WIGELL Underfloor Heating Manifold, 11 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 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 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 set consists of

Heating water body:

• flow meters ending with a nipple and a PEX 3/4 x 16 coupling
• air vent 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 - possibility of mounting thermal actuators
• nipples with mounted PEX 3/4 x 16 couplings
• air vent and drain unit with an automatic air vent

Flow meter:

It is used to set the heating water flow rate in l/min and thus 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, or shut it off completely. The transparent part of the flow meter shows the water level indicating the 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 cannot be used to regulate individual branches. The manual heads can be removed and replaced with electric actuators.

Air vent and drain unit:

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

What else to buy with the air vent?

Additional accessories are required for correct connection. Below, select the connection components 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 connection without a circulation pump
• Compression fittings

When laying the pipes, we also recommend purchasing:

• Underfloor heating pipes
• Underfloor heating foils
• Clips for securing underfloor pipes
• Staplers 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 that it is not damaged during transport. The exact packaging method depends on the number of ordered pieces and other items in the order. A standalone manifold will most often be packed in a cardboard box and stretch film.
