ELÍZ EURO 120 TR

Product detailed description

The ELÍZ EURO 120 TR is a vertical storage water heater designed for installation in residential and commercial buildings where a reliable supply of hot water is required for one or more outlets. This unit is typically integrated into central heating systems, either as a standalone solution or in combination with a boiler or heat pump. Installers working on domestic hot water systems will find this model suitable for applications requiring both domestic hot water and space heating support via the built-in heat exchanger. The compact vertical design allows for wall mounting in standard mechanical rooms or utility areas, where space is often limited.

The heater is intended for use with closed-loop heating systems and is compatible with a range of central heating sources. Its modular design supports integration with external thermal energy sources such as solid fuel or gas boilers. The system requires proper hydraulic balancing to ensure efficient operation and to prevent thermal losses. The heater’s internal components are engineered to withstand continuous operation under normal domestic conditions, making it a durable option for long-term use in heating and water supply systems.

Technical parameters

The 2000 W electric heating element ensures rapid temperature rise, while the heat exchanger can be connected to a boiler for secondary heating. The 230 V supply voltage and 10 A current draw are standard for domestic electrical circuits. The IP24 protection rating indicates suitability for dry indoor environments. The 1/2 inch water inlet and 3/4 inch pipe connection allow for flexible integration into existing plumbing systems. The 6 bar maximum tank pressure must be considered during system design to avoid overpressure risks. The 3.8 hour heating time from 12°C to 65°C is relevant for sizing in systems with high demand periods.

Installation and connection

Mounting the ELÍZ EURO 120 TR requires secure wall anchoring due to its 43 kg weight. The unit is equipped with a bracket for vertical installation, and the dimensions (462 x 1170 mm) should be verified against available space. The 1/2 inch water inlet and 3/4 inch pipe connection require standard plumbing fittings. The heat exchanger ports are located on the right side of the unit, while water ports are at the bottom. Installers should ensure all connections are leak-free and that the system pressure does not exceed 6 bar. A safety valve and check valve are included in the package, and these must be installed according to local regulations. Common mistakes include incorrect orientation of the heat exchanger and failure to secure the tank properly, which can lead to vibration or misalignment over time.

Compatibility and accessories

This water heater is compatible with external hot water sources such as boilers or heat pumps that provide thermal energy for the heat exchanger. The electric heating element operates independently, allowing the unit to function even without an external heat source. For optimal performance, the system should be balanced to ensure even heat distribution. No additional accessories are listed in the product description, but the unit includes a bracket for wall mounting and a safety valve with check function. Related products are not specified in the brief.

Technical background for designers

The ELÍZ EURO 120 TR operates using a combination of electric resistance heating and heat exchange from an external source. The steel tank is coated with zirconium glaze to resist corrosion, and the heat exchanger is also made of steel with the same protective coating. The 33 mm thick polyurethane insulation (CFC-free) minimises heat loss and reduces energy consumption. The two magnesium anodes protect the tank from internal corrosion, significantly extending its service life. The system integrates into central heating setups by connecting the heat exchanger to a boiler’s hot water circuit. The efficiency of the unit depends on correct sizing of the heat exchanger, proper insulation, and regular maintenance of the anodes and safety devices.

Service and operation

Periodic maintenance includes checking the condition of the anodes and replacing them when necessary to prevent tank corrosion. The safety valve and pressure relief system should be inspected annually to ensure they operate correctly under pressure. The thermostat allows temperature settings between 7°C and 75°C, with an ECO mode set to 55°C for reduced energy use. The frost protection setting prevents freezing damage in unheated spaces. No specific service intervals are provided in the brief, but regular inspections are recommended to maintain system performance and safety.

Frequently asked questions

Can the ELÍZ EURO 120 TR be connected to a boiler?
Yes, the unit includes a heat exchanger that allows connection to a boiler or other hot water source for secondary heating.

What is the purpose of the ECO mode?
The ECO mode sets the water temperature to 55°C, reducing energy consumption and thermal losses while maintaining sufficient hot water for most applications.

How is the unit protected against corrosion?
The tank and heat exchanger are coated with zirconium glaze, and two magnesium anodes are built in to provide additional internal protection.

Is the thermostat adjustable?
Yes, the thermostat allows manual adjustment of the water temperature between 7°C and 75°C, with a dedicated ECO setting.
