WIGELL Floor Manifold, 15 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.

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

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-regulation with locking option

Advantages of Wigell manifolds

• Each manifold undergoes a pressure test, ensuring 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 a thermometer connection, 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 type coupling
• venting 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 install thermal actuators
• nipples with mounted PEX 3/4 x 16 type couplings
• venting and drain unit with automatic air vent

Flow meter:

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

Venting and drain unit:

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

What else should you buy for the air vent?

Additional accessories are needed for correct installation. Below, select the connecting 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

When laying pipes, we also recommend purchasing:

• Underfloor heating pipes
• Underfloor heating films
• Clips for fastening floor pipes
• Staplers and dispensers
• 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 specific packaging method depends on the number of pieces ordered and other items in the order. A standalone manifold will usually be packed in a cardboard box and stretch film.
