These are the safest submersible aquarium heaters we could find in the market today. They are completely submersible, UL-approved, salt water compatible and shatterproof! Instead of the typical metal element in a breakable glass tube, they utilize a polymer sheet that uniformly heats a shatterproof glass tube. The temperature is controlled and maintained by a highly precise micro-switch controller, adjustable from 70 to 89ºF. 115V/60 Hz with a 6' cord. One-year warranty. Made in Italy.
