Thermostat Control: The built-in thermostat control has a range from 41°F-59°F (5°C-15°C), automatically turning the heating pad on at 41°F and off at 59°F to prevent freezing and conserve battery power while supplying water.
High Efficiency: Quality heating wire is closely arranged for improved heating, with 6mm thick insulation for better heat retention.
Temperature Protection: An internal temperature protector will immediately cut off power if the temperature exceeds 158℉ (70℃) due to abnormal reasons, using flame-retardant material for protective foam.
Wide Application & Easy Installation: Measuring W 12" x L 18", it's suitable for various tanks and easy to install in caravans, campers, trailers, motorhomes, boats, and marine vessels with just a few steps.
Attention: The heating pad operates at 120V with a 10-foot power cord and 45W output, and requires water in the tank while in use.
