ELÍZ EURO 500 D1

Product detailed description

The ELÍZ EURO 500 D1 is a freestanding water heater commonly used in residential and commercial buildings where heat pumps, solar thermal systems or central heating units are the primary heat sources. It is typically installed in mechanical rooms, basements or utility areas where space allows for a large, stationary unit. The heater is designed for integration into systems requiring a high-capacity thermal storage solution, such as underfloor heating, domestic hot water supply, or combined space and water heating systems. Installers working with heat pump systems or solar thermal installations will find this unit suitable for balancing thermal loads and ensuring continuous hot water supply.

Its 500 L tank and 9 kW electric heating element make it ideal for applications where rapid heating is required. The large surface area of the heat exchanger allows for efficient heat transfer from external sources, such as a heat pump or boiler. The unit supports both electric and external heat inputs, making it a flexible solution for hybrid heating systems. The heater is designed for use in systems with a 400 V power supply and a 3 x 16 A circuit, with an IP21 rating for indoor use.

The 9000 W (3 x 3000 W) power rating and 400 V supply voltage indicate that the heater is suitable for high-demand applications where rapid heating is required. The 3 x 16 A circuit and IP21 rating confirm that it is intended for indoor installation and requires a dedicated electrical circuit. The 8 bar maximum tank pressure and 3/4 inch water connection are standard for domestic and commercial hot water systems. The 3.5-hour heating time from 12 to 65°C is typical for a 500 L tank with a 9 kW heating element, and the 0.071 kWh/24h heat loss is within the expected range for a well-insulated unit.

Installation and connection

Installation of the ELÍZ EURO 500 D1 requires a level, stable floor and sufficient clearance for maintenance and access to electrical and plumbing connections. The unit is freestanding and must be placed on a non-combustible surface. The 3/4 inch water inlet and outlet connections use standard thread types, and the 5/4 inch pipe connection for the heat exchanger should be checked for compatibility with the external heat source. A 3 x 16 A circuit with a 400 V supply is required for the electric heating element, and the IP21 rating means the unit must be installed in a dry, indoor location.

Common installation mistakes include incorrect electrical wiring, failure to secure the unit on a stable base, and neglecting to check the pressure relief valve. The heater includes a built-in pressure relief valve and a safety fuse, but these must be verified during installation. The circulation port in the middle of the tank allows for the connection of a circulation pump, which should be installed according to the system’s hydraulic requirements. The two additional ports for control sensors must be connected to the system’s control panel to enable temperature monitoring and regulation.

Compatibility and accessories

The ELÍZ EURO 500 D1 is compatible with a range of heat sources, including heat pumps, central heating boilers and solar thermal systems. It is designed for use with systems that require a high-capacity thermal storage solution. The heater supports both electric and external heating inputs, making it suitable for hybrid systems. No additional accessories are required for basic operation, but a circulation pump may be needed if the system requires continuous hot water supply. The heater includes a built-in pressure relief valve and a safety fuse, eliminating the need for external components in most installations.

Technical background for designers

The ELÍZ EURO 500 D1 operates by heating water using either the built-in electric heating element or an external heat source connected to the heat exchanger. The heat exchanger has a surface area of 5.06 m² and a thermal capacity of 65 kW, making it suitable for high-output heat sources such as heat pumps. The tank is constructed from high-quality steel and coated with a zirconium-enriched glaze to resist corrosion. The double anode protection system, consisting of two magnesium alloy anodes, further extends the tank’s lifespan by reducing the effects of corrosion.

The heater is designed for integration into systems with a 400 V power supply and a 3 x 16 A circuit. The IP21 rating indicates that it is suitable for indoor use and must be installed in a dry environment. The heater’s thermal losses are low due to the high-density polyurethane insulation with a thickness of 85 mm. The heater supports temperature control via a thermostat with a range of 10 to 75°C, and an ECO mode can be selected to reduce energy consumption. The heater’s 5-year warranty on the tank and 2-year warranty on the unit reflect the manufacturer’s confidence in the product’s durability and performance.

Service and operation

Maintenance of the ELÍZ EURO 500 D1 includes periodic inspection of the pressure relief valve, anode rods and electrical connections. The heater includes a built-in safety fuse and thermostat, which should be checked during routine maintenance. The heater’s low thermal losses reduce the need for frequent operation of the heating element, which in turn reduces maintenance requirements. The heater’s ECO mode can be used to further reduce energy consumption and extend the lifespan of the heating element. No specific service intervals are provided in the technical data, but regular inspection is recommended to ensure optimal performance.

Frequently asked questions

Can the ELÍZ EURO 500 D1 be connected to a heat pump system?
Yes, the heater is designed for integration with heat pump systems. The heat exchanger allows for efficient heat transfer from the heat pump, and the heater supports both electric and external heating inputs.

Is the heater suitable for use with solar thermal systems?
Yes, the heater is compatible with solar thermal systems. The heat exchanger can be connected to a solar collector, and the heater can be controlled via the system’s thermostat and control panel.

Can the heater be used for both space heating and domestic hot water?
Yes, the heater can be used in systems that require both space heating and domestic hot water. The circulation port allows for the connection of a circulation pump, and the heat exchanger can be used to transfer heat to a space heating system.

What is the maximum pressure the tank can handle?
The tank is rated for a maximum pressure of 8 bar. This is suitable for most domestic and commercial hot water systems, but the pressure should be monitored to prevent over-pressurisation.
