How to Choose the Oil Filled Radiator Heater

They are different heaters on the market, and you have to know what you want.

What characteristics do you need in an oiled filled heater, because heaters are not designed the same.

This is a section, where as an energy conserving smart shopper you may need to have a pen and a pencil for you to write down what you really want.

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.

This will help you know the kind of heater that you should choose. On the market, most heaters have different square foot area.

Information like this you can find on the manufacturer's specification on the heaters. You need the right size of the heater that can provide enough warmth in your room.

Design is important

The way the heater is designed will influence in your purchase.

You will find that highly priced heaters have lots of extra unique features, which can be good if you are looking for something that is ultra-great and worthy every penny you have.

Some of the things that you will find in a heater are:

Safety features

Majority of the heater will come with safety features. It depends on what you want.

For instance, most heaters may come with an overheating or over tip safety features that prevents accident from happening.

Taller fins

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 large surface area that provides good amount of heat and are cool to touch.

Remember that the more fins, you heater has, the more heat it can throw off.

Caster wheels

If you will be moving a lot with your heater from one room to another, then consider investing in a hater that has caster wheels.

Premium construction

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 heat is made up of. Most heaters are designed with steel.

Steel is durable and strong. Steel does rust like aluminum and other metal. Steel is also easier to clean and maintain for long term use.

Another thing worthy looking at is whether the heater has enamel coating which 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, because it is safer and provides low pressure even when the heat is high.

If you are choosing a heater, I would recommend a heater 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)

A lot of debates are going on forums on how this heater works. And how it is different from any other types of heaters? I visited one forum and provided a length-detailed explanation until recently one of my subscribers asked the same question. And I decided to create a short post that answers that same question.

Oiled filled heaters have metal fins column, where oil flows freely on them. A heating element is located at the base of the heater and the cavity.

How it works?

When you plug the heater on the electricity, electric current passes through the resistor inside the heater, which 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 this fins onto the cavity that offer large surface area for the heat to radiate. Oil heating at this area has high heating capacity and boiling point. In fact, the highest temperature ranges between 150 to 300 degrees Celsius that makes this oil have a high boiling point.

These features makes this oil act as a reservoir while at the same time provide large amount of heat and fluids that stay in liquid form ready to be transferred the next time it is needed.

These heats circulate through your room using natural convection of air. Where warm air rises up to replace the cold air. I now hope that you have understood the science behind how oil-filled radiators work.

How much oil is needed?

It remains a misconception up to today, because most people still believe that an oil-filled heater uses oil and it is replaced regularly.

This is not true. This because, the oil is not consumed as fuel, 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. 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 the spread across the metal fins.

For those of you buying oil-filled heaters, the more fins you have the large the surface area that allow more air to come in constant with the heater.

Oil filled space heater Safety concerns

I have to admit one thing.

That most oil-filled heaters are not toys. They are potential dangerous compared to other types of heaters.

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 may not touch or come in contact with the oil-filled heaters.

Because of that, here are some few 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.

I will advise you not to do so. If you have to get one at least get advice from a professional electrician before keeping one in your home.

If you are going to buy the cord at least choose the one that is super thick, a 14-gauge thick extension cord would do the trick in most cases.

Safety certification

Most electric wall heaters and electric fireplace have safety stickers on them. When choosing an oil-filled heater look for the label of certification it has before installing one.

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 even if you know what 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, because of its hazardous 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 in it. When the heater is working nothing should obstruct it, because it can be dangerous.

Switch Off when not in use

Never leave the heater unattended, always switch off when not in use.

It should be place away from high traffic areas. You need to keep the heater away from high traffic areas to prevent most people from knocking it 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.

Safety features

Most heaters will come with safety features such as the overheat features that prevents the heater from overheating.

There is over tip feature that lets the heater shut off automatically when someone knocks it over.

Choose a heater with such features that lowers the potential risk of injury by 90%. Some manufacturers even include more safety features in their design.

The fins need to be clear

The fins get hot over time when the oil-filled heater begins to work, avoids inserting things on them. Leaving objects on the fins will not only block the heat but lower the radiator's efficient. In both ways it can be dangerous.

Advantages of Oil space heater

Oil heaters are considered the best heaters for some reasons. Oil heaters can't be compared to electric heaters or fireplace for that matter.

If you are thinking of owning a heaters, here is why oil filled heaters will be the best option for you.

Lots of heat for constant warmth

Visit any online forum, you will never find anyone complaining about the heat output.

Oil heaters delivers lots of heat unlike electric fireplace that lets enjoy the ambience and amazement of flickering flames 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 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.

Portable

Their construction includes caster wheels for easy movement from one room to another. That’s solves the problem of buying every room its own heaters.

Oil-filled heaters also have a carrying handles that lets you drag the heater easily without causing lots of trouble 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 complain among customers.

Noise level is something that every customer that buys other kind of heaters has to live with. An oil-filled heater doesn't use the fan, so there is no noise.

In fact, the major reason why most people are shifting to oil heater is because there is zero noise.

Health friendly

Other types of heaters such as electric heaters dry the air in the room. And after sometimes you start feeling like 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.

Safe

Compared to gas fireplace, electric fireplace and other types of heater, oil-filled heaters are the safest of all heaters.

Closely followed by infrared heaters. This is because their heating element is sealed far away. 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 or infrared heaters, they are expensive to maintain. They really eat up the energy cost.

The oil-filled heaters doesn't need refill that is because its fuel is not consumed but act as reservoir.

This different compared to when you have gas heater like propane and methane. All you need is to plug it into the plug and let it work.

Infrared heaters vs Oil filled heaters

The question is...should shop for an oil-filled heater or infrared heaters? This is one of the questions that constantly come up in every forum.

However, I have to admit that they are both the best heaters. So here is how I measure the two up.

Watts is watts

On the power consumption department both measure up well. I can’t compare them on the basis of which heater consumes more fuel or which eats lots of energy bills? To heat a 150 square foot room, they will both consume 1500 watts.

Price consideration

We have a disparity here.

Oil-filled heaters are more expensive than infrared heaters.

That 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 that is by the end of 2012. If you are looking for something cheaper for, then an infrared heater comes first.

Heat output

There is a big difference.

I have to agree that both produce lots of heat. However, what an oil-filled heater ignites can't be compared to what an infrared heater throws.

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.

Immediate heat

Both infrared heaters and oil-filled heaters are made differently.

For instance, an infrared heater warms the object not the air. For that reason, it produces immediate heat. There is no waiting for you.

On the other hand, an oil-filled heater will start to warm the air first, then warm air will raise and 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. There are more reasons why an oil-filled heater will be better for you.

Verdict

You have read the best oil filled heater. You now know what you should be looking for in a heater.

I made this review 3000+ word plus so that I can help you make an informed decision on which kind of heater you should choose.

But, the most important thing when choosing is a heater is not the warmth that it provides but the safety precaution that you take to keeping everybody safe.
