Electric heaters are heating equipment that uses electricity as energy for heating and heating, and can also be called electric heaters. According to different heating materials, electric heaters can be divided into electric blankets, quartz tube electric heaters, fan heaters, air conditioners, electric oil heaters, etc. According to the different forms of heating, electric heaters are divided into two categories: thermal storage type and non-thermal storage type.
1. Heat storage type: The heat storage heater uses the low-cost electric energy during the trough period of the power grid at night (23:00 to 7:00 the day) to complete the conversion and storage of electricity and heat energy within 6-8 hours. During the period, the stored heat is released in the form of radiation and convection to achieve indoor heating throughout the day.
2. Non-thermal storage type: Most of the commercially available products are non-thermal storage type.
