WIGELL Underfloor Heating Manifold, 12 circuits, stainless steel + automatic air vent

Product detailed description

Underfloor heating manifold is the main component for even heat distribution 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 can be chosen freely. This manifold allows you to connect PeX-AL-PeX or Pe-rt pipes using compression fittings.

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

• Every manifold undergoes a pressure test, ensuring its reliability and long service life.
• You can choose either 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 a thermometer preparation, either angled or straight.
• The manifold is fitted with control valves, flow meters and air vents.

This manifold set consists of

Heating water body:

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

Return water body:

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

Flow meter:

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

Air venting and drain unit:

Used for venting air from the heating system. The air vent valve of this unit is automatic, and can be replaced with a manual air vent valve.

What else to buy for the air vent?

Additional accessories are required for proper installation. 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 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 dispensers
• Expansion tapes for the wall

Packaging and delivery method

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