ELIZ EURO 200 S1

Product detailed description

This water heater is commonly installed in residential and commercial buildings where a reliable supply of domestic hot water is required. It supports hybrid operation using either the electric heating element or an external heat source via the heat exchanger. The unit is suitable for integration into central heating systems, solar thermal systems, or heat pump configurations. Installers should ensure correct positioning and secure mounting to accommodate the unit’s weight and dimensions.

The design allows for simultaneous electric heating and heat transfer from an external source, making it ideal for systems with variable energy inputs. The unit must be installed in a stable, dry location with access to electrical and plumbing connections. The free-standing construction allows flexibility in placement, provided the floor is level and load-bearing. The tank and heat exchanger are protected against corrosion with enamel coating and anodized protection.

Technical parameters

The 2000 W electric heating element allows rapid heating, while the 25 kW-rated heat exchanger supports integration with higher-capacity heat sources. The IP24 rating ensures protection from splashing water, and the 6 bar maximum tank pressure must be considered during system design. The 3/4 inch inlet and hose connection facilitate standard plumbing fittings. The 6.3-hour heating time from 12°C to 65°C is relevant for system sizing and energy planning.

Installation and connection

Installation begins with securing the unit on a flat surface and connecting the cold water inlet (3/4 inch) to the mains supply. The hose connection (3/4 inch) is reserved for the external heat source. The electric supply requires a 230 V, 10 A circuit with a separate fuse and switch. A minimum clearance of 5 cm around the unit is recommended for ventilation and maintenance. The circulation port in the middle of the tank allows for installation of a circulation loop if needed.

Key checkpoints include verifying the electrical connection, confirming the pressure relief valve is functional, and testing the thermostat range (10–75°C). Common errors include incorrect hose orientation, missing insulation on exposed pipes, and failure to ground the unit properly. The safety cut-off and thermostat must be tested after installation to ensure they respond correctly to overheat conditions.

Compatibility and accessories

This model is compatible with central heating boilers, solar thermal collectors, and heat pumps. It requires a dedicated electrical circuit and a standard plumbing setup. Additional components such as expansion vessels, circulation pumps, and control systems may be necessary depending on the system configuration. No related products are listed for this model.

Technical background for designers

The unit operates by heating water either through the electric element or via thermal conduction through the heat exchanger. The internal tank and heat exchanger are made from steel and coated with a zirconium-enriched enamel to resist corrosion. The 75 mm thick polyurethane insulation minimizes heat loss. System efficiency depends on the external heat source’s capacity and the accuracy of the thermostat settings. The dual magnesium anodes provide sacrificial protection to the tank, extending its service life.

Designers should account for the unit’s 65 kg mass when planning support structures. The 600 x 1450 mm dimensions require sufficient space for access and maintenance. The heat exchanger’s 0.90 m² surface area ensures efficient heat transfer from external sources. The unit integrates well with smart thermostats and control systems via the dedicated sensor ports.

Service and operation

Periodic checks should include inspecting the pressure relief valve, verifying the functionality of the thermostat and safety cut-off, and ensuring the anodes are intact. The enamel coating and anodized protection reduce the need for frequent maintenance. No specific service intervals are mentioned in the brief. The unit includes a thermal fuse to prevent overheating and a water-resistant switch with indicator light for operational status.

Frequently asked questions

Can the ELIZ EURO 200 S1 be connected to a solar thermal system?
Yes, the unit is equipped with a heat exchanger for integration with solar collectors or heat pumps. Ensure the external system provides sufficient flow and temperature for effective heat transfer.

Is it possible to use the electric heating element and external heat source simultaneously?
Yes, the design allows for concurrent operation of the electric element and the heat exchanger. This enables faster heating and more flexible energy use depending on availability.

How does the thermostat function in this model?
The thermostat controls the electric heating element and can be set between 10°C and 75°C. It does not regulate the external heat source, which must be managed separately.

What is the purpose of the two magnesium anodes in the tank?
The anodes provide sacrificial protection against corrosion, reducing the risk of tank degradation from water impurities. They help extend the tank’s lifespan under normal operating conditions.
