The control unit has integral ball valves to allow for
isolation from the primary heating system, an adjustable
blending valve and a 6 metre head circulation pump. An
anti-vibration mounting bracket ensures silent operation.
Speedfit push in connections make for a fast connection
to pipework.
Speedfit recommend connection to the main central
heating flow and return distribution system, but it is also
possible to connect to the nearest radiator supply pipe.
A full and detailed installation guide is provided with each unit.
The Speedfit Underfloor Heating Control Unit is suitable
for use when:
•The boiler serving the existing heating system has
the capacity to take the extra output from 2KW to 3KW
•The boiler is compatible with the additional pump
•The maximum area to be heated is 30 sq metres
The Control Unit is designed to be used with Speedfit
Barrier Pipe. The amount of pipe needed is determined
not only by the size and shape of the room but by the
resistance of the floor finish to heat transfer.
The table below shows examples of low resistance (tiles)
and high resistance (carpet with underlay) finishes.

.
The unit is pre-assembled and pre-wired
to allow for a fast and simple installation.
SOLID FLOOR INSTALLATIONS
The screed is an important and integral part of the UFH
system, transferring energy from the pipes to the area to
be heated. The response of this ‘thermal mass’ will depend
on its depth and make up.
The usual depth of screed is 65 - 75mm thick but it is possible
depths can be reduced to assist in improving performance.
SCREEDS
PIPE LAYOUT IN SOLID FLOOR INSTALLATIONS
The shape of the room and the position of the outside
walls and windows will determine the pattern of the pipe
layout. The counterflow pattern is recommended although
other options are shown below.
Single Serpentine Double Serpentine
Triple Serpentine Counterflow
INSTALLATION IS QUICK AND EASY
The floor is cleared
of dust and debris
and insulation is laid
across the area.
Speedfit Pipe is laid
in a
pre-determined
pattern and
fixed in
position with staples.
Fit the Speedfit Manifold
to the wall and connect the
Pump Pack.
Connect the ends of the
pipes to the Manifold.
The system is filled and
pressure tested.
The screed should be laid
whilst the pipe is pressurised.
The underfloor heating
system should not be used
to dry the concrete screed.

SPEEDFIT SYSTEM COMPONENTS
TIMBER FLOOR INSTALLATIONS
Spreader plates are available
for timber flooring which
uses either traditional
joists
or TJI joists.
Spreader plates 390mm x
1,000mm and 390mm x
250mm are designed for
use with traditional joists
at 400mm centres. They
are laid across the joists
and fixed in place using a
hand stapler. The 15mm
Speedfit Pipe is pushed
into the grooves in the
plate and the floor decking
laid on top.
Insulation can be placed
between joists to the
underside of the plates
either before or after the
plates have been laid.
Spreader plates 165mm x
1000mm can be used
with either traditional or
TJI joists and with the
floor already in place.
They are fixed to the
underside of the floor
using staples or screws.
The Speedfit Pipe is
fixed in to the groove.
When the plates and
pipework have been
installed, the insulation
is placed in the floor
void to minimise
downward heat loss.
