The wall-mounted expansion vessel for central heating is designed to stabilise pressure in closed heating systems and protect the installation from overload. Its compact form suits both new systems and modernisation projects, supporting efficient and safe operation of the boiler and radiators.
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 helps maintain correct system pressure, an important aspect for anyone wondering what pressure an expansion tank should have in a central heating installation.
The deep-drawn steel tank 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 simplifying maintenance. The maximum working pressure of 8 bar suits most domestic and small commercial heating systems.
The red RAL 3000 finish gives the expansion vessel a clear, technical look that fits boiler rooms and service spaces. It is a solid choice for investors and installers who expect reliable pressure control, durable materials and convenient long-term operation of the heating system.
