WIGELL Floor Heating Manifold, 3 circuits, stainless steel + automatic air vent

Product detailed description

Manifold for underfloor heating 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, in 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 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: double-adjustable 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 fitted with control valves, flow meters and air vents.

This manifold assembly consists of

Supply (heating) water body:

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

Return water body:

• thermostatic valves M30 x 1.5 - allows installation of thermal actuators
• nipples fitted with PEX 3/4 x 16 type couplings
• air vent and drain unit with automatic air vent

Flow meter:

It is used to set the flow rate of the heating water in l/min and thus balance the pressure differences of the individual heating circuits. Depending on the direction in which 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, individual branches cannot be regulated. 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 automatic, and can be replaced with a manual air vent valve.

What else to buy for the air vent?

Additional accessories are needed for proper connection. Below, select 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 films
• Clips for securing floor pipes
• Staple guns and dispensers
• Expansion strips for the wall

Packaging and delivery method

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