1.3 SYSTEM DETAILS

Hot and Cold Water System

Pipe Sizing / Materials

To  achieve  even  distribution  of  the  available  supply  of  hot  and  cold  water,  it  is 
important in any mains pressure system, that the piping in a dwelling should be 
sized in accordance with BS 6700.  This is particularly important in a large property 
with more than one bathroom.

However,  the  following  rule  of  thumb  guide  lines  should  be  adequate  for  most 
smaller    property  types  as  long  as  water  pressures  are  within  the  recommended 
range of 2-3 bar.

1.    A  15mm  copper  or  equivalent  external  service  may  be  sufficient  for  a 
       small  1bathroom  dwelling  (depending  upon  the  flow  rate  available),  but 
       the minimum recommended size for new dwellings is 22mm (25mm MDPE).
2.    The  internal  cold  feed  from  the  main  incoming  stop  tap  to  the  BoilerMate 
       should  be  run  in  22mm  pipe.   The  cold  main  and  hot  draw-off  should  also 
       be run in 22mm as far as the branch to the bath tap.  
3.    The  final  branches  to  the  hand  basins  and  sinks  should  be  in  10mm  and  to 
       the  baths and showers in 15mm. (1 metre minimum)
4.    

We  would  recommend  that  best  results  for  a  balanced  system  are 

        achieved  by  fitting  appropriate  flow  regulators  to  each  hot  and  cold 
        outlet.  These MUST be fitted in cases where the final branch pipe sizes 
        are  not  as  recommended  in  item  3  or  water  pressures  are  above  the 
        recommended water  pressure  range  of  2-3  bar.    Details  of  suitable  flow 
        regulators  are provided in Appendix A.

Note:  If manifolds (available as an optional extra) are being used suitable flow 
regulators are automatically provided in the manifold and do not need to be 
provided at each outlet - See Appendix B for further details.

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 hot 
and  cold  water  systems  by  the  manufacturer  and  is  installed  fully  in  accordance 
with their recommendations.

This is particularly important in relation to use of push fit connections when using 
the optional flexible hose kits - see 2.2 Installation, Pipework connections.

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.

Taps/Shower Fittings

Aerated taps are recommended to prevent splashing.
Any  type  of  shower  mixing  valve  can  be  used  as  long  as  both  the  hot  and  cold 
supplies are mains fed.  However, all mains pressure systems are subject to dynamic 
changes particularly when other hot and cold taps/showers are opened and closed.  
To minimise the impact of this we would always recommend the use of thermostatic 
showers with this appliance.
The shower head provided must also be suitable for mains pressure supplies.
However, if it is proposed to use a ‘whole body’ or similar shower with a number of 
high flow/pressure outlets please discuss with the Gledhill technical department.

1.0 DESIGN

The hot water supply to a shower-mixing valve 
should be fed wherever practical directly from 
the  BoilerMate  2000  or  be  the  first  draw-off 
point  on  the  hot  circuit.   The  cold  supply 
to  a  shower-mixing  valve  should  wherever 
practical be fed directly from the rising mains 
via an independent branch.  The shower must 
incorporate  or  be  fitted  with  the  necessary 
check  valves  to  provide  back-syphonage 
protection  in  accordance  with  the  Water 
Regulations.  
The supply of hot and cold mains water directly 
to a bidet is permitted provided that it is of the 
over-rim  flushing  type  and  that  a  type ‘A’  air 
gap is incorporated.

Hot and Cold Water System.

If the length of the hot water draw off pipework 
is excessive and the delivery time will be more 
than 60 seconds before hot water is available 
at the tap, you may wish to consider using trace 
heating to the hot water pipework such as the 
Raychem HWAT system.  Please consult Gledhill 
Technical Department for further details.

It  is  important  that  the  cold  water  pipework 
is  adequately  separated/protected  from  any 
heating/hot  water  pipework  to  ensure  that 
the water remains  cold and of drinking water 
quality.
