ELÍZ EURO 150 TR

Product detailed description

Combined water heaters like the ELÍZ EURO 150 TR are commonly used in residential and small commercial applications where both hot water supply and space heating are required. Installers working on central heating systems often integrate such units into systems that include gas or oil boilers, heat pumps, or other thermal sources. The vertical orientation allows for efficient use of space in utility rooms, boiler houses, or technical areas. The unit is suitable for installations where the demand for hot water is moderate, and where supplementary heating is needed for underfloor or radiators. The compact design and wall-mounting capability make it ideal for buildings with limited floor space.

When selecting a combined water heater, the installer must consider the thermal load, water consumption patterns, and the compatibility with existing heating systems. The ELÍZ EURO 150 TR is designed to interface with a range of external heat sources, making it adaptable to different system configurations. The unit’s integration with the heating system requires careful planning of pipe routing, insulation, and control logic to ensure balanced performance between hot water and heating outputs.

The technical parameters listed define the operational limits and capabilities of the unit. The 2000 W electrical input and 230 V supply voltage indicate the power requirements for the internal electric heating element. The maximum pressure rating of 6 bar ensures compatibility with standard domestic water systems. The 1/2 inch water inlet and 3/4 inch pipe connection for the heat exchanger are critical for correct sizing of fittings and pipe diameters during installation. The 4.7-hour heating time from 12°C to 65°C is a key factor in determining whether the unit meets the required recovery rate for the intended application.

Installation and connection

The ELÍZ EURO 150 TR is designed for vertical wall mounting using the provided bracket. Before installation, ensure the wall surface is strong enough to support the unit’s weight of 52 kg. The 1/2 inch water inlet and 3/4 inch heat exchanger connection require matching threaded fittings. Secure all connections with appropriate sealing materials such as PTFE tape or compression fittings. The unit includes a safety cut-off and a pressure relief valve; these should be checked for correct positioning and accessibility after installation. Incorrect mounting height or misaligned pipe connections can lead to water leakage or inefficient heat transfer.

During installation, verify that the electrical supply matches the unit’s specifications (230 V, 10 A, IP 24 rating). The unit must be connected via a dedicated circuit with a suitable fuse or circuit breaker. Avoid placing the unit in direct sunlight or near heat sources that could affect its thermal insulation. After installation, perform a pressure test on the water side and a visual inspection of all electrical and mechanical connections. Common errors include incorrect orientation of the heat exchanger ports and failure to align the mounting bracket properly.

Compatibility and accessories

The ELÍZ EURO 150 TR is compatible with various external heat sources such as gas or oil boilers and heat pumps. For optimal performance, the heat exchanger must be connected to a thermal circuit with a minimum flow rate of 0.89 m² and a nominal power of 26 kW. The unit does not include additional components such as expansion vessels or circulation pumps; these must be sourced separately depending on the system configuration. The included safety cut-off and pressure relief valve are essential for system integrity and should not be bypassed or modified.

Technical background for designers

The ELÍZ EURO 150 TR operates as a pressurized storage heater with a dual function: it provides domestic hot water and transfers heat to a secondary circuit for space heating. The internal tank is constructed from high-grade steel with a zirconium glaze coating, which enhances resistance to corrosion. The heat exchanger is also made of steel and is integrated within the tank to allow simultaneous heating of water and thermal transfer. The 33 mm thick polyurethane insulation with no CFC content minimizes heat loss and supports energy efficiency.

The unit integrates into a heating system through the heat exchanger, which is connected to a separate circuit via the 3/4 inch threaded port. The thermal performance depends on the flow rate and temperature differential between the incoming and outgoing water in the secondary circuit. The presence of two magnesium anodes provides sacrificial protection against internal corrosion, significantly extending the service life of the tank. The ECO mode reduces energy consumption by limiting the maximum water temperature to 55°C, which is sufficient for most domestic uses while minimizing heat loss.

Service and operation

Regular maintenance of the ELÍZ EURO 150 TR includes checking the condition of the anodes and the integrity of the thermal insulation. The anodes should be inspected and replaced if necessary after five years, as specified in the warranty. The pressure relief valve and safety cut-off should also be tested periodically to ensure they function correctly. During operation, the thermostat allows temperature adjustment between 7°C and 75°C, with the ECO mode setting the default to 55°C. The frost protection feature prevents damage in unheated environments by maintaining a minimum temperature.

Installers should ensure that the unit is accessible for maintenance and that the control panel is clearly visible. The indicator light on the power switch provides a visual confirmation of the heating status. If the unit is not in use for extended periods, it should be drained and flushed to prevent sediment buildup. The warranty covers the tank for five years and the overall product for two years, provided the unit is installed and maintained according to the manufacturer’s guidelines.

Frequently asked questions

Can the ELÍZ EURO 150 TR be connected to a condensing boiler?
Yes, the unit can be connected to a condensing boiler via the heat exchanger port. Ensure the boiler’s output matches the heat exchanger’s capacity of 26 kW.

Is the ECO mode sufficient for regular domestic use?
Yes, the ECO mode sets the water temperature to 55°C, which is adequate for most domestic applications while reducing energy consumption and heat loss.

How often should the anodes be replaced?
According to the manufacturer’s guidelines, the anodes should be inspected and replaced if necessary after five years to maintain the tank’s corrosion protection.

What should be done if the pressure relief valve activates frequently?
If the pressure relief valve activates frequently, check the water pressure in the system and ensure the expansion vessel is correctly sized and functioning. High pressure or overheating could indicate a fault in the system.
