Our Guide For Buying The Best Oil-Filled Radiators

The Benefits of Having an Oil-Filled Radiator

There are several benefits that you will get for having an oil-filled radiator as opposed to other heating methods in your home. First, oil-filled radiators are relatively silent compared to many heaters because they do not use a fan to push hot air out. Secondly, oil-filled radiators heat up the air in your room while retaining its humidity, thus making it pleasant to breathe. It is also no doubt that oil-filled radiators are more energy efficient than other heating appliances. This is because all of the electricity is used to heat the oil without wasting any power.

The heat retention property of oil makes oil-filled radiators the best option to heat a room. Unlike a fan-assisted one, an oil-filled radiator does not cool off as soon as you turn it off. You are also in a better position to control the temperature of the room with the help of an automatic thermostat. Oil-filled radiators are quite portable as most of them come with castors and integrated handles. 

Also, most of them are small enough to be picked up and carried from one room to another. When it comes to safety, oil-filled radiators are better than other heaters available on the market. For instance, you can hardly reach the heating element, which is the oil inside the radiator.

Oil-filled radiators have safety features that help you operate them without any risks. They come with an overheat protection feature which means that the heater will switch off immediately in the unlikely event that it gets overheated. If you are wondering which electric radiators are best, you should be informed that oil-filled radiators are much better than the rest in almost all aspects.

Safety Precautions

Every year, we hear of accidents associated with oil-filled radiators. We all know how dangerous hot oil can be. However, by simply following the manufacturer’s instructions and a couple of standard operation procedures, you stand a pretty good chance of avoiding all the potential accidents that can happen. The first safety precaution is that you should never use extension cords that cannot handle the load of your radiator. It is recommended to plug your oil-filled radiator directly into the wall socket. This will go a long way in preventing any accidents that come as a result of overloading the extension.

It is advisable for you to rely on the internal components of the oil-filled radiator. Adding an external component such as temperature control equipment may tamper with the radiator and result in overheating or even cause damage to the appliance altogether. Also, if your oil-filled radiator came with wheels, you should ensure that they are secured in place before letting children near them. You should also ensure that you keep a close eye on children when they are playing around the oil-filled radiator. To be on the safe side, don’t allow children or pets around the heater when it is running.

Factors to Consider When Buying an Oil-Filled Radiator

When shopping for an oil-filled radiator, there are certain things that you cannot ignore if you want to get the best convector heater on the market. The first important consideration is the power rating. This is basically a measure of its ability to transfer heat to the room and it is measured in watts. The higher the wattage, the more powerful the oil-filled radiator, which means it has a high heating ability. The size of your room should give you an idea of the wattage that is suitable for your heating needs. To work out the wattage you require, you simply need to multiply the area of your room in square meters by 100. The result should be the power rating of the oil-filled radiator that is suitable for your heating needs.

The other consideration that is equally important in the selection of an oil-filled radiator is the size in terms of its dimensions. The length, width, and height of the radiator are important considerations because you need to get one that will fit into the space that you have. A large oil-filled radiator is good to have but it requires a lot of space. If you have a small space, it is always a good idea to go for a small-sized radiator. 

Also, look for other features such as an integral ergonomic handle and the wheels. Also, depending on the size of your space, you should consider whether the radiator is a mounted type or one that rests on a stand. Modern housing designs are embracing the wall-mounted types of oil filled radiators. Although this design limits the portability of the radiator, it helps to save on space.

The presence of a timer is another major consideration that you need to take into account when shopping for an oil-filled radiator. This feature enables the radiator to automatically turn itself on or off when necessary. It is a great convenience to have a timer in your oil-filled radiator because it means you don’t have to manually turn it on or off every time you want to. The price of the electric oil-filled radiator is another major consideration. This is because it is a deciding factor in any purchasing decision. When considering the price, do not just look at the price tag of the radiator. You also need to consider how much it’s going to help you save once it’s up and running. The worst thing would be to purchase a cheap oil-filled radiator that is not energy efficient.
