Connecting the heating circuits and condensate drain

Note
■ In underfloor heating circuits, integrate
a temperature limiter on site for limiting
the maximum temperature of under-
floor heating systems.
■ To ensure the minimum flow rate (see
specification), fit an overflow valve in
every heating circuit (except single
pipe heating circuits).
■ Equip the secondary circuit on site with
an expansion vessel.
