Pond heater Eheim Thermo 200

The Eheim product is a stainless steel heater. It prevents the freezing of the pond surface down to -20°C.

The surface of the garden pond should never completely freeze, as toxic gases can get trapped under the ice. The EHEIM heater prevents the pond surface from freezing (down to -20°C), allowing toxic gases to escape and vital gas exchange to take place at the water's surface.

The product ensures a continuous supply of oxygen for the fish and microorganisms.
