As the name suggests, a heater is a device that can emit warm air. Generally speaking, the temperature is about 40°C. It contains three parts: heat generation, blowing, and temperature and blowing control and protection. PTC is an abbreviation for ceramic heating element. It uses a fan to blow air through the PTC heating element to force convection, which is the main heat exchange method. It is equipped with a temperature limiter inside, when the wind is blocked by the fan, it can automatically cut off the power. Some are also equipped with a dump switch, which can automatically cut off the power when the heater is dumped. Its output power is 800-1200 watts, and the temperature can be adjusted at will. The air supply is soft during work, the temperature rises quickly, and it has an automatic constant temperature function. The PTC components are generally waterproof, so they are suitable for use in the bathroom. The price is 300 to 500 yuan. It is an ideal portable household electric heater.
