This Pressure Tank Expansion Vessel is a small tank used to protect closed (not open to atmospheric pressure) water heating systems & domestic hot water systems from excessive pressure. The tank is partially filled with air, whose compressibility cushions shock caused by water hammer. It also absorbs excess water pressure caused by thermal expansion.
Expansion Vessels operate on the basis that the internal chamber is separated by a rubber membrane; inside this membrane sits the water (surrounding this sits a pocket of air). As the water inside the sealed system is heated, the water pressure increases. Being that water is non compressible, the air inside the air chamber of the Expansion Vessel will become compressed, thus leaving the system safe from over pressurization. As water can increase by 4.5% volume when heated from 0-100° C, a Expansion Vessel is a vital part of any sealed heating system.
Not for use with potable water.
