Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection and energy-saving equipment, and in particular relates to a heat storage type electric heater. Background Art

[0002] Heating can be divided into water heating and gas heating. Usually, the radiator we refer to is water heating, which uses a wall-mounted boiler or boiler to heat circulating water, and then connects it to the radiator through a pipe. Finally, the radiator outputs the appropriate temperature to form an indoor temperature difference, and finally performs a heat cycle to evenly increase the temperature of the entire room. Gas heating heats the air, and the cold air is heated by the radiator into hot air. The hot air rises and forms convection with the cold air in the room. The cold air circulates to the vicinity of the heater and is heated into hot air. The hot air circulates in the house, and the room becomes warm.

[0003] Traditional heaters all use coal as a heat source. In order to respond to the requirements of environmental protection policies such as reducing coal consumption and building clean energy, and to effectively improve air quality, combined with the needs of the "coal to electricity" project, the utility model provides a heating product suitable for "coal to electricity" and energy saving and environmental protection - a heat storage electric heater, which is used to replace traditional coal stoves for heating and meet the different needs of people for heating in winter.
