ELÍZ EURO 120 X | ELZ_3310 | Electric horizontal water heater

Product detailed description

Horizontal electric water heaters are commonly used in residential and small commercial buildings where space is limited and accessibility is required. This model is particularly suited for installations where the heating system requires a compact, wall-mounted solution with high thermal efficiency and precise temperature control. The ELIZ ELÍZ EURO 120 X integrates well into central heating systems, domestic hot water circuits, and small-scale plumbing applications. It is typically installed in utility rooms, boiler rooms or service areas, and should be mounted securely to prevent vibration and ensure stable operation. The left-side water connections allow for straightforward integration with existing pipework and fixtures.

The model is ideal for systems where rapid heating is required, with a standard heat-up time of 3.8 hours from 12°C to 65°C. It supports both point-of-use and distributed hot water applications and is compatible with standard electrical and plumbing infrastructure. Its low thermal losses and ECO mode make it suitable for energy-conscious installations. The design also allows for easy access to controls and safety components, facilitating routine checks and maintenance.

The power rating of 2000W at 230V determines the required electrical circuit capacity and fuse size during installation. The maximum pressure rating of 6 bar indicates the system’s hydraulic limits and must be considered when connecting to mains or pressurised water supplies. The IP24 rating means the electrical enclosure is protected against solid objects larger than 1 mm and splashing water, which is suitable for dry indoor environments but not for direct exposure to rain or high humidity. The 3.8-hour heat-up time is relevant for system sizing and determining the appropriate storage volume for peak demand periods.

Installation and connection

Mounting the ELIZ ELÍZ EURO 120 X requires securing it horizontally to a wall using the provided bracket. The water inlet and outlet are 1/2 inch threaded ports located on the left side of the unit. Installers must ensure the wall is structurally sound and capable of supporting the unit’s weight of 34 kg. A minimum clearance of 10 cm around the unit is recommended for ventilation and access to controls.

Electrical connections must be made via a dedicated 230V supply with a 10A fuse. The IP24-rated housing protects internal components from dust and splashes but does not allow for outdoor use. Before commissioning, verify the integrity of the water supply, pressure stability and correct orientation of the built-in check valve and pressure relief device. Common installation errors include incorrect orientation of the unit, failure to secure the mounting bracket properly, and neglecting to bleed air from the system after installation.

Compatibility and accessories

The ELIZ ELÍZ EURO 120 X is compatible with standard plumbing systems using 1/2 inch threaded fittings. It can be integrated into domestic hot water circuits, central heating systems and small commercial applications. Additional components such as expansion vessels, pressure regulators or temperature sensors may be required depending on the system configuration. No specific accessories are included with the unit, but the mounting bracket and pressure relief valve are already fitted.

Technical background for designers

The ELIZ ELÍZ EURO 120 X operates by heating water stored in a 120-litre steel tank lined with zirconium glaze, which provides resistance to corrosion and scaling. The tank is insulated with 33mm thick polyurethane foam, minimising heat loss and reducing standby energy consumption. The internal heating element is controlled by a thermostat settable between 7°C and 75°C, with an ECO mode that limits the maximum temperature to 55°C for improved efficiency. The unit includes two magnesium anodes to protect the tank from internal corrosion, significantly extending its operational life.

Thermal performance is influenced by ambient temperature, insulation quality and the frequency of hot water withdrawals. The design allows for integration with thermostatic mixing valves to prevent scalding in applications where safety is a priority. The unit’s low thermal losses and compact dimensions make it suitable for installations with limited space and high efficiency requirements. The built-in pressure relief valve ensures safe operation under normal and overload conditions, while the frost protection setting prevents damage from freezing temperatures.

Service and operation

Regular maintenance of the ELIZ ELÍZ EURO 120 X includes inspecting the anodes for signs of depletion and replacing them as necessary. While no specific service intervals are provided in the technical data, it is advisable to perform visual inspections and test the pressure relief valve annually. The ECO mode should be activated in installations where energy efficiency is a priority. During operation, ensure the unit is not subjected to excessive pressure or temperature fluctuations, which could affect its longevity.

Key checkpoints include verifying the correct operation of the thermostat, ensuring the electrical connections remain secure, and confirming that the pressure relief valve functions correctly. If the unit is installed in a location prone to cold temperatures, activate the frost protection setting to prevent damage from freezing. The unit’s 5-year warranty on the tank and 2-year warranty on the overall unit reflect the expected service life under normal operating conditions.

Frequently asked questions

Can the ELIZ ELÍZ EURO 120 X be installed in a utility room with moderate humidity?
Yes, the unit is rated for dry indoor environments with a protection class of IP24. It is not suitable for high-humidity areas such as bathrooms or external locations.

Is the ECO mode sufficient for reducing energy consumption in a small household?
Yes, the ECO mode limits the maximum temperature to 55°C, reducing both thermal losses and electricity usage, making it suitable for energy-efficient households.

Can the unit be connected to a pressurised water supply?
Yes, the unit supports a maximum pressure of 6 bar, making it compatible with most domestic and small commercial pressurised water systems.

What happens if the thermostat fails?
The unit includes a thermal cut-out as part of its six-stage safety system, which will automatically disconnect the power to the heating element in case of overheating or malfunction.
