Boiler module MULTIMIX-C - not mixable - 3/4 "Fx3/4 "M - action IVAR.MUL-C 10 E

Product detailed description

The IVAR MULTIMIX-C boiler module is commonly used in residential and commercial heating systems to regulate and distribute hot water. It is typically installed in boiler rooms, underfloor heating systems, or in systems requiring precise temperature control. The module is designed for use with central heating boilers and is suitable for both new installations and system upgrades. It is important to ensure that the system design accounts for the module’s flow capacity and pressure requirements to maintain optimal performance.

During installation, the module is connected to the boiler and the distribution system using standard pipe connections. The copper piping ensures good thermal conductivity and long-term durability. The module is intended for use with systems operating at up to 120°C and must be integrated into a properly sized hydraulic circuit to avoid flow restrictions or excessive pressure drops.

The operating temperature of +120°C and PN 10 pressure rating are critical for determining the module’s suitability for specific heating systems. The maximum flow rate of 1700 l/h is essential for sizing the hydraulic circuit and ensuring that the boiler can supply sufficient heat to the load. The copper distribution piping is selected for its thermal efficiency and resistance to corrosion, making it ideal for long-term use in heating systems.

Installation and connection

The module is connected using 3/4 inch female to male thread connections (3/4” F x 3/4” M). It is important to verify that the connecting pipes are properly aligned and that the thread connections are sealed with appropriate sealing materials, such as EPDM O-rings. A common mistake during installation is incorrect orientation of the circulation pump or failure to secure the check valve in the correct direction. The module must be installed in a location that allows for easy access to the thermometers and valves for monitoring and maintenance.

Compatibility and accessories

The module is compatible with standard central heating boilers and can be integrated into both open and closed-loop systems. It includes a built-in circulation pump, check valve, two thermometers, and a ball valve for filling and draining. No additional accessories are required for basic operation. The module is not interchangeable with mixable versions of the MULTIMIX-C series and must be selected based on the system’s mixing requirements.

Technical background for designers

The module operates by receiving hot water from the boiler and distributing it to the heating circuits. The copper piping ensures efficient heat transfer and minimises thermal losses. The EPDM O-rings and brass fittings (CW617N) provide a reliable seal and resistance to thermal expansion. The design of the module allows for integration into systems with varying flow rates, but it is important to match the system’s hydraulic requirements to the module’s flow capacity to avoid overloading the pump or causing pressure imbalances.

Service and operation

Regular inspection of the circulation pump and check valve is recommended to ensure continued performance. The ball valve should be used to drain the system during maintenance or seasonal shutdowns. No specific service intervals are provided in the technical data, but it is advisable to follow the manufacturer’s guidelines for pump maintenance and system checks. The thermometers should be monitored regularly to detect any changes in system performance or temperature deviations.

Frequently asked questions

Can the MULTIMIX-C module be used with a condensing boiler?
Yes, the module is suitable for use with condensing boilers provided that the system is designed to accommodate the boiler’s operating parameters and the module’s flow requirements.

Is the module suitable for use in a closed-loop heating system?
Yes, the module can be integrated into closed-loop systems as it includes a circulation pump and check valve to maintain system integrity and prevent backflow.

Can the module be used in a system with multiple heating circuits?
Yes, the module is designed to distribute hot water to multiple circuits, but the system must be sized to ensure that the flow rate and pressure are sufficient for all circuits.

What materials are used for the internal components?
The distribution piping is made of copper, and the fittings are made of brass (CW617N) with EPDM O-rings for sealing and thermal resistance.
