Choosing Between Oil-Filled and Panel Electric Radiator Heaters: Which Is Best?

Oil-filled radiators provide a more steady heat and are better suited for larger rooms, while panel electric heaters are more affordable and effective in smaller spaces. Choosing the right type of heater for your home or office can be a daunting task.

With so many options available, it can be difficult to determine which one will provide the most efficient and effective heating for your space. Two popular options are oil-filled and panel electric radiators. While both types of heaters have their benefits, one may be better suited for your particular situation.

Let’s take a closer look at the differences between oil-filled and panel electric heaters to help you make an informed decision.

Choosing Between Oil-Filled and Panel Electric Radiator Heaters: Which Is Best?


Understanding Oil-Filled Radiator Heaters

If you are in the market for a new radiator heater, it is essential to know the difference between the two main types: oil-filled and panel electric. While panel heaters are efficient and cost-effective, oil-filled heaters offer a more comfortable, consistent warmth.

What Are Oil-Filled Radiator Heaters?

Oil-filled radiator heaters feature a metal frame that is filled with oil, heating the room using convection currents. The warm oil heats the metal and air around it, causing it to rise and circulate the warm air throughout the room.

How Do They Work?

Oil-filled radiator heaters work by heating up the oil inside them using electricity. As the oil heats up, it expands and rises to the top of the unit, creating a convection current that heats the air around it. The heat is then released, keeping the room comfortable and warm.

Benefits Of Using An Oil-Filled Radiator Heater

There are several benefits to using an oil-filled radiator heater, including:

  • Energy efficient: Oil-filled radiators use less electricity than panel heaters, making them more energy-efficient, and cost-effective.
  • Quiet operation: They operate with virtually no noise, unlike panel heaters, which can emit a low hum.
  • Safe to use: These heaters do not have exposed heating elements, making them safer to operate around small children or pets.
  • Portable: Most oil-filled heaters come with wheels, making them easy to move around from room to room as needed.

Drawbacks Of Using An Oil-Filled Radiator Heater

While oil-filled radiator heaters have their advantages, they also have some drawbacks to consider:

  • Slow to heat up: It may take longer for an oil-filled radiator to heat a room as compared to panel heaters.
  • Bulky: They appear bulky due to the metal frame and oil cavity, making them hard to store
  • Heavy: The oil inside these heaters makes them heavy and challenging to move around, especially when going from one level of the house to another.

Oil-filled radiator heaters offer an efficient, safe, and energy-saving option for heating your home. They may be bulkier, but the benefits outweigh the cons, ensuring you have a cozy and warm room throughout the winter season.

Understanding Panel Electric Radiator Heaters

Choosing the right electric radiator heater is essential to ensure your home stays warm and cozy during the chilly months. Panel electric radiator heaters are an excellent option as they are energy efficient and easy to install. In this section, we will look at the working, pros, and cons of panel electric radiator heaters to help you make an informed purchase decision.

What Are Panel Electric Radiator Heaters?

Panel electric radiators are a type of heating appliance that work by generating heat through an element inside the appliance, which then radiates heat throughout a room. Panel electric radiators can be freestanding or wall-mounted, and they come in different sizes, colors, and shapes to match your interior décor.

How Do They Work?

Panel electric radiators work using an electrical heating element that is embedded within the system. This element heats the air inside the appliance and then disperses it throughout your room, keeping you and your home warm and cozy. Most panel electric radiators use conduction, convection, and radiation to distribute heat to the surrounding areas.

Benefits Of Using A Panel Electric Radiator Heater

There are several advantages of using a panel electric radiator heater, such as:

  • Energy-efficient: Panel electric radiators are energy efficient as they use a thermostat to keep your room at a constant temperature. They do not require a central heating system, which means you can turn them on and off when you need them. This feature makes them a cost-effective option for homes.
  • Versatility: Panel electric radiators can be wall-mounted or freestanding, making them versatile and easy to install. They come in different colors, shapes, and sizes to match your interior décor.
  • Silent: Panel electric radiators do not produce any noise, making them perfect for bedrooms and quiet spaces where noise can be disturbing.
  • Safe: Panel electric radiators are safe to use as they do not produce any flames or fumes. Additionally, they have safety features such as overheat protection and automatic shut-off that prevent accidents.

Drawbacks Of Using A Panel Electric Radiator Heater

Despite the advantages, panel electric radiators also have some cons, such as:

  • Slow heating: Panel electric radiators heat up slowly, which means they are not suitable for quick heating. They require more time to distribute heat as compared to oil-filled radiators.
  • Temperature control: While they are equipped with a thermostat, panel electric radiators do not heat up quickly, which can cause temperature fluctuations.
  • Energy consumption: Panel electric radiators consume a considerable amount of energy, which is a concern for people who are conscious of their carbon footprint.

Panel electric radiators are an excellent option for people who are looking for an energy-efficient, safe, and easy-to-install heating solution. With its advantages and disadvantages, you can make an informed purchase decision when choosing between oil-filled and panel electric radiators.

Which Type Of Radiator Heater Is Best For You?

Choosing Between Oil-Filled And Panel Electric Radiator Heaters: Which Is Best?

Radiators heaters make your room warm, cozy, and comfortable during winters. They come in different types and sizes. Two of them are oil-filled and panel electric radiator heaters. Both have their own benefits and features. So the question is:

To help you make an informed decision, consider the following factors:

Factors To Consider When Choosing Between Oil-Filled And Panel Electric Radiator Heaters

  • Heating capacity: Oil-filled heaters take a longer time to heat up, but they have a higher heat retention capacity. In contrast, panel heaters heat up faster but do not retain the heat for long.
  • Energy efficiency: Look for a heater with high star ratings and energy efficiency ratio (eer) for lower energy bills.
  • Price and warranty: Panel heaters are cheaper than the oil-filled ones, but they have a shorter lifespan. Consider the cost and warranty offered before making a purchase.
  • Portability: If you need to move the heater from one place to another, consider a lightweight and portable panel heater.

Keep these factors in mind when choosing a radiator heater. Let’s compare oil-filled and panel electric radiator heaters based on these factors:
