WIGELL Floor Manifold, 11 circuits, stainless steel + manual air vent

Product detailed description

The underfloor heating manifold is the main component for the even distribution of 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 a diameter 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-regulation with lockable option

Advantages of Wigell manifolds

• Each manifold undergoes a pressure test, which ensures its reliability and long service life.
• You can choose a manual or automatic air vent.
• The cabinet size is precisely designed for the given number of circuits and fits perfectly.
• You can choose control valves in two variants with a 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 a PEX 3/4 x 16 coupling
• air-vent and drain unit with a manual key-operated air vent (an automatic air vent can also be used)

Return water body:

• thermostatic valves M30 x 1.5 - possibility of installing thermal actuators
• nipples fitted with PEX 3/4 x 16 couplings
• air-vent and drain unit with a manual key-operated air vent

Flow meter:

Used to set the heating water flow rate in l/min and thus balance the pressure differences of the individual heating circuits. Depending on the direction you turn the lower part of the flow meter, you decrease or increase the heating water flow rate, or shut it off completely. The water level on the transparent part of the flow meter shows the water flow rate 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. Individual branches cannot be regulated with these manual heads. The manual heads can be removed and replaced with electric actuators.

Air-vent and drain unit:

Used to vent air from the heating system. The air vent valve of this unit is manual (key-operated) and can be replaced with an automatic air vent valve.

What else to buy for the air vent?

Additional accessories are needed for correct installation. Below, select the connection components that are fully compatible with this manifold:

• Flush-mounted 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 the pipes, we also recommend purchasing:

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

Packaging and delivery method

The product will be delivered to you by standard parcel delivery and will be packaged so that it is not damaged during transport. The exact packaging method depends on the number of ordered pieces and other items in the order. A standalone manifold will most often be packed in a cardboard box and stretch film.
