Underfloor Heating Manifold WIGELL, 9 circuits, stainless steel + manual air vent

Product detailed description

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 optional. 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 matched to 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 equipped 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 - option to install 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:

It is used to set the flow rate of heating water in l/min and thus 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. With these manual heads, it is not possible to regulate individual branches. The manual heads can be removed and replaced with electric actuators.

Air vent and drain unit:

It is used to vent air from 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 proper connection. Below, choose 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 an already 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 foils
• Clips for fixing underfloor pipes
• Staplers and dispensers
• Expansion strips for the wall

Packaging and delivery method

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