1.3 SYSTEM DETAILS
Heating System
Pipe Sizing/Materials
The SysteMate 2000 is designed to be installed with any condensing or non
condensing boiler which is suitable for a sealed heating system (i.e. fitted with an
overheat thermostat) and is capable of delivering hot water at a minimum of 80
o
C.
The primary pipework connecting the boiler and the thermal store should be sized
to achieve a maximum of 11°C rise across the boiler or the maximum temperature
rise specified by the boiler manufacturer, whichever is smaller, but in any instance it
should not be less than 22mm copper tube.
If the boiler is a condensing type the boiler must be set to operate at a normal 82
o
C
flow 71
o
C return system.
Note: There should be no valves in the pipework connecting the boiler to the
SysteMate 2000.
The heating circuit operates on the normal primary boiler temperatures i.e. 82°C
flow and 71°C return. Therefore any traditional hot water radiators or convectors
can be used with this system and no special over-sizing of the heat emitters is
necessary.
All the recommendations with regard to
pipework systems in this manual are generally
based on the use of BS/EN Standard copper
pipework and fittings.
However, we are happy that plastic pipework
systems can be used in place of copper
internally as long as the chosen system is
recommended for use on domestic heating
systems by the manufacturer and is installed
fully in accordance with their recommendations.
We always recommend the use of barrier pipe
for these systems.
It is also essential that if an alternative pipework
material/system is chosen the manufacturer
confirms that the design criteria of the new
system is at least equivalent to the use of BS/EN
Standard copper pipework and fittings.
Boiler Size
It is only necessary to calculate the heating
requirements in accordance with BS 5449. The
allowances shown below should be added
for domestic hot water. The control system
automatically gives priority to hot water when
necessary.
Boiler Sited Below SysteMate 2000
The flow pipe from the boiler to the SysteMate
2000 must rise continuously. No valve shall be
fitted in the primary flow pipe as this forms the
expansion pipe to the expansion vessel.
The size of the primary pipework connecting
the boiler to the SysteMate 2000 must not be
less than 22mm (or that specified by the boiler
manufacturer).
