WIGELL Floor Heating Manifold, 13 circuits, brass + automatic air vent

Product detailed description

The 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 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 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, lockable

Advantages of Wigell manifolds

• Each manifold undergoes a pressure test, which ensures its reliability and long service life.
• You can choose between a manual or automatic air vent.
• The cabinet size is precisely matched to the given number of circuits and fits perfectly.
• The regulating valves can be chosen in two variants with thermometer preparation, either angled or straight.
• The manifold is equipped with regulating valves, flow meters and air vents.

This manifold assembly consists of

Heating water body:

• flow meters ending in a nipple and a PEX 3/4 x 16 coupling
• air venting and drain unit with an 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 fitted with PEX 3/4 x 16 couplings
• air venting and drain unit with an automatic air vent

Flow meter:

It is used to set the heating water flow rate in l/min and thereby 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 heating water flow rate, 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. 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:

It is used to vent air from the heating system. This unit's air vent is automatic, and can be replaced with a key-operated air vent.

What else to buy with the air vent?

Additional accessories are needed for correct installation. Below, choose the connection parts 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 pipes, we also recommend purchasing:

• Underfloor heating pipes
• Underfloor heating foils
• Clips for securing underfloor pipes
• Staplers and pipe dispensers
• Expansion tapes for the wall

Packaging and delivery method

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