Oil heater - a budget and reliable way to individually heat in cold weather. Among the many models there are oil heaters for both permanent and occasional use
Principle of operation
Oil heater - a metal case resembling a standard battery, which is complemented by a special oil and heating element. When the heater is turned on in the electric network, a special heating element, the heater, is put into operation, it heats the oil to the required temperature. Then, the oil inside the device begins to heat the metal shell with its heat, which, in turn, heats the air in the room. All modern models of oil coolers are equipped with several modes. Therefore, the intensity of air heating can be adjusted independently.
How much oil is required?
The oil in the heater should completely cover the surface of the heating element, which is usually installed in the upper part of the metal housing. Or this is one empty section of 9. Thus, the volume of oil in the heaters is about 90% of the body volume.
What kind of oil to fill in the heater
For a heater of this type, both transformer oil and mineral oil are suitable. Transformer oil has good thermal conductivity and retains its properties up to -40 degrees. It is made from petroleum products by distillation. Based on the quality of the initial product, the oil may not have significant differences. Therefore, they can be mixed with each other.
Mineral oil in terms of viscosity is similar to transformer oil, which is able to provide a normal flow of convective particles in the tank when heated. Filling synthetic gear oil into the device due to its lower viscosity will provoke a higher noise level of the radiator. It is not recommended to fill engine oil with oil heaters because of its high viscosity, this can lead to overheating of the equipment.
