Expansion vessel for central heating, 18 l, hanging
The wall-mounted expansion vessel for central heating is designed to stabilise pressure in closed heating systems and protect key components of the installation. Its compact form and red RAL 3000 finish suit technical rooms and boiler areas where reliability and clear identification of system elements matter.
The expansion tank operates within a wide temperature range from -10°C to +100°C, so it works both in cold start-up conditions and at high operating temperatures. A pre-charged air chamber set to 1.5 bar supports correct system balancing, while the maximum working pressure of 8 bar fits most domestic and small commercial heating installations.
The deep-drawn steel body offers high mechanical strength and resistance to deformation under load. Inside, a replaceable EPDM membrane separates water from the air chamber, extending service life and enabling straightforward maintenance instead of replacing the entire vessel. The hanging design integrates well with standard wall-mounted heating equipment.
This wall-mounted expansion vessel is a dependable choice for anyone configuring or upgrading a central heating system and looking for stable operating pressure, long-term durability and easy service access.
