Autumn long rains, and then the first snow bring not only new impressions to our homes, but also make us think about heating. This is especially true for owners of apartments and houses connected to a centralized heating system, because not always the expectations of heat are justified. It is for this reason that a variety of heating appliances are popular. The species and models are huge, so it's no wonder that consumers are often lost in choice.
Despite the abundance of various types of heaters , at the peak of popularity there are oil heating radiators. Their principle of work on natural convection is based: the electric appliance heats the air in the room, which rises up, giving way to the cold one.
Design and operation principle of the oil cooler
Before choosing an oil cooler, you need to estimate the area of the room that you are going to heat, as well as the time required to reach the set temperature. After this, you can already select models of oil coolers with the necessary characteristics.
This household appliance is a sealed enclosure in which the heating elements are located. The remaining space is filled with mineral oil, which plays the role of coolant. The thermal conductivity of the oil exceeds the analogous index of air, therefore cooling of the heaters is effective. The obtained heat transfers the heat to the body from the metal, and it. In turn, it divides the heat with air in the room.
Regarding the radiator housing, it often consists of ribbed sections. They can be from three to fifteen. Note that with the same power of oil coolers, the number of ribs in terms of heat transfer is not important! The case of the device with a large number of sections will be less heated, but its weight and cost will increase. Another thing is if the power of the device, for example, has 9 ribs more than the model with 5 ribs.
Additional functions
Today, every self-respecting manufacturer of heating appliances is not limited to their main function, that is, in fact, heating. It is much more convenient and practical, when the radiator is equipped with a mode switch, as well as a temperature regulator. If the room is already warm enough, then it is possible to reduce power consumption by changing the operating mode due to the shutdown of one of the heaters. There are even models of radiators with thermostats, which allow to maintain the temperature set in degrees.
Regarding the placement of the heater in the room, then here you have a choice. In addition to the traditional floor, there are also wall-mounted oil electric heaters. They are appropriate in rooms that need constant heating.
Determining what type of oil cooler is better to buy, pay attention to such useful trivia as rollers to facilitate movement, handles, coils for the cord and even a hanging towel warmer!
It is worth noting that these reliable, fire-safe, noiseless and durable appliances have a number of drawbacks. They include a relatively large weight (up to 30 kilograms), a high temperature of the body heating, as well as slow heating. However, the last drawback is more than offset by the built-in fan heater.
