shop for an oil filled space heater that is child and pet friendly.
If heat is something that tops in your priority on the heater selection, then you may consider investing in a heater that has taller fins. Tall fins heater have a large surface area and they provide a good amount of heat. These types of oil filled space heaters are also cool to touch so they are great to use around young children. Keep in mind that the more fins you heater has, the more heat it can throw off.
If you will be moving a lot with your heater from one room to another, then consider investing in an oil filled space heater that has caster wheels.
You want to choose something that will last longer for more than 3 years or more. For that reason, look at the material that the oil filled space heater is made up of. Most heaters are designed with steel. This is because steel is a durable and strong material. Steel will not rust like aluminum and other metal. Also, steel is easier to clean and maintain for long term use.
Another thing worth looking at is whether the oil filled space heater has an enamel coating. An enamel coating doesn't flake and it is easy to clean.
Type of oil
Different kinds of heaters have different oil types. The most common types of oil are petroleum, diathermic, and mineral oil.
Diathermic is the most popular type of oil that is found in most heaters. This also means that it is the priciest. Diathermic oil is great because it is safer and provides lower pressure even when the heat is high. When choosing an oil filled space heater, we recommend shopping for one that has diathermic oil.
Size of the heater
Heaters are made with different sizes. The most common ranges of heights are 24 to 26 inches while the width takes on from 6 to 10 inches. Know that bigger sizes don’t mean the heater is will produces more heats.
Oil Heaters Mechanism (How it works)
While many people are able to identify an oil filled space heater, not many can explain how they work. More importantly, many users don’t understand how they are different from any other types of heaters.
The good news is, we have got a detailed explanation that outlines just that. Here is everything you need to know about how a space heater operates.
How it works
Basically, an oil filled space heater features columns of metal fins. This is where oil flows freely on them. A heating element is located at the base of the heater and in the cavity.
When you plug the heater into the power outlet, an electric current passes through the resistor inside the heater. This then turns energy into heat.
The diathermic oil then absorbs the heat inside the heater. The oil is heated at the base of the heater, and then it starts to spread and circulate through the metal fins or column.
Oil moves through the fins onto the cavity that offers a large surface area for the heat to radiate over. Oil heating in this area has high heating capacity and boiling point. In fact, the highest temperature ranges from 150 to 300 degrees Celsius.
These features make this oil act as a reservoir while at the same time provide a large amount of heat and fluids that stay in liquid form ready to be transferred the next time it if needed.
These heat then circulates through your room using natural convection of air. While that is a simplified version of how an oil filled space heater works, it is a rather different method than how other heaters like ceramic and electrical ones work.
How much oil is needed?
Many people still believe that an oil filled space heater uses oil and that oil is replaced regularly. This is not true. This is because the oil is not consumed as fuel. Rather, its purpose is to act as a heating reservoir.
The volume of oil remains the same as long as the heater is in perfect condition year after year. Also, the oil will keep flowing through the same metal column when you need to use the heater.
Electricity will still be used to warm the heating element at the base of the oil filled-heater. The heat will then be transferred to the oil, which will then spread across the metal fins.
For those of you buying oil-filled heaters, the more fins you have the larger the surface area that allows more air to come in constant with the heater.
So in summary, once you understand the method by with an oil filled space heater works, you will understand that you do not need to replace the oil.
Oil Filled Space Heater Safety Concerns
There are some concerns that you need to keep in mind when using an oil filled space heater. Because it is a heater, to begin with, an oil filled space heaters is not a toy. Instead, when compared to other types of heaters, an oil filled space heater can actually be harmful.
For instance, electric heaters are said to have a cool to touch surfaces that makes it a safe device for those people that have kids and pets. But, when it comes to oil-filled heaters, the metal fins alone are super-hot and sometimes that heat warms the floor surface.
If you have a toddler that is learning how to walk, you will need to monitor him so that he does not touch or come in contact with your oil filled space heater. Because of that, here are some additional safety features that you need to know.
Never Use It With An Extension Lead
Most oil filled heater that you will buy will have a short cord and you may be tempted to have an extension lead. As a general rule of thumb, it is advised that you not to do so. Instead, aim to place your unit in a location where an outlet is acceptable. If you do need to use an extension lead, it is best that you seek advice from a professional electrician beforehand
An electrician will typically advise you to use a 14-gauge thick extension cord.
A safety label shows a sign that it is a safe heater to be used at home. And when buying this heater, always buy from reputable sources.
Never Repair Or Try To Open Your Heater Even If You Know What is Going On
We like to have control over what we can do with things. Well, an oil-filled heater is not a DIY tool that you can open; it is a heater that will need a professional to open. Becaue of the oil inside, it is a hazardous piece of equipment in nature.
Keep It Away From Obstruction
Oil filled heater ignites gives off too much heat and it is tempting to use it to dry your clothes. Never use it to dry wet clothes or hang a wet towel on it. When the heater is working nothing should obstruct it. If there is obstruction, this could lead to an accident such as a house fire.
