The de-icer I purchased says it’s thermostatically-controlled. Why is it always running?

When backyard water features are home to year-round populations of fish, it’s vitally important to prevent long-term ice cover. Without a break in the ice, harmful gases produced by decaying leaves and other organic matter build up, threatening the well-being of wintering fish. To prevent that threat, many pond owners install thermostatically-controlled de-icers, which produce enough concentrated heat to keep a vent hole open during winter’s coldest months.
When a de-icer is thermostatically controlled, it is set to turn both on and off at certain temperatures. In theory, that makes good sense: if the water is cold, the de-icer goes to work, and when the water warms, it switches off – saving on unnecessary electricity costs. The problem, however, is that the water temperature in a frozen pond may not rise above the thermostat’s high-temperature shutoff threshold, leaving the de-icer in full heating mode all the time.
Naturally, we’ve given this issue some thought. And that’s why we strongly recommend the use of our Thermo Cube Thermostatically Activated Plug. Unlike a thermostatically-controlled de-icer, the Thermo Cube measures air – not water temperature. Thus, when the sun is shining, and air temperatures warm up, the Thermo Cube automatically cuts power to the de-icer, and turns it back on when the air temperature drops. The combination works flawlessly – applying heat when it’s required to keep the ice open, and shutting it off when it’s not.
Pond Talk: Do you use a thermocube along with your de-icer?
