Flat expansion vessel for central heating, 8 l, rectangular
The flat expansion vessel for central heating is a compact, rectangular tank designed to stabilise pressure in closed heating systems. With a capacity of 8 litres, it supports efficient operation of domestic boilers and radiators, protecting the installation from pressure fluctuations and extending its service life.
The integrated air chamber is factory set to a pre-charge pressure of 1.5 bar, so the vessel works reliably in typical residential systems. Operating temperatures from -10°C to +90°C suit both low-temperature and standard heating circuits, while the maximum working pressure of 3 bar matches common requirements for a central heating expansion tank.
The vessel is made of deep-drawn steel, which provides a robust, deformation-resistant body even under long-term load. An SBR membrane separates water from the air chamber, reducing the risk of corrosion inside the tank and supporting stable performance over many heating seasons. The flat, rectangular form fits neatly against walls or inside boiler casings, leaving more usable space in the installation area.
This flat expansion vessel is a practical choice for installers and homeowners looking for a durable, space-saving solution for central heating systems and for anyone selecting the right expansion tank pressure setting for safe, everyday operation.
