Protective anodes
Protective anodes are essential components for the long-term protection of hot water storage tanks in heating systems. These anodes are installed inside the tank to prevent corrosion of internal metal surfaces by sacrificial electrochemical action. The category includes both traditional sacrificial anodes and electronic variants, suitable for a range of tank sizes and system configurations.
Products in this category are designed for compatibility with storage water heaters and are commonly used in residential and commercial heating systems. They are available in different lengths and connection types to suit various tank dimensions and installation requirements.
How to choose
- Confirm the tank’s internal diameter and select an anode with a matching outer diameter (e.g., 32mm) and length (e.g., 400mm or 700mm) for proper fit.
- Verify the connection type, such as 6/4" plug, to ensure compatibility with the tank’s inlet or outlet.
- Choose between sacrificial anodes (e.g., IVAR.AM) or electronic anodes (e.g., IVAR.AE) based on system design and maintenance preferences.
Frequently asked questions
How often should a sacrificial anode be replaced?
Replacement frequency depends on water hardness and usage. In hard water conditions, anodes may require inspection and replacement every 2–5 years.
Can an electronic anode be used with all tank types?
Electronic anodes require a power supply and are compatible with tanks that support their installation. Always refer to the manufacturer’s technical documentation for compatibility.
