Circulation pump group Comap MeiFlow Combi UK/UK (WILO YONOS PARA RS 15/6) for heating systems

The Comap MeiFlow Combi UK/UK pump group with WILO YONOS PARA RS 15/6 circulation pump is an integrated assembly designed for closed heating and hot-water circulation installations. The unit combines a compact circulation pump with pre-configured hydraulic connections and shut-off valves to simplify mounting in central heating, boiler circuits and domestic hot-water recirculation systems. The product is intended for residential and light commercial applications requiring reliable fluid circulation, pressure maintenance and controlled recirculation.

Advantages

The integrated design reduces installation time by providing ready hydraulic connections and isolation valves in a single modular unit. The WILO YONOS PARA RS 15/6 pump offers variable-speed control and energy-efficient operation appropriate for typical heating circuits. Built-in service points and straightforward pipe interfaces allow easier maintenance and replacement without major system disassembly. The assembly is compatible with common heating system components and supports stable recirculation performance under varying load conditions.

Suitable for

• Domestic central heating systems
• Boiler secondary circuits and buffer tank circulation
• Domestic hot-water recirculation loops
• Light commercial buildings with closed hydronic systems

Key specifications

• Type of pump: electronically commutated variable-speed circulation pump
• Hydraulic connections: pre-assembled compact pump group with isolation valves
• Installation: designed for closed-loop heating and hot-water recirculation
• Control features: speed regulation for matching flow to system demand
• Application temperature range: suitable for typical heating and DHW temperatures
• Material compatibility: suitable for common heating system fluids
• Mounting orientation: inline connection adapted for standard piping layouts

How to use

Mount the pump group into the heating or hot-water circuit using the provided hydraulic connections and ensure correct pipe orientation and secure flange or threaded joints. Follow system design requirements for flow direction and install electrical connections according to the pump manufacturer’s wiring diagram. Commission the pump by verifying system fill, venting air from the circuit, and setting the pump control mode or speed to match the hydraulic resistance of the installation. Monitor for leaks and confirm steady circulation before leaving the system in service.

Usage recommendations

Perform initial commissioning with air venting and system flushing to avoid pump damage. Select pump control settings based on system head loss and expected flow to optimize energy use. Schedule periodic inspection of isolation valves and connections and follow manufacturer guidance for electrical and mechanical maintenance.
