Sunex Heating Circuit Manifold – Efficient Heat Distribution for Your Heating System
Product Overview
The Sunex heating circuit manifold is specifically designed for central heating systems with radiators, underfloor heating, and mixed systems. It enables reliable distribution of heating water to two or three independent circuits, offering flexible application options in residential and commercial buildings.
Available in versions with 2 circuits DN20, 2 circuits DN25, 3 circuits DN20, and 3 circuits DN25, as well as a version with external thread (AG) for easy connection options. The robust construction and high-quality EPP insulation ensure long-lasting performance and minimal heat loss.
Areas of Application
Ideal for new constructions and renovations: Whether underfloor heating or radiators, the manifold adapts to your system and optimizes heat distribution. In mixed systems with different flow temperatures, it excels with precise controllability.
In commercial properties such as offices, practices, and workshops, the Sunex heating circuit manifold also ensures even comfort. Thanks to the variety of versions, it can be adapted to individual performance requirements.
Construction and Materials
The main body of the manifold is made of high-quality steel, which operates reliably even at high temperatures and pressures. The nuts are made of brass and ensure a corrosion-resistant connection.
A 30 mm thick EPP insulation reduces heat losses and improves the efficiency of the system. The M8 mounting allows for easy and secure wall installation without additional brackets.
Technology
Maximum operating temperature: 110 °C | Maximum operating pressure: 6 bar. The output ranges from 29 kW (ΔT=20 K, 2 circuits DN20) to 54 kW (ΔT=20 K, 2-/3-circuit DN25).
Maximum flow rates: 1.2 m³/h for DN20 and 2.3 m³/h for DN25. Dimensions vary depending on the version between 193/137/552 mm and 193/140/862 mm (H/D/W), with a weight between 5.7 and 8.9 kg.
Installation and connection
Thanks to clear markings on the boiler and heating circuit sides, connections are made quickly and without errors. The boiler side is available with male thread 1" or male thread 5/4", and the heating circuit side optionally with female thread 1", female thread 6/4" or male thread 1".
The included mounting hardware enables straightforward wall mounting. Easy access to all connections facilitates maintenance and cleaning work.
Benefits at a glance
The Sunex heating circuit manifold combines a robust steel construction, corrosion-resistant brass nuts and effective EPP insulation. It impresses with high performance, easy installation and flexible connection options.
Perfectly matched to modern heating systems, it provides reliable heat distribution, reduces energy losses and increases living comfort in any building.
