Expansion vessel for drinking water (hot or cold) HYDROCHAUD

HYDROCHAUD vessels are used for hot or cold water installations; they are particularly suited to domestic hot water networks. They absorb the increase in water volume (temperature rise or pressure increase), which eliminates the discharge of hot water through the water heater safety unit. Using a HYDROCHAUD vessel ensures constant pressure and hot water available immediately at the tap.
