ICCP Systems for Reliable Corrosion Protection
AnodeTech offers complete ICCP systems consisting of a mixed-oxide-coated titanium electrode, intelligent potentiostat and full installation kit.
AnodeTech covers compact electronic titanium-anode systems for domestic and commercial hot-water storage tanks. Here, ICCP describes the underlying impressed-current principle; marine, pipeline and concrete systems are different applications with different design rules and standards.

System Selection by Tank Volume and Type
Selection of the correct ICCP system depends on tank volume, material (enamelled steel or stainless steel) and number of heat exchangers.
Specific system recommendations (potentiostat model + number and length of titanium anodes) are provided in the detailed selection table and depend on tank volume, material, and number of heat exchangers.

System Components
Mixed-Oxide-Coated Titanium Electrode (TA)
- Non-sacrificial design
- MMO (Mixed Metal Oxide) coating ensures high current density and uniform distribution, even in tanks with complex internal geometries (multiple heat exchangers)
- Multiple electrodes can be used in larger tanks for uniform current distribution
Potentiostat
- Automatic regulation of protection current
- Maintains required protective potential
- LED status indication
- Designed for continuous operation
The potentiostat operates in a duty cycle, measuring the tank potential and adjusting the output current at millisecond intervals.
Installation Kit
- Adapter configurations are compatible with most models from Buderus, Viessmann and Vaillant that use common European anode ports. Exact fit must be confirmed for the tank model, thread, port position, electrode clearance and manufacturer instructions.
- Electrical isolation components for correct installation
- Connection cables and mounting accessories
Ready-to-install kit: includes pre-assembled cabling, mounting hardware and detailed multi-language manual.
Selection Criteria
- Tank volume — determines required current output
- Tank material — enamelled steel or stainless steel
- Number of heat exchangers — affects internal surface area
- Water conductivity — influences protection current demand
View technical specifications and selection table →
Compatibility
- Enamelled steel tanks
- Stainless steel tanks (with adjusted parameters)
- Horizontal and vertical installations
- New installations and retrofit systems
Performance Characteristics
- Automatic regulation via potentiostat
- Continuous protection without degradation of electrode material
Installation Options
- Sleeve (muffen) mounting – replacement of magnesium anode
Proper installation requires electrical isolation and continuous power supply.
Important: The potentiostat must remain continuously connected to the mains. Disconnecting it immediately stops corrosion protection.

For specified water-heater systems, 2.3 V and 1.9 V are nominal potentiostat setpoints for particular configurations, not universal tank potentials. Actual drive voltage and protective current depend on the model, water conductivity, tank geometry and manufacturer approval.
No scheduled sacrificial-anode replacement is required, but the system is low-maintenance rather than maintenance-free: inspect the LED, cables and connections as specified by the manufacturer. Electricity consumption is low but model- and operating-condition-dependent.
Adapters are available for common European thread sizes, but compatibility must be verified for the exact tank model, port, internal geometry and manufacturer instructions. The functional tank/cathode connection is distinct from the appliance protective-earth (PE) conductor.
Where stated in the model datasheet, the control unit uses Class II protective insulation. Class II is not an IP enclosure rating.
DIN 4753-3 is relevant to corrosion protection of enamelled hot-water storage tanks, but compliance and system sizing must be confirmed for the exact tank/anode combination. Tank volume alone is not sufficient for selection.
Voltage, current, electrode length, temperature, pressure, enclosure rating and power-consumption values must be taken from the datasheet of the exact product; generic values are not binding.
