We choose oil heating radiators for homes and apartments

Heating

How to quickly heat a room if central heating fails? You can use various electrical devices, but the trouble is, they quickly burn oxygen in the room (we are not talking about infrared equipment). This is especially noticeable with devices with an open heating filament. Today, the “guests” of our article will be floor and wall mounted oil radiators that do not have this problem.

In the photo - various types of oil heaters

Before starting the review, I would like to say that this equipment will not force you to give all your earned money for heating, thanks to the installed thermal sensor. You will only need to correctly calculate the number of sections on the device.

Kinds

The work scheme of any oil heater is of the same type:

  1. The basis is sealed steel or aluminum housing.
TEN for heating the coolant
  1. Inside there is a conventional tubular heating element with a spiral inside, which is immersed in mineral oil.
  2. After turning on the power supply, the heating element heats up the oil and due to the occurrence of convection currents, heat is evenly distributed over the surface of the device.
Device design
  1. A regulator is installed in the power supply circuit of the heating element, which has either two positions (less or more heating) or a rheostat (a smooth increase or decrease in power). Both variants act simultaneously as thermostats. When the device reaches the set temperature, it turns off, and after a while it turns on again. Staged power controls with specified parameters can also be installed.

Different wall devices from the floor only mount. In addition, a large number of models can be universal, for them, specifically in the kit there are brackets for installation work of various types. You can easily fix them with your own hands.

In fact, you are presented with a conventional mobile radiator, where the coolant is oil, and the source of energy is electricity.

Tip: some models are equipped with additional options that allow you to program the device for a day, control the radiator remotely (remote control), and also conduct visual monitoring of the temperature through a digital indicator.

The price of heaters is not so high, it depends on its size, installation, number of sections and additional options (find out here what the steel radiators are Kermi).

Principle of operation of the device

Pros and cons of devices

Any equipment has positive and negative qualities, so they need to know before you go to the store for the goods:

Positive
  1. Oil cooler has a low surface temperature. This is facilitated by the coolant and the regulator, which do not allow heating elements to heat up to 800? С. A large surface area of ​​the radiator, as well as oil, reduce the dangerous temperature to 50-70? С. The consumer may not be afraid of a fire, and oxygen will not be burned out from the atmosphere of the room.
  2. Great inertia. This gives the effect of smoothing temperature fluctuations during operation of the thermostat. It will drop to the lower critical level for a few minutes.
  3. Corrosion protection. Oil as a coolant completely eliminates the appearance of rust.
Negative
  1. Safety of operation of the device depends, first of all, on the quality of its production. Oil expands when heated, so when a marriage is in the case, the heater explodes, spraying it. Even if there is no one in the room at this moment, the consumer is unlikely to be happy about this circumstance.
  2. The convection idea today is no longer among the most efficient heating systems. Heated from the oil heater air rushes up. Therefore, the main heat accumulates under the ceiling, at the same time at the bottom of the room the temperature may be 5-10? С below.

How to choose an oil cooler

Specifications

  1. Using the built-in thermostat system allows you to actually save electricity. The device in this case will give only as much heat energy as is necessary to maintain a comfortable temperature. The use of manual adjustment of the rheostat will not allow you to accurately maintain the optimal microclimate, since the temperature in the room also depends on the weather outside the window.
Heater temperature and power control unit
  1. We recommend to refuse cheap devices of little-known manufacturers, simply for security reasons. In addition, the calibration of the thermostat in them does not meet the realities.
  2. Although digital stuffing improves the comfort of operation of the device, many believe that this reduces its reliability. A conventional bimetal plate relay, which works flawlessly, will be quite enough. The microprocessor does not like elevated temperature, so their life is greatly reduced with constant heating.

Power

Below is a guideline for its selection:

  1. In standard dimensions, the height of the room is 2.5 m. In this case, 1 kW of energy is enough to heat 10 m.2 the premises. For example, a 2.5 kW device is designed for installation in a room of 25 m2.
  2. Another way to count, if you have a non-standard ceiling height, the following - by 1 m3 required to spend 40 watts.
  3. In contrast to an apartment, in a private house it is necessary to add 50% to standard calculations, since it has exterior walls, not warm neighborhood apartments.
Properly selected oil heater will create a comfortable temperature in the room

Light: in the northern regions, to the standard figures should be added coefficients 1.5-2, which depend on climate.

Conclusion

The oil radiator at the time was an interesting additional device that made it possible to get a comfortable temperature in the room if the central heating did not fulfill its task. The main thing is to correctly calculate the power of the device relative to the area of ​​the room (see also the article Vertical heating radiators - a combination of beauty and efficiency).
