Expansion vessel for central heating, 12 l, hanging
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 boiler rooms and modernised systems, supporting efficient and safe operation of the heating circuit.
The pre-charged air chamber set to 1.5 bar helps maintain the correct operating pressure in typical domestic installations, answering common questions about what pressure an expansion tank should have. A maximum working pressure of 8 bar gives a comfortable safety margin for most heating systems, while the operating temperature range from -10°C to +100°C supports year-round use.
The deep-drawn steel tank offers high mechanical strength and resistance to deformation, even under variable loads. The replaceable EPDM membrane separates water from the air chamber, extending service life and simplifying maintenance, as only the membrane needs replacement instead of the entire vessel. The red RAL 3000 finish fits standard heating components and keeps the installation visually consistent.
This expansion vessel is a reliable choice for installers and homeowners who expect stable pressure control, durable materials and convenient servicing in central heating systems.
