ELÍZ EURO 150 S

Product detailed description

Electric water heaters like the ELÍZ EURO 150 S are commonly used in residential and commercial buildings where a reliable and rapid supply of hot water is required. Installers often encounter these units in domestic hot water systems, especially in applications where space is limited but high capacity is needed. The model is suitable for integration into central heating systems or standalone hot water installations. It is particularly useful in multi-user environments such as hotels, hostels, and large households where consistent water temperatures and fast recovery times are essential.

When installing the ELÍZ EURO 150 S, it is important to consider the system’s hydraulic and electrical requirements. The unit is designed for floor-standing operation and requires a dedicated electrical circuit due to its 3kW power draw. The heater is intended for use in dry, indoor environments and must be installed in accordance with local electrical and plumbing codes. The presence of a circulation port allows for integration with circulation pumps to maintain hot water availability in larger pipe runs.

The technical parameters of the ELÍZ EURO 150 S are essential for proper sizing and system compatibility. The 3kW heating element ensures rapid heating, while the IP24 rating indicates protection against solid objects and splashing water. The 6 bar maximum pressure rating is suitable for standard domestic water systems. The 3/4 inch water connection is a common size for domestic plumbing, and the 16A current draw must be accommodated in the electrical design. The 3.1-hour heating time from 12°C to 65°C is typical for a 150L tank with this power rating.

Installation and connection

Installation of the ELÍZ EURO 150 S begins with positioning the unit on a stable, level surface. The heater must be connected to a 230V supply with a 16A circuit breaker. The water inlet and outlet are both 3/4 inch threaded connections, and a non-return valve is included as part of the safety system. The circulation port is located in the central section of the tank and is used to connect a circulation pump if required.

Before energising the unit, the installer should verify that the electrical connections are secure and that the tank is properly grounded. The pressure relief valve must be connected to a safe discharge point to prevent overpressure. A common mistake during installation is neglecting to check the condition of the anodes, which should be inspected and replaced if necessary to maintain corrosion protection. The thermostat should be set to a safe operating temperature range (10–75°C) to prevent scalding and energy waste.

Compatibility and accessories

The ELÍZ EURO 150 S is compatible with standard domestic water systems and can be integrated with circulation pumps, thermostatic mixing valves, and expansion vessels. It is important to ensure that the electrical supply can handle the 3kW load and that the installation includes a suitable circuit breaker. No additional accessories are required for basic operation, but a circulation pump may be needed for systems with long pipe runs. The unit is not compatible with gas or solar heating systems and is designed for standalone electrical operation.

Technical background for designers

The ELÍZ EURO 150 S operates by heating water stored in a 150L steel tank using a 3kW electric heating element. The tank is internally coated with a zirconium-based enamel to prevent corrosion and extend the tank’s lifespan. The dual anode protection system uses two magnesium alloy rods to further reduce the effects of corrosion. The heater is designed for use in standard domestic water pressure conditions (up to 6 bar) and is equipped with a thermostat for temperature control. The unit’s thermal losses are relatively low at 1.11 kWh per 24 hours, making it suitable for systems where energy efficiency is a priority.

The heater is intended for integration into electrical systems with a 230V supply and must be installed in accordance with local electrical regulations. The IP24 rating means it is suitable for dry indoor environments but not for outdoor use. The unit’s free-standing design allows for flexible placement, but it must be installed in a location with adequate ventilation and access for maintenance. The heater’s operating principle is based on thermal conduction and convection, with the heating element located at the bottom of the tank to ensure even heat distribution.

Service and operation

Regular maintenance of the ELÍZ EURO 150 S includes checking the condition of the anodes and ensuring that the tank is free from sediment buildup. The anodes should be inspected and replaced if they show signs of significant corrosion. The pressure relief valve should also be tested periodically to ensure it functions correctly. The thermostat should be checked to confirm that it maintains the desired temperature range and that the heating element is operating efficiently.

During operation, the unit should be monitored for unusual noises, odours, or changes in water temperature. If the heater fails to heat water or shows signs of overheating, the thermal fuse should be checked. The unit is designed for long-term use, with a 5-year warranty on the tank and a 2-year warranty on the overall product. If the unit is not used for extended periods, it should be drained and flushed to prevent stagnation and bacterial growth.

Frequently asked questions

Can the ELÍZ EURO 150 S be used with a circulation pump?
Yes, the unit has a dedicated circulation port for connecting a circulation pump. This allows for continuous hot water availability in systems with long pipe runs.

Is the ELÍZ EURO 150 S suitable for outdoor installation?
No, the unit has an IP24 rating and is intended for dry indoor environments only. It should not be installed in areas exposed to rain or high humidity.

How often should the anodes be replaced?
The anodes should be inspected and replaced if they show significant corrosion. The frequency depends on water quality but is typically every 2–5 years.

Can the temperature be adjusted?
Yes, the unit includes a thermostat that allows the temperature to be set between 10°C and 75°C. This provides flexibility for different applications and energy-saving settings.
