Components

Greenfloor PE-Xc pipe and manifolds
Greenfloor PE-Xc system pipe
Greenfloor PE-Xc system pipe
is available in two different
diameters and two different
lengths. There is a choice of
14mm dia. and 16mm dia. pipe,
each with a 2mm side wall.
The selection of the diameter
depends on each particular
installation and will be specified
as part of the package of information provided by the
Worcester Design Service. This is dependent upon
factors such as total pipe length and pressure loss
throughout the installation.
Domestic installers will find the 200m long coils the most
practical and easiest to work with. If installing regularly, for
example on construction sites, it may be more practical to
specify the larger coils which are available – 14mm dia. as a
750m coil or 16mm dia. as a 650m coil. These much larger
coils will reduce the amount of off-cuts. The coil is best
handled when using a pipe reel and stand which are available
from Worcester, and enables the pipe to be supported and
easily uncoiled.
Greenfloor PE-Xc system pipe is guaranteed for a period
of 25 years.
Greenfloor stainless steel manifolds
Greenfloor stainless steel
manifolds are available in a
range of sizes to accommodate
applications from 2 to 16 zones.
It is also possible to connect
two manifolds together. For
example if an extension to
the Greenfloor installation is
required, or to accommodate
unforeseen circumstances at
installation stage.
The number of ports required on the manifold depend
on a number of factors including:
•
The number of rooms in the property
•
The size of the rooms
•
The heat loss of the room and building
•
The heat output required from the floor
•
Limiting any one pipe run to no more than 120m,
from the manifold and back.
Greenfloor stainless steel manifolds feature flow connections
on the lower manifold section. Incorporated flow meters
allow each zone to be accurately commissioned.
The zone specifications and the optimum number of ports
will be provided in the package of information provided by
the Worcester Design Service.
The outlets of the manifold are ¾" and easily connect with
Greenfloor PE-Xc system pipe using ¾" to 14mm or 16mm
adaptors, according to the diameter of the pipe specified.
The upper manifold section contains the return connections,
again using ¾" adaptor fittings, the Greenfloor PE-Xc system
pipe can be easily connected. Each port on the return
manifold includes a 30mm threaded connection which
incorporates a manual isolating valve and is expected to be
replaced with a 230V actuator. This enables full control over
each zone using either a wired or wireless control platform
and wiring centre.
Each manifold section also features a fill and drain point
with a sealing cap provided, an automatic air vent and
1" connections to the chosen Greenfloor pump and
mixing station.
Greenfloor manifold cabinets
A Greenfloor manifold
cabinet may be specified
and selected to offer a
neat and tidy finish to
the installation.
Available as either flush
mounted, which can be
recessed into a wall prior
to final plastering taking
place, or surface mounted,
which fits directly to a
finished wall surface.
