Space Heating
It is essential that an additional expansion vessel
is sized and fitted to the enlarged system. The
one provided is 4 litres.
This appliance is designed to provide a heating
output and this can be plumbed into the flow and
return connections on the left hand side of the
Heater.
The pump in the Heater is able to provide the circula-
tion required for all types of ‘heating’ circuit, radia-
tors, cylinders and fan coil units. The Heater also
includes an electric 3 port valve which determines
the flow of the heated water.
(See Fig 2.1)
The Heater’s control enables a priority to be selected
(See Commissioning page 17)
, Pool satisfied
before Heating or vice versa. The Heating tempera-
ture control on the front panel enables the maximum
flow temperature to be set.
The heating system should be installed in accord-
ance with current good practice, three example
designs are given in
Fig 2.2
The control will automatically reduce the output for
Heating to about 15% (~6kW). If this is insufficient it
can be increased in Service Mode
(See Fig 8.3 and Commissioning page 16 and
Fault Finding on page 23)

Condensate Drain
See Fig. 7.0, and 7.1
A 75mm condensate trap is provided in the Heater
and is satisfactory when connected to Soakaways,
Gullies, Rainwater Pipework and Internal Drainage
systems. All pipework and fittings in the condensate
drainage system MUST be made of plastic, unless
they carry other liquid waste.
No other materials
may be used.
The pipework should be insulated if
run out of doors.
The drain outlet on the boiler is :
40 mm Hunter waste pipe.
Pool Pump & Pipework
The Heater is an indirect design and uses two very
high performance heat exchangers. The pool water
passes through the Secondary, the water in the
Primary is completely separate. The Heater controls
modulate the input when approaching the set tem-
perature for greater accuracy and economy. It is
recommended that pool pump overrun is used to
maximise the life of the Heater.
If a new pump is being fitted consult the Pressure
Loss graph (
Fig 2.0
) to determine its size.
The Heater is provided with both 1½” and 50mm
plastic pool connections. As built the connections are
‘From Pool’ on the left, ‘To Pool’ on the right, how-
ever these can be easily reversed.
With the exception of automatic dosing equipment,
the Heater should be plumbed as the last piece of
equipment before the pool.
It is permissable to fit an isolating valves on the
pipework on either side of the Heater but in these
circumstances it is recommended to fit a flow switch
in the Heaters Mains supply.
