## Long description

Meibes Wartownik typu K with insulation MHK DN25 for up to 70 kW is a compact hydraulic module designed for heating systems that require reliable hydraulic separation and controlled flow. The unit accepts DN25 connections and is suitable for installations with output up to 70 kW. Its insulated body reduces heat loss and helps maintain system efficiency while simplifying mounting in boiler rooms or plant rooms.
Advantages
The insulated design minimizes thermal losses and contributes to stable temperature control across the hydraulic circuit. DN25 connection size offers compatibility with typical residential and light commercial piping layouts. The device supports hydraulic separation and circulation balancing, which reduces interaction between primary and secondary circuits and helps prevent pump short-cycling. Construction and materials are selected to withstand common heating system conditions and to provide consistent performance within the rated power range.
Suitable for
Residential boiler systems with outputs up to 70 kW
Light commercial heating installations requiring DN25 connections
Systems needing hydraulic separation between primary and secondary circuits
Retrofit projects where insulated hydraulic components are preferred
Key specifications
Connection nominal size: DN25
