Real Installation Cases – ICCP Active Anode in Water Heaters
Proven Solutions in Real Operating Conditions
This section presents typical real-world examples of ICCP active anode installations in residential and commercial water heaters.
Each case demonstrates practical implementation scenarios, installation conditions, and key technical considerations.
Note: These cases are illustrative. Exact system configuration (potentiostat model and electrode type/length) must be verified according to the tank’s technical data and manufacturer selection tables.

Case 1: Standard Retrofit (Top Port Replacement)
Typical for: Residential enamelled steel tanks (120–300 L) with top anode port (G ¾” or G 1″)
- Tank type: Enamelled steel
- Installation: Replacement of magnesium anode via top threaded port
- Electrode: TA series (typically 200–400 mm depending on tank size)
- Potentiostat: Standard plug-in unit (2.3 V setpoint)
Key details:
- Direct retrofit without tank modification
- Adapter sleeve ensures electrical isolation
- Ground connection made to bare metal surface
Result: Stable corrosion protection without periodic anode replacement.
For precise system selection, refer to our Technical Specifications and Selection Table.
Case 2: Retrofit with High Sludge Formation and Odor Issues
Typical issue: Magnesium sludge accumulation and recurring odor
- Tank type: Enamelled steel
- Condition: Heavy sediment buildup at tank bottom
- Previous system: Magnesium anode with recurring sulfur odor within short operating cycles
Observed problems:
- Reduced heating efficiency
- Unpleasant odor in hot water
- Frequent maintenance required
ICCP installation:
- TA series electrode installed via top port
- Potentiostat connected to tank shell (bare metal)
- System activated after flushing tank
Result:
- Elimination of anode-derived sludge
- Improved operating conditions over time
- Reduced maintenance frequency
For precise system selection, refer to our Technical Specifications and Selection Table.
Case 3: Side Mounting Installation
Application: Tanks without accessible top anode port
- Tank type: Enamelled steel
- Installation: Side inspection flange (insulated M8 mounting)
Key technical points:
- Requires careful electrical isolation of the electrode from the tank wall
- Ground connection ensures current flow through water
- Suitable for retrofit in older tanks
Result: Full ICCP functionality achieved despite non-standard mounting location.
For precise system selection, refer to our Technical Specifications and Selection Table.
Case 4: Stainless Steel Tank Protection
Application: Stainless steel tank in aggressive water conditions (e.g. elevated chlorides)
- Tank type: Stainless steel
- System type: Stainless-optimized potentiostat (1.9 V setpoint)
Key technical points:
- Lower setpoint (1.9 V) helps prevent over-protection in stainless steel tanks
- Helps reduce hydrogen evolution
- Supports long-term integrity of stainless steel alloys
Result: Stable protection in conditions where sacrificial anodes may be less effective.
For precise system selection, refer to our Technical Specifications and Selection Table.
Case 5: Multi-Electrode System (Large Tank)
Application: Commercial or large-capacity hot water systems
- Tank type: Enamelled steel
- Configuration: Multiple TA series electrodes for uniform current distribution
- Potentiostat: Higher nominal current output depending on system size
Key technical points:
- Multiple electrodes ensure uniform protection across large surfaces
- Electrode placement adapted to tank geometry and heat exchangers
- Required for larger volumes and complex internal layouts
Result: Uniform corrosion protection across entire tank volume.
For precise system selection, refer to our Technical Specifications and Selection Table.
Case 6: Retrofit with Limited Technical Data
Typical situation: Missing documentation or unclear tank specifications
- Tank type: Not fully identified
- Installation based on visual inspection and standard configurations
Approach:
- Thread size identified visually (e.g. G 1″)
- Tank volume estimated
- Standard ICCP system selected based on typical parameters
Recommendation:
The data plate is the “DNA” of your tank. A clear photo allows accurate identification of tank type, volume and configuration for proper system selection.
Result: Successful installation with stable system operation.
For precise system selection, refer to our Technical Specifications and Selection Table.
What These Cases Show
- ICCP systems can be retrofitted into most existing tanks
- Installation is compatible with standard European connections
- System performance is stable across different water conditions
- Monitoring via potentiostat provides continuous status visibility
- Correct system selection depends on tank volume, material and number of heat exchangers
