The Schego Pond Heater protects the garden pond for complete freezing during permanent temperatures under 0C. Even in winter, life continues in the garden pond. If it freezes over, however, the ongoing decay of dead plants, etc., can lead to the production of toxic gases that are poisonous to water animals and pond plants. By installing the Schego Pond heater, you can ensure an ice-free area even during periods of severe frost, so that the toxic gases can escape and an exchange of gases take place. The size of the ice-free area depends on the wattage chosen and the ambient temperature. It is independent of the size of the pond. The limited local heating and the silent function of the pond heater means that natural life cycles of the pond inhabitants can continue without disturbance.technical Data Schego Pond Heater:100 W, Length 250 mm, Diameter 25 mm, incl.
