Flat expansion vessel for central heating, 6 l, round
The flat expansion vessel for central heating is a compact solution for stabilising pressure in closed heating systems. Its round, space‑saving design with a 6‑litre capacity supports reliable operation of domestic boilers and radiators in everyday use.
The integrated SBR diaphragm separates water from the air chamber, reducing the risk of corrosion inside the tank and helping the installation maintain consistent pressure. A pre‑charge of 1.5 bar suits typical residential heating systems, while a maximum working pressure of 3 bar fits most standard applications in single‑family houses and small commercial spaces.
The vessel is made of deep‑drawn steel, which enhances structural strength and resistance to deformation during pressure fluctuations. The operating temperature range from -10°C to +90°C covers both low‑temperature and conventional heating circuits, so the product adapts well to modern boilers and mixed installations.
This flat expansion tank for heating systems is a practical choice for installers and homeowners looking for a durable, pressure‑stabilising component that supports safe, long‑term operation of the entire central heating installation.
