To comply In all mains pressure installations it is important to remember that the incoming cold with this requirement: - supply must be shared between all terminal ﬁ ttings. It is important that a 22mm supply is brought to the appliance and a 22mm take-off is continued at least to the bath.

Page 25 INSTALLATION For maximising the use of the renewable ‘green’ energy, the system should be managed and controlled so that unnecessary ﬁ ring of the boiler is kept to a minimum. This can be achieved by a combination of householder use of the system and controls, for example; Use the store to provide shower or a bath to utilise the heat gained by the system from the previous day’s solar energy input.
