Expansion vessel for central heating, 5 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 vessel operates within a wide temperature range from -10°C to +100°C, so it copes well with typical seasonal changes in a heating system. A factory-set air chamber with a pre-charge of 1.5 bar supports correct system pressure, and the maximum working pressure of 8 bar fits most domestic and small commercial installations, giving the installer a safe operating margin.
The deep-drawn steel tank forms a robust, deformation-resistant body, while the replaceable EPDM membrane separates water from the air chamber and extends service life. When the membrane wears out, it can be replaced without changing the entire vessel, which reduces maintenance costs and downtime of the heating system.
This central heating expansion vessel is a practical choice for anyone looking for a durable, serviceable component for a closed heating circuit and a stable answer to the question of what pressure an expansion tank should maintain in everyday operation.
