Brass Manifold, 4-way, for Underfloor Heating

Product detailed description

Brass manifold for underfloor heating, 4-way, 1" connection.

The manifold is the heart of the entire underfloor (or radiator) heating system - it distributes heating water from a single source (boiler, circulation pump) to the individual circuits, while also allowing each circuit to be regulated, vented and, if necessary, completely shut off separately without affecting the rest of the system. This means that, for example, when repairing one room you can shut off just its circuit while the rest of the house keeps heating.

What makes this manifold stand out

• Complete set ready for installation - shut-off valves, regulating fittings with flow meters, an automatic air vent valve and a drain valve are already included in the delivery; nothing else needs to be purchased apart from the compression fitting for your specific pipe.
• Precise regulation of each circuit separately - the flow meters on the top bar let you set the flow in each loop individually, so you can achieve even heating even with circuits of different lengths.
• Automatic venting - the built-in air vent valve continuously removes air that would otherwise cause bubbling and reduced output.
• Durable brass construction - Press-Messing Ms 58 fitting, nickel-plated, suitable for many years of operation.

Step-by-step installation

1. Mount the manifold in a cabinet using the supplied brackets (the cabinet is purchased separately, see recommended accessories below) or directly on the wall on a sufficiently solid surface.
2. Connect the flow and return from the heat source to the manifold's inlet and outlet (1").
3. Screw the compression fitting matching your pipe diameter onto each branch and connect the individual underfloor heating circuits.
4. Before starting up, thoroughly fill and vent the system - leave the automatic air vent valve slightly open until only water, with no air, starts to flow out of it.
5. Regulate the flow on each circuit using the flow meters so that it matches the length and load of the given loop (longer or more heavily loaded circuits need a higher flow rate).

Recommended accessories

• Pipe: PEX-AL-PEX 16 x 2

Frequently Asked Questions

• How do I choose the number of circuits? The number of circuits corresponds to the number of separate underfloor heating loops you want to connect to the manifold - typically one circuit per room, or more circuits for larger rooms.
• What else do I need for installation? A compression fitting to connect the pipe to the manifold (according to your pipe diameter) and a suitable cabinet to house it.
• Can it also be used for cooling? Yes, the manifold is designed for both heating and cooling systems using water or water mixtures with a standard anti-corrosion antifreeze additive.
• What if the exact number of circuits doesn't suit me? Manifolds in this range are available from 2 to 12 circuits, so you can choose exactly according to the needs of your project.
