Active Anode Installation Gallery – ICCP Retrofit Examples
Real Installation Cases of ICCP Active Anode Systems
This gallery presents real-world installations of ICCP active anode systems in residential and commercial water heaters across Europe.
All examples follow correct installation practices according to DIN 4753-3, including electrical isolation, grounding and continuous potentiostat operation.
Installation Cases
Case 1: Standard Retrofit (G ¾” – G 1¼”)
Typical for Buderus Logalux, Viessmann Vitocell, and Vaillant storage tanks. Replacement of a magnesium anode in the top port using standard thread sizes.
Case 2: Side Mounting (Inspection Port)
Common in systems where the top port is not accessible, including various Buderus, Viessmann and Vaillant configurations. Installation is performed through a side inspection opening with proper sealing and electrical isolation.
Case 3: Stainless Steel Tanks
Installation in stainless steel tanks with adjusted parameters. Proper electrical isolation and controlled output prevent hydrogen evolution and ensure the long-term integrity of the stainless steel alloy.
What to Look For in Each Installation
- Insulation check: Look for the plastic insulating sleeve – it prevents the protective current from short-circuiting through the tank thread
- Grounding (mass): Note the ground cable connecting the potentiostat to the tank shell – this completes the protection circuit
- Note: The ground connection must be made to a bare metal part of the tank (e.g., a bolt or a specifically cleaned surface) to ensure low electrical resistance
- Correct electrode positioning: The titanium electrode must be fully immersed and properly aligned inside the tank
- Potentiostat status: Green LED indicates active protection; incorrect indication requires inspection
LED Status Guide
- Steady Green: System OK, tank protected
- Flashing / Red: Connection fault, short circuit, or no water in the tank
- No Light: No power supply
Magnesium vs Titanium – Visual Comparison
Why wait for failure? A depleted magnesium anode (left) stops protecting your tank long before visible corrosion appears.
The mixed-oxide-coated titanium electrode (right) does not dissolve and provides stable protection throughout the tank lifetime.
Typical Wiring and System Layout
- Connection of the titanium electrode to the potentiostat
- Ground cable connection to the tank body
- Continuous power supply via standard EU plug
Correct wiring ensures accurate measurement of the protective potential and proper current delivery.
