Specifications

Pipe Laid 100mm from
face of wall to avoid
fixings etc
UFH Circuit Return
UFH Circuit Flow
Pipe Laid @ 200mm
centres
TYPICAL PIPE LAYOUT DETAIL 1 "COUNTERFLOW" PATTERN
Flow pipe laid next to
external wall first
Installation Notes
- Pipe normally laid
in floor at 200mm
centres.
- Uses only 90° bends
which reduces mechanical
stress on tube.
- Suitable for any size &
shape area.
- Not Suitable for battened
floors
- Provides even temperature
distribution across flow as
flow & returns altenate.
Installation Notes
- As detail 1 other than
pipe normally laid in floor
at 200mm centres with
closer pipe spacing of
100mm at high heatloss
areas as determined
by design criteria.
(refer to manifold installation
data sheets supplied with
final quote)
TYPICAL PIPE LAYOUT DETAIL 2
"COUNTERFLOW" PATTERN WITH PERIMETER ZONE.
UFH Circuit Return
UFH Circuit Flow
Perimeter Zone as part of
main circuit. Closer pipe
spacing of 100mm centres
in strip max 1m wide
(BSEN1264).
Installation Notes
- Pipe normally laid in floor at
200mm centres.
- Uses only 90° & 180° bends
which requires min 175mm
bending radius must be observed
to minimise mechanical stress on tube.
- Suitable for large open areas.
- Suitable for battened / screed floors
- Provides relatively even temperature
distribution across flow as
flow & returns altenate.
- Perimeter zones difficult to achieve
if specified.

TYPICAL PIPE LAYOUT DETAIL 4
"SINGLE SERPENTINE / SINGLE MEANDER" PATTERN
Installation Notes
- Pipe normally laid in floor at 200mm
centres.
- Uses only 180° bends
which requires min 175mm
bending radius must be observed
to minimise mechanical stress on tube.
- Suitable for any shape / area.
- Suitable for battened / screed floors
- Heat output is concentrated in part of area.
- Perimeter zones difficult to achieve
if specified.
