These keep your home warm for a very long time and are used by many people. These heaters are great for any sort of home, and all you need is electricity.

Are oil-filled heaters efficient?

How to choose an Oil Filled Heater

In order for the radiator to last a long time and not cause a burn or fire, it is important to take into account many parameters. We will tell you how to choose an oil heater, and what technical characteristics to pay attention to.

  • Power. When choosing a model, first of all, consider the power of the device. To do this, use a simple formula: heating 1 sq. m requires a minimum of 100 watts. So you can calculate the power of the radiator for a room, kitchen, corridor. When choosing a heater for a balcony, multiply this value by a factor of 1.15–1.2.
  • Heater section dimensions (width and thickness). These figures should be average, since too thick sections take a long time to warm up, which negatively affects energy consumption. At the same time, narrow elements heat up faster but have low heat transfer.
  • Device weight. It should be taken into account that, due to the design features, oil heaters cannot have a small mass. A lightweight radiator can be made of thin, low-quality metal, or the volume of the coolant (oil) in it will be less than it should be.
  • Control method. Simple and inexpensive heaters are usually reliable mechanical controls for temperature and power selection. On more expensive models, manufacturers install adapters for remote control via a mobile application. A device with a control panel is slightly cheaper, but inferior to the mechanical control method in terms of reliability.
  • Useful functions. The thermostat not only extends the service life of the device but also protects the heater from overheating and saves electricity. When the temperature drops, it will turn on the built-in heating element to heat the oil, and after heating, it will temporarily turn off the device. Radiators without a fan will take longer to warm up the room. Such devices are usually chosen for an apartment with good thermal insulation.

It is better to put heaters with a fan in a corner room or a room with poor central heating batteries – the air will circulate and heat up faster. For a home or summer cottage, radiators with an anti-freeze function are suitable. Such devices will maintain a positive temperature until the owners return home. In the bath or kitchen, where there is high humidity, it is better to choose models with a waterproof case.

Some manufacturers produce compact tumble dryers that can be mounted on a radiator. And with the humidification function, the heater combines the capabilities of two devices: a mobile heating radiator and an air humidifier.
