The English word for electric heater is \"electric heater\". An electric heater is a device that converts electrical energy into heat energy. It is used to provide warmth in a room or space. There are different types of electric heaters, including convection heaters, radiant heaters, fan heaters, and oil-filled heaters.
Convection heaters work by heating the air in a room. They have a heating element that heats the air, which then rises and circulates around the room. Radiant heaters work by emitting infrared radiation, which heats objects and people in the room directly. Fan heaters work by blowing air over a heating element, which then circulates the warm air around the room. Oil-filled heaters work by heating oil that is sealed inside the heater. The oil then radiates heat into the room.
Electric heaters are popular because they are easy to use and can be very efficient. They are also portable, so they can be moved from room to room as needed. However, they can be expensive to run, especially if they are used for long periods of time. It is important to choose the right size and type of electric heater for your needs, and to use it safely to avoid the risk of fire or other hazards.
