Residential measuring set - without cabinet - heating Kv 2,75; without meter and water meter IVAR.EQM 13B

Product detailed description

This modular measuring set is commonly used in residential buildings with central heating systems. It is typically installed in individual units to measure heat and water consumption accurately. The system supports both radiator and underfloor heating configurations, requiring careful balancing and system flushing before operation. The set is designed for integration with central heating distribution systems and includes components for measuring both hot and cold water consumption.

Installers should be aware of the importance of system preparation, including thorough flushing and treatment with recommended additives. The set is suitable for use in multi-apartment buildings and single-family homes where individual unit metering is required. The modular design allows for flexible installation depending on the specific system layout and requirements.

Technical parameters

The PN 10 pressure rating indicates the maximum allowable operating pressure of the system components, ensuring compatibility with standard domestic heating systems. The material specification (brass CB753S) ensures corrosion resistance and durability in hot water environments. These parameters are essential for proper sizing and selection to match the system's hydraulic and thermal requirements.

Installation and connection

Installation requires careful planning to ensure correct orientation and alignment of all components. The set includes external thread connections of 3/4 inch for all inlet and outlet ports. Before installation, verify that all components are clean and free from manufacturing debris. Common installation errors include incorrect orientation of the heat meter and failure to flush the system before commissioning. Ensure that all valves are fully open during initial system filling to prevent air trapping and flow restrictions.

Compatibility and accessories

This measuring set is designed to be used with central heating systems that require individual unit metering. It is compatible with standard heating circuits and can be integrated with radiators or underfloor heating systems. Additional components such as a cabinet or water meter are not included and must be ordered separately if required. The set is intended for use with IVAR.EQUIMETER systems and should be combined with compatible heat meters and water meters for full functionality.

Technical background for designers

The measuring set operates by measuring the flow and temperature difference between supply and return lines to calculate heat consumption. The brass CB753S material provides good thermal conductivity and resistance to corrosion in hot water environments. The system's efficiency depends on correct balancing of the flow and accurate temperature measurement. Long-term performance is influenced by the quality of system maintenance and the presence of contaminants in the water. The modular design allows for easy integration into existing systems and facilitates future upgrades or replacements.

Service and operation

Regular inspection of the system is recommended to ensure all components are functioning correctly. Check for leaks at all connections and verify that the heat meter is operating within its specified range. The system should be flushed periodically to remove any accumulated debris that could affect measurement accuracy. No specific service intervals are provided in the technical documentation, but maintenance should be carried out in accordance with the manufacturer's recommendations.
