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
