[Fast Heating] Can make 5 gallons of water warm in a few minutes. Before inserting the heater, please ensure the heater is completely immersed in water then connect the power supply. [Premium and Safe] With stainless steel protective cover, submersible water heater effectively prevents heating elements from direct contact with people or animals.
