Expansion vessel with replaceable membrane for closed heating systems.
The main purpose of the expansion tank is to compensate expansion due to the variation of the temperature in the heating system.
Expansion tank hoses, fittings and brackets are also available.
An expansion tank or expansion vessel is a small tank used to protect closed water heating systems and domestic hot water systems from excessive pressure. The tank is partially filled with air, whose compressibility cushions shock caused by water hammer and absorbs excess water pressure caused by thermal expansion.
