Is Oil Filled Heater Energy Efficient?

Oil filled heaters are extremely energy-efficient, since they use less electricity compared to other types of heaters. The best thing about oil filled heaters is that they are very durable.

These oil-filled heaters have instant heat that can be adjusted according to the needs and requirements of a particular room or area.

They also come with an automatic shut-off feature which will automatically turn them off after a certain time period if there is no one in the house.

This helps save on power bills as well as reduce wastage of fuel.

The most important advantage of these heaters is their ability to provide even heating throughout the entire space without any uneven temperature distribution.

These heaters do not require frequent maintenance, unlike gas-fired ones.

How oil filled space heaters work?

Spacer heaters have a supplementary heating source that provides additional warmth for your home. These supplemental sources include electric resistance wire coils, ceramic elements, halogen lamps, etc.

The main purpose of this extra heating element is to increase the overall efficiency of the heater by providing more heat than what would otherwise be provided by just using natural convection.

This means that you get better results at a lower cost.

In addition to this, it also increases the life span of the heater because it does not need constant attention like conventional heaters.

The vapor pressure and heat reservoir of the space heaters are maintained through the circulation of hot air from the top down.

It circulates around the bottom part of the unit where the combustion chamber resides.

When the flame burns inside the burner, it heats up the surrounding air causing it to rise upwards. As soon as the heated air reaches the uppermost portion of the unit, it gets cooled down again due to its contact with cooler ambient air. 

Benefits of using an oil-filled radiator?

There are many benefits of space heaters over traditional radiators. Some of those benefits are listed below:

  • They are much cheaper than regular radiators.
  • They are easy to install.
  • They are highly portable.
  • You don't need to worry about replacing filters regularly.
  • They are safe to operate.
  • They are eco friendly.
  • They are safer to handle.
  • They are easier to clean.
  • They last longer.

The downside of oil filled space heaters?

Space heaters have also a downside that you need to know before buying one. They may cause some problems such as:

  • If the thermostat setting is too high then the heat could burn out the wires. This problem occurs when the thermostat settings are set higher than normal.
  • Overheating can occur if the thermostat setting remains unchanged for long periods of time.
  • Some people find it difficult to control the amount of heat emitted by the heater.
  • Space heaters sometimes do not produce enough heat. In case of this situation, you should check whether the thermostat is properly connected to the electrical outlet. If it's not, replace it immediately.

How you know you need an oil-filled space heater?

When you are cold, your body temperature drops and your blood circulation slows down. Your brain also becomes less efficient when your body temperature is too low.

If you start feeling tired, dizzy, or weak, then you should consider buying oil-filled space heaters.

In the UK, many people use them in their homes during the winter season.
