ELIZ EURO 200 S21 | ELZ_3358

Product detailed description

The ELIZ EURO 200 S21 is commonly used in residential buildings, small businesses and multi-apartment complexes where a compact yet high-capacity water heating solution is required. It is suitable for ground-level installation and can be integrated into systems with multiple heat sources such as boilers and solar collectors. Installers typically handle tasks like verifying thermal balance, ensuring correct media connections and checking electrical safety standards. The unit’s design allows for efficient space utilisation while supporting simultaneous heating via electric and external heat sources.

Its dual heat exchangers and electric element make it ideal for installations where primary heating is provided by another system, with electric backup or auxiliary support. The system supports up to three heating media, allowing for flexible energy management. This makes it a versatile option for off-grid or hybrid systems where solar and boiler inputs are available alongside electrical heating. Installers should ensure that the system is correctly sized to match the building's hot water demand and that all media connections are compatible with the heat exchanger interfaces.

The technical parameters define the system’s compatibility with different heat sources and electrical configurations. The 3000 W electric element provides rapid heating when needed, while the two heat exchangers allow for simultaneous input from other sources. The maximum pressure rating of 8 bar ensures safe operation in pressurised systems. The IP 24 rating means the electrical components are protected against dust and splashing water, making it suitable for indoor installation. The surface areas and power ratings of the heat exchangers indicate their efficiency in transferring heat from external sources to the stored water.Installation and connection The ELIZ EURO 200 S21 is designed for ground-level installation and cannot be mounted on walls. The 3/4 inch threaded connections for both the heat exchangers and water supply lines must be verified for compatibility with the existing piping. Installers should ensure that the system is level and securely placed on a stable base to prevent vibration or movement during operation. The electric supply requires a dedicated circuit with a 16 A fuse and a 230 V connection. A safety cut-off is included to prevent overheating, and the thermostat allows for temperature control between 7°C and 75°C. Common installation errors include incorrect media routing, insufficient insulation around connections and failure to verify the grounding of the electrical system. After installation, the system should be tested for leaks, correct pressure and proper operation of the thermostat and safety features.Compatibility and accessories This model is compatible with a range of heating systems, including gas and oil-fired boilers, heat pumps and solar thermal collectors. The two heat exchangers can be connected to different sources simultaneously, enabling a hybrid heating strategy. For optimal performance, the system should be paired with a circulation pump and expansion vessel suited to the system’s pressure and flow requirements. No additional accessories are included in the standard package, but installers may need to order a separate control panel if advanced monitoring is required. The unit does not require a separate wall bracket, as it is designed for floor installation only.Technical background for designers The ELIZ EURO 200 S21 operates using a combination of direct electric heating and indirect heat transfer through two separate heat exchangers. The heat exchangers are constructed from steel with a zirconium enamel coating, which resists scaling and corrosion. The tank itself is also made from steel with the same protective coating, ensuring long-term durability. The system integrates into larger heating circuits by connecting the heat exchangers to external heat sources such as boilers or solar collectors. The thermal efficiency is enhanced by the thick polyurethane insulation, which minimises heat loss and reduces the frequency of reheating cycles. The placement of the heat exchangers and the electric element inside the tank allows for even heat distribution and rapid response to demand changes. The system’s longevity depends on regular maintenance of the anodes and the integrity of the enamel coating on the internal surfaces.Service and operation The ELIZ EURO 200 S21 requires periodic inspection of the anodes and internal tank condition to ensure continued protection against corrosion. The anodes are sacrificial and should be replaced when they show signs of depletion. The thermostat and safety cut-off should be tested regularly to confirm they respond correctly to over-temperature conditions. The system’s insulation should remain intact, and any signs of damage should be addressed promptly to maintain efficiency. The ECO mode helps reduce energy consumption by limiting the maximum temperature to 55°C, which is sufficient for most domestic uses. The indicator light on the switch provides visual confirmation of the heating status. No specific service intervals are outlined in the provided information, but the 5-year tank warranty indicates that the tank is expected to last significantly longer than the standard 2-year product warranty.Frequently asked questions

Can the ELIZ EURO 200 S21 be connected to both a boiler and a solar system at the same time?
Yes, the unit has two heat exchangers that can be connected to separate heat sources simultaneously, such as a boiler and a solar collector.

Is it possible to adjust the minimum temperature setting for frost protection?
The thermostat has a minimum setting to prevent freezing, but the exact value is not specified. It functions as a built-in frost protection mechanism.

What is the purpose of the two anodes included in the system?
The two anodes provide dual corrosion protection for the tank, extending its lifespan and reducing the risk of internal damage due to water chemistry.

Can the ECO mode be used continuously without affecting hot water availability?
Yes, the ECO mode limits the water temperature to 55°C, which is adequate for most domestic applications and reduces energy consumption without compromising hot water supply.
