Underfloor Manifold WIGELL, 5 circuits, stainless steel + manual 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 fluid 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 determined for the given number of circuits and fits perfectly.
• You can choose control valves 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 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 with mounted PEX 3/4 x 16 couplings
• air vent and drain unit with a manual (key-operated) 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 of heating water, or shut it off completely. The water level in 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. These manual heads cannot be used to regulate the 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 manual (key-operated), and it can be replaced with an automatic air vent valve.

What else should you buy for the air vent?

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

• Recessed and surface-mounted cabinets
• Mixing sets (WILO pump + ESBE valve) - for variants without an already 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 dispensers
• Expansion strips for the wall

Packaging and delivery method

We will deliver the product to you via standard parcel shipping and it will be packaged so that it is not damaged during transport. The actual packaging method depends on the number of ordered pieces and other order items. A standalone manifold will most commonly be packaged in a cardboard box and stretch film.
