Note
■
In underfloor heating circuits, integrate a temperature
limiter on site for limiting the maximum temperature
of underfloor 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.
