WIGELL Floor Manifold, 12 circuits, brass + 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 diameters of 16–20 mm.

Wigell manifolds can be mounted directly on a wall or, using the supplied brackets, into a manifold cabinet. The mounting position is arbitrary. You can connect PeX-AL-PeX or Pe-rt pipes to this manifold 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-control with locking option

Advantages of Wigell manifolds

• Every 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.
• 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 assembly consists of

Heating water body:

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

Return water body:

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

Flow meter:

It is used to set the heating water flow rate in l/min, thereby balancing 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, or shut it off completely. The water level in the transparent part of the flow meter 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 draining unit:

Used to vent the heating system. The air vent valve of this unit is automatic, and it can be replaced with a key-operated air vent valve.

What else to buy for the air vent?

Additional accessories are needed for proper connection. Below, select the connecting parts 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 securing floor pipes
• Staplers and 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 that it is not damaged during transport. The actual 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.
