Description
The OASE IceThermo 200 is a thermostatic pond ice prevention device designed to protect fish and maintain healthy water conditions during freezing temperatures.
Unlike passive systems, IceThermo uses a controlled heating element that activates automatically when temperatures fall, ensuring a small section of the pond remains ice-free.
This open water area allows harmful gases to escape and oxygen to enter the pond, which is essential for koi and stocked garden ponds during winter.
The thermostatic control ensures the system only operates when needed, helping to reduce unnecessary energy use.
Typical Applications
- Koi ponds
- Garden fish ponds
- Cold climate pond protection
- Winter fish safety systems

How It Works
The IceThermo 200 monitors ambient water temperature and activates a heating element when freezing conditions are detected.
This prevents a small area of ice from forming, ensuring continuous gas exchange between the pond and atmosphere.
