Best Oil Filled Radiator UK Reviews - A Good Home Heating Option

Here I review the best oil filled radiators that are currently available to buy in the UK market. These type of radiators are ideal for heating small to medium sized spaces, small rooms, caravans, shed and garages. They are a lot more cost efficient than electric fan heaters, and can provide a good and valuable source of warmth.

There are certainly plenty to choose from. These are available from many different brands. They can cost anything from £30 and all the way up to around £150. The price varies quite a bit depending on the quality of them, and also the range of features that they have.

I have put together a list of the best that are available in the UK market. Hopefully that will help narrow down your search a little so as you can decide which one is the best type for you.

Who Would Buy An Oil Filled Radiator?

Many people buy these types of radiators. However they all have the single purpose of quickly heating a space. I have seen them used in small sheds, in garages to avoid damp, in smaller offices and in various parts of the home. They are, in my opinion, safer and cheaper to use than other methods such as electrical, gas or blow heaters. They are also very useful to have in case of any power cuts. There are few things worse than freezing inside a house and waiting on power being restored.

In addition to this, these radiators are that they are economical. quiet and are generally considered to be one of the safest forms of heating available.​

So as you can see they have several uses. You can also get a few of them to use in different parts of the home. Personally I use one in my garage to prevent dampness, a similar one in my garden shed, and I also have one in my roof space where I sometimes work from home.

How Do Oil Filled Radiators Actually Work?

Many buyers can easily get confused as they believe these work the same as oil heating. That isn't the case. They work by plugging them into an electrical socket. When you do this, the electric heats up an element at the base of the radiator. This element heats up the oil inside the radiator. By means of convection, this starts the oil flowing through the metal columns, and it is this that generates the heat.

Below I have included a couple of videos that explain how they work.

So as you can see, these are efficient and most importantly a very safe means of heating a small to medium sized space.

How to Pick the Best Oil Filled Radiator for You?

Each person reading this article will want to consider buying one of these for a specific purpose. Below I have pointed out the main features and benefits of these efficient heaters, so as you at least understand the terminology, that manufacturers use.​

Power - ​This is the measurement that you will see and is always measured in watts. The size of this determines how big a space your radiator will be able to heat up efficiently. Many people go for the biggest size such as 2.5 KW, but for a small space a much smaller one will do. For example to keep the damp down in my outdoor shed, I use a 500 watt heater. That is perfect for doing that. Always keep in the back of your mind, the bigger the wattage, the bigger your electric bill will be.

Size, Weight & Portability - ​These three things almost link together. You may only want to use this type of radiator at certain times of the year. When not in use it will need to be stored away. That takes up room and the radiator also needs to be moved around. So the size and weight are important factors to consider. Many of these also come with castors so as they can be moved from one room to another.

These radiators are usually heavy as they are made from metal, and filled with oil. They are not lightweight so check that if you need to regularly move it around, that is had handles and some type of wheels or castors.

Safety First - ​For many this is the number one concern. Never take risks with any type of heating and oil filled radiators are no different. The better brands, and slightly more expensive models will have thermostatic valves fitted. These are used to regulate room temperature. You set the temperature that you want the space to be heated at. When the room reaches that temperature, the radiator cuts off, and only comes back on when that temperature drops.

Again the better brands and models also have an auto-shut off should you forget to switch them off, or accidentally fall asleep.

Some of these heaters also have what is called "cool touch" exteriors. So although they convect good heat through the vents, the outer shell remains cooler to the touch. These are ideal if there are kids or pets in the home.​

The Electric Bill - ​As I mentioned earlier, all forms of heating cost money. Although you will have no oil bill, these do run off your main's electricity supply. Therefore you have two costs; the cost of buying the radiator and the ongoing running costs. The more powerful the radiator the more expensive it is to run. To help understand the costs the average price of electric in the UK is around 10p for 1 kilowatt hour. So let's assume you bought a 2 Kilowatt heater. It would cost around 20 pence to run this for an hour. if you had it on for 3 hours a day, that would cost about 60 pence per day. In a month that would be around £18-20 on your electric bill.

Please note the electricity rate varies a lot throughout the UK. It depends on your supplier and also on peak and off peak tariffs. Check what rate you are paying to work out a more accurate cost.​

Warranty - ​Personally I like a solid warranty on any product that I buy. As you can see from the list above many of these come with a solid enough 2 year warranty. The better brands like Dimplex and De'Longhi offer longer warranties, but you do pay more for them. Just be aware though that many of these guarantees and warranties MUST be activated online. Make sure when you do buy that you don't forget to do this. Many people simply forget and then the warranty is useless.

Style and Appearance - ​This is not top of my list because it mainly comes down to personal choice. Some of these look like chunky radiators whereas some of them look sleek and stylish. Their main purpose is to heat a space, but you will also maybe want to consider something that looks really good.

How Energy Efficient Are Oil Filled Radiators?

For many buyers the question of being cost efficient is one of the most important. Now clearly any type of heating will have a cost. From the simple coal fire, oil or gas heating, the bottom line is that they all cost money. For those considering an oil filled radiator  though, the alternative is typically some other form of electric heater. Usually these are blow style fans. In terms of the electricity bill, the oil filled radiator uses about 25% of the power that an electric heater uses. They are also safer and can usually be set on a timer.

Now to balance all of this out, the oil filled radiators will only heat small to medium sized spaces. So it really comes down to the size of area you are trying to heat. When making your buying decision think only of the size of the area that you are trying to heat. Think also of the room you are trying to heat. For example to use a gas style heater in a confined space such as a bedroom would be dangerous because of the potential fumes and fire risk. An oil filled space heater would be a much better option. ​

These oil filled heaters do come in different sizes and with different levels of power. These can be as low as 200 watts and all the way up to 2,500 watts.​ Remember this when making your choice as you want the most efficient for the size of space you need to heat. The more power your radiator needs, the more electricity it will use.

How Safe Are Oil Filled Heaters?​

For many buyers, and especially for the elderly, a prime concern is the safety of any type of heating. There have been many fires and indeed loss of life as a result of faulty appliances.​ With an oil filled radiator, most experts will agree that this is one of the safest methods of heating available. No fuel or oil is actually burned, the unit is sealed, and the surface temperature is lower.

The better brands and models also come with some built-in safety features. For example in the event of the heater getting knocked over, the unit automatically switches off. One should of course be sensible as with any heater. These are not for drying clothes over, or for placing in areas of high moisture such as a bathroom.​

Summary of Oil Filled Radiators for the Home or Office

I like these as a method of heating a small to medium sized space. As you can see the average price for these is around £40-50 with the better quality brands being a higher price. It all comes down to how much you can afford or are willing to pay. For garages and sheds appearance is not that important, but for caravans or rooms in a home that should be a consideration for you.

The most important thing is to make sure it has all the good safety features and that you buy the right size for the space you are trying to heat. Be aware that the running costs can add up, so but one that has enough power to heat your space. Avoid buying a more powerful one just for the sake of it.​
