FAQ

Q: What are the Operating Temperatures of an Immersion Heater?
Immersion heaters are available in many temperature ranges. The temperature an immersion heater can output depends on the supply voltage and the resistance (watts = voltage2/resistance). Industrial heaters can typically heat water to around 900°F (482°C) internally. The heat output will remain constant regardless of the environment or application since the heater’s resistance measurement is also constant.
