Underfloor Heating Manifold WIGELL, 3 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 a compression fitting, 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-regulating 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 regulating valves in two variants with thermometer preparation, either angled or straight.
• The manifold is fitted 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 draining unit with a manual 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-venting and draining unit with a manual air vent

Flow meter:

It is used to set the heating water flow rate in l/min and thus balance the pressure differences of the 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 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 draining unit:

It is used to vent air from the heating system. The air vent valve of this unit is manual (key-operated) and can be replaced with an automatic air vent valve.

What else to buy for the air vent?

Additional accessories are needed for proper connection. 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 a built-in pump
• Ball valves for connections 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 pipe reelers
• 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 specific method of packaging depends on the number of ordered pieces and other items in the order. A single manifold will most often be packed in a cardboard box and stretch film.
