2 8 Typical water system schematics

Layout 1: circuit with thermal module directly linked to heating system (check that the pump's discharge head
is sufficient to ensure adequate circulation)
Layout 2: circuit with thermal module directly linked to heating system and DHW tank (check that the pump's
discharge head is sufficient to ensure adequate circulation)

Domestic hot water and central heating circuits must be completed with expansion vessels of adequate capacity
and suitable, correctly-sized safety valves. The discharge of safety valves and appliances must be connected to a
suitable collection and disposal system (see Catalogue for compatible accessories).
b
The choice of system components and the method of their installation are left up to the heating engineer installing
the system. Installers must use their expertise to ensure proper installation and functioning in conformity to all ap-
plicable legislation.
b
Special supply/refill water must be conditioned using suitable treatment systems.
