ELIZ EURO 150 | ELZ_3307 | 150 L Electric Vertical Water Heater

Product detailed description

Electric water heaters of the vertical type are commonly used in residential and commercial buildings where space is limited and a compact solution is required. Installers and service technicians often encounter these units in kitchens, bathrooms, and utility rooms. The ELIZ EURO 150 is designed for integration into standard domestic hot water systems, where it provides a reliable and efficient means of heating water for domestic use. It is particularly suited for installations where wall mounting is preferred and where the system requires a compact footprint with sufficient storage capacity for multiple outlets.

When selecting a water heater for a specific installation, the installer must consider the number of simultaneous hot water outlets, the required flow rate, and the system's hydraulic and electrical compatibility. The ELIZ EURO 150 is intended for use in systems with standard domestic water pressure and electrical supply. It is not suitable for high-flow applications such as large kitchens or commercial laundries.

The technical parameters of the ELIZ EURO 150 are essential for determining its suitability for a specific installation. The 150-litre capacity is appropriate for households with up to five users or for systems with multiple outlets. The 3000W power rating ensures a relatively fast heating time of 3.1 hours from 12 to 65°C. The 230V supply and 16A fuse rating are standard for domestic electrical systems in Europe. The IP24 rating indicates that the unit is protected against solid objects larger than 1 mm and splashing water, making it suitable for indoor use. The 1/2 inch water connection is compatible with standard domestic plumbing systems.

Installation and connection

Installation of the ELIZ EURO 150 requires secure wall mounting using the provided bracket. The unit must be installed in a location with good ventilation and access to the electrical supply. The water inlet and outlet are both 1/2 inch threaded connections, which must be checked for compatibility with the existing plumbing. A pressure relief valve and check valve are included as part of the unit, but the installer should verify that the system's pressure does not exceed 6 bar. Common installation mistakes include incorrect wall mounting, which can lead to instability, and failure to secure the electrical connections properly, which can cause overheating or electrical faults.

Before commissioning, the installer should check the water pressure, electrical connections, and the integrity of the insulation. The thermostat should be set to a safe minimum temperature to prevent freezing in cold environments. The ECO mode should be tested to ensure that it reduces energy consumption without compromising performance. The unit must be grounded correctly, and the electrical circuit must be protected by a 16A fuse or circuit breaker.

Compatibility and accessories

The ELIZ EURO 150 is compatible with standard domestic plumbing systems and electrical circuits. It can be used in conjunction with thermostatic mixing valves to regulate the temperature of the water supplied to taps and showers. No additional accessories are required for basic operation, as the unit includes a pressure relief valve and check valve. However, in larger systems or where additional safety is required, the installer may consider adding an expansion vessel or a separate temperature and pressure relief valve.

Technical background for designers

The ELIZ EURO 150 operates by heating water stored in a steel tank using an electric heating element. The tank is coated with a zirconium-based glaze to protect against corrosion, and the insulation is made of polyurethane with a thickness of 43 mm. This insulation reduces heat loss to 1.11 kWh per 24 hours, contributing to lower energy consumption. The thermostat allows the user to set the desired temperature between 7 and 75°C, with an ECO mode that optimizes energy use by heating the water to 55°C. The unit includes a thermal cut-out to prevent overheating and a frost protection setting to prevent damage in cold conditions.

When integrating the ELIZ EURO 150 into a system, the designer must consider the electrical load and the hydraulic characteristics of the installation. The unit is not suitable for use with solar thermal systems or other heat sources that require a different control strategy. The service life of the unit is influenced by the quality of the water supply, the frequency of use, and the maintenance of the anodes. The two magnesium anodes included in the unit provide sacrificial protection to the tank, extending its lifespan and reducing the risk of internal corrosion.

Service and operation

Regular maintenance of the ELIZ EURO 150 includes checking the anodes for signs of wear and replacing them if necessary. The anodes are designed to corrode in place of the tank and should be inspected every 2–3 years. The insulation should also be checked for damage, and the electrical connections should be verified for tightness and integrity. The pressure relief valve should be tested periodically to ensure that it functions correctly in the event of overpressure.

During operation, the user should monitor the temperature setting and ensure that it is appropriate for the intended use. The ECO mode should be used in situations where energy efficiency is a priority. The unit should be turned off during periods of non-use to reduce energy consumption. If the unit fails to heat water or shows signs of overheating, the thermal cut-out should be checked and reset if necessary. In the event of a fault, the unit should be disconnected from the power supply and inspected by a qualified technician.

Frequently asked questions

Can the ELIZ EURO 150 be used in a system with a solar water heater?
No, the ELIZ EURO 150 is not designed for integration with solar thermal systems. It is intended for use with a standard electrical supply and cannot be used in hybrid systems without additional control equipment.

Is the ECO mode sufficient for energy savings in cold climates?
Yes, the ECO mode reduces energy consumption by heating the water to 55°C, which is sufficient for most domestic uses. However, in very cold climates, the frost protection setting should be enabled to prevent freezing.

Can the anodes be replaced without draining the tank?
No, the anodes must be accessed from the top of the tank and require the unit to be drained before replacement. This should be done by a qualified technician to avoid damage to the tank or electrical components.

What is the maximum number of simultaneous outlets the ELIZ EURO 150 can support?
The unit is suitable for up to five users or multiple outlets in a typical household. For larger systems or commercial applications, a higher-capacity unit should be selected.
