What Are Oil Filled Electric Radiators

Oil filled electric radiators work by using oil-filled cavities to store and dissipate the heat generated by the radiator’s coils. This efficient system allows oil filled radiators to provide a steady and comfortable warmth over a long period of time. In addition, oil filled radiators are relatively slimline and can be easily moved around the home for optimal positioning. As oil does not need to be changed regularly like other heating systems, oil filled radiators also require minimal maintenance. Overall, oil filled radiators provide an attractive option for both homeowners and commercial properties looking for a reliable and cost-effective electric heating solution. More on what are oil filled radiators here.

How to Select The Best Oil Filled Radiator For Your UK Home

The most important aspect when selecting the best UK oil filled radiator is how much heat it produces. It is not uncommon for people to buy underpowered oil filled radiators, and then blame the heater for not being very good and expensive to run. If you have a 20 square meter room and buy a 1,000 watt oil filled radiator, this will not be adequate to heat the room.

Below is a rough guide on the best electric heater size of heater for room size, this is based on an average terraced house with average insulation.

Do Oil Filled Radiators Use a Lot of Electricity in The UK?

Yes, oil radiator heaters can use a lot of electricity in the UK depending on how often they are used. The amount of electricity required to heat an area depends on the size of the room and its insulation. A standard sized UK room with good insulation might require around 1–2 kilowatts per hour, while a larger or poorly insulated UK home may need 3–5 kilowatts per hour.

Oil radiator heaters can be efficient and cheap when used correctly. Depending on the wattage of the heater, it may use a lot or very little electricity. It’s important to pay attention to the wattage rating and adjust it according to your needs. If a heater is too powerful for the area it is heating, it will consume more energy than necessary, the right sized oil filled radiator will be cheaper to run.

How Long Do Oil Filled Radiators Take to Heat Up

The average 2000 watt Oil filled radiators can get warm in 10 minutes but will usually take around 30 minutes to heat a room. Although they can take longer to heat a room when compared with fan heaters, or convector heaters, once switched off, they can continue to prove heat for around 20–30 minutes as the oil takes a while to cool down. 

Why Use an Oil Filled Radiator

Oil filled radiators are a great choice when it comes to heating up any space. They provide a steady and consistent heat output, making them ideal for long-term use. Their oil reservoirs also help to dampen the sound of the radiator, creating a quieter environment.

The oil in the reservoir helps to keep dust and dirt from collecting inside, making them less susceptible to dust build-up over time. Additionally, oil filled radiators can be energy efficient when the thermostat is used, this can save you money on your heating bills compared to other forms of electric heating.

Because oil filled radiators don’t produce any open flames or hot surfaces, they are much safer than other types of heaters and won’t be as hazardous if accidentally knocked over. All these factors combine to make oil filled radiators an ideal choice for heating up any space.

Advantages of Portable Oil Filled Electric Radiators

Portable Oil filled electric radiators are an efficient, cost-effective and environmentally friendly heating solution that offers numerous advantages compared to other heating systems. These radiators provide a consistent level of warmth with no fluctuation in temperature levels.

The oil within the radiator requires very little to no maintenance, as it is sealed away from external elements and does not need topping up like portable gas heaters.

In addition, portable oil filled radiators do not require ventilation and create less noise than other types of heating systems such as fan heaters.

Furthermore, since the oil inside the radiator absorbs heat over time, the radiator becomes more energy efficient as it warms up the space for longer periods at a much lower cost with a thermostat, this helps to reduce your carbon footprint and bills! Additionally, oil filled electric radiators are easy to use, making them a great choice for those looking for hassle-free heating solutions.

With all these advantages, it is no wonder why portable oil filled electric radiators are becoming increasingly popular. Whether you just require additional warmth or require a complete heating solution, a portable oil filled electric radiator could be the perfect choice for your home, office or any other space that requires heating.

Can You Leave an Oil Filled Radiator on All The Time?

Generally speaking, it is not recommended to leave an oil filled radiator on all the time. Doing so could potentially increase your energy costs and may be dangerous if the heat is not managed properly. Therefore, it is best to turn off the oil-filled radiator when it is not needed or adjust the temperature accordingly.

Do UK Oil Filled Radiators Run Out of Oil?

No, UK oil filled radiators do not run out of oil. The oil is sealed in the radiator and the heat produced by the element is used to heat up the oil, which in turn acts as a heat reservoir to warm surrounding air. As long as there is no external damage to the radiator, it will never require refilling with oil.

Are UK Oil Filled Heaters Better Than UK Central Heating?

UK Central heating is usually considered to be the more cost-effective cheap, and efficient option for heating your whole house. Since it works by circulating hot water through a series of pipes and radiators, it can heat up a large area quickly. Furthermore, it can also be programmed in order to set temperatures at different times of the day, making it more energy efficient.

On the other hand, UK oil filled radiators are better suited for heating one single room or space. This is because they take longer to warm up than central heating systems, but produce a consistent level of heat over a longer period of time. Therefore, if only one room needs to be heated, oil-filled radiators are often cheaper and more practical than central heating as they require less energy overall
