Arab weather - With the entry of cold weather, the topic of choosing the appropriate heating method becomes one of the most important topics that occupy a lot, each has its own criteria that govern its choice in light of the multiplicity of means and systems used for this, as heating methods differ in their efficiency compared to their financial cost in terms of purchase price or cost operation, and the means differ in terms of their compatibility with environmental standards and the extent of their safety for human health.
The following is a simplified explanation of the principle of operation of the most common home heating devices:
Thermal radiators are central heating systems that work indirectly on the combustion of fuel, and radiators are metal objects installed on the walls of rooms, in which hot water (or hot water vapor) circulates through exposed tubes, and some of them are equipped with blades to increase the surface area, and the idea of thermal radiators is based Transferring thermal energy from the hot medium to the perimeter of the room, where the heating process begins from the boiler , which heats the water through the combustion of fuel (diesel or gas), then moves to the radiators, and after it releases its heat and cools, it moves downward to exit from The radiator is passed through a special tube through which it returns to the boiler to be heated again.
Some of these heat radiators use hot water to reach them from the boiler with the help of pumps, and some use water vapor, which moves through the pipes under a certain pressure without the need for pumps.
This heating system is characterized by a low operating cost in relation to its ability to distribute heat to several parts of the house or building at the same time, and radiators can be closed in some rooms to save energy.
Gas fireplaces and kerosene heaters are considered one of the traditional methods of heating, as gas heaters depend on the flame of fire resulting from gas combustion, including mobile types, and other types installed in the wall in the form of a stone stove, to match the decor of the place, and kerosene heaters share with them in terms of their dependence on a flame The fire resulting from the combustion of kerosene, and when using this type of heater, care must be taken to leave an outlet for air to circulate in the room, and not to approach the heater from flammable objects or furniture.
There are many types and shapes of electric heaters available in the market, including oil heaters, halogen and carbon heaters, and fan heaters, but in general electric heaters depend on the principle of heating by electrical resistance, that is, converting electrical energy directly into thermal energy that radiates in the place to warm it, so some types may consume A greater amount of electrical energy, so you should pay attention when choosing the right type of electric heater to its efficiency against electricity consumption, and the safety features available in it, but this type of heaters is characterized by its lightness, and the ability to move it and change its place easily as needed, and some of them are equipped with the feature of rotation or fans. to distribute the heat.
Some home air conditioners have the feature of heating the air to be used in the winter, and most of these air conditioners use the opposite method of cooling to bring out warm air in the winter, and some of them depend in the heating process on the principle of electrical resistance, by passing the air through a metal wire that heats up when an electric current passes through it The air is heated, and hot air is released into the room.
It is a heating panel that uses a modern technology to heat the place, as infrared heating panels simulate the way in which sunlight heats the surface of the earth, as these panels use electrical energy to produce infrared radiation, which spreads in the place to heat solid objects, and when the objects are heated, the air is heated surroundings, and thus the room is heated. It is worth noting here that infrared rays are invisible electromagnetic waves, but humans can feel them in the form of heat, through which heat is transferred from various thermal energy sources, such as the sun and fire.
Modern wood-burning stoves add an extra touch to the home décor, and have many advantages, such as: Provides comfortable warmth and romantic ambiance - It works when the electricity is cut off - The fire can be used for cooking - Inexpensive such as electric heaters or fossil fuels (kerosene or diesel).
Although wood stoves are great, they can involve several risks, such as the possibility of fire, so safety measures must be taken, and the chimney is cleaned and checked regularly by professionals.
