ELÍZ EURO 100 THV

Product detailed description

Indirect water heaters are essential components in central heating systems where space constraints require compact solutions. The ELÍZ EURO 100 THV is designed for installation beneath wall-mounted boilers in residential and commercial buildings. Its vertical orientation and top-mounted connections simplify integration with underfloor boiler units while maintaining access for servicing. The unit provides domestic hot water storage through thermal energy transferred from the boiler circuit via a separate heat exchanger. Installers working on modern heating systems often encounter requirements for compact yet high-capacity storage solutions that can be mounted close to the boiler unit.

This model is particularly suited for installations where boiler space is limited but hot water demand remains high. The top-mounted configuration reduces the need for complex pipe routing compared to side or bottom connection alternatives. The circulation port allows for integration with secondary circuits such as floor heating or towel radiators. The 42.5 kg weight requires stable mounting on a solid floor surface, with proper load-bearing calculations for the installation location.

The 6 bar maximum tank pressure rating indicates the system's ability to handle typical central heating pressures. The 3/4 inch pipe connections align with standard domestic plumbing sizes. The 29 kW heat exchanger capacity determines the rate of water heating based on temperature differential between the boiler circuit and stored water. The 1.03 m² surface area of the coil influences heat transfer efficiency and response time to changing demand patterns.

Installation and connection

Installers should begin by verifying the floor's load-bearing capacity to support the 42.5 kg unit. The vertical dimensions (462 x 1025 x 485 mm) require sufficient clearance for maintenance access and pipe connections. All 3/4 inch threaded connections should be checked for correct orientation and alignment with the boiler unit. A common mistake is misalignment of the circulation port with the required secondary circuit, which can lead to inefficient heat distribution. The drain valve and cleaning flange should be accessible for periodic maintenance. The metal safety valve with check valve must be tested for proper function after installation. Ensure all connections are sealed with appropriate thread sealant according to local plumbing codes.

Compatibility and accessories

This water heater is specifically designed for use with wall-mounted boilers that require underfloor storage solutions. The top-mounted connections facilitate integration with boiler units having matching pipe layouts. For systems requiring additional control functions, an external thermostat can be connected via the dedicated port. The cleaning flange allows for inspection and maintenance of internal components. While no specific alternative models are listed, similar ELIZ water heater models with different dimensions or connection configurations may be suitable for alternative applications.

Technical background for designers

The indirect heating principle relies on thermal conduction through the copper coil heat exchanger. The zirconium-glazed steel tank resists corrosion while maintaining structural integrity. The 33 mm polyurethane insulation minimizes heat loss and reduces energy consumption for maintaining water temperature. The large surface area of the sacrificial anode provides extended protection against internal corrosion. System efficiency depends on proper sizing relative to boiler output and hot water demand patterns. The top-mounted configuration simplifies integration with boiler units but requires careful consideration of heat loss from the exposed upper portion of the tank.

Service and operation

Periodic maintenance should include checking the safety valve function and inspecting the anode rod condition. The cleaning flange allows for visual inspection of internal surfaces. The drain valve enables complete emptying for major servicing. The 5-year warranty on the tank covers manufacturing defects but does not include normal wear of sacrificial anodes or insulation degradation. The 2-year general warranty covers other components. Regular temperature checks using the indicator scale help maintain optimal performance and prevent overheating.

Frequently asked questions

Can the ELÍZ EURO 100 THV be used with condensing boilers?
Yes, the indirect heating system is compatible with condensing boiler technology as long as the temperature parameters match the boiler's operating range.

Is the circulation port suitable for floor heating applications?
The 3/4 inch threaded port can connect to standard floor heating manifolds, provided the flow rate matches the system requirements.

How should the safety valve be tested during installation?
After installation, the metal safety valve with check valve should be manually lifted to verify free movement and proper reseating without leaks.

Can the thermostat be replaced with a different model?
External thermostats can be connected via the dedicated port, but compatibility with the existing control system should be verified before installation.
