Residential measuring set - without cabinet - heating Kv 2,75; without meter and water meter IVAR.EQM 23B

Product detailed description

Residential measuring sets are essential components in multi-unit heating systems where individual consumption tracking is required. These systems are typically found in apartment blocks, office buildings and commercial properties with central heating distribution. The IVAR.EQM 23b set provides the necessary components for accurate heat and water measurement while maintaining system balance and efficiency. Installers working on these systems must ensure proper integration with existing piping and control systems to maintain accurate readings and efficient operation.

The installation involves connecting the measuring set to the central heating distribution system and configuring the control components to match the building's specific requirements. The set is designed for use with central heating systems that require individual unit metering and balancing. The components must be installed according to the manufacturer's specifications to ensure accurate measurements and long-term reliability.

Technical parameters

Installation and connection

The IVAR.EQM 23b set requires external pipe threads of 3/4 inch for all connections. The installation procedure involves mounting the base plate, connecting the three-way mixing valve, heat meter and balancing valves, and ensuring all components are properly aligned. The system must be flushed according to the manufacturer's instructions before commissioning, particularly when combining floor heating and radiator systems. Common installation mistakes include incorrect valve orientation, improper sealing of connections and failure to follow the flushing procedure, which can lead to inaccurate readings and system inefficiencies.

Installers should verify that all components are correctly connected and that the system is properly balanced. The set includes eight ball valves for inlet and outlet connections, two shut-off valves for system balancing, and a filter to prevent debris from entering the system. The installation must be checked for leaks and proper operation of all valves before the system is put into service.

Compatibility and accessories

The IVAR.EQM 23b set is compatible with central heating systems that require individual unit metering. It includes all necessary components for system operation, including the heat meter, balancing valves and mixing valve. Additional components such as cabinets or water meters need to be ordered separately. The set is designed for use with the IVAR.WFM (MEGATRON 5) heat meter and the IVAR.MT05RU thermostatic mixing valve. The system requires a central heating distribution system with appropriate piping and control components for full functionality.

Technical background for designers

The IVAR.EQM 23b set operates by measuring heat consumption through the integrated heat meter and balancing water flow using the thermostatic mixing valve and balancing valves. The brass CB753S material provides corrosion resistance and durability in heating environments. The PN 10 pressure rating ensures the system can handle typical heating system pressures. The system's efficiency is influenced by proper installation, regular maintenance and the use of the recommended GEL.LONG LIFE 100 treatment to prevent system contamination.

The design of the set allows for accurate heat distribution and consumption tracking in multi-unit buildings. The thermostatic mixing valve maintains a consistent supply temperature, while the balancing valves ensure even heat distribution. The system's performance is also affected by the quality of the installation and the condition of the central heating system.

Service and operation

Regular maintenance of the IVAR.EQM 23b set includes checking for leaks, verifying the operation of all valves and ensuring the system is free from debris. The manufacturer recommends flushing the system according to the instructions before commissioning and using the GEL.LONG LIFE 100 treatment to maintain system cleanliness. No specific service intervals are provided in the technical documentation, but regular inspections are recommended to ensure accurate measurements and system efficiency.

Frequently asked questions

Can the IVAR.EQM 23b set be used with floor heating systems?
Yes, the set is compatible with floor heating systems. However, the system must be flushed according to the manufacturer's instructions before commissioning to ensure proper operation.

Is the thermostatic mixing valve adjustable?
The thermostatic mixing valve has a temperature range of +36 °C to +50 °C and is designed to maintain a consistent supply temperature for the system.

What is the maximum operating temperature for the set?
The set is rated for an operating temperature of up to +90 °C, making it suitable for typical central heating applications.

Does the set include a water meter?
No, the set does not include a water meter. A separate water meter must be ordered and installed for complete system measurement.
