Titanium Heater
This heater uses titanium tubing for fast heat conduction. The titanium tubing resists corrosion caused by salt water or PH fluctuation of water and will not crack due to impact or high temperature. The heater has a built-in temperature sensing switch; if the heater accidentally is exposed to open air during heating process, the temperature sensing switch will automatically cut off the power. After the heater returns back to normal temperature, it will then resume it's heating process.
