State of the art carbon fiber heating technology radiates infrared waves creating uniform heating with not hot spots. Carbon fiber is an energy-efficient method for heating with no wires that might become pinched or broken and create a safety hazard. This safe and efficient material regulates itself to a maximum safe temperature of 113F without a sensitive thermal switch which can fail causing overheating. Each unit has an adhesive backing to keep it in contact with the tank for optimum heat transfer.