Switch Off When Not In Use
Never leave the heater unattended, always switch it off when not in use. Also, it should be placed away from high traffic areas. You need to keep the heater away from high traffic areas to prevent any accidental trips or the potential of it being knocked over.
Never Tamper With The Thermostat
The thermostat is not something that you can alter unless you want to risk your life, doing that would lead to overheating.
Most heaters will come with safety features such as the overheat features. This feature is straightforward in the fact that it prevents overheating. There is also an anti tip feature that lets the heater shut off automatically when someone knocks it over.
When you choose a heater with such features, you can lower the potential risk of injury by 90%. Because of this, many manufacturers have been only adding to the safety features in their design.
The Fins Need To Be Clear
The fins get hot over time when the oil filled space heater begins to work. Because of this, be sure to avoid inserting things on them. Leaving objects on the fins will not only block the heat but lower the radiator's efficient. In both ways, this can be dangerous.
Advantages Of Oil Space Heater
Oil filled space heaters are considered the best heaters for some reasons. While this might be debatable for some, one this is not. Oil heaters can't be compared to electric heaters or fireplace for that matter.
If you are thinking of owning a heater, here is why oil filled heaters will be the best option for you.
Lots Of Heat For Constant Warmth
Visit any online forum and you will likely find few people complaining about the heat output. Oil heaters deliver lots of heat, unlike electric fireplaces that let you enjoy primarily the ambiance and amazement of flickering flames all while producing less heat. If heat is what matters to you the most, then oil-filled heaters are your best options.
Saves Your Energy Bills
With oil-filled heaters, there is no such thing as zonal or central heating that pile up your energy bills every month. Oil-filled heaters are made to warm up your room efficiently and make sure that the heat is enough for you and your family. For that reason, oil-filled heaters are energy savers. In fact, all our oil filled space heaters provide a great amount of energy efficiency.
Their construction includes caster wheels for easy movement from one room to another. This ability to move them solves the problem of buying an oil filled space heater for every room. Some oil filled space heaters also have carrying handles that let you drag the heater easily without causing lots of stress on your back or spine.
Silent In Operation
Read any review about other types of heaters such the electric heaters, electric fireplace and you won't miss a common complaint among customers.
Noise level is something that every customer that buys other kinds of heaters have to live with. Luckily, an oil-filled heater doesn't use a fan, so there is no noise.
In fact, the major reason why most people are shifting to an oil filled space heater is because there is zero noise.
Other types of heaters such as electric heaters dry the air in the room. And after some time you start suffering from dry throats or sinuses.
In fact, it is advisable that you should opt for other options of heaters if you have respiratory problems. Oil filled heaters don't have any health risks, they are friendly. So if you already suffer from respiratory issues, then an oil filled space heater would be your best bet to go with anyway.
Compared to a gas fireplace, electric fireplace, and other types of heaters, oil-filled heaters are the safest of all heaters. This is because their heating element is safely sealed. There is no way it can be tampered with.
In addition to that, manufacturers equip this unit with lots of safety features like overheat; tip over and anti-freeze features ensure that you will be safe when using them.
Easy To Clean And Maintain
When you look at radiant heaters, they are expensive to maintain. They really eat up the energy cost.
The oil-filled heaters don't need to be refilled. This is different when compared to a gas heater that uses propane and methane. All you need is to plug in your oil filled space heater and you are ready to go.
Other Heaters Vs Oil Filled Heaters
So should you shop for an oil filled space heater or another type of heater? This is one of the questions that constantly come up in every forum. While all heaters stack up differently, here are some final factors that you should consider.
The power consumption of an oil filled space heater and its competition both measure up to about the same. For example, to heat a 150 square foot room, they will both consume 1500 watts. Making a choice between an oil filled space heater and the competition based on wattage will be difficult because they are both winners.
There is a clear disparity hear. You will often find that an oil filled space heater will often be priced higher than all other types of heaters. This is because they have more advanced unique features. The low-end price for an oil-filled heater starts at $50 while an infrared heaters starts at $30.
There is a big difference in this department as well. While both types of heaters produce lots of heat, an oil filled space heater heat output can't be compared to what the other heaters throw.
Even if you bought a random oil-heater that you picked out of the blue, you won't be disappointed with the heat output. Other features on the heater may not impress you, but the heat is something that you will have no say about.
Both infrared heaters and oil-filled heaters are made differently. For instance, an infrared heater warms the object it hits, not the air. For that reason, it produces immediate heat. There is no need to wait for it to heat up.
On the other hand, an oil-filled heater will start to warm the air first, then the warm air will rise while the cold air lower down. The circle continues until the whole air in the room is warm.
For this process to take place you have to wait. But once the oil filled heater reaches the desired temperature it is capable of maintaining the same heat level for a longer period of time than the infrared heaters.
