Unveiling the Shocking Truth: Electricity Usage of Oil Filled Heaters

Oil filled heaters use a significant amount of electricity. They are an efficient way to heat a room, but may be expensive to operate for extended periods of time.

Oil filled heaters are a popular choice for supplemental heating or as a primary heat source in small spaces. They are electric heaters that use oil as a heat reservoir and operate on electricity to circulate the warm air. While they may be more expensive to purchase than other types of heaters, they are known for their energy efficiency and ability to provide consistent heat.

However, it is important to note that oil filled heaters use a considerable amount of electricity and may not be the most cost-effective option for prolonged use. In this article, we will discuss how much electricity oil filled heaters use and whether they are a suitable choice for your heating needs.

Understanding The Basics Of Oil Filled Heaters

Oil filled heaters are popular for their ease of use and efficiency in warming rooms. They work by heating the oil inside the heater, which then radiates heat to the surrounding area. Here are some key points to know about oil filled heaters:

  • They are electric heaters, meaning they use electricity to heat up the oil and produce heat.
  • They are designed to be portable and can be moved from room to room.
  • Oil filled heaters are relatively quiet and do not produce any smoke or fumes.
  • The oil inside the heater does not need to be refilled or replaced, making them low maintenance.

Types Of Oil Filled Heaters In The Market

There are different types of oil filled heaters available in the market. Each one has its unique features and benefits. Here are some of the most popular types:

  • Standard oil filled radiators: These are the most common types, have a simple design and come in various sizes from small to large.
  • Portable oil filled heaters: These are compact and lightweight, making them easy to move around. They are ideal for small rooms or personal spaces.
  • Oil filled convection heaters: These distribute heat evenly and work best in well-insulated rooms.
  • Oil filled space heaters: These are designed to heat large rooms and are equipped with multiple heating settings to adjust the temperature level.

Benefits And Drawbacks Of Oil Filled Heaters

Like any other heating appliances, oil filled heaters come with their own set of advantages and disadvantages. Here are some of the benefits and drawbacks of using oil filled heaters:


  • They are energy efficient and use less electricity than other types of electric heaters.
  • They are safe to use and do not pose a high fire risk since there are no exposed heating elements.
  • They are quiet and produce no sound that could disturb your work or sleep.
  • They are low maintenance and long-lasting.


  • They take a while to warm up a room and are not ideal for quick heating solutions.
  • They can be quite heavy, making them difficult to move around.
  • They are not suitable for use in humid environments as the oil can corrode and rust.
  • They are relatively expensive compared to other types of heaters.

Overall, oil filled heaters are a great option for those looking for a low-maintenance, safe, and efficient way to heat their homes or offices. With a wide range of options available in the market, it is easy to find one that suits your heating needs and budget.

Electricity Consumption Of Oil Filled Heaters

The Energy Efficiency Of Oil Filled Heaters

Oil filled heaters are known for their energy efficiency, as they are designed to heat a room for a longer duration even after they are turned off. Here are some key points to understand their energy efficiency:

  • They use electricity to heat the oil, which then retains and releases heat for a long time, reducing the need for constant power consumption.
  • Their energy efficiency is measured by their wattage – a higher wattage means they will consume more energy.
  • They have a thermostat that helps control the temperature, ensuring that the heat is limited to a specific space, avoiding any wastage.

Calculating The Electricity Cost Of Oil Filled Heaters

Calculating the electricity cost of oil filled heaters is essential to understand its impact on your energy bills. Here are some key points:

  • Use the formula: Electricity cost = wattage x hours used x electricity rate/kwh
  • Suppose the electricity rate in your area is $0.12/kwh. Your 1500-watt oil filled heater used for 8 hours daily would cost you $1.44/day, and nearly $43.2 a month.
  • Keep track of your heater’s usage to know your actual expenditure.

Comparing The Electricity Cost Of Oil Filled Heaters With Other Heater Types

Oil filled heaters are not the only electric heaters available in the market. Here are some comparisons you should be aware of their electricity cost:

  • Ceramic heaters are energy efficient too and have lower wattage than oil filled heaters. They consume less energy and have a lower cost.
  • Infrared heaters are another good option for large spaces. They warm a room by emitting radiation, but their electricity cost is higher than oil filled heaters.
  • Baseboard heaters are also energy efficient but may cost more than oil filled heaters.

Tips To Reduce Electricity Consumption And Save On Energy Bills

It’s essential to know how to use your oil filled heater efficiently to get the most out of it. Here are some tips to help you save on energy bills:

  • Close all the doors and windows to avoid any heat loss and let the room heat up quicker.
  • Lower the thermostat temperature by a degree or two to consume less energy.
  • Unplug the heater or turn off the power switch when not in use to avoid any energy wastage.
  • Place the heater in a centralized location, avoiding any obstruction and allowing the heat to flow evenly.
  • Get your heating system inspected by a professional so that it functions efficiently.

Oil filled heaters are energy-efficient and provide heat effectively to warm up a room. Understanding the electricity cost and comparing it with other heater types help make an informed decision. Using heaters appropriately and incorporating energy-saving tips can help reduce power consumption and save on energy bills.


After careful consideration of the electricity usage of oil-filled heaters, it’s obvious that these appliances can cost a pretty penny to run. However, with proper usage and maintenance, oil-filled heaters can be a cost-effective alternative to other heating options. It’s essential to keep in mind that the size of your space, the insulation of your home, and how long you run your appliance can affect energy consumption.

When it comes to choosing the right oil-filled heater, it’s essential to consider its energy efficiency ratings and features such as timers, thermostats, and wattage. Be sure to unplug your heater when not in use and keep it away from combustible materials or fabrics.

Ultimately, oil-filled heaters can provide a comfortable and cozy living space without breaking the bank on electricity.
