Product Description
These Potable Expansion Vessels are built from different materials than our Red Heating Expansion Vessels to ensure that the water is contaminant free and safe for human consumption.
The most common use for an expansion vessel in a potable application would be in an Unvented Water Heater or a Pumped System.
Expansion Vessels operate on the basis that the internal chamber is separated by a rubber membrane, inside this membrane sits the water and surrounding this sits a pocket of air.
As the water inside the sealed system is pressurised, as water is non compressible, the air inside the air chamber of the Expansion Vessel will become compressed thus leaving the system safe from over pressurisation.
Expansion Vessels are commonly used on pumped systems to remove the requirements of a continuous pump. This works as the user will set a low and high pressure on the pump settings, when the water pressure reaches the lowest setting the pump will engage and fill the Expansion Vessel to the high pressure point and stop.
Once this cycle has been completed the Expansion Vessel puts the stored water under pressure ensuring higher pressure water. This will continue until the Expansion Vessels pressure drops to the lower point and the pump starts its cycle again.

- Operates between -10°C and +100°C
