The choice of raw materials and workmanship of electric air heaters lead to different costs, leading to huge price differences. To

1. Why are there electric air heaters of different materials?

In order to form the so-called unique selling point of their own, some companies have chosen aluminum casings and used the toxic plastic casings as an excuse to vigorously promote aluminum casings. Therefore, there will be two types of air heaters.

2. Will an aluminum case be better than a plastic case?

Plastic is toxic! Is it true? As everyone knows, when the heater is working, the temperature of the air outlet exceeds 100 degrees Celsius, and the aluminum material will quickly transfer heat to the entire heater shell. And some vehicles will install the heater inside the cab, and the high temperature heater shell is very likely to cause burns to the people in the car (the consequences will be more serious than being scalded by boiling water). Even if the heater is not installed inside the cab, an object that is often maintained at more than 100 degrees Celsius under the car will accelerate the aging of the cables and rubber around the heater. It can be seen that the choice of aluminum housing for air heaters is very unscientific, so everyone needs to be cautious in selecting materials.
