ABSTRACT:
A thermostat control for use in conjunction with a boat dock de-icer, wherein the thermostat control includes an electrical outlet, a plug for connecting the control to a source of electrical energy, a set point controller for controlling the operation of the thermostat, and a temperature sensor for sensing a fluid. A conventional boat dock de-icer is plugged into the thermostat control and the thermostat control is connected to a source of electrical energy. The temperature sensor is placed in water in the vicinity of a boat dock, and the set point is set to any desired temperature, but preferably to a temperature about freezing. When the control temperature of the water is reached, the thermostat control permits operation of the boat dock de-icer, so that the de-icer operates only when needed, instead of continuously.
