Plan Of Appliance Connections

The BoilerMate CP units are supplied on an 

installation base to allow the pipe runs to 

connect to the appliance from any direction.  

It is easier if all pipes protrude vertically in the 

cut out area shown. Compression or push fit 

connections can be used. All pipe positions 

are approximate and subject to a tolerance of 

+/- 10mm in any direction. Space will also be 

required for a 22mm cold water supply and a 

22mm warning / overflow pipe (if the optional 

extra ball valve and overflow connector have 

been specified. If a warning/overflow pipe 

is NOT provided the F&E Cistern should be 

filled from a temporary hose connection 

incorporating a double check valve. This can 

be from a temporary hose connection supplied 

from a cold water tap or a permanent cold 

branch provided adjacent to the Top up Cistern. 

The temporary connection must be removed 

once the appliance is filled.

Note: All dimensions are shown in mm and 

are to the centre line of the pipework.

Hot and Cold Water System

General

A schematic layout of the hot and cold water services in a typical small dwelling is 

shown below.  BoilerMate CP will operate at mains pressures as low as 1 bar and as 

high as 5 bar although the recommended range is 2-3 bar dynamic at the appliance.  

It is also important to check that all other equipment and components in the hot 

and cold water system are capable of accepting the mains pressure available to the 

property.   If the mains pressure can rise above 5 bar or the maximum working pressure 

of any item of equipment or component to be fitted in the system, a pressure limiting 

(reducing) valve set to 3 bar will be required.

If you encounter a situation where the water pressure is adequate but flow rates are 

poor please contact our technical helpline for details of an effective solution.

Note

 : Each BoilerMate CP is fitted with a strainer and flow regulator on the cold mains 

supply connection.  If the supply pressure is less than 2 bar or if all taps are provided 

with flow regulators the flow regulator on the cold inlet should be removed.

No check valve or similar device should be fitted on the cold water supply branch to 

the BoilerMate CP.

The hot water flow rate from the BoilerMate CP is directly related to the adequacy of the 

cold water supply to the dwelling. This must be capable of providing for those services, 

which could be required to be supplied simultaneously, and this maximum demand 

should be calculated using procedures defined in BS EN 806:1-5: BS EN 8558:2011.

If a water meter is fitted in the service pipe, it should have a nominal rating to match 

the maximum hot and cold water peak demands calculated in accordance with BS 

EN 806:1-5: BS EN 8558:2011. Please note, the BoilerMate CP is fitted with a 15 l/m 

flow restrictor.

Note:  

The diagram below shows the top up 

cistern with ballvalve and warning/overflow 

pipe which can be supplied as an optional extra 

if required. However, the standard preferred 

arrangement is for the cistern to be manually 

filled from a temporary hose connection fitted 

with a double check valve. 

The cistern must not be fitted more than 10 

metres above the BoilerMate CP appliance itself.
