ELÍZ EURO 150 T2 | ELZ_3319 | 150 L | Wall-Mounted Combined Water Heater

Product detailed description

The ELÍZ EURO 150 T2 is a wall-mounted water heater designed for residential and small commercial applications where space is limited and vertical installation is preferred. It is commonly used in apartments, single-family homes, and compact properties where a vertical layout allows for efficient use of wall space. The unit integrates two heat exchangers and an electric heating element, enabling simultaneous or sequential heating via different sources such as a boiler and solar system. The installation involves securing the unit to a wall, connecting the heating circuits and water supply, and ensuring correct electrical and hydraulic integration.

Typical applications include systems where multiple heating sources are available and where the installer must manage the coordination of thermal inputs with domestic hot water demand. The unit is suitable for systems with a primary heating source and a secondary or auxiliary system, such as solar thermal or heat pump integration. The installer must ensure that the hydraulic and electrical connections align with the system's design and that the unit is mounted securely to support its weight and operational stresses.

The technical parameters of the ELÍZ EURO 150 T2 are essential for correct system sizing and integration. The 2000 W electric heating element is suitable for auxiliary heating when primary sources are unavailable. The two heat exchangers have different surface areas and thermal outputs, allowing for flexible system design. The 1/2 inch water inlet and 3/4 inch pipe connections must be matched with corresponding fittings in the installation. The IP 24 rating ensures basic protection against water and dust, but the unit is not suitable for outdoor use. The 6 bar maximum pressure must be considered when connecting to pressurised systems.

Installation and connection

Installation begins with securing the unit to a wall using the provided bracket. The 460 x 1415 mm dimensions require a stable mounting surface capable of supporting the 56.5 kg weight. The water inlet is located at the bottom and uses a 1/2 inch connection. The heating circuits are connected via 3/4 inch ports on the left side. The electric supply must be 230 V with a 10 A circuit breaker and a separate earth connection. The installer should verify that the wall is structurally sound and that the mounting bracket is correctly positioned to avoid stress on the tank. Common mistakes include incorrect orientation of the heating circuits, improper sealing of connections, and failure to check the pressure relief valve function before commissioning.

Compatibility and accessories

The ELÍZ EURO 150 T2 is compatible with a range of heating systems, including gas and oil boilers, heat pumps, and solar thermal collectors. The two heat exchangers allow for simultaneous or sequential operation, depending on the system configuration. The unit includes a pressure relief valve and a safety thermostat, but additional components such as expansion vessels or circulation pumps may be required for larger systems. The installer must ensure that the primary and secondary heating sources are correctly sized to match the unit's thermal capacity. No additional accessories are included with the unit, so any supplementary components must be ordered separately.

Technical background for designers

The ELÍZ EURO 150 T2 operates by transferring heat from two external sources via separate heat exchangers to the water in the tank. The tank is constructed from high-quality steel with a zirconium enamel coating to resist corrosion. The heat exchangers are also made from steel and are designed to handle different thermal inputs. The 32 mm thick polyurethane insulation without CFC ensures minimal heat loss and contributes to the unit's efficiency. The system's performance is influenced by the thermal properties of the heat sources, the flow rates of the heating circuits, and the ambient temperature of the installation space. The two anodes provide additional protection against internal corrosion, extending the service life of the tank.

Service and operation

Regular maintenance includes checking the function of the pressure relief valve, inspecting the anodes for signs of depletion, and verifying the integrity of the electrical connections. The thermostat allows for temperature adjustment between 7 and 75°C, and the built-in indicator provides a visual confirmation of the heating status. The safety thermostat prevents overheating and must be tested periodically. The unit does not require scheduled service intervals, but any unusual noise, leaks, or performance issues should be investigated by a qualified technician. The 5-year warranty on the tank and 2-year warranty on the overall unit reflect the expected durability under normal operating conditions.

Frequently asked questions

Can the ELÍZ EURO 150 T2 be connected to a solar thermal system?
Yes, the unit has two heat exchangers that can be connected to different media, including solar thermal collectors. The installer must ensure that the flow rates and temperatures are compatible with the unit's specifications.

Is the electric heating element sufficient for rapid heating?
The 2000 W electric heating element can raise the temperature of water from 12 to 65°C in 4.7 hours. This is suitable for auxiliary heating but may not be sufficient for high-demand applications without a primary heat source.

Can the unit be installed in a basement or utility room?
Yes, the unit is suitable for indoor installation in spaces with stable temperatures and proper ventilation. The IP 24 rating provides basic protection against water and dust, but it is not suitable for outdoor use.

How is the temperature controlled during operation?
The temperature is controlled via a thermostat on the control panel, which allows adjustment between 7 and 75°C. The built-in indicator confirms when the heating element is active.
