The cast aluminum heater has fast thermal conduction and low temperature resistance. The price is more expensive than the other two
Ceramic heaters generally have a better thermal conductivity price than the cheap insulation effect of cast aluminum, and they are not afraid of leakage
Stainless steel heaters are generally stainless steel heating tubes or mica outer stainless steel, the former heating temperature is higher than the latter. Stainless steel heaters should be the cheapest of the three!
Now there is an electromagnetic heater that heats faster, has little thermal inertia, and can be controlled with high precision. Can reduce the ambient temperature!
