Why Consider an Oil Filled Radiator?

These radiators are great to heat sold rooms and offices. They are generally very compact and lightweight, making them extremely portable allowing you to place them wherever extra heat is needed.

Oil filled radiators have a few advantages over other electric heaters. These advantages make them both safer, and more efficient than other heaters. One of the most common problem with other electric heaters is that many people don’t feel safe using them during night. And electric heaters generally are costly as they will use a fair amount of electricity, and some cheaper models can have faults leading to short circuiting. In the worst case this could lead to damaged wiring and in some cases electrical fires.

If you are worried about electrical heaters and safety then oil filled radiators are the answer. Unlike other electrical heaters, oil filled radiators tend not have such a high risk of causing electrical damage. Like other electrical heaters they must be plugged into a power socket however the amount power the use is only about 25% of the typical power consumption of other electric heaters. The reason for this is based on how the radiator works. The heat conserving oil in the radiator is slowly heated to a specific temperature, and then the heating unit shuts off.

How to find an Oil Filled Radiator to meet your needs?

Here are the key points you may need to consider when selecting your ideal oil filled heater:

  • Power
  • Safety features
  • Appearance
  • Weight
  • Portability
  • Cost

The power you will require from a radiator will be determined by its expected use. For instance the larger the area you want to be heated the greater power the radiator must be capable off.

Safety Features

Since oil filled radiators are generating heat there is always the minuscule risk of something going wrong resulting in injury. Some units have built in safety features that can include auto-shut down, anti-frost and so on.


I like most people tend to part with my money when I love the appearance of a product even if it does not fulfill all my requirements. I think to myself, do I find the product appealing? If not then I will not touch it with a barge pole. This also applies to oil filled radiator since there are all manner of shapes and sizes that will meet most peoples expectations.


Look into the weight of the unit, generally the lighter the radiator the more portable


One of the most important features to look out for in an oil filled radiator is how easy is to move around? How portable is the unit? Check the dimensions of the unit to ensure it will easily fit wherever you choose to sit the radiator. There are various sizes of oil filled radiators so always pick the one that fits your needs and requirements and more importantly fits in your room.


If money is no were no object then you could forget about this consideration but for many the cost of the unit is probably the most important consideration. Generally you can easily pick up a decent model from between £50 to £100. The more you are willing to spend the more features you will likely get including extra safety features.


Many products come with a manufacturer’s warranty that should give a customer peace of mind, so you are ensured of getting a replacement for a faulty unit if the fault appears within the warranty period. Manufacturers offer different length and coverage of warranty. There are some that can offer a lifetime limited warranty while others offer one or two years of limited warranty. In terms of coverage, there could be some differences too. Therefore, you need to make sure that you have read and understood the warranty coverage first before buying a specific product.

How do Oil Filled Radiators Work?

So how do these radiators work, firstly the heat conserving oil is heated by heating elements within the radiator to the desired temperature. The oil circulates throughout the coils and fins of the radiator to heat them. These fins in turn will heat the air that moves over them and then will cool the oil as they cool. This cycle will eventually cool the oil to a point where the radiator turns back on. This is much safer than an electric heater that must stay on constantly. Since there are no moving parts to take care of maintenance is rarely required.

Newer radiators have a number of safety features such as overheating shutoff sensors and anti-tipping detectors have made the units extremely safe to use. And they can heat rooms quickly due to the large surface area of the radiator fins.
