WIGELL Floor Heating Manifold, 11 circuits, brass + automatic air vent

Product detailed description

The underfloor heating manifold is the main component for evenly distributing heat in underfloor heating systems. Manifold variants include different numbers of circuits, usually from 2 to 18, and are compatible with underfloor heating pipes with diameters of 16–20 mm.

Wigell manifolds can be mounted directly on the wall or, using the supplied brackets, into a manifold cabinet. The mounting position is arbitrary. Using compression fittings, you can connect PeX-AL-PeX or Pe-rt pipes to this manifold.

Product parameters

• Permissible liquid temperatures: -10 °C to 120 °C
• Max. working pressure: 4 - 6 bar
• Max. test pressure: 10 bar
• Measuring range: 0-5 l/min
• Flow rate: 1.12 m³/h
• Inlet and outlet connection: 1"
• Flow meters: dual-adjustment, lockable

Advantages of Wigell manifolds

• Every manifold undergoes a pressure test, which guarantees its reliability and long service life.
• You can choose a manual or automatic air vent.
• The cabinet size is precisely determined for the given number of circuits and fits perfectly.
• Control valves can be chosen in two variants with thermometer preparation, either angled or straight.
• The manifold is fitted with control valves, flow meters and air vents.

This manifold assembly consists of

Heating water body:

• flow meters terminated with a nipple and PEX 3/4 x 16 coupling
• air vent and drain unit with automatic air vent (a key-operated air vent can also be used)

Return water body:

• thermostatic valves M30 x 1.5 - option to fit thermal actuators
• nipples fitted with PEX 3/4 x 16 couplings
• air vent and drain unit with automatic air vent

Flow meter:

Used to set the flow rate of the heating water in l/min and thereby to balance the pressure differences of individual heating circuits. Depending on the direction you turn the lower part of the flow meter, you decrease or increase the flow of heating water, or shut it off completely. On the transparent part of the flow meter, the water level shows the water flow in l/min. Max. operating pressure is 1 MPa.

Thermostatic valve:

Thermostatic valve inserts with manual heads are used to shut off individual heating circuits. These manual heads cannot be used to regulate individual branches. The manual heads can be removed and replaced with electric actuators.

Air vent and drain unit:

Used to vent the heating system. The air vent valve of this unit is automatic, and it can be replaced with a key-operated air vent valve.

What else should you buy for the air vent?

Additional accessories are required for proper installation. Below, choose the connection components that are fully compatible with this manifold:

• Recessed and surface-mounted cabinets
• Mixing sets (WILO pump + ESBE valve) - for variants without a built-in pump
• Ball valves for connection without a circulation pump
• Compression fittings

For pipe laying, we also recommend purchasing:

• Underfloor heating pipes
• Underfloor heating foils
• Clips for fastening floor pipes
• Staplers and pipe uncoilers
• Expansion tapes for the wall

Packaging and delivery method

We will deliver the product to you via standard parcel shipping, and it will be packaged so as to prevent damage during transport. The exact method of packaging depends on the number of pieces ordered and other order items. A standalone manifold is most often packaged in a cardboard box and stretch film.
